Occupant Protection for Automated 
Driving Systems 
AGENCY : National Highway Traffic 
Safety Administration (NHTSA), Department of Transportation. 
ACTION : Notice of proposed rulemaking 
(NPRM). 
SUMMARY : This proposal is one of a 
series of regulatory actions that NHTSA is considering to address the near- and long-term challenges of testing and verifying compliance with the Federal motor vehicle safety standards (FMVSS) for vehicles equipped with Automated Driving Systems (ADS) that lack the traditional manual controls necessary for human drivers, but that are otherwise traditional vehicles with typical seating configurations. This document seeks to clarify the ambiguities in applying current crashworthiness standards to ADS- equipped vehicles without traditional manual controls, while maintaining the regulatory text’s application to more traditional vehicles and vehicles equipped with ADS that may have alternate modes. This proposal is limited to the crashworthiness standards and provides a unified set of proposed regulatory text applicable to vehicles with and without ADS functionality. This NPRM builds on NHTSA’s efforts to identify and address regulatory barriers to vehicles with unique designs that are equipped with ADS technologies, including the advance notice of proposed rulemaking on removing barriers in the crash avoidance (100 Series) FMVSS in May 2019, the request for comments on this topic in January 2018, and the research that NHTSA is currently conducting. NHTSA also intends to issue a separate notice regarding removal of barriers in the FMVSS that pertain to telltales, indicators, alerts, and warnings in ADS- equipped vehicles.

I. Executive Summary 
The National Highway Traffic Safety 
Administration (NHTSA) is proposing to modernize many of its current crashworthiness
1(200 Series) Federal 
motor vehicle safety standards (FMVSSs) to remove unnecessary barriers to Automated Driving System- equipped vehicles (ADS-equipped 
vehicles) and the unconventional interior designs that are expected to accompany these vehicles, including the lack of driving controls.
2This document and the modifications to the regulatory text discussed within it also take into account some dual-mode ADS-equipped vehicles, as defined by SAE International (SAE).
3 
NHTSA’s safety mission requires the 
agency to prioritize actions that reduce traffic accidents and deaths and injuries resulting from motor vehicle crashes.
4 
Enabling innovation with lifesaving potential is also a priority for the agency, and the agency believes that ADS-equipped vehicles may have lifesaving potential. Even so, as much of this potential is currently unsubstantiated and the impacts unknown, the agency believes the most prudent path forward is to remove unnecessary barriers to innovation while ensuring that occupants continue to receive the same protections afforded by existing regulations. Specifically, this Notice of Proposed Rulemaking (NPRM) proposes to modernize portions of the FMVSSs listed below, by making definitional or textual changes. We have tentatively determined that changes are not required for the remainder of the 200 Series FMVSS to achieve the goal of this NPRM, but NHTSA seeks comment as to whether additional changes are necessary or appropriate and all other aspects of this proposal. 
—FMVSS No. 201; Occupant protection 
in interior impact. 
—FMVSS No. 203; Impact protection for 
the driver from the steering control 
system. 
—FMVSS No. 204; Steering control 
rearward displacement. 
—FMVSS No. 205, Glazing materials. 
—FMVSS No. 206; Door locks and door 
retention components. 
—FMVSS No. 207; Seating systems. —FMVSS No. 208; Occupant crash 
protection. 
—FMVSS No. 214; Side impact 
protection. 
—FMVSS No. 216a; Roof crush 
resistance; Upgraded standard. 
—FMVSS No. 225; Child restraint 
anchorage systems. 
—FMVSS No. 226; Ejection Mitigation. 
The modifications proposed in this 
document accomplish several high-level 
changes that span one or more of the standards listed above and are discussed in greater detail in Section VI. 
The first high-level change is the 
modification, addition, or relocation of key definitions throughout 49 CFR part 571. This proposal defines ‘‘driver air bag,’’ ‘‘driver dummy,’’ ‘‘driver’s designated seating position,’’ ‘‘passenger seating position,’’ and ‘‘steering control system.’’ These definitions become the supporting definitions that clarify application of the FMVSSs to ADS- equipped vehicles while maintaining their application to traditional vehicles and minimizing textual disruption. NHTSA also proposes to add a new term, ‘‘manually-operated driving controls’’ and move the definition of ‘‘row’’ from FMVSS No. 226 to Part 571.3. In addition, NHTSA proposes to move the definition of ‘‘steering control system’’ from FMVSS No. 203 to Part 571.3. 
Second, this proposal clarifies the 
application of some occupant protection standards to vehicles designed to carry objects, not occupants,
5and clarifies the 
applicability of standards designed to protect drivers from injury from the steering control system. The rationale behind these changes is that a vehicle that will only carry things, not people, would not require the protections currently in place that are designed to protect occupants. Vehicles not designed to carry occupants may require different protections to be in place, which are not the subject of this document. 
Third, this proposal addresses the 
protections required when there is not a steering wheel or steering column in a motor vehicle. The rationale discussed in this document is that an occupant should not need protection from a steering control system if none exists in that vehicle. 
Fourth, this document proposes to 
modify the regulatory text to address situations where there may be no driver’s seat and multiple outboard passenger seats. This is accomplished primarily through the definitional modifications discussed in the first point, above. 
Fifth, this proposal discusses the 
treatment of advanced air bags and advanced air bag suppression telltales

11The term ‘driver’ is defined in § 571.3 as 
follows: ‘‘Driver means the occupant of the motor vehicle seated immediately behind the steering control system.’’ 
12The task award document states ‘‘[t]he overall 
goal of this Task Order is to provide NHTSA findings and results needed to make informed decisions regarding the modification of FMVSS in relation to the certification and compliance verification of innovative new vehicle designs precipitated by automated driving systems.’’ 13 should be properly restrained in rear 
seating rows. 
Additionally, this document discusses 
and proposes modifications to the regulatory text where it currently uses the driver’s seat or the steering control as a spatial reference point for other locations in the vehicle. Buses, dummy placement for vehicles with bench seats, and characterizing the side of a vehicle based upon proximity and orientation to the driver’s seat are all discussed in detail. 
Finally, this proposal makes some 
minor editorial revisions and some clarifying modifications to ensure that industry and the public have a clear idea of how the occupant protection standards apply to ADS-equipped vehicles. 
NHTSA developed this notice of 
proposed rulemaking in consideration of comments the agency received in response to its January 18, 2018 Request for Comments notice (RFC), which sought to identify regulatory barriers in existing FMVSSs to the testing and compliance verification of ADS- equipped vehicles with unconventional interior designs.
7Comments received 
from the RFC indicate that there is a belief that many of the regulatory barriers to certification of ADS vehicles in crashworthiness standards do not require research because they are primarily related to a clarification of terminology, particularly for ‘‘driver’’ related terms. Commenters also seemed aligned with the concept that the crash 
protection afforded front seat occupants should be maintained for ADS vehicles. A more thorough discussion of the comments follows in later sections of this document. 
The primary goal of this NPRM is to 
modify the existing FMVSS in a way that both maintains the occupant protection performance currently required by the 200 Series FMVSS while also providing regulatory certainty for manufacturers developing ADS- equipped vehicles and reducing unnecessary barriers and costs. NHTSA proposes to achieve this goal by primarily making textual and definitional changes throughout the 200 Series FMVSS and in 49 CFR 571.3. The proposed changes are based on the public feedback obtained through the RFC and information provided by stakeholders involved in ongoing NHTSA research. 
In this NPRM, the agency explains 
(with examples) its reasoning behind the various modifications of the regulatory text being proposed and why the agency has opted not to propose other changes. NHTSA notes that, while 
the proposed regulatory text modifications are included in this document, the agency will provide in the docket for this NPRM a supplemental document that contains the full regulatory text of each modified standard, illustrating the added and deleted regulatory text to ensure that the precise changes proposed are available to commenters with the full context of the unmodified regulatory text. This supplemental document is intended to aid the public by providing a side-by- side comparison of both the current and proposed regulatory text. 
Although this proposal attempts to 
resolve most of the barriers present in the occupant protection FMVSS, it does not address telltales and warnings as they relate to ADS vehicles where there is no requirement for any occupant to be seated in what is currently considered the driver’s designated seating position (i.e., driver’s seat). This is a broad topic 
that will be discussed in a future notice focused solely on these issues, where the agency can engage the stakeholder community on those issues requiring additional policy and technical discussion.
8The one exception to this 
statement is the availability of the telltale related to the suppression of frontal passenger air bags, which will be discussed in this document. 
II. Background 
The National Traffic and Motor 
Vehicle Safety Act (49 U.S.C. chapter 
301) (‘‘Safety Act’’) prohibits regulated entities from manufacturing for sale, selling, offering for sale, introducing or delivering in interstate commerce, or importing into the United States any motor vehicle or equipment that does not comply with the FMVSSs.
9There 
are currently more than 60 FMVSSs that establish performance requirements to address a wide array of safety issues, such as occupant crash protection, fire protection, electrical protection, crash avoidance, and pedestrian safety. Almost all of these FMVSSs were promulgated long before vehicles equipped with ADS were contemplated, and thus, include a variety of assumptions surrounding who would be driving a vehicle, that the vehicle would have human occupants, and what protections drivers and occupants might need. Due to these assumptions, there are many actual and perceived barriers 
to the unique vehicle designs that are expected to accompany ADS-equipped 
vehicles that exist throughout the FMVSSs. 
a. NHTSA’s Prior Research and Public 
Engagement Efforts 
NHTSA has spent the last several 
years evaluating its regulations as they apply to vehicles equipped with ADS, with the primary focus on identifying potential barriers. The agency has also conducted research and engaged the public through a variety of means to further inform its evaluation of the FMVSSs. NHTSA, in collaboration with the Volpe National Transportation Systems Center, conducted a preliminary report identifying barriers to the compliance testing and self- certification of ADS-equipped vehicles without traditional manual controls. In March 2016, that report was published (the ‘‘Volpe Report’’).
10The report 
focused on FMVSS requirements that present barriers due to references to humans throughout those standards.
11 
Based on the Volpe Report findings, 
in 2017, NHTSA initiated work with the Virginia Tech Transportation Institute (VTTI) to expand upon the report by performing analysis and industry outreach to identify potential approaches for addressing certification and compliance verification barriers.
12 
Through this contract with NHTSA, VTTI taking a broader look at possible modifications to the current FMVSS regulatory text and test procedures that would both maintain safety and ensure regulatory certainty for manufacturers of ADS-equipped vehicles without traditional manual controls. 
The agency and the Department of 
Transportation (DOT) have also issued guidance focused on various aspects of 
ADS safety and safety of automation across the transportation sector. In September 2017, NHTSA and DOT released the guidance document Automated Driving Systems 2.0: A Vision for Safety to provide guidance to the public, particularly industry stakeholders and the States. A Vision for Safety discussed 12 priority safety

Safety Technologies and Associated Federal Motor 
Vehicle Safety Standards, 1960 to 2012,’’ January 2015. 15Three of the four exemption bases require that 
the manufacturer make some sort of documentary 
showing regarding the level of safety of the exempted vehicle. The remaining basis requires that the manufacturer show that an exemption is needed to avoid substantial economic hardship. 
16We note that some of these standards include 
requirements for telltales or alerts, which would not be affected by the changes proposed in this notice, 
Continued design elements for manufacturers and 
other innovators involved in ADS development, including vehicle cybersecurity, human machine interface, crashworthiness, consumer education and training, and post-crash ADS behavior. In October 2018, DOT released Preparing for the Future of 
Transportation: Automated Vehicle 3.0, a complementary document to the 2017 guidance that introduces guiding principles that will support Departmental programs and policies and describes the DOT’s multi-modal strategy to address existing barriers to safety innovation and progress. It also communicates DOT’s agenda to the public and stakeholders on important policy issues and identifies opportunities for cross-modal collaboration. DOT’s automation principles are: (1) We will prioritize safety; (2) We will remain technology neutral; (3) We will modernize regulations; (4) We will encourage a consistent regulatory and operational environment; (5) We will prepare proactively for automation; and (6) We will protect and enhance the freedoms enjoyed by Americans. 
NHTSA and DOT have engaged 
stakeholders by holding several public events on topics surrounding vehicles equipped with ADS. On December 7, 2017, DOT hosted a roundtable on voluntary data exchanges to accelerate the safe deployment of vehicles equipped with ADS. Later, on March 1, 2018, DOT held a public listening session on automated vehicle policy to seek input on the development of Preparing for the Future of Transportation: Automated Vehicles 3.0. On March 6, 2018, NHTSA held a 
public meeting on regulatory barriers in the existing FMVSSs to the vehicles equipped with ADS and that have certain unconventional interior designs. NHTSA, coordinating with VTTI, also held two multi-day public meetings on FMVSS considerations for ADS, to ensure that the agency was considering all viable options for the modernization of current FMVSS text and test procedures. 
Additionally, NHTSA has issued 
several notices in the last two years on issues surrounding the development and deployment of ADSs. One of which was a RFC on how best the agency should approach updating its standards, which is described in more detail in sections below. The second notice was an advance notice of proposed rulemaking (ANPRM) soliciting information from the public about whether and how best to develop a 
national pilot program for testing ADS- equipped vehicles in a safe manner. Third, NHTSA issued an ANPRM 
requesting information from the public on modernizing NHTSA crash avoidance standards (100 Series FMVSS) by removing unnecessary and unintended barriers.
13 
While the agency works to identify 
unnecessary restrictions on nascent technologies with life-saving potential, it also recognizes that many of the protections that today’s FMVSSs provide are broadly applicable to all vehicles, including ADS-equipped vehicles. The crashworthiness and occupant protection standards that NHTSA has put in place are examples of such standards. These standards and the associated technologies utilized in these standards have provided protections that have saved hundreds of thousands of lives over the last 50 plus years and the agency believes that the occupants of ADS-equipped vehicles also need such protections since even a perfectly designed ADS will not be able to avoid all crashes.
14Thus, the 
agency’s approach for the 200 Series FMVSSs is to clarify the unintentional barriers to innovation, ensure current protections are enjoyed by occupants of ADS-equipped vehicles, and conduct additional research on the remaining FMVSSs and occupant protection issues the agency is not currently able to address with textual or definitional changes. For occupant protection, some of the issues that require further research include novel seating arrangements (e.g., campfire seating; 
carriage-style seating), novel occupant seating postures (e.g., lay flat seating), 
rear seat protections, occupant seat use patterns, and transitions of traditional manual controls in dual-mode ADS- equipped vehicles (i.e., driving controls 
that can be stowed away while an ADS controls the vehicle). 
b. Impact of This NPRM on Current and 
Future Petitions for Exemption 
Until NHTSA comprehensively 
amends all the FMVSSs to not explicitly or implicitly require manual controls, NHTSA expects that manufacturers of ADS-equipped vehicles without traditional manual controls will seek exemptions from those FMVSS requirements that implicitly or explicitly require manual controls. In addition, we believe that uncertainty related to the certifications of ADS- equipped vehicles with driving controls will result in exemption requests. NHTSA has statutory authority under 49 U.S.C. 30113 to grant manufacturers 
exemptions from FMVSS and Bumper Standard requirements for limited number of vehicles. NHTSA may only grant an exemption if a manufacturer demonstrates that an exemption would be in the public interest, would be consistent with the Safety Act, and would qualify under at least one of four enumerated statutory bases.
15NHTSA 
has promulgated regulations formalizing the procedures manufacturers must follow to seek an exemption at 49 CFR part 555. 
Manufacturers applying for an 
exemption under 49 U.S.C. 30113 must make all the statutorily required showings for each FMVSS requirement with which an exempted vehicle would not comply. Given the number of FMVSS requirements that currently require or assume the presence of a driver or make reference to things such as the driver’s seat, driver air bag or driver dummy, NHTSA expects that manufacturers of ADS-equipped vehicles could potentially need to seek exemptions from dozens of FMVSS requirements. 
The proposed changes in this 
document will not eliminate the need for manufacturers of ADS-equipped vehicles to seek exemptions. However, the proposed changes could make the exemption process more efficient by reducing the number of standards from which manufacturers of ADS-equipped vehicles must seek exemption, while maintaining the existing level of occupant protection provided by the current FMVSSs. The recent exemption petition from General Motors (GM) for their Zero-Emission Autonomous Vehicle (ZEAV), 84 FR 10182, provides an illustrative example of how this proposal could impact the exemption process. In that petition, GM requested exemption from 16 FMVSSs, six of which are crashworthiness standards that would be affected by this proposal (FMVSS Nos. 203, 204, 207, 208, 214, and 226). If the changes proposed by this document had been finalized at the time GM submitted its application, many of the requirements in these six standards either would not have applied to the ZEAV, or would have provided compliance options that would have allowed for certification.

29Docket No. NHTSA–2018–0009–0089, 
available at https://www.regulations.gov/ document?D=NHTSA-2018-0009-0089. c. ADS Barriers Request for Comment 
To begin the rulemaking process, 
NHTSA published a RFC on January 18, 
2018.17This RFC requested information 
from the public to assist the agency in identifying any potential barriers in the existing FMVSS to the testing and compliance verification of ADS- equipped vehicles and certain unconventional interior designs that could be addressed without adversely affecting safety. That document focused primarily on vehicles equipped with ADS that lack certain controls that humans would use to control and navigate vehicles, such as brake pedals, steering wheels, and accelerator pedals. NHTSA solicited public input on how best the agency could approach the evaluation of current FMVSSs. The RFC asked a series of questions on identified and as of yet unidentified barriers in the FMVSSs, test procedure modifications, research issues, and how the agency should prioritize its research and rulemaking efforts. NHTSA’s goal in publishing the RFC was to collect the information necessary to develop proposals to modernize its standards and launch research to support such proposals. Comments received in response to the RFC that are applicable to this proposal are summarized below. 
d. Summary of Comments Received in 
Response to the ADS Barriers RFC That Apply to This Proposal 
The majority of comments received 
supported the concept of updating the FMVSSs, though some expressed concern with the timing of doing so. The Advocates for Highway and Auto Safety (‘‘Advocates’’) expressed concern with NHTSA working to remove barriers to ADS-equipped
18vehicles before 
evaluating the safety of vehicles equipped with ADSs and developing 
standards to govern the ADS’s performance.
19The Center for Auto 
Safety agreed and commented that NHTSA and DOT should develop and put in place safeguards to protect the public from ADS-equipped vehicles before removing barriers.
20The Center 
for Auto Safety commented that the 
American public have expressed discomfort and apprehension regarding ADS-equipped vehicles, and that safety should be NHTSA’s primary focus, not ‘‘paving the way for the success of businesses’’ in the ADS market.
21 
Consumer Watchdog echoed these 
concerns and added that it believes NHTSA is violating its safety mission by removing barriers.
22Consumer 
Watchdog stated that NHTSA should remove the ‘‘right barriers’’ and conduct research to develop new regulations of vehicles equipped with ADSs. 
The agency agrees that focusing on 
the removal of the ‘‘right’’ barriers is the first step, and the approach taken in this document makes as minimal changes as possible, while also making sure the occupant protections currently in place remain in place to benefit occupants of ADS-equipped vehicles. NHTSA is also conducting research on how best to extend this approach to the rest of the FMVSSs not covered in this document and is also conducting research on how the agency might test and evaluate the performance of ADSs. Additionally, NHTSA plans to issue a notice discussing potential safety principles that the agency could assess and validate the competence and safety of ADSs.
23 
A wide array of stakeholders 
expressed support in their comments for treating FMVSS modification differently 
for ADS-equipped vehicles designed to carry human occupants and ADS- equipped vehicles not designed to carry human occupants. For example, the Advocates questioned the need for occupant protection requirements for vehicles that will never carry occupants, while stressing that it believes all other FMVSS requirements (e.g., crash 
avoidance and post-crash survivability, both of which are outside the scope of this NPRM) should be retained to protect all road users.
24The Alliance of 
Automobile Manufacturers (Alliance) stated there may be a need to evaluate provisions of the FMVSS that could have implications for occupant-less ADS-equipped vehicles.
25 
There also seemed to be agreement 
among most stakeholders that maintaining the current level of protection and performance offered by the 200 Series FMVSSs is an important goal in order to ensure the safety of all occupants. Many manufacturers commented that ADS-equipped vehicles that have conventional front row seating configurations and lack manual controls should have the same requirements and protections in all front seating positions. General Motors suggested that NHTSA complete this in the agency’s initial efforts to remove barriers,
26and Waymo 
specifically recommended that NHTSA take the protections of the front right outboard passenger seat and apply those to front left outboard seating position (or what is considered a driver’s seat in a vehicle with manual controls).
27 
Some commenters commented 
extensively on the terms ‘‘driver’’ and ‘‘driver’s seating position.’’ Global Automakers stated that ‘‘these references, as well as other driver reference type categories identified in the Volpe report, should be considered on a case-by-case basis for their potential impact on the ability to certify a vehicle consistent with Federal Standards.’’
28They also stated that it 
may be appropriate for some FMVSSs to require, for instance, that ‘‘driver’s seat’’ requirements apply to any front seating position occupant. Even so, Global Automakers commented that NHTSA should likely use a finite number of alternatives to address references to ‘‘driver’’ throughout the FMVSSs. Zoox Inc. (‘‘Zoox’’) also addressed the modification of the definition of ‘‘driver’’ and provided sample regulatory text in its comments.
29The 
definition of ‘‘human driver’’ that Zoox suggested is the current definition of ‘‘driver’’ found in 49 CFR 571.3. Zoox suggested defining ‘‘human driver’’ and suggested modifying the current definition of ‘‘driver’’ to clarify its applicability to both humans and ADS. Zoox opined that it may also:

number of defined alternatives to addressing 
instances where the term ‘driver’s seat’ appears. For example, in some instances it may be appropriate to redefine the ‘driver’s seat’ as the ‘primary seating position as designated by the manufacturer.’ For other regulations, an alternative could be to define the driver’s seat as the ‘front left-most seat.’ One example of why this is important would be for standards concerning how a dummy may be positioned within the vehicle for the purposes of evaluating compliance with crashworthiness standards.
30 
Some commenters provided detailed 
analysis of the particular barrier that 
they believe each standard poses, including the categorization and nature of the potential barrier. A summary of the discussion for particular standards is listed below by standard. 
—FMVSS No. 201; Occupant 
protection in interior impact. 
Many commenters agreed that FMVSS 
No. 201 would need clarification in order to remove barriers to ADS vehicles. Both the Alliance
31and 
Ford32separated each FMVSS and Part 
Regulation into categories that described the extent and effect of the barrier, as they perceived them. Alliance and Ford both stated that FMVSS No. 201 contained language that did not fully contemplate ADSs, but included barriers that could be resolved with near-term solutions, such as language modifications, interpretations, and exemptions. Motor & Equipment Manufacturers Association commented that FMVSS No. 201 either was not applicable to ADSs or posed a barrier to these vehicles.
33 
After a detailed review of our current 
standards, and in consideration of additional input received through the VTTI research program, NHTSA tentatively agrees with the assessment that the barriers posed by FMVSS No. 201 can and should be relatively easily resolved through language and definitional modifications. Thus, NHTSA proposes to modify the regulatory text of FMVSS No. 201, described in greater detail in later sections of this document. 
—FMVSS No. 203; Impact protection 
for the driver from the steering control system. The Alliance, Ford, and Mercedes 
Benz USA LLC
34stated that FMVSS No. 
203 is likely not relevant or applicable to ADS-equipped vehicles without conventional manual driver controls because the absence of the controls make the regulation unnecessary. Zoox requested regulatory text revisions that would clearly indicate that this standard does not apply to ADS-equipped vehicles without controls. 
After a detailed review of our current 
standards, and in consideration of additional input received through the VTTI research program, NHTSA tentatively agrees with the assessment that the FMVSS No. 203 should not apply to vehicles without steering control systems. However, factors considered go beyond the mere absence of a steering control. The agency describes in greater detail in later sections of this document the justification for this proposed decision. Thus, NHTSA proposes to modify the regulatory text of FMVSS No. 203 to clarify applicability to ADS-equipped vehicles, described in greater detail in later sections of this document. 
—FMVSS No. 204; Steering control 
rearward displacement. 
The Alliance, Ford, and Mercedes 
Benz stated that FMVSS No. 204 is likely not relevant or applicable to ADS- equipped vehicles without conventional manual driver controls because the absence of the controls make the regulation unnecessary. Zoox requested regulatory text revisions that would clearly indicate that this standard does not apply to ADS-equipped vehicles.

Thus, NHTSA proposes modifications to the regulatory text of FMVSS No. 204 to clarify applicability to ADS-equipped vehicles, described in greater detail in later sections of this document. 
—FMVSS No. 205, Glazing materials. 
The Alliance stated that the 
transparency related portions of FMVSS 
No. 205 are likely not relevant or applicable to ADS-equipped vehicles without conventional manual driver controls because the absence of the controls make the regulation unnecessary. Similarly, Ford’s commented that ‘‘this regulation is not applicable’’ to ADS-equipped vehicles with ‘‘sophisticated sensor systems allowing the ADS to see objects surrounding the vehicle.’’
35However, 
the Alliance stated the crashworthiness aspects should be preserved. 
After a detailed review of our current 
standards, and in consideration of additional input received through the VTTI research program, NHTSA tentatively concludes that FMVSS No. 205 remains relevant for crashworthiness of ADS-equipped vehicles without driving controls vehicles. However, NHTSA proposes modifications to the regulatory text of FMVSS No. 205 to clarify applicability only to vehicles that carry occupants, described in greater detail in later sections of this notice. 
—FMVSS No. 206; Door locks and 
door retention components. 
Alliance and Ford both stated that 
FMVSS No. 206 exhibited language that did not fully contemplate ADSs, but included barriers that could be resolved with near-term solutions, such as language modifications, interpretations, and exemptions. The Alliance also specifically mentions the visual or audible warnings that must be conveyed to the driver. 
After a detailed review of our current 
standards, and in consideration of additional input received through the VTTI research program, NHTSA tentatively agrees with the assessment that the barriers posed by FMVSS No. 206 can and should be resolved through language and definitional modifications. Thus, NHTSA proposes modifications to the regulatory text of FMVSS No. 206 described in greater detail in later sections of this notice. However, as noted above, this document does not address issues pertaining to warning systems. 
—FMVSS No. 207; Seating systems. 
While the Alliance stated that it 
believes that FMVSS No. 207 exhibited 
language that did not fully contemplate ADSs, but that the issues could be resolved with minor modifications, Ford indicated that they believed an existing interpretation had resolved the barrier. Zoox requested a modification of the regulatory test to ensure the driver’s seat requirement was clarified as applying to a human.

public with some clarity or additional

its standards as applied to a particular set of facts, modification of regulatory text through notice and comment rulemaking is the appropriate means of making policy changes. After a detailed review of our current standards, and in consideration of additional input received through the VTTI research program, NHTSA tentatively agrees with the assessment that the barriers posed by FMVSS No. 207 can and should be resolved through language and definitional modifications. The agency is using an approach in line with that suggested by the commenters to address the requirement for a driver’s seat. Thus, this proposal provides modifications to the regulatory text of FMVSS No. 207 and its rationale for doing so, which are described in greater detail in later sections of this notice. 
—FMVSS No. 208; Occupant crash 
protection. 
Alliance and Ford both stated that 
FMVSS No. 208 exhibited language that did not fully contemplate ADSs, but included barriers that could be resolved with near-term solutions, such as language modifications, interpretations, and exemptions. 
Additionally, other commenters 
discussed the air bag readiness indicator and advanced air bag suppression status requirements in FMVSS No. 208. Zoox suggested the agency modify the text of FMVSS No. 208 requiring an air bag readiness indicator in S4.5.2 of FMVSS No. 208 to indicate that if there is no driver’s designated seating position, the telltale must be visible to ‘‘at least one designated seating position.’’
36Zoox 
also suggested modified regulatory text for S19.2.2 of FMVSS No. 208, which provides telltale requirements for the advanced air bag suppression status. Zoox suggested that any reference to the ‘‘right’’ front passenger be changed to the ‘‘outboard’’ front passenger and thus allowing for the possibility of there being a telltale for any front outboard location.
37 
After a detailed review of our current 
standards, and in consideration of additional input received through the VTTI research program, NHTSA tentatively agrees in part with the assessment that many of the barriers 
posed by FMVSS No. 208 can and should be resolved through language and definitional modifications, and thus, has included this standard in this NPRM. The agency notes that other barriers, such as those involving 
indicator and warnings included in FMVSS No. 208 may be addressed in a future notice that includes a holistic discussion of the appropriate applicability of telltale requirements in ADS-equipped vehicles. 
—FMVSS No. 214; Side impact 
protection. 
While the Alliance stated that it 
believes that FMVSS No. 214 exhibited language that did not fully contemplate ADSs, but that the issues could be resolved with minor modifications, Ford indicated that they believed an existing interpretation had resolved the barrier. 
While an interpretation provides the 
public with some clarity or additional insight into NHTSA’s interpretation of its standards as applied to a particular

—FMVSS No. 216a; Roof crush 
resistance; Upgraded standard. 
While the Alliance stated that it 
believes that FMVSS No. 216a exhibited language that did not fully contemplate ADSs, but that the issues could be resolved with minor modifications, Ford indicated that they believed an existing interpretation had resolved the barrier.

—FMVSS No. 225; Child restraint 
anchorage systems.

believes that FMVSS No. 225 exhibited language that did not fully contemplate ADSs, but that the issues could be resolved with minor modifications, Ford indicated that they believed an existing interpretation had resolved the barrier. After a detailed review of our current 
standards, and in consideration of additional input received through the VTTI research program, NHTSA tentatively agrees with the assessment that the barriers posed by FMVSS No. 225 can and should be resolved through language and definitional modifications, and thus, has included this standard in this NPRM. Thus, NHTSA proposes modifications to the regulatory text of FMVSS No. 225, described in greater detail in later sections of this notice. 
—FMVSS No. 226; Ejection 
Mitigation. 
Alliance and Ford both stated that 
FMVSS No. 226 exhibited language that did not fully contemplate ADSs, but included barriers that could be resolved with near-term solutions, such as language modifications, interpretations, and exemptions. 
After a detailed review of our current 
standards, and in consideration of additional input received through the VTTI research program, NHTSA tentatively agrees in part with the assessment that many of the barriers posed by FMVSS No. 226 can and should be resolved through language and definitional modifications, and thus, proposes modifications to this standard in this NPRM. The agency notes that other barriers, such as those involving the ejection mitigation countermeasure indicator included in FMVSS No. 226, would be more appropriately addressed in the agency’s planned future notice relating to the appropriate applicability of telltale requirements in ADS-equipped vehicles. 
III. Limitations on Scope and Guiding 
Principles for Initial Identification and Removal of Regulatory Barriers 
The changes proposed in this NPRM 
seek to remove unnecessary regulatory barriers to ADS-equipped vehicles in the crashworthiness FMVSSs, while maintaining the level of occupant protection that these standards currently provide. Additionally, the proposed changes would clarify the application of the crashworthiness standards to ADS- equipped vehicles without traditional manual controls, and would make changes facilitating certification and compliance verification of these vehicles to occupant protection requirements. NHTSA believes that, if adopted, the proposed changes would provide regulatory certainty for vehicle manufacturers as to whether and how to certify the compliance of ADS-equipped vehicles without manual controls to the 200 Series FMVSSs, and would reduce the number of requirements from which manufacturers of these vehicles may

38The agency has also analyzed the 300 Series 
standards, but no changes are being proposed in 
this notice. 
39The agency notes that vehicles equipped with 
an ADS that have traditional manual controls are currently covered by the occupant protection FMVSS and can typically be certified as such. However, NHTSA acknowledges that there may be some regulatory uncertainty on the part of manufacturers related to the 200 Series FMVSSs, even for ADSs with manual driving controls, which this NPRM seeks to address through proposed modifications of the existing regulatory requirements and definitions.

41Although conventional forward-facing seats are 
assumed, the proposal does not assume that every vehicle has front outboard seats as currently defined. 42See Contract No. DTNH2214D00328L/

4449 CFR 571.3. need to seek a temporary 
exemption.38 39 
In developing this NPRM, the agency 
limited the scope of the barriers addressed by this proposed rule to exclude certain subject matters which the agency intends to address in other notices. NHTSA also followed certain guiding principles to ensure that the proposed changes properly balanced the interests of safety, feasibility and transparency with the public. We explain these scope limitations and guiding principles in greater detail below. 
a. Limitations on Scope 
Although this document is the 
agency’s first proposal containing 
modified regulatory text for the accommodation of ADS-equipped vehicles without traditional manual controls, NHTSA has other notices with similar goals planned.
40As such, this 
proposal is limited in scope and rests on a number of assumptions, which are described in this section. First, we assume that the initial ADS-equipped vehicles will have seating configurations similar to non-ADS vehicles, i.e., forward facing front 
seating positions (conventional seating). This approach of addressing conventional seating first is consistent with many of the comments provided in response to the RFC.
41This limitation is 
primarily relevant to crashworthiness standards with dynamic crash test performance requirements for occupants, i.e., FMVSS Nos. 201, 
‘‘Occupant protection in interior impact,’’ 208, ‘‘Occupant crash 
protection,’’ and 214, ‘‘Side impact protection.’’ The narrow scope of this document should in no way be interpreted that the agency believes that these standards are limited in applicability to ADS-equipped vehicles with conventional seating or that future updates will not be necessary to allow for ADS-equipped vehicles with unconventional seating arrangements. Nonetheless, we have not attempted to address in this document the revisions that may be necessary to provide regulatory certainty for manufacturers that wish to self-certify ADS-equipped vehicles with unconventional seating arrangements. Modifying current standards to account for and include non-traditional seating configurations requires significant additional research that the agency recently began. This research has been informed through input from the VTTI project
42and the 
RFC, as well as and continues to be informed through public outreach on the agency’s research portfolio.
43 
Second, this NPRM addresses the 
topic of ADS vehicles designed exclusively to carry property (‘‘occupant-less vehicles’’) to the extent that the agency proposes that current crashworthiness requirements intended to protect human occupants should not apply to such vehicles. Our preliminary analysis leads us to conclude that occupant-less vehicles meet the Part 571.3 definition of a truck because occupant-less vehicles have no designated seating positions (DSPs), which necessarily means they are ‘‘designed primarily for the transportation of property.’’
44However, 
the agency solicits feedback on other perspectives from commenters. For occupant protection requirements tied to a particular DSP location, the absence of a DSP in a vehicle means that the associated performance test cannot be conducted. More detail is provided in the sections of this NPRM where we explain the changes made to each standard. 
Notwithstanding this added 
clarification, NHTSA wishes to acknowledge that potential entrance of occupant-less vehicles into the market could theoretically have downstream effects on vehicle safety. The frontal crash protections provided for vehicle occupants by FMVSS No. 208 promotes vehicle structures that reduce the crash forces felt not only by occupants, but also by occupants of collision partners. These associated effects could be offset in whole or in part by the design and size of the vehicles. This is a complex issue and we are not prepared to address this topic further at this time. NHTSA plans to complete research and separately seek public comment on the creation of a new FMVSS category for occupant-less vehicles. 
Further, another limitation on the 
scope of this document relates to the barriers present in the standards within this document related to telltales and warnings. The agency is not prepared at this time to provide a thorough analysis with respect to the topic of telltales and warnings as they related to ADS- equipped vehicles, including where there is no requirement for any occupant to be seated in what is currently considered the driver’s designated seating position (driver’s seat). This is a broad topic found throughout many of the FMVSS, not just the 200 Series standards. As mentioned above, research is continuing in this area, and the agency plans to publish a separate notice related to telltales. However, the availability of the telltale related to the suppression of frontal passenger air bags is the one excepted area that will be discussed in this document (see section VI.a.5, below). 
In analyzing the current 200 Series 
regulatory text and developing the necessary revisions, there were certain overarching principles NHTSA attempted to keep in the forefront and guide the process. Below the agency describes the principles that guided our consideration of how best to apply the current FMVSSs to ADS-equipped vehicles. 
b. Guiding Principles to NHTSA’s 
Approach in Updating the Crashworthiness FMVSS to Account for ADSs 
1. Maintain Current Performance 
Requirements 
NHTSA took every effort to maintain 
the level of crashworthiness performance in ADS-equipped vehicles without traditional manual controls currently required for vehicles without ADS functionality with the goal of maintaining occupant protection. In addition, the agency has attempted to craft the proposal such that it will have no effect on vehicles without ADS functionality. In doing so, NHTSA examined both the safety intent and specific performance requirements of the current standards as they apply to non-ADS vehicles. Although the safety intent may in certain cases appear to be somewhat abstract, they come more

46In this notice, this means a vehicle that has 
controls for human driving as well as a mode for 
ADS driving, whether or not the human driving controls are position for use. clearly into focus when specific 
requirements and regulatory text sections, such as purpose, scope, application, and definitions, are analyzed. 
In consideration of the above, one of 
the complicating factors that became apparent was that a literal translation of the current regulatory text may in some cases be insufficient to maintain the safety intent or the existing level of performance. Nonetheless, the agency recognizes that there can be multiple valid approaches to achieving this goal of maintaining the performance requirements and that there can be reasonable disagreements about the safety intent and equivalence of safety when dealing with requirements that were, in some cases, promulgated many years ago. 
2. Reduce Unnecessary Regulatory 
Barriers and Uncertainty for Manufacturers 
We seek to modify the existing 
FMVSSs in a way that will help provide regulatory certainty for manufacturers developing ADS-equipped vehicles and reduce unnecessary certification barriers and cost in certain areas. If done correctly, this should help streamline manufacturers’ certification processes, reduce certification costs and minimize the need for future NHTSA interpretation or exemption requests. Likewise, this approach will help the agency become more effective and efficient in the focused treatment of the fewer and more complex application of existing standards. NHTSA proposes to accomplish this in a way that maximizes stakeholder input and transparency and will garner public trust in the regulatory process for ADS vehicles. 
3. Maintain the Current Regulatory Text 
Structure 
The changes proposed in this 
document are intended to adapt existing FMVSS requirements for ADS vehicles in a way that does not change the existing requirements for non-ADS vehicles (i.e., vehicles with a driver’s 
DSP). In some cases, this makes the new regulatory text more complex than it would otherwise need to be if this bifurcation were not made. In some instances, it may be possible to use the new translation specific to ADS vehicles and apply it to all vehicles, without any substantive change for non-ADS vehicles. We ask commenters to indicate where they believe this might be the case. We will attempt to highlight some of those situations, where appropriate in this notice. 4. Remain Technology Neutral 
One of the core tenets of NHTSA’s 
recent work to modernize the FMVSSs 
is to do so in a manner that becomes more inclusive of the unique interior designs that are expected to accompany ADS-equipped vehicles and to instill 
technology neutrality in the regulatory text of the standards, to the extent practicable. This tenet is one of the DOT’s Automation Principles, as described in Preparing for the Future of Transportation: Automated Vehicles 3.0, and is in line with previous DOT 
guidance that advised legislatures throughout the United States to also adopt this principle.
45The agency 
believes that this proposal exemplifies this tenet, while balancing the needs for maintaining occupant protection standards. NHTSA requests comment on whether there are additional changes that the agency could make to be more inclusive of different technologies and improve technology neutrality in the FMVSS. 
IV. Maintaining Original Safety Intent 
and Performance Requirements 
a. Application to Crashworthiness 
Standards 
Other than dual-mode vehicles,
46a 
fundamental feature of many Level 4 and Level 5 ADS-equipped vehicles will likely be the absence of manual driving controls in left front outboard designated seating position, previously occupied by the driver in non-ADS vehicles. Thus, what was previously a driver’s seating position, will effectively become a passenger seating position. We have attempted to maintain the safety intent and level of safety previously available to drivers by applying the same crash test performance requirements as the right front occupant to the left front outboard occupant. This concept was supported by several RFC commenters. This is neither surprising nor novel for crash protection required by the FMVSSs in that currently both front outboard seating positions are subjected to identical crash and impact tests, with the same adult sized test dummies and injury criteria. For example, the crash test requirements only deviate with respect to dummy positioning consistent with driving controls being available in the left front seat. Regulatory text changes are proposed to clarify that the right front 
passenger protection will be mirrored on the left side. 
However, there are some unique 
aspects of occupant protection related to advanced air bags that differ from passenger to driver seat. The right front outboard seating position (current passenger position) is subjected to a suite of tests designed to determine if the air bag will suppress or deploy in a low risk manner for out-of-position (OOP) occupants. The driver’s seating position also has performance requirements for an OOP driver. As is the case for crash protection, if the left front outboard occupant becomes a passenger due to the elimination of driving controls, NHTSA believes that position would need to have the same OOP protection offered to the right front occupant. Regulatory text changes are proposed to clarify that the right front passenger OOP protection will be mirrored on the left side. 
Finally, as the agency works toward 
providing regulatory certainty in the self-certification process while maintaining current safety levels, it has become clear that the current vehicle occupancy patterns may change for ADS vehicles. NHTSA is aware that existing occupant crash protection has been biased towards front outboard seat occupants, because traditionally, every vehicle has a driver and the right front passenger seat is the next most frequently occupied. This may not be the case for ADS vehicles, even with conventional forward-facing seats, thus likely changing the overall injury patterns seen in the vehicle fleet. As technology develops and ADS-equipped vehicles become more prevalent, this could necessitate a reassessment of the crash protection offered to occupants other than those in the front seats. This 
document does not attempt such a task. 
V. New and Current Definitions in Part 
571.3 
One of the primary challenges to the 
self-certification of ADS-equipped vehicles without traditional manual controls is the pervasive use of some form of the term ‘‘driver’’ throughout the FMVSSs. Although the terms ‘‘driver,’’ ‘‘driver’s’’ and ‘‘driving,’’ appear upwards of 200 times throughout the FMVSSs, each instance it is used falls roughly into one of four categories. Specifically, a driver is: (1) An entity that performs certain actions necessary for the determination of FMVSS compliance, e.g., brake pedal 
application in FMVSS No. 135, ‘‘Light vehicle brake system;’’ (2) a vehicle occupant who must be protected in a crash, e.g., frontal crash protection in

48The terminology being used in this document 
is Autonomous Driving System (ADS). 49Incorporates the definition of ‘‘driver’s 
designated seating position.’’ 
50Incorporates the definition of ‘‘driver’s 
designated seating position.’’ 
51Incorporates the definition of ‘‘manually- 
operated driving controls.’’ FMVSS No. 208; (3) a spatial frame of 
reference for vehicle geometry, e.g., vehicle attitude in FMVSS No. 216a, and (4) an entity that receives messaging from the vehicle, e.g., door opening 
warning in FMVSS No. 206. All of these characteristics of a vehicle that relate to the driver terms must be considered when attempting to apply the current FMVSSs to vehicles equipped with ADS and when attempting to provide a holistic solution to the challenges in updating the FMVSSs to reflect the changed circumstances that ADS- equipped vehicles without manual controls will present. 
By way of background, for more than 
50 years the term ‘‘driver’’ has been defined in Part 571.3 as ‘‘the occupant of a motor vehicle seated immediately behind the steering control system.’’ The plain meaning of the term ‘‘occupant’’ is a human, since a human occupies space in the vehicle and would be seated in a designated seating position. Moreover, if the term ‘‘occupant’’ is understood to mean a human occupant, this definition is compatible with the four characteristics of a driver mentioned above. 
While limiting the term ‘‘driver’’ to a 
human is consistent with the plain meaning of the ‘‘driver’’ definition, and is compatible with the current uses of the term ‘‘driver’’ in the FMVSS, it also precludes use of an unmodified version of the term to describe the driving functionality of the ADS. In recognition of the potential regulatory challenges that NHTSA’s longstanding definition of the term ‘‘driver’’ could create for manufacturers of these ADS-equipped vehicles, NHTSA issued an interpretation letter to Google in 2016 (the ‘‘Google Interpretation’’) in which the agency explained how it would adapt the definition of driver to the extent possible to account for ADS- equipped vehicles.
47In this 
interpretation, the agency explained that it would interpret the definition of driver as follows: 
‘‘NHTSA will interpret ‘driver’ in the 
context of Google’s described motor vehicle 
design as referring to the SDS [Self-Driving System],
48and not to any of the vehicle 
occupants. . . . If no human occupant of the vehicle can actually drive the vehicle, it is 
more reasonable to identify the ‘driver’ as whatever (as opposed to whoever) is doing the driving.’’ However, NHTSA also explained that 
the agency would consider initiating 
rulemaking to determine whether the definition of ‘‘driver’’ in Part 571.3 should be updated in response to changing circumstances. 
We note that the current ‘‘driver’’ 
definition is inextricably linked to the ‘‘steering control system,’’ which is defined in FMVSS No. 203, ‘‘Impact protection for the driver from the steering control system,’’ as ‘‘the basic steering mechanism and its associated trim hardware, including any portion of a steering column assembly that provides energy absorption upon impact.’’ Although this definition also presents regulatory challenges for ADS- equipped vehicles, the Google Interpretation did not address how NHTSA would interpret this term. 
a. Approach to Driver Definition for 
This NPRM 
The agency has tentatively decided 
that it will not revise the regulatory definition of ‘‘driver’’ found in 49 CFR 571.3 at this time. Instead, NHTSA proposes to maintain the current definition without change, but to augment this definition with other supporting or clarifying definitions to indicate when the FMVSS is referring to a human driver or an ADS for the purposes of this document and for clarifying the crashworthiness FMVSSs. 
NHTSA has decided not to modify the 
regulatory definition of driver in this document for these primary reasons: 
•The agency should consider holistically 
whether to and how best to update the term 
‘‘driver’’ in 571.3, and doing so in a notice focused solely on the crashworthiness FMVSSs could cause issues with future FMVSS updates that they agency has planned. Such future updates may necessitate revisiting the 200 Series standards. 
•The agency believes that updating the 
term ‘‘driver’’ is not ripe at this time and unnecessary due to the limited types of usage throughout the crashworthiness FMVSS and the potential complications making changes could cause for the crash avoidance FMVSS and standards that refer to telltales, warnings, and alerts. 
•The agency should consider, if updating 
the term ‘‘driver’’, whether and how best to include a definition of the ADS in the regulatory text, which the agency expects would be a very complex process due to the types of references to ‘‘driver’’ in the FMVSS and the frequent terminology changes referencing ADS-equipped vehicles that the agency has witnessed over the past several years. 
•This approach is consistent with input 
the agency received through the VTTI research program, which included feedback from expert researchers, industry stakeholders, and advocates. While NHTSA has decided not to 
modify the definition of ‘‘driver’’ with 
this notice, it is considering doing so for future notices. Thus, the agency requests comment on various approaches that could be utilized in a holistic manner (i.e., are there 
definitions the agency should consider that would properly cover the four types of uses of ‘‘driver’’ and derivatives of ‘‘driver’’ throughout the FMVSS). As noted above, NHTSA acknowledges that it may in the future be necessary for the agency to create new defined terms within the FMVSS such as ‘‘ADS’’ to clarify when the regulatory text is referring to a non-human entity controlling the vehicle. However, as this is not needed in the context of the changes that NHTSA is proposing in this document to make to the crashworthiness standards (which focus almost exclusively on the protection of humans), no such definition is proposed in this notice. 
b. New, Modified and Relocated 
Definitions 
While this NPRM does not propose 
changing the term ‘‘driver’’ itself or adding definitions of ‘‘ADS,’’ it does propose creating supplemental definitions of terms already used and amending driver-related definitions that exist in the current FMVSS. By defining or amending these terms, NHTSA hopes to clarify the application of crashworthiness FMVSS to ADS- equipped vehicles with minimal disruption to the existing regulatory text. The specific terms that exist in the FMVSS that the agency is proposing to define are ‘‘driver dummy,’’ ‘‘driver air bag,’’ ‘‘driver’s designated seating position,’’ and ‘‘passenger seating position.’’ Our proposed definitions of these terms are shown below. 
Driver air bag means the air bag 
installed for the protection of the occupant of the driver’s designated seating position.
49 
Driver dummy means the test dummy 
positioned in the driver’s designated seating position.
50 
Driver’s designated seating position 
means a designated seating position providing immediate access to manually-operated driving controls.
51 
As used in this part, the terms ‘‘driver’s seating position’’ and ‘‘driver’s seat’’ shall have the same meaning as ‘‘driver’s designated seating position.’’ 
VerDate Sep<11>2014 18:23 Mar 27, 2020 Jkt 250001 PO 00000 Frm 00011 Fmt 4701 Sfmt 4702 E:\FR\FM\30MRP2.SGM 30MRP2lotter on DSKBCFDHB2PROD with PROPOSALS217634 Federal Register / Vol. 85, No. 61 / Monday, March 30, 2020 / Proposed Rules 
52We note that this means, in ADS–DV that has 
non-stowable manually-operated controls at a given 
seating position, NHTSA would consider that seating position to be a ‘‘driver’s designated seating position’’ regardless of whether or not the ADS is driving the vehicle for the purposes of the crashworthiness standards. 53In addition, we have determined that no change 
is need for FMVSS Nos. 301, 302, 303, and 304. Any changes to FMVSS No. 305 will be discussed in future notices. Passenger seating position means any 
designated seating position other than 
the driver’s designated seating position. As used in this part, the term ‘‘passenger seat’’ shall have the same meaning as ‘‘passenger seating position.’’ As used in this part, ‘‘passenger seating position’’ means a driver’s designated seating position with stowed manual controls. 
NHTSA is also proposing to add the 
new term ‘‘manually-operated driving controls’’ which is not a term currently used in the FMVSS. NHTSA’s proposed definition is shown below. 
Manually-operated driving controls 
means a system of controls: 
(1) That are used by an occupant for 
real-time, sustained, manual manipulation of the motor vehicle’s heading (steering) and/or speed (accelerator and brake); and 
(2) That are positioned such that they 
can be used by an occupant, regardless of whether the occupant is actively using the system to manipulate the vehicle’s motion. 
In subpart (2) the definition states that 
the controls must be positioned for use by the occupant, whether or not the occupant is actively manipulating them. This means that, if manually operated driving controls are in place in front of a given seating position, the occupant of that seating position is considered a ‘‘driver’’ for purposes of the FMVSS— regardless of whether an ADS is controlling the vehicle. In such a case, the seat would be considered a ‘‘driver’s designated seating position’’ under the FMVSS.
52Conversely, if controls are 
not present in front of a seating position, either because they are stowed or because the vehicle is not equipped with manually-operated driving controls, the occupant in that seating position is not a ‘‘driver.’’ In this case, the seating position would be considered a ‘‘passenger seating position’’ under the FMVSS. If dual- mode vehicles have the capability of stowing driving controls, NHTSA expects that manufacturers will need to certify compliance in both states (e.g., manually-operated driving controls available and stowed). 
Another proposed modified definition 
that would reference the new definition of ‘‘manually-operated driving controls’’ is the term ‘‘steering control system,’’ which is provided below. Steering control system means the 
manually-operated driving control(s) 
used to control the vehicle heading and its associated trim hardware, including any portion of a steering column assembly that provides energy absorption upon impact. As used in this part, the term ‘‘steering wheel’’ and ‘‘steering control’’ shall have the same meaning as ‘‘steering control system.’’ 
The modification proposed here 
would modify the existing definition of ‘‘steering control system,’’ in FMVSS No. 203 to incorporate the proposed definition for ‘‘manually-operated driving controls.’’ We also propose relocating this definition to Part 571.3, and applying it to the terms ‘‘steering wheel’’ and ‘‘steering control,’’ which are not currently defined. However, we have tentatively determined these variations have the same meaning when used in the FMVSSs. Since these terms appear throughout the FMVSSs, specifying the definition for ‘‘steering control system’’ would clarify their meaning with respect to ADS and non- ADS vehicles with minimal disruption to the existing regulatory text. 
NHTSA also proposes to clarify that 
the terms ‘‘outboard seating position’’ and ‘‘outboard seat’’ have the same meaning as used in the existing definition of ‘‘outboard designated seating position.’’ From our analysis of the regulatory text of the crashworthiness FMVSSs, we have tentatively determined these three terms have the same meaning. Therefore, to clarify this point, we have added language specifying that ‘‘outboard seating position’’ and ‘‘outboard seat’’ 
have the same meaning as ‘‘outboard designated seating position.’’ 
Finally, we are proposing to relocate 
the definition of ‘‘row,’’ which is currently located in FMVSS No. 226, to Part 571.3. We have proposed the use of this term in multiple standards (FMVSS Nos. 201, 206 and 208). Moving it to Part 571.3 will eliminate the need to insert a reference to its current location. 
We are proposing that each of these 
new and modified definitions be added 
or moved to Part 571.3, and that they be applicable to every FMVSS in the interest of efficiency and consistency. Another option that the agency recognizes as a potential solution is to place the relevant definitions within each standard that utilized the defined term in order to avoid creating additional confusion or conflict in other FMVSSs, such as the crash avoidance standards (100 Series FMVSS). While these changes may not resolve the barriers in the crash avoidance FMVSSs, the agency intends to address those issues and others in future notices. This would be necessary if one or another of the definitions would create a conflict within some standard and the conflict could not be resolved in another way. 
We seek comment on our proposals 
for new, modified, and relocated definitions, as well as the general approach and options described in this section. We also seek comment on whether the changes proposed in this section would create any definitional conflicts within the FMVSSs, such as causing additional, unintended confusion for manufacturers certifying to other FMVSSs not covered by this notice. 
VI. Changes to the Regulatory Text of 
the Affected Standards 
This section describes and explains 
the changes being proposed to the regulatory text of the affected standards. We have tentatively determined that no change is needed for FMVSS Nos. 202a, 209, 210, 212, 213, 217, 218, 219, 220, 221 and 222.
53Rather than explaining 
each proposed change individually, which would be both cumbersome and repetitive, the agency has identified several categories of changes based on the substance of the change and its underlying justification. Because generic descriptions of the categories of changes may be difficult to grasp in the abstract, NHTSA explains each category of change using illustrative examples from the affected standards in the sections that follow. 
Each subsection below covers the 
changes made to an individual crashworthiness standard affected by this proposal. In each subsection, we identify which category(ies) of changes we are proposing to the regulatory text of that standard, along with citations to the specific provisions that would be amended. The first time a category of change to the regulatory text is discussed, we provide a full and detailed description of what is being changed, and our reason for the change. When a category of change to the regulatory text appears again in subsequent standards, we cross reference back to the subsection in which the change category is described and explained. In addition, in certain instances where we have deemed appropriate, explanations are provided for why we do not believe a change to the regulatory text is needed. 
The subsections are organized 
sequentially by standard number, except that the first standard addressed is

54NHTSA acknowledges that the future 
implementation of occupant-less vehicles may be 
on vehicle platforms which do not appear to be what many would consider a ‘‘truck.’’ Nonetheless, 
the current definitions of ‘‘truck’’ in 571.3 is the only vehicle type definition, (i.e., bus, multipurpose 
passenger vehicle, passenger car, and truck), that specifically covers vehicles designed to carry property and not ‘‘persons.’’ In response to requests from stakeholders, the agency is evaluating whether a new vehicle class may be necessary for certain delivery vehicles, including occupant-less ones. 
55We note that there are some standards that are 
applicable to trucks that we have chosen not to specify that they only apply if a DSP is present because the standard is clearly only applicable to DSP location. One such example is FMVSS No. 202a. This clarification with respect to trucks is consistent with past agency practice in that, except for trucks, the application sections of the crashworthiness standards specify vehicle types that carry people. In addition, we believe that all current crashworthiness standards are specifically intended for the protection of occupants within the vehicle to which they apply. 
56An exception to this would be if an outboard 
seat is eliminated, as is discussed in section VI.a.3. 
57Part 571.4 provides that ‘‘[t]he word any, used 
in connection with . . . a set of items in a 
requirement . . . means generally the totality of items . . . any one of which may be selected by the Administration for testing.’’ FMVSS No. 208. We decided to analyze 
FMVSS No. 208 first for the sake of clarity, since it has the greatest number and greatest variety of proposed changes to its text. The explanations below include tables comparing the original regulatory text with the proposed regulatory text to provide illustrative examples of each change category. In addition, to illustrate the precise changes that are being proposed within the context of the full regulatory text, we are providing in the docket for this rulemaking an appendix document that contains the full proposed regulatory text of each modified standard, with added text in blue underlined font and the deleted text in red strikethrough font. The proposed regulatory text modifications are provided in the end of this NPRM. 
a. FMVSS No. 208; ‘‘Occupant Crash 
Protection’’ 
The purpose of FMVSS No. 208, 
Occupant crash protection, is to reduce the number of deaths and injuries to vehicle occupants in the event of a crash. To this end, FMVSS No. 208 specifies types and locations of seat belts and frontal air bags as well as crashworthiness requirements in terms of forces and accelerations on anthropomorphic dummies in test crashes. In specifying these crashworthiness requirements, FMVSS No. 208 assumes the presence of, and refers to, the driver’s seating position and steering control. These assumptions make certification and compliance verification of ADS-equipped vehicles without these components difficult or impossible. 
Below we identify the specific 
provisions of FMVSS No. 208 that we believe are potential barriers to the certification and compliance verification of an ADS-equipped vehicle, and we explain how we propose to revise those provisions to maintain the same level of performance currently required by the standard. 
1. Application to Vehicles Without 
Designated Seating Positions 
Currently, FMVSS No. 208 applies to 
all passenger cars, multipurpose passenger vehicles (MPVs), trucks, and buses. While most of these vehicle types carry ‘‘persons,’’ by definition, trucks do not. This means that because FMVSS No. 208 applies to all trucks, the standard would also apply to occupant- less trucks that have no designated seating positions (DSPs).
54This creates a barrier to certification because the 
requirements of FMVSS No. 208 are linked to the existence of specified DSPs. For example, the advanced air bag crash test requirements are applied to the front outboard DSPs by virtue of S5.1.1 through S14. 
Because occupant-less trucks would 
presumably have no DSPs, it is unclear how the test could be performed. NHTSA tentatively concludes that the safety need that supports the crashworthiness requirement of FMVSS No. 208 for the protection of vehicle occupants does not exist for occupant- less trucks. Accordingly, NHTSA is proposing to amend the application section of FMVSS No. 208 to apply only to trucks with DSPs.
55Accordingly, we 
are proposing to modify S3. Application to specify that the standard applies to trucks only if they have at least one DSP, as shown below in Table VI–1. No other changes are proposed for the Application Section. 
TABLE VI–1 
Before Change 
S3. Application. (a) This standard applies to 
passenger cars, multipurpose passenger 
vehicles, trucks, and buses. 
After Change 
S3. Application. (a) This standard applies to 
passenger cars, multipurpose passenger vehicles, trucks with at least one des-ignated seating position, and buses. 
We request comment on our proposed 
addition to the Application Section, 
changes not made and additional changes commenters believe to be necessary. 2. Textual Modifications Addressing 
That There May Be No Driver’s Seat and Multiple Outboard Passenger Seats 
The agency proposes to treat any seat 
that does not have immediate access to traditional manual controls (what we have defined as ‘‘manually-operated driving controls’’) as a passenger seat. This includes a seat located in the left front outboard position, where the driver’s seat is typically located. NHTSA has tentatively concluded that the most practicable way to maintain occupant protection in ADS-equipped vehicles with no manual controls (and thus, with no driver’s seat) is to require that all front outboard passenger seats meet the crash test performance requirements presently performed on the right front outboard passenger seat. For a passenger seat located in the left front outboard position, this would be done by mirroring the test procedures and requirements from the right side. 
NHTSA believes this approach will 
maintain the level of occupant protection currently offered by compliance with FMVSS No. 208 because it merely extends existing requirements for the front right passenger position to all outboard front passenger positions, regardless of vehicle side, and it would not affect the occupant protection requirements for conventional vehicles. Moreover, this approach would not significantly impact the testing burden on manufacturers, since it simply requires that test labs follow procedures for the passenger dummy on both sides of the vehicle rather than the procedures for the driver and outboard passenger test dummy that would be used for a crash test of a conventional vehicle.
56 
To accomplish this change, we 
propose genericizing all references to ‘‘passenger’’ dummies by replacing the term with ‘‘front outboard passenger’’ dummy. An example of the type of change made is provided below in Table VI–2, from the general positioning of the arms of a crash test dummy. Previously, the passenger dummy was referred to in the singular. Now we are making clear that there may be more than one passenger dummy by the use of the phrase ‘‘any front outboard passenger.’’ The term ‘‘any’’ here is consistent with definition provide in Part 571.4.
57 
Similar changes are made through the standard and are too many to mention.

vehicle weight rating (GVWR) less than 4,536 
kilograms (kg) (10,000 pounds (lb)). 
59Trucks and multipurpose passenger vehicles 
with a GVWR of more than 3,855 kg, but not greater than 4,536 kg, have compliance options involving crash tests, which relieve the requirement of providing Type 2 seat belts.

NHTSA recommends that children not be placed in

3. The Treatment of Outboard Versus 
Center Seating Positions in the Front Row of Light Vehicles 
For most light vehicles,
58each 
outboard designated seating position, 
including the driver’s seat, is required to have ‘‘Type 2’’ (lap and shoulder) seat belt assembly that conforms to FMVSS No. 209.
59Moreover, the subset of light 
vehicles that have a GVWR of less than 3,855 kg (8,500 lb) and unloaded weight of 2,495 kg (5,500 lb) are statutorily required to have frontal air bag protection at the driver’s and right front DSPs.
60 61 Any center seating positions 
in these light vehicles are allowed to be equipped with lap belts. ADS-equipped vehicles without driving controls may not have a front left outboard DSP or for that matter, any outboard DSP. Seating position could be moved toward the center of the vehicle. In this case, conceivably an ADS-equipped vehicle could be constructed with no air bag or lap and shoulder seat belts, although the agency believes this would be highly unlikely. In the regulatory text changes proposed in this notice, the agency has not attempted to address the reduction in frontal crash protection that would occur if previous outboard DSPs in non- ADS vehicles become inboard/center DSPs in ADS-equipped vehicles. We request comment on whether the final rule should require air bag (including OOP protection) and lap/shoulder seat belt protection to these inboard seating positions, if outboard positions are removed. We also seek comment on implications of such designs upon the statutory obligation for frontal air bags. 4. Treatment of Advanced Air Bags 
Under the proposed rule, any front 
outboard seating position that does not have manual controls would be considered a passenger seat, and would need to meet passenger seat occupant protection requirements. Accordingly, in an ADS–DV without manual controls, the front left outboard seating position (i.e., the seating position that would 
typically be the driver’s seat in a traditional vehicle), would need to meet passenger seat requirements. The regulatory requirements pertaining to frontal air bags for both the occupants of the driver’s seat and passenger seat are commonly known as ‘‘advanced air bag’’ requirements. However, unlike a driver’s seat, which must only meet adult occupant protection requirements, a passenger seat must meet both adult and child occupant protection requirements. 
NHTSA seeks comment on whether it 
is necessary to apply passenger (child and adult) advanced air bag requirements to both front outboard seats in an ADS-equipped vehicle without manual controls because both of those seats would be available for child occupants.
62(In a traditional 
vehicle, the occupant in the driver’s seat is all but guaranteed to be an adult, making child advanced air bag protections unnecessary). In practice, this would mean that the advanced air bag protections that traditional vehicles currently provide on the right front outboard seat would be mirrored in the left. NHTSA seeks comment on alternative techniques to ensure children receive existing protection. 
To apply passenger advanced air bag 
requirements to all front outboard seating positions, we have proposed to add the modifier ‘‘any front outboard’’ to the word ‘‘passenger’’ in the relevant sections of S19 through S24, S27 and S28. An example of this is provided below in Table VI–3. 
TABLE VI–3 
Before Change 
S19.2.1 The vehicle shall be equipped with 
an automatic suppression feature for the 
passenger air bag which results in deacti-vation of the air bag during each of the static tests specified in S20.2 ....  TABLE VI–3—Continued 
After Change 
S19.2.1 The vehicle shall be equipped with 
an automatic suppression feature for any front outboard passenger air bag which re-sults in deactivation of the air bag during each of the static tests specified in S20.2 ....  
5. Advanced Air Bag Suppression 
Telltale for Passenger Air Bags 
NHTSA seeks comment on amending 
the activation requirement for the 
advanced air bag suppression telltale required under FMVSS No. 208, S19.2.2 to eliminate references specifying a ‘‘passenger air bag system.’’ NHTSA has tentatively concluded that this change is necessary to permit the certification of ADS-equipped vehicles, which may have more than one passenger seat with an advanced air bag system. We wish to emphasize that, as noted earlier, this NPRM is not intended to address issues relating to telltales and warnings, and the change proposed here is not intended to indicate a policy position regarding the necessity or effectiveness of this or other telltales. 
NHTSA seeks comment on requiring 
each front outboard passenger seat with a suppression-based advanced air bag system to have a unique telltale, so that occupants know which air bag is suppressed. This would maintain the current level of safety provided by the standard because the telltale’s substantive performance criteria would remain the same, providing occupants with the same level of information about the status of each relevant air bag as the current standard. Table VI–4 shows the regulatory text changes related to the number of telltales. We note that S21.2.2 and S23.2.2 refer back to S19.2.2. 
TABLE VI–4 
Before Change 
S19.2.2 The vehicle shall be equipped with 
at least one telltale which emits light when-
ever the passenger air bag system is de-activated and does not emit light whenever the passenger air bag system is activated, except that the telltale(s) need not illu-minate when the passenger seat is unoc-cupied.

6. Treatment of ADS Vehicles With 
Driving Controls When Children Are in the Driver’s Seat 
It is possible that some ADS-equipped 
vehicles will be equipped with manual driving controls and that the vehicle is designed for both driverless operation and operation by a conventional driver for complete trips (i.e., dual-mode). In 
such vehicles, the seat where the manual controls are located would still be a driver’s seat even when the ADS is engaged, and thus would be required to meet driver’s seat occupant protection requirements. However, because such a vehicle could be capable of operation without a driver, it is possible that a child not old enough to drive could be placed in the driver’s designated seating position. NHTSA believes this would be an inherently unsafe condition, particularly for smaller children, because the driver’s seating position is not required to have crash protection for children or protection from the dangers of OOP air bag deployment. 
To minimize the risk that a child 
could ride in a front DSP without the protections afforded by advanced air bags, NHTSA seeks comment on whether ADS-equipped vehicles that have manual controls should not be capable of motion if a child is detected in the driver’s seat. This NPRM tentatively proposes that the following conditions would disallow vehicle motion: (1) The occupant of the seat is classified as a child, for which air bag suppression would be an option in a passenger seat, i.e., up to a 6-year-old as 
determined by the same test procedures used by air bag suppression (S20, S22 and S24); and (2) the vehicle is an operational state that does not require a driver, i.e., any situation where the ADS 
is under full control. An example of the new regulatory text to address this situation is provided in Table VI–5. Similar text has been added at S21.6 and S23.6. 
In developing this proposal, NHTSA 
considered myriad situations that are not currently probable in traditional motor vehicles. The agency requests comment on whether disallowing 
vehicle motion in ADS-equipped dual- mode vehicles when a child is seated behind driving controls is the most appropriate option for handling what could be a potentially life-threatening situation to a child. NHTSA’s core concern is the safety of all occupants, including children, and considers the potential risk to a child behind driving controls in a dual-mode ADS as both foreseeable and unacceptable. NHTSA also requests comment and technical information from industry on how they plan to protect children who may be seated behind driving controls in dual- mode vehicles. Additionally, the agency requests comment on if and how best NHTSA could conduct research to further explore how best to protect children who may be seated behind driving controls in dual-mode ADS- equipped vehicles.

No current regulatory text. 
After Change 
S19.5 Motion suppression for vehicles with 
manually-operated driving controls that do 
not require a driver. Each vehicle that is certified as complying with S14 shall not be capable of motion when a 12-month-old CRABI dummy is placed at the driver’s seating position and the vehicle is in an operational state that does not require a driver. 
S19.5.1 Motion suppression shall be as-
sessed under the test procedures specified in S20.1 through S20.2, except that the 12- month-old CRABI dummy is placed in the driver’s seating position and the result shall be an inability of engage vehicle motion. 
7. Driver’s Seat Used as a Spatial 
Reference 
i. Buses 
FMVSS No. 208, S4.4, addresses the 
belt and crash test requirements and 
options for buses, including school buses, of every weight class. In S4.4.1 
through S4.4.5, the driver’s DSP is used as a frame of reference, primarily for the installation of seat belts. Depending on the bus type and GVWR, the driver’s DSP is required to either be outfitted with a Type 1 or 2 seat belt or meet a crash test option. As is the case with vehicles other than buses, the regulatory text must address when the driver’s DSP is not present in an ADS-equipped vehicle. However, buses are unique in that the protection required for other vehicle seats depends on the location of the seat when compared to the location of the driver’s DSP. For example, S4.4.3.2.1 specifies the belt 
requirements for ‘‘any outboard designated seating position not rearward of the driver’s.’’ 
For ADS-equipped vehicles without 
driver’s seats, a direct translation could be achieved by simply substituting ‘‘left front outboard seat.’’ However, ADS- equipped vehicles may not have a left front outboard seat, so the agency sees no inherent reason to reference the left outboard seat over the right front outboard seat in these vehicles. Therefore, for vehicles without a driver’s seat, we propose to make references to both front row outboard seats, using the definition of ‘‘row’’ originally provided in FMVSS No. 226 and now being moved to Part 571.3. An example of this translation is provided below in Table VI–6, for school buses with a GVWR of 4,536 kg (10,000 lb) or less below. Similar changes can be found in S4.4.1 and S4.4.5.1.1. 
An alternative to referencing the 
outboard seats in the front ‘‘row’’ would be to have more simply specified front outboard seats. One challenge to this would be that bus seating configuration can be somewhat unique, with offset seats in the same row. Thus, referencing the front ‘‘row’’ may in some cases provide additional clarity. In similar situations for other vehicle types, it may not be necessary to refer to ‘‘row,’’ but just front outboard seats. 
We also seek comment on whether 
modifying the text below to reference only the front row, even in cases where a school bus has a driver’s DSP, is a viable option without any significant negative effect. 
TABLE VI–6

position and any outboard designated seat-

meet a crash test option. Seat belts provide protection in most types of crashes by keeping occupants within the vehicle and close to their original seating position, provide ‘‘ride-down’’ by gradually decelerating the occupant as the vehicle deforms and absorbs energy, and, if possible, prevent occupants from contacting harmful interior surfaces or one another.
63 
NHTSA is primarily concerned with ensuring safety, and requests comment on how best the agency can ensure that occupants receive the same protections they receive today. For ADS-equipped buses mentioned above, without a driver’s seat, NHTSA believes there are several distinct approaches to apply the protection requirements currently in this standard. First, NHTSA seeks comment on requiring all front seats have seat belts. Second, NHTSA seeks comment on requiring the right front outboard seating position to have a seat belt. Third, NHTSA requests comment on requiring at least one front passenger seat meet the required protections. Finally, NHTSA seeks comment on compartmentalization as a barrier to ejection, such as is required for passengers of school buses with a GVWR of more than 4,536 kg (10,000 lb). NHTSA tentatively proposes that all front passenger seats meet the protection requirements that must currently be met by the driver’s seat in order to maintain the safety need inherent within the current requirement for a seat belt. While NHTSA proposes this particular option, the agency notes that any or none of the abovementioned options could be selected depending on stakeholder feedback. 
Larger buses may only have a single 
front DSP, i.e., the driver’s seat, with the 
right front area being taken by access to the passenger rows. Thus, in these configurations there is no other front passenger to protect. As we stated above, an ADS-equipped bus may not have a left front outboard seat at all, but may have multiple front passenger seats. We cannot meaningfully predict where any front passenger seat might be in an ADS-equipped bus. Therefore, the proposal above aims to offer seat belt protection to all front passengers, in the interest of assuring that any front passenger in ADS vehicles, regardless of lateral seat location, would have an available seat belt. Our rationale is there is likely a similar safety risk in all front row seats and that the prediction of where an individual might sit in the front row is likely to change in ADS- equipped vehicles, rather than permitting manufacturers to arbitrarily choose which front row occupant receives the protection of a seat belt. 
Even so, the agency initially 
considered requiring a seat belt for a single front passenger in these buses, because doing so maintains the level of performance and protection currently required for non-ADS vehicles. Our reasoning was that any single vehicle occupant could choose to sit in the single seat location equipped with a belt, even if only one belted position were provided. We assume that if they chose to sit at a front seat location without a seat belt, they would either not be interested in wearing a seat belt, were not aware that a seat belt equipped DSP were present, or all other seats were taken. We think that lack of awareness of a seat belt is unlikely, due to the visibility of seat belts, although we have not studied this circumstance. We seek comment on whether it would be more appropriate to require seat belts at only one DSP, rather than at all front passenger seating position. Vehicles with a driver’s seat would continue being treated as they always have. These proposed changes can be found in S4.4.4.1.2, S4.4.4.2 and S4.4.5.3. We note that S4.4.4.1.1, which refers to a regulatory option for complete passive protection that to the agency’s knowledge has never been used, is not being modified in this proposal. We seek comment on the need to modify this seldom used regulatory option. 
ii. Dummy Placement in Bench Seats 
In light vehicles, the driver’s seat and 
the dummy placed there also provides 
a spatial reference point for the lateral positioning of the dummy in the outboard passenger seat on the other side of the vehicle. Currently, the passenger dummy is placed at the same lateral distance as the driver dummy from the vehicle longitudinal centerline. The driver is positioned by centering on the center of rotation of the steering control. When the driver reference is absent, as will be the case in ADS vehicles without driving controls, an alternative must be found for positioning of the passenger dummies. There are multiple approaches to this 
issue. One method would be to use the centerline of the head restraint on the left side or both sides of the vehicle. If just done on the left side, the right outboard passenger positioning would again use the left seat as a frame of reference. We have tentatively decided against this option because head restraints can sometimes be asymmetric. Instead, we are proposing to position both outboard passenger dummies by using the seating reference point of the DSP where they are located. We are no 
longer using the left outboard dummy position as a reference for the right outboard dummy, although, we would expect symmetry in most cases. This proposed approach ensures that there are available and easy-to-understand spatial references, regardless of front seat configuration in an ADS–DV. An example of this change is provided in Table VI–7, below. Other examples can be found in S10.4.1.1, S20.2.1.4, S20.2.2.3, S20.4.4, S22.2.1.3, S22.2.2.1, 
S22.2.2.3, S22.2.2.4, S22.2.2.5, S22.2.2.6, S22.2.2.7 and S24.2.3. 
We ask for comment on whether the 
text associated with a driver’s DSP could be deleted without any significant effect.

midsagittal plane of the dummy vertical and parallel to the vehicle’s longitudinal centerline and the same distance from the vehicle’s longitudinal centerline, within ±10 mm (±0.4 in), as the midsagittal plane of the driver dummy, if there is a driver’s seating position. Otherwise, the midsagittal plane of any front outboard passenger dummy shall be vertical, parallel to the ve-hicle’s longitudinal centerline, and pass, within ±10 mm (±0.4 in), through the seat-
ing reference point of the seat that it occu-pies. 
iii. Left Versus Right Vehicle Side 
In the performance of certain tests, 
specific steps in the vehicle preparation 
reference the driver’s side of the vehicle. In S13.3, the sill of the vehicle on the driver’s side is leveled. In this case, NHTSA believes that with a simple direct translation of ‘‘left side’’ there is no loss in meaning and the test can be performed just as effectively and achieve the same safety goal. The agency requests comment on whether stakeholders agree that this option will result in the same performance outcome. 
8. Direct Translations 
In some situations, a simple direct 
change from ‘‘driver’’ to ‘‘front left 
outboard’’ in the regulatory text is appropriate since there is no loss in meaning and the requirement or test

64As noted above, there are some standards that 
are applicable to trucks that we have chosen not to 
specify that they only apply if a DSP is present because the standard is clearly only applicable to DSP location. One such example is FMVSS No. 202a, which specifies the requirements for head restraints depending on the seating position, e.g., 
front outboard. Thus, if there are no seating positions, such as could be the case for a occupant- 
less vehicle, the restraint requirements do not apply. procedure being specified can be 
described or performed just as effectively and achieve the same safety outcome. Such a situation occurs in S16.2.10.3. In this example, the adjustment made to the driver’s seat also controls the passenger seat, such as is the case with a bench seat. NHTSA does not believe there will be any unwanted implications of the front left outboard seat adjustment of an ADS vehicle controlling the positioning of a bench seat, as opposed to the right front seat. We note that if the front left outboard seat does not exist, the regulatory text is still viable as it is currently written.

S16.2.10.3 Seat position adjustment. If the 
passenger seat does not adjust independ-
ently of the driver seat, the driver seat shall control the final position of the pas-senger seat. 
After Change 
S16.2.10.3 Seat position adjustment. If the 
front right outboard passenger seat does not adjust independently of the front left outboard seat, the front left outboard seat shall control the final position of the front right outboard passenger seat. 
9. Minor Editorial Revisions 
At every occurrence of the term 
‘‘steering wheel,’’ we have substituted 
the term ‘‘steering control.’’ These terms are synonymous as can be seen by the definition of ‘‘steering control system.’’ 
Nonetheless, the agency believes there is some merit in changing ‘‘wheel’’ to ‘‘control’’ in consideration of steering controls that may not be circular, e.g., shaped more like an air plane yoke control. We note that such systems would have both a ‘‘hub’’ about which they turn and a rim, i.e., an outer edge. 
A similar change was made in every FMVSS that is the subject of this NPRM. 
10. Regulatory Text Not Modified Due to 
Non-Active Requirements 
Various sections of the regulatory text 
of FMVSS No. 208 are no longer active because they have been superseded by revisions NHTSA has made over the years. NHTSA has tentatively decided to only provide translated regulatory text for active sections. However, even though a particular section may state its applicability is outdated for a particular vehicle type, this same section may be referenced for another vehicle type still in production. Therefore, care needs to be taken in determining which sections need not be translated. Table VI–9 lists the sections that make some reference to ‘‘driver’’ or ‘‘steering wheel/control,’’ but have not been updated through this document since they are no longer active. The form of the translation that would have been required to these sections, if any, has not be determined. NHTSA seeks comment on whether this is the correct approach. 
TABLE VI–9 
Section for Which No Translation Has Been 
Provided 
S4.1.3.4(a)(1) and (2), S4.1.4.1, S4.1.5.2.1, 
S4.1.5.3, S4.2.1.2(b), S4.2.5.4(c), 
S4.2.5.5(a)(1) and (2), S4.2.6.1.1, S4.2.6.2, S4.5.3.3(b)(B), S4.5.4.1(b)(2), S4.5.4.2. 
b. FMVSS No. 201; Occupant Protection 
in Interior Impacts 
FMVSS No. 201 sets out performance 
requirements to protect occupants from injury due to impact with interior surfaces. Many of these requirements state that certain defined areas of the vehicle’s interior must provide a minimum level of protection when impacted by a test device. Currently, the standard describes many of these defined impact areas with references to the driver’s seating position and steering control. 
We propose to amend FMVSS No. 201 
to permit the certification of vehicles without a driver’s seat or steering controls. The proposed changes are described below. 
1. Application Section 
NHTSA proposes to modify the 
application section (S2) so that the 
standard would apply to trucks only if they have at least one DSP. As discussed in the portion of this document focused on FMVSS No. 208, the rationale behind this modification rests primarily on lack of clarity on how to test and concerns about the necessity of testing occupant- less trucks to this standard, as they would have no occupants or DSPs. Additionally, NHTSA tentatively concludes that the safety need that supports the crashworthiness requirement of FMVSS No. 201 for the protection of vehicle occupants does not exist for occupant-less trucks. Accordingly, NHTSA has tentatively decided to propose amending the application section of FMVSS No. 201 to apply only to trucks with DSPs.
64 2. Modifications To Address That There 
May Be No Driver’s Seat and Multiple Outboard Passenger Seats 
Sections S5.1, S5.1.2, and S8.24 
would be modified to allow multiple front outboard passengers. (See explanation in section VI.a.2.) 
3. Driver’s Seat Used as Spatial 
Reference 
NHTSA proposes to modify 
definitions for ‘‘A-pillar;’’ ‘‘B-pillar;’’ and ‘‘pillar’’ in S3, and the partial carve- out in S6.3(b) for altered vehicles and vehicles manufactured in multiple stages to use ‘‘the most rearward designated seating position in the forward row’’ as a reference point (instead of the ‘‘driver’s seat) to describe a spatial plane. (See explanation in section VI.a.7.i.) For the exclusion for multistage vehicles provided in S6.3(a), we note that specifying the rearmost seating reference point is consistent with the excluded area for non- multistage vehicles. However, the excluded area might be larger if the forward most seating reference point were used as a reference. Whether the excluded area would be larger or smaller than a vehicle with a driver’s seat would depend on the relative position of the driver’s seat. We seek comment on whether the excluded area should be more or less inclusive for multistage vehicles and the means to achieve any suggested recommendation. 
TABLE VI–10 
Before Change 
A-pillar means any pillar that is entirely for-
ward of a transverse vertical plane passing 
through the seating reference point of the driver’s seat. 
After Change 
A-pillar means any pillar that is entirely for-
ward of a transverse vertical plane passing through the seating reference point of the driver’s designated seating position or, if there is no driver’s designated seating po-sition, any pillar that is entirely forward of a transverse vertical plane passing through the seating reference point of the rearmost designated seating position in the front row of seats. 
4. Steering Control Used as a Spatial 
Reference 
NHTSA proposes to modify Section 
S5.1.1(d), which states that S5.1 does not apply to certain areas of the 
VerDate Sep<11>2014 18:23 Mar 27, 2020 Jkt 250001 PO 00000 Frm 00017 Fmt 4701 Sfmt 4702 E:\FR\FM\30MRP2.SGM 30MRP2lotter on DSKBCFDHB2PROD with PROPOSALS217640 Federal Register / Vol. 85, No. 61 / Monday, March 30, 2020 / Proposed Rules 
65We note that, because most vehicles to which 
FMVSS No. 203 applies are not required to be 
equipped with air bags, NHTSA believes that a passenger seat that meets FMVSS No. 201 may provide equal or greater occupant protection than a driver’s seat that is equipped with steering controls that meet FMVSS No. 203. In the absence of air bags, NHTSA believes that a passenger seat that has no steering controls would be safer than a driver’s seat with a FMVSS No. 203-compliant steering column, because the presence of a steering column could itself increase risk of injury due to its proximity to the driver in a crash. 
66We note that an identical test step is performed 
on the ‘‘opposite’’ side of the vehicle. instrument panel that are bounded by 
the inboard edge of the steering control, so that it would apply only if a steering wheel is present. This change would clarify that S5.1.1(d) would not apply 
on a vehicle without a steering control. 
c. FMVSS No. 203; Impact Protection for 
the Drivers From the Steering Control System, and FMVSS No. 204; Steering Control Rearward Displacement 
NHTSA proposes modifying the 
Application section (S2) of FMVSS No. 203 and the Application section (S2) of FMVSS No. 204 to state that the standards do not apply to vehicles without steering controls. The agency believes that these proposed changes would not reduce vehicle safety because, if there is no steering control present at the seating position where the driver’s seat would normally be located, that seating position would become a passenger seat that is still subject to the protection afforded by the requirements of FMVSS No. 201.
65 
We note that this approach addresses 
multiple RFC comments. As discussed in the comment summary, some commenters seemed to believe that this standard simply would not apply to ADS–DVs without traditional manual controls, while others requested that NHTSA clearly indicate the applicability of this standard to these vehicles in the regulatory text. Some manufacturers have petitioned NHTSA for an exemption from FMVSS Nos. 203 and 204, which indicates that some companies may be unsure of whether these standards were if-equipped standards or included a requirement to equip vehicles with steering control systems. In developing a solution for resolving these ambiguities, NHTSA also assessed whether elimination of this standard for vehicles without steering controls, i.e. ADS-equipped 
vehicles without traditional manual controls, will maintain the level of crashworthiness protection among vehicles with or without ADS functionality. We have tentatively concluded that safety will be maintained due to the modifications that we have made to other standards to ensure the protection of that occupant (especially the changes proposed for FMVSS Nos. 201 and 208). 
In addition to the change in 
applicability, we propose to move the definition of ‘‘steering control system’’ in FMVSS No. 203 to Part 571.3, as we discussed above in section V.b. 
d. FMVSS No. 205; Glazing Materials 
NHTSA proposes modifying the 
Application Section (S3) so that the 
standard would apply to trucks only if they have at least one DSP for the reasons discussed in previous sections of this notice. In particular, see the discussions of this issue in the FMVSS No. 208 and FMVSS No. 201 sections. (See explanation in sections VI.a.1 and VI.b.1.) No other changes are proposed. 
e. FMVSS No. 206; Door Locks and Door 
Retention Components 
NHTSA proposes modifying the 
Application Section (S2) so that the standard would apply to trucks only if they have at least one DSP for the reasons discussed in previous sections of this notice. In particular, see the discussions of this issue in the FMVSS No. 208 and FMVSS No. 201 sections. (See explanation in sections VI.a.1 and VI.b.1.) 
This NPRM also proposes to modify 
the definitions for ‘‘side front door’’ and ‘‘side rear door,’’ which use the ‘‘driver’s seat back’’ as a spatial frame of reference, so that they can also apply to vehicles without a driver’s seat. (See explanation in section VI.b.1.) 
The test procedure step in S5.1.1.4, 
would be modified to replace a reference to the ‘‘driver’s side’’ of the vehicle with ‘‘left side.’’
66(See 
explanation in section VI.a.7.iii.) We note that, since both sides of the vehicle are tested, ADS and non-ADS vehicles would continue to be subject to identical testing requirements. 
f. FMVSS No. 207; Seating Systems 
NHTSA proposes modifying the 
Application Section (S2) so that the 
standard would apply to trucks only if they have at least one DSP for the reasons discussed in previous sections of this notice. In particular, see the discussions of this issue in the FMVSS No. 208 and FMVSS No. 201 sections. (See explanation in sections VI.a.1 and VI.b.1.) 
NHTSA proposes to modify the 
requirement that a vehicle have a driver’s seat (S4.1) to specify that a driver’s seat would be required only for vehicles with manually-operated driving controls. This leaves unchanged the requirement of S4.1 for non-ADS vehicles. By virtue of the new definition of driver’s seat (driver’s designated seating position) and manually-operated driving controls, a driver’s seat must have immediate access to such controls. Therefore, the proposed addition to S4.1 would clarify that a vehicle equipped with ADS without traditional driving controls need not have a driver’s seat. However, an ADS-equipped vehicle with driving controls would still need to have a driver’s seat. 
g. FMVSS No. 214; Side Impact 
Protection 
The proposed translations to FMVSS 
No. 214 match closely with the proposed changes to FMVSS No. 208. Like FMVSS No. 208, FMVSS No. 214 currently applies to all trucks, including occupant-less trucks that have no DSPs. Because occupant-less trucks would presumably have no DSPs, it is unclear how the dynamic side impact crash tests could be performed and whether the safety need of FMVSS No. 214 supports the requirements of the standard for the protection occupants in an occupant- less truck. Therefore, NHTSA proposes amending the application section of FMVSS No. 214 to apply only to trucks with DSPs. Additionally, as with FMVSS No. 208, NHTSA proposes clarifying that there may be multiple front outboard passengers by using the phrase ‘‘any front outboard passenger.’’ NHTSA also proposes clarifying the test dummy positioning on bench seats by using the seating reference point of the DSP where they are located. Finally, NHTSA proposes clarifying that the ‘‘driver’s side’’ now means the vehicle left side for spatial reference purposes. Table VI–11 below, provides the types of translations, the regulatory text section with examples of the change and the section number or this NPRM where a more detailed explanation of the change can be found.

h. FMVSS No. 216a; Roof Crush 
Resistance 
NHTSA proposes to modify the 
Application Section (S3) so that the standard would apply to trucks only if they have at least one DSP for the reasons discussed in previous sections of this notice. In particular, see the discussions of this issue in the FMVSS No. 208 and FMVSS No. 201 sections. (See explanation in section VI.a.1 and VI.b.1.) 
NHTSA proposes to modify the 
procedures for setting up the vehicle for testing in S7.1 to reference the left side and right side of the vehicle rather than the driver’s side and passenger’s side. (See explanation in VI.a.7.iii.) 
i. FMVSS No. 225; Child Restraint 
Anchorage Systems 
NHTSA proposes to modify the 
definition of ‘‘shuttle bus’’ to clarify that if the bus does not have a driver’s seat, it meets the definition of a shuttle bus if it has only one row of forward-facing seating positions rearward of the front row, rather than only one row of forward-facing seating positions rearward of the driver’s seat. Thus, the front row is used as the frame of reference rather than the driver’s seat, when there is no driver’s seat. (See explanation in section VI.a.7.i.) 
j. FMVSS No. 226; Ejection Mitigation 
NHTSA proposes to modify the 
Application Section (S2) so that the 
standard would apply to trucks only if they have at least one DSP for the reasons discussed in previous sections of this notice. In particular, see the discussions of this issue in the FMVSS No. 208 and FMVSS No. 201 sections. (See explanation in sections VI.a.1 and VI.b.1.) 
The existing definition of ‘‘modified 
roof’’ (in S3) uses the term ‘‘driver’s compartment.’’ This is a definition that provides an exclusion from the standard for vehicles with ‘‘modified roofs.’’ NHTSA proposes to make a simple substitution of ‘‘occupant compartment.’’ We note that this change is not specific to vehicles without drivers, but will affect all vehicles to which this standard applies. However, we expect that it will not have any substantive effect on non-ADS vehicles, i.e., we expect that the driver’s 
compartment and the occupant compartment will identical. Thus, NHTSA does not expect or intend additional vehicles to be excluded from the standard, but seeks comment on whether this is accurate. 
S6.1(d) and (f) include test procedure 
requirements that reference ‘‘driver door sill’’ for vehicle setup. NHTSA proposes to simply change those references to ‘‘left front door sill,’’ similar to what was explained in VI.a.7.iii. 
k. Regulatory Text Related to Parking 
Brake and Transmission Position 
The crash tests required by the 200 
Series standards, in general, do not require manually driving controls in order to conduct the tests. For example, in the full frontal test of FMVSS No. 208 the vehicle is towed down a test track and guided by a rail into a rigid barrier. There is no need to use the vehicle controls to steer the vehicle or control the impact speed. This does require the vehicle to have the vehicle transmission in neutral and no brakes applied. In contrast, the moving deformable barrier side crash test in FMVSS No. 214 requires the vehicle to be stationary, with the parking brake applied. In fact, multiple 200 (FMVSS Nos. 208, 214, and 212) and 300 (FMVSS Nos. 301, 303, and 305) Series standards include regulatory text that dictates the status of the vehicles parking brake and transmission. However, in some instances, this detail is left for the Compliance Test Procedure that accompanies the regulatory text. NHTSA realizes that for vehicles without driver-accessible parking brakes or transmission selectors, how to properly prepare the vehicle for testing may not be immediately obvious. However, this situation is not totally unique or novel even for conventional non-ADS vehicles. NHTSA has tested vehicles with automatic electronic parking brakes and electronic gear selectors, which may make it challenging to place the vehicle transmission and brake into the pre-test position. In these instances, NHTSA and its testing laboratories have worked with the vehicle manufacturers to achieve the necessary vehicle status. Thus, we are not currently proposing any regulatory text changes related to interfacing with ADS-equipped vehicles on pre-test brake and transmission status since the important element is whether the transmission is in the proper gear and whether the pre-test brake is activated— not the manner in which this state is achieved. NHTSA expects that manufacturers will provide the means for the agency to achieve the necessary brake and transmission status, if only for compliance testing purposes. We seek comment on the validity or our assumption and the proposed approach. 
VII. Cost Impacts of This 
Modernization Effort 
A Preliminary Regulatory Impact 
Analysis (PRIA) can be found in the docket for this NPRM. A summary of the PRIA findings are provided below. The agency solicits comment on the PRIA. NHTSA calculated the impact of the proposed rule on costs by analyzing production cost savings arising from forgoing the installation of manual steering controls. These cost savings are partially offset by incremental costs associated with augmenting safety equipment in the left front seating position to make that position equivalent to the right front seating position, i.e., when what would have 
previously been a driver’s seating position would become a passenger seating position in an ADS–DV without manual controls. 
Monetized estimated per-vehicle cost 
impacts (2018 dollars) are presented by discount rate in Table VII–1 below based on a scenario presented by the Energy Information Administration

(EIA), in which ADS–DVs represent 31

The ranges of estimates were 
identified within an uncertainty analysis addressing uncertainty in the average level of cost savings that would be achieved by ADS–DV manufacturers. The uncertainty analysis centered on identifying plausible ranges of the per- vehicle cost savings, with corresponding assumptions regarding the distributions of values across each range (i.e., the 
likelihood of observing a particular value). The uncertainty analysis generated 50,000 simulated outcomes, across which the mean and percentile values reported in Table VII–2 were identified. In addition to the above ranges of estimates, the agency performed a sensitivity analysis in which 30 percent of ADS–DV sales in 2050 are comprised of dual-mode vehicles. See the PRIA for the results of that analysis. 
We request comment on this approach 
to representing the range of estimated impacts under uncertainty. 
NHTSA assumed that light-duty 
vehicle sales would follow the identical 
baseline path specified in the Preliminary Regulatory Impact Analysis for the Safer Affordable Fuel-Efficient Vehicle rule
68through 2032 (the last 
year specified in the baseline), and then would continue to grow at the average annual growth rate in the baseline from 2028–2032 (approximately 0.2 percent per year) for each year after 2032, growing to 18.7 million new light-duty vehicles sold in 2050. NHTSA assumed that the share of new light-duty vehicle sales comprised of ADS–DVs would reach 31 percent in the year 2050, based on the EIA scenario described above;
69 
thus, new ADS–DV sales in 2050 are assumed to be equal to 31 percent of 18.7 million, or 5.8 million. Based on these assumptions, NHTSA estimates that the proposed rule would save ADS– DV manufacturers and consumers approximately $2.3 billion in the year 2050 (fifth-percentile estimate of $1.5 billion and 95th-percentile estimate of $3.1 billion) when discounting back to 2019 at a three-percent discount rate. At a seven-percent discount rate, the proposed rule is estimated to save ADS– DV manufacturers and consumers approximately $0.7 billion in the year 2050 (fifth-percentile estimate of $0.5 billion and 95th-percentile of $1.0 billion).

VIII. Regulatory Notices and Analyses 
a. Executive Order 13771 
This proposed rule is expected to be 
an Executive Order 13771 deregulatory 
action. Details on the estimated cost savings of this proposed rule can be found in the preamble’s discussion on cost impacts and in the accompanying supporting document providing further discussion in the docket for this NPRM. 
b. Executive Order 12866, Executive 
Order 13563, and DOT Regulatory Policies and Procedures 
Executive Order 12866, ‘‘Regulatory 
Planning and Review’’ (58 FR 51735, October 4, 1993), as amended by Executive Order 13563, ‘‘Improving Regulation and Regulatory Review’’ (76 FR 3821, January 21, 2011), provides for making determinations whether a regulatory action is ‘‘significant’’ and therefore subject to OMB review and to the requirements of the Executive Order. The Order defines a ‘‘significant regulatory action’’ as one that is likely to result in a rule that may: 
•Have an annual effect on the economy of 
$100 million or more or adversely affect in 
a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or Tribal governments or communities; 
•Create a serious inconsistency or 
otherwise interfere with an action taken or planned by another agency; 
•Materially alter the budgetary impact of 
entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or •Raise novel legal or policy issues arising 
out of legal mandates, the President’s 
priorities, or the principles set forth in the Executive Order. 
This action was reviewed by the 
Office of Management and Budget under E.O. 12866. This action is a significant regulatory action within the meaning of E.O. 12866 and under the Department of Transportation’s regulatory policies and procedures (44 FR 11034, February 26, 1979). 
This action is significant because it 
raises the novel legal and policy issues surrounding the regulation of vehicles equipped with ADS and is the subject of much public interest. The cost savings of this deregulatory proposal are described in the preamble and discussed in greater detail in the accompanying cost savings document included in this docket. 
c. Regulatory Flexibility Act 
Pursuant to the Regulatory Flexibility 
Act (5 U.S.C. 601 et seq., as amended by 
the Small Business Regulatory Enforcement Fairness Act (SBREFA) of 1996), whenever an agency is required to publish a notice of proposed rulemaking or final rule, it must prepare and make available for public comment a regulatory flexibility analysis that describes the effect of the rule on small entities (i.e., small businesses, small 
organizations, and small governmental jurisdictions). The Small Business Administration’s regulations at 13 CFR part 121 define a small business, in part, 
as a business entity ‘‘which operates primarily within the United States.’’ (13 CFR 121.105(a)(1)). No regulatory flexibility analysis is required if the head of an agency certifies the proposal will not have a significant economic impact on a substantial number of small entities. SBREFA amended the Regulatory Flexibility Act to require Federal agencies to provide a statement of the factual basis for certifying that a proposal will not have a significant economic impact on a substantial number of small entities. 
This action proposes amendments to 
and clarifies the application of existing occupant protection standards to vehicles equipped with ADS that also lack traditional manual controls. This proposed rule would apply to small motor vehicle manufacturers who wish to produce ADS without manual controls and with conventional seating arrangements (i.e., forward-facing, front 
row seats). NHTSA analyzed current small manufacturers and current small ADS developers in detail in the PRIA, and found that none of the entities listed in the analysis would be impacted by this proposal. Thus, I hereby certify

that this proposed rule would not have 
a significant economic impact on a substantial number of small entities. Additional details related to the basis of this finding can be found in the PRIA for this rulemaking proposal. 
d. Executive Order 13132 (Federalism) 
NHTSA has examined this proposal 
pursuant to Executive Order 13132 (64 
FR 43255, August 10, 1999) and concluded that no additional consultation with States, local governments or their representatives is mandated beyond the rulemaking process. The agency has concluded that the rulemaking will not have sufficient federalism implications to warrant consultation with State and local officials or the preparation of a federalism summary impact statement. The proposal will not have ‘‘substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.’’ 
NHTSA rules can preempt in two 
ways. First, the National Traffic and Motor Vehicle Safety Act contains an express preemption provision: When a motor vehicle safety standard is in effect under this chapter, a State or a political subdivision of a State may prescribe or continue in effect a standard applicable to the same aspect of performance of a motor vehicle or motor vehicle equipment only if the standard is identical to the standard prescribed under this chapter. 49 U.S.C. 30103(b)(1). It is this statutory command by Congress that preempts any non- identical State legislative and administrative law addressing the same aspect of performance. 
The express preemption provision 
described above is subject to a savings clause under which ‘‘[c]ompliance with a motor vehicle safety standard 
prescribed under this chapter does not exempt a person from liability at common law.’’ 49 U.S.C. 30103(e). Pursuant to this provision, State common law tort causes of action against motor vehicle manufacturers that might otherwise be preempted by the express preemption provision are generally preserved. However, the Supreme Court has recognized the possibility, in some instances, of implied preemption of such State common law tort causes of action by virtue of NHTSA’s rules, even if not expressly preempted. This second way that NHTSA rules can preempt is dependent upon there being an actual conflict between an FMVSS and the higher standard that would effectively be imposed on motor vehicle 
manufacturers if someone obtained a State common law tort judgment against the manufacturer, notwithstanding the manufacturer’s compliance with the NHTSA standard. Because most NHTSA standards established by an FMVSS are minimum standards, a State common law tort cause of action that seeks to impose a higher standard on motor vehicle manufacturers will generally not be preempted. However, if and when such a conflict does exist—for example, when the standard at issue is both a minimum and a maximum standard— the State common law tort cause of action is impliedly preempted. See Geier v. American Honda Motor Co., 
529 U.S. 861 (2000). 
Pursuant to Executive Orders 13132 
and 12988, NHTSA has considered whether this proposal could or should preempt State common law causes of action. The agency’s ability to announce its conclusion regarding the preemptive effect of one of its rules reduces the likelihood that preemption will be an issue in any subsequent tort litigation. 
To this end, the agency has examined 
the nature (e.g., the language and 
structure of the regulatory text) and objectives of this proposal and finds that this proposal, like many NHTSA rules, would prescribe only a minimum safety standard. As such, NHTSA does not intend that this proposal preempt state tort law that would effectively impose a higher standard on motor vehicle manufacturers than that to be established by this proposal. Establishment of a higher standard by means of State tort law would not conflict with the minimum standard announced here. Without any conflict, there could not be any implied preemption of a State common law tort cause of action. 
e. Executive Order 12988 (Civil Justice 
Reform) 
When promulgating a regulation, 
Executive Order 12988 specifically requires that the agency must make every reasonable effort to ensure that the regulation, as appropriate: (1) Specifies in clear language the preemptive effect; (2) specifies in clear language the effect on existing Federal law or regulation, including all provisions repealed, circumscribed, displaced, impaired, or modified; (3) provides a clear legal standard for affected conduct rather than a general standard, while promoting simplification and burden reduction; (4) specifies in clear language the retroactive effect; (5) specifies whether administrative proceedings are to be required before parties may file suit in court; (6) explicitly or implicitly defines key terms; and (7) addresses 
other important issues affecting clarity and general draftsmanship of regulations. 
Pursuant to this Order, NHTSA notes 
as follows. The preemptive effect of this proposed rule is discussed above in connection with E.O. 13132. NHTSA notes further that there is no requirement that individuals submit a petition for reconsideration or pursue other administrative proceeding before they may file suit in court. 
f. Executive Order 13045 (Protection of 
Children From Environmental Health 
and Safety Risks) 
Executive Order 13045, ‘‘Protection of 
Children from Environmental Health and Safety Risks,’’ (62 FR 19885; April 23, 1997) applies to any proposed or final rule that: (1) Is determined to be ‘‘economically significant,’’ as defined in E.O. 12866, and (2) concerns an environmental health or safety risk that NHTSA has reason to believe may have a disproportionate effect on children. If a rule meets both criteria, the agency must evaluate the environmental health or safety effects of the rule on children, and explain why the rule is preferable to other potentially effective and reasonably feasible alternatives considered by the agency. 
This proposed rule is not expected to 
have a disproportionate health or safety impact on children. Consequently, no further analysis is required under Executive Order 13045. 
g. Executive Order 13609, Promoting 
International Regulatory Cooperation 
Executive Order 13609, ‘‘Promoting 
International Regulatory Cooperation,’’ promotes international regulatory cooperation to meet shared challenges involving health, safety, labor, security, environmental, and other issues and to reduce, eliminate, or prevent unnecessary differences in regulatory requirements. NHTSA has analyzed this proposed rule under the policies and agency responsibilities of Executive Order 13609, and has determined this proposal would have no effect on international regulatory cooperation. 
h. Paperwork Reduction Act 
Under the Paperwork Reduction Act 
of 1995 (PRA), a person is not required 
to respond to a collection of information by a Federal agency unless the collection displays a valid OMB control number. This proposed rule imposes no new reporting requirements on manufacturers.

i. National Technology Transfer and 
Advancement Act 
Under the National Technology 
Transfer and Advancement Act of 1995 (NTTAA) (Pub. L. 104–113), ‘‘all Federal agencies and departments shall use technical standards that are developed or adopted by voluntary consensus standards bodies, using such technical standards as a means to carry out policy objectives or activities determined by the agencies and departments.’’ Voluntary consensus standards are technical standards (e.g., materials 
specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies, such as SAE. The NTTAA directs us to provide Congress, through OMB, explanations when we decide not to use available and applicable voluntary consensus standards. 
Pursuant to the above requirements, 
the agency conducted a review of voluntary consensus standards to determine if any were applicable to this proposed rule. NHTSA searched for but did not find voluntary consensus standards directly applicable to the amendments proposed in this NPRM. Neither is NHTSA aware of any international regulations of Global Technical Regulation (GTR) activity addressing the subject of this proposal. 
j. Unfunded Mandates Reform Act 
Section 202 of the Unfunded 
Mandates Reform Act of 1995 (UMRA) 
requires federal agencies to prepare a written assessment of the costs, benefits, and other effects of proposed or final rules that include a Federal mandate likely to result in the expenditure by State, local, or tribal governments, in the aggregate, or by the private sector, of more than $100 million annually (adjusted for inflation with base year of 1995). Before promulgating a rule for which a written statement is needed, section 205 of the UMRA generally requires the agency to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost-effective, or least burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows the agency to adopt an alternative other than the least costly, most cost-effective, or least burdensome alternative if the agency publishes with the final rule an explanation of why that alternative was not adopted. 
Although this proposed rule is a 
significant regulatory action, it does not contain a mandate that would impose costs on the private sector of more than $100 million annually (adjusted for inflation with base year of 1995). As a result, the requirements of Section 202 of the Act do not apply. 
k. National Environmental Policy Act 
NHTSA has analyzed this rulemaking 
action for the purposes of the National 
Environmental Policy Act. The agency has determined that implementation of this proposed action will not have any significant impact on the quality of the human environment. 
l. Plain Language 
Executive Order 12866 requires each 
agency to write all rules in plain 
language. Application of the principles of plain language includes consideration of the following questions: 
•Have we organized the material to suit 
the public’s needs? 
•Are the requirements in the rule clearly 
stated? 
•Does the rule contain technical language 
or jargon that isn’t clear? 
•Would a different format (grouping and 
order of sections, use of headings, 
paragraphing) make the rule easier to understand? 
•Would more (but shorter) sections be 
better? 
•Could we improve clarity by adding 
tables, lists, or diagrams? 
•What else could we do to make the rule 
easier to understand? 
If you have any responses to these 
questions, please include them in your 
comments on this proposal. 
m. Regulation Identifier Number (RIN) 
The Department of Transportation 
assigns a regulation identifier number 
(RIN) to each regulatory action listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. You may use the RIN contained in the heading at the beginning of this document to find this action in the Unified Agenda. 
IX. Regulatory Text List of Subjects in 49 CFR Part 571

S16.3.2.1.8 If needed, extend the 
legs slightly so that the feet are not in 
contact with the floor pan. Let the thighs rest on the seat cushion to the extent permitted by the foot movement. Keeping the leg and the thigh in a vertical plane, place the foot in the vertical longitudinal plane that passes through the centerline of the accelerator pedal. Rotate the left thigh outboard about the hip until the center of the knee is the same distance from the midsagittal plane of the dummy as the right knee ±5 mm (±0.2 in). Using only the control that primarily moves the seat fore and aft, attempt to return the seat to the full forward position. If either of the dummy’s legs first contacts the steering control, then adjust the steering control, if adjustable, upward until contact with the steering control is avoided. If the steering control is not adjustable, separate the knees enough to avoid steering control contact. Proceed with moving the seat forward until either the leg contacts the vehicle interior or the seat reaches the full forward position. (The right foot may contact and depress the accelerator and/ or change the angle of the foot with respect to the leg during seat movement.) If necessary to avoid contact with the vehicles brake or clutch pedal, rotate the test dummy’s left foot about the leg. If there is still interference, rotate the left thigh outboard about the hip the minimum distance necessary to avoid pedal interference. If a dummy leg contacts the vehicle interior before the full forward position is attained, position the seat at the next detent where there is no contact. If the seat is a power seat, move the seat fore and aft to avoid contact while assuring that there is a maximum of 5 mm (0.2 in) distance between the vehicle interior and the point on the dummy that would first contact the vehicle interior.

For vehicles with adjustable seat backs, while holding the thighs in place, rotate the seat back forward until the transverse instrumentation platform of the head is level to within ±0.5 degree, making sure that the pelvis does not interfere with the seat bight. Inspect the abdomen to ensure that it is properly installed. If the torso contacts the steering control, adjust the steering control in the following order until there is no contact: Telescoping adjustment, lowering adjustment, raising adjustment. If the vehicle has no adjustments, or contact with the steering control cannot be eliminated by adjustment, position the seat at the next detent where there is no contact with the steering control as adjusted in S16.2.9. If the seat is a power seat, position the seat to avoid contact while assuring that there is a maximum of 5 mm (0.2 in) distance between the steering control as adjusted in S16.2.9 and the point of contact on the dummy.

S8.4 Adjustable steering controls. 
Adjustable steering controls are adjusted 
so that the steering control hub is at the geometric center of the locus it describes when it is moved through its full range of driving positions. If there is no setting detent in the mid-position, lower the steering control to the detent just below the mid-position. If the steering column is telescoping, place the steering column in the mid-position. If there is no mid-position, move the steering control rearward one position from the mid-position.

S10.2 Vehicle test attitude. When 
the vehicle is in its ‘‘as delivered,’’ 
‘‘fully loaded’’ and ‘‘as tested’’ condition, locate the vehicle on a flat, horizontal surface to determine the vehicle attitude. Use the same level surface or reference plane and the same standard points on the test vehicle when determining the ‘‘as delivered,’’ ‘‘fully loaded’’ and ‘‘as tested’’ conditions. Measure the angles relative to a horizontal plane, front-to-rear and from left-to-right for the ‘‘as delivered,’’ ‘‘fully loaded,’’ and ‘‘as tested’’ conditions. The front-to-rear angle (pitch) is measured along a fixed reference on the left and right front occupant’s door sills. Mark where the angles are taken on the door sills. The left to right angle (roll) is measured along a fixed reference point at the front and rear of the vehicle at the vehicle longitudinal center plane. Mark where the angles are measured. The ‘‘as delivered’’ condition is the vehicle as received at the test site, with 100 percent of all fluid capacities and all tires inflated to the manufacturer’s specifications listed on the vehicle’s tire placard. When the vehicle is in its ‘‘fully loaded’’ condition, measure the angle between the left front occupant’s door sill and the horizontal, at the same place the ‘‘as delivered’’ angle was measured. The ‘‘fully loaded condition’’ is the test vehicle loaded in accordance with S8.1 of this standard (49 CFR 571.214). The load placed in the cargo area is centered over the longitudinal centerline of the vehicle. The vehicle ‘‘as tested’’ pitch and roll angles are between the ‘‘as delivered’’ and ‘‘fully loaded’’ condition, inclusive.

of the test dummy rests against the seat 
back. The midsagittal plane of the test dummy is vertical and parallel to the vehicle’s longitudinal centerline. For vehicles with manually-operated driving controls the midsagittal plane of the test dummy is the same distance from the vehicle’s longitudinal centerline as would be the midsagittal plane of a test dummy positioned in the driver’s seating position under S12.1.1(a)(1). For vehicles without manually-operated driving controls the midsagittal plane of the test dummy shall be vertical and parallel to the vehicle’s longitudinal centerline, and passes through any front outboard passenger seat’s SgRP.

(8) If needed, extend the legs slightly 
so that the feet are not in contact with 
the floor pan. Let the thighs rest on the seat cushion to the extent permitted by the foot movement. Keeping the leg and 
the thigh in a vertical plane, place the foot in the vertical longitudinal plane that passes through the centerline of the accelerator pedal. Rotate the left thigh outboard about the hip until the center of the knee is the same distance from the midsagittal plane of the dummy as the right knee ±5 mm (±0.2 in). Using 
only the control that moves the seat fore and aft, attempt to return the seat to the full forward position. If either of the dummy’s legs first contacts the steering control, then adjust the steering control, if adjustable, upward until contact with the steering control is avoided. If the steering control is not adjustable, separate the knees enough to avoid steering control contact. Proceed with moving the seat forward until either the leg contacts the vehicle interior or the seat reaches the full forward position. (The right foot may contact and depress the accelerator and/or change the angle of the foot with respect to the leg during seat movement.) If necessary to avoid contact with the vehicle’s brake or clutch pedal, rotate the test dummy’s left foot about the leg. If there is still interference, rotate the left thigh outboard about the hip the minimum distance necessary to avoid pedal interference. If a dummy leg contacts the vehicle interior before the full forward position is attained, position the seat at the next detent where there is no contact. If the seat is a power seat, move the seat fore and aft to avoid contact while assuring that there is a maximum of 5 mm (0.2 in) distance between the vehicle interior and the point on the dummy that would first contact the vehicle interior. If the steering control was moved, return it to the position described in S10.5. If the steering control contacts the dummy’s leg(s) prior to attaining this position, adjust it to the next higher detent, or if infinitely adjustable, until there is 5 mm (0.2 in) clearance between the control and the dummy’s leg(s).

instrumentation platform angle to within ±0.5 degrees if possible. If it is 
still not possible to level the transverse instrumentation platform to within ±0.5 degrees, select the neck bracket angle position that minimizes the difference between the transverse instrumentation platform angle and level. 
(10) If the torso contacts the steering 
control, adjust the steering control in the following order until there is no contact: Telescoping adjustment, lowering adjustment, raising adjustment. If the vehicle has no adjustments or contact with the steering control cannot be eliminated by adjustment, position the seat at the next detent where there is no contact with the steering control as adjusted in S10.5. If the seat is a power seat, position the seat to avoid contact while assuring that there is a maximum of 5 mm (0.2 in) distance between the steering control as adjusted in S10.5 and the point of contact on the dummy.
