Federal Motor Vehicle Safety Standard No. 141, Minimum Sound 
Requirements for Hybrid and Electric Vehicles

AGENCY: National Highway Traffic Safety Administration (NHTSA), 
Department of Transportation (DOT).

ACTION: Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: This notice proposes to amend Federal Motor Vehicle Safety 
Standard (FMVSS) No. 141, Minimum Sound Requirements for Hybrid and 
Electric Vehicles, to allow manufacturers of hybrid and electric 
vehicles (HEVs) to install a number of driver-selectable pedestrian 
alert sounds in each HEV they manufacture. This proposal responds to a 
petition for reconsideration of the FMVSS No. 141 final rule published 
December 14, 2016. NHTSA is proposing to remove the limit to the number 
of compliant sounds that a manufacturer may choose to install in a 
vehicle. Drivers would be able to select the sound they prefer from the 
set of sounds installed in the vehicle. NHTSA is also seeking comment 
on whether interested parties believe that the agency should establish 
a limit to the number of compliant sounds from which a driver may 
select that a manufacturer may choose to install in a vehicle.
    This document also makes technical changes.

DATES: Comments on this proposal must be received no later than 
November 1, 2019.

ADDRESSES: All comments and other information relating to this notice 
should refer to the docket number in the heading of this document and 
be submitted to: Administrator, National Highway Traffic Safety 
Administration, U.S. Department of Transportation, 1200 New Jersey 
Avenue SE, West Building, Washington, DC 20590.

FOR FURTHER INFORMATION CONTACT: You may contact Mr. Thomas Healy, 
NHTSA Office of the Chief Counsel, at 202-366-2992 (FAX: 202-366-3820) 
or Mr. Michael Pyne, NHTSA Office of Crash Avoidance Standards, at 202-
366-4171 (FAX: 202-493-2990).

SUPPLEMENTARY INFORMATION: NHTSA is proposing to amend FMVSS No. 141, 
Minimum Sound Requirements for Hybrid and Electric Vehicles (the 
``Quiet Vehicles'' final rule) to remove the current limitation of one 
sound per vehicle model. Under the proposal, there would not be a limit 
to the number of compliant sounds a manufacturer could install in a 
vehicle. NHTSA is also requesting comment on whether there should be a 
limit to the number of compliant sounds that a manufacturer can install 
in a vehicle and what that limit should be.
    Under FMVSS No. 141 currently, the HEV pedestrian alert sounds are 
allowed to vary with vehicle operating condition (stationary, reverse, 
10 km/h, 20 km/h, and 30 km/h), but only one sound per operating 
condition is allowed for all vehicles of the same model, model year, 
body type and trim level. This proposal responds to a petition for 
reconsideration of the FMVSS No. 141 final rule published on December 
14, 2016.\1\ In a joint petition \2\ submitted to NHTSA in January 
2017, the Alliance of Automobile Manufacturers (Alliance) and Global 
Automakers (Global), the two main automotive industry groups in the 
U.S. representing most light vehicle manufacturers, requested several 
amendments.\3\ One of the requested

[[Page 48867]]

amendments, addressed in this proposed rule, was that NHTSA modify 
section S5.5 of FMVSS No. 141 so that each HEV can be equipped with a 
suite of several pedestrian alert sounds for the driver to choose from 
rather than one sound. According to Alliance/Global, providing this 
choice is important for consumer acceptance of future HEVs that will 
have pedestrian alert sounds in compliance with FMVSS No. 141.
---------------------------------------------------------------------------

    \1\ Final Rule, Federal Motor Vehicle Safety Standards; Minimum 
Sound Requirements for Hybrid and Electric Vehicles [81 FR 90416], 
effective September 5, 2017; docket No. NHTSA-2016-0125.
    \2\ Docket item no. NHTSA-2018-0018-0004.
    \3\ NHTSA issued a final rule on February 26, 2018, to address 
the other requested actions in the Alliance/Global petition for 
reconsideration. In that petition response, the agency announced 
that it was planning to publish a notice proposing to allow driver-
selectable sounds.
---------------------------------------------------------------------------

    NHTSA promulgated FMVSS No. 141 pursuant to the Pedestrian Safety 
Enhancement Act (PSEA) of 2010.\4\ The PSEA included language that 
placed constraints on the multitude of different HEV pedestrian alert 
sounds that are possible. The PSEA stated NHTSA should allow 
manufacturers to provide each vehicle with one or more sounds at the 
time of manufacture. The PSEA further stated that NHTSA must require 
that vehicles of the same make and model produce the same sound or set 
of sounds, which would result in all similar vehicles having a similar 
sound in a given operating condition (forward, reverse, etc.). The PSEA 
did not, however, establish a specific limitation on the number of 
sounds emitted by vehicles subject to the final rule.
---------------------------------------------------------------------------

    \4\ Public Law 111-373, 124 Stat. 4086 (January 4, 2011).
---------------------------------------------------------------------------

    NHTSA implemented this PSEA limitation in the FMVSS No. 141 final 
rule \5\ under section S5.5 titled ``Sameness.'' This section states 
that vehicles of the same make, model, model year, and trim level must 
have the same pedestrian alert sound. The agency interpreted the PSEA 
``sameness'' language to allow vehicles to have different sounds for 
different operating modes, such as forward, reverse and stationary. The 
requirements as published in FMVSS No. 141 do not permit a vehicle to 
have multiple sounds from which the driver can choose. The agency 
discussed this in the preamble of the final rule.\6\
---------------------------------------------------------------------------

    \5\ The PSEA also included a restriction on disabling or 
altering of factory-equipped alert sounds. NHTSA implemented that 
PSEA restriction separately in paragraph S8 of FMVSS No. 141.
    \6\ See Final Rule, 81 FR 90416, at p. 90472.
---------------------------------------------------------------------------

    The automotive industry groups' petition showed they had a 
different view of the language of the PSEA regarding multiple sounds 
per vehicle. Because the original Notice of Proposed Rulemaking (NPRM) 
for FMVSS No. 141 did not contemplate allowing driver-selectable 
sounds, the agency is opening this issue for public comment before 
proceeding with an amendment of FMVSS No. 141.
    This notice also makes a technical change to section S6.7 of FMVSS 
No. 141 relating to ambient noise correction procedures. NHTSA has 
received several requests to clarify the procedural step in S6.7.3 for 
evaluation of ambient one-third octave bands in compliance tests. NHTSA 
is issuing a reworded paragraph S6.7.3 to specify more clearly the 
point at which the one-third octave bands should be computed during 
measurements of ambient noise.
    Lastly, in this notice NHTSA is correcting two dates in the FMVSS 
No. 141 phase-in reporting requirements in 49 CFR 585, Subpart N.
    This proposed rule is deregulatory in nature and is expected to 
generate benefits and cost savings in excess of costs. The proposed 
rule provides manufacturers with more flexibility and options in 
developing and installing sounds for their hybrid and electric 
vehicles. NHTSA believes it is reasonable to assume that manufacturers 
would not utilize the flexibilities provided by the proposal to develop 
and install additional selectable sound options unless the benefits 
exceed the costs to them. Likewise, NHTSA believes it is reasonable to 
assume that consumers would not pay more for vehicles with additional 
sound options unless the benefits to them exceed any additional cost of 
the vehicle.

Background

    The PSEA was enacted in January 2011 and mandated that NHTSA must 
establish a new motor vehicle safety standard applying to HEVs. The 
PSEA stated the new standard must ``establish performance requirements 
for an alert sound that allows blind and other pedestrians to 
reasonably detect a nearby electric or hybrid vehicle operating below 
the cross-over speed . . . .'' In section 3(2) of the PSEA, there is a 
provision addressing ``sameness'' of the required vehicle alert sounds. 
Section 3(2) states that HEVs must have ``within reasonable 
manufacturing tolerances, the same sound or set of sounds for all 
vehicles of the same make and model . . . .''
    Pursuant to the PSEA, NHTSA issued an NPRM \7\ in January 2013 and 
a final rule in December 2016, to create a new FMVSS setting minimum 
sound level requirements for the operation of HEVs at speeds up to 30 
km/h. The requirements in the final rule respond to the PSEA mandate by 
providing a level of vehicle sound that the blind and sighted 
pedestrians, as well as bicyclists, can use to detect the presence of 
these so-called ``quiet vehicles,'' thereby reducing the risk of low-
speed pedestrian and bicyclist crashes involving HEVs. The FMVSS 
applies to electric and hybrid-electric passenger cars, multi-purpose 
vehicles, light trucks, and buses with a GVWR of 10,000 pounds or less 
that can be operated in electric mode without an internal combustion 
engine (ICE). To comply with the standard, light vehicle manufacturers 
in most cases will equip vehicles with pedestrian alert systems that 
meet the minimum sound levels specified in the standard. These systems 
typically consist of one or more audio speakers, amplifiers, a control 
module, and software capable of generating the required sound. It is 
possible for a vehicle to meet some or all the minimum sound levels 
without added hardware if there is sufficient noise from other sources 
within the vehicle. For example, the sound emitted by a battery cooling 
system or a vehicle's tires at 30 km/h might satisfy the minimum 
specifications without added noise from an alert system.
---------------------------------------------------------------------------

    \7\ 78 FR 2798.
---------------------------------------------------------------------------

    After the final rule was published, NHTSA received timely petitions 
for reconsideration from three sources: The Auto Alliance in 
conjunction with Global Automakers (Alliance/Global), Nissan North 
America, Inc. (Nissan), and American Honda Motor Company, Inc. (Honda). 
Each of these petitioners requested changes to various aspects of the 
final rule. The requested changes included the phase-in schedule and 
compliance lead-time as well as other requirements of the new safety 
standard such as how much alert sound variation is allowed between 
vehicles of the same make and model. The petitions also asked for 
clarification of some technical aspects of the acoustic performance 
requirements and test procedures.
    Alliance/Global included in its petition a request for NHTSA to 
amend S5.5 of the new safety standard to explicitly allow automakers to 
equip their HEVs with multiple different sounds, rather than just one 
sound, for each operating condition as specified in the FMVSS No. 141 
final rule. NHTSA is responding to that petition request by proposing 
to amend FMVSS No. 141 to accommodate driver-selectable sounds. NHTSA 
is issuing this NPRM to solicit public comment on the proposed change.
    Specifically, NHTSA proposes amending Paragraph S5.5.1 to remove 
any limit on the number of sounds per vehicle make/model. NHTSA is also 
requesting comment from any interested parties on whether there should 
be a limit to the number of driver selectable sounds and what that 
limit should be.

[[Page 48868]]

Discussion

Sameness Requirement

    The ``Sameness'' provision appears in section 3(2) of the PSEA and 
states that the federal regulation created pursuant to the PSEA ``shall 
allow manufacturers to provide each vehicle with one or more sounds 
that comply with the motor vehicle safety standard at the time of 
manufacture.'' Section 3(2) further states that the regulation ``shall 
require manufacturers to provide, within reasonable manufacturing 
tolerances, the same sound or set of sounds for all vehicles of the 
same make and model.''
    NHTSA interpreted this section of the PSEA to mean that a 
manufacturer may choose to equip a vehicle with different sounds for 
different operating modes, including stationary, reverse, and forward 
at 10 km/h, 20 km/h, and 30 km/h.\8\ However, in the December 2016 
final rule, NHTSA did not interpret this language to mean vehicles can 
be equipped with more than one alert sound for a given operating 
condition and speed.
---------------------------------------------------------------------------

    \8\ See NHTSA NPRM [78 FR 2798], p. 2804.
---------------------------------------------------------------------------

    Consequently, NHTSA did not include any provision in either the 
NPRM or final rule allowing for more than a single alert sound per 
operating mode. Instead, FMVSS No. 141 requires that any two vehicles 
of the same make and model to which the standard applies must have the 
same alert sound when operating under the same test conditions and the 
same speed.\9\
---------------------------------------------------------------------------

    \9\ Section S5.5.1 of FMVSS No. 141, as published in December 
2016, allowed the alert sound to vary by model year as well as make 
and model (see 81 FR 90472). This was further amended on February 
26, 2018, to allow alert sounds to vary by trim level and body style 
within a make/model/model year (see 83 FR 8189).
---------------------------------------------------------------------------

Alliance/Global Petition

    In their January 2017 petition, Alliance/Global stated that NHTSA 
adopted an inflexible approach to ensuring sameness and did not account 
for specific statutory language in the PSEA that permits multiple alert 
sounds per vehicle. Specifically, Alliance/Global believe the words 
``one or more sounds'' in Section 3(2) of the PSEA provide this 
flexibility and that NHTSA's final rule was inconsistent with this. 
Alliance/Global stated that providing a selection of sounds is 
essential for customer acceptance of HEVs: ``Satisfying our customers 
is a primary concern for OEMs [Original Equipment Manufacturers]. Since 
`one size does not fit all' neither will one alert sound for a given 
make, model, trim level and model year satisfy all those consumers 
purchasing all these same vehicles.'' The petition also discussed 
comments submitted to the agency in February 2014 jointly by the 
Alliance, Global, the American Council of the Blind (ACB), and the 
National Federation of the Blind (NFB), in which the commenters, 
including the two advocate organizations, recognized the need to 
provide consumers with a reasonable number of driver-selectable sound 
choices for customer acceptance reasons.
    Alliance/Global submitted a follow-up letter \10\ dated March 1, 
2017, to supplement their petition. One aspect of the letter addressed 
the fact that the variety of alert sounds that manufacturers can create 
that comply with the safety standard is virtually unlimited due to the 
acoustic flexibility provided by the requirements in FMVSS No. 141. To 
address this concern, Alliance/Global stated that, in the event NHTSA 
amended FMVSS No. 141 to allow selectable sounds, they recommend a 
limit of five sounds per vehicle. They provided the following 
explanation: ``Because every additional driver-selectable choice of 
sound requires a separate certification test as well as a compliance 
test, the number of driver-selectable choices provided by manufacturers 
would naturally be limited for practical reasons. However, to address 
potential concerns that manufacturers might provide too many optional 
sounds, we recommend that the number of permitted driver-selectable 
sounds be limited to no more than five driver-selectable alert sounds 
for any make, model, trim level, model year vehicle.''
---------------------------------------------------------------------------

    \10\ Docket No. NHTSA-2016-0125-0016.
---------------------------------------------------------------------------

    The Alliance and Global's January 2017 petition also discussed 
possible implications of paragraph S8 of FMVSS No. 141 regarding a 
selectable-sounds provision. Paragraph S8 implements part of Section 
3(2) of the PSEA by prohibiting alteration of a factory-installed sound 
except in case of a vehicle repair or recall.\11\ The Alliance/Global 
petition states, ``The ability to permit customers to select different 
compliant sounds from a set of driver-selectable compliant sounds does 
not violate the PSEA restrictions against disabling, altering, 
replacing, or modifying the sound or set of sounds. Specifically, as 
long as the customer is selecting a sound that is among the `set of 
sounds' provided by the manufacturer when the car is new, then the 
driver is not modifying the `set' by selecting sounds provided within 
the `set.' ''
---------------------------------------------------------------------------

    \11\ The Alliance/Global petition requested a small change to 
paragraph S8 of FMVSS No. 141 so that vehicle repairs to a module 
that controls both the pedestrian alert system and other vehicle 
systems would not violate the prohibition on alterations to the 
alert system. NHTSA granted their request on this point in the 
agency's February 2018 petition response by adopting minor edits to 
paragraph S8 as suggested by Alliance/Global.
---------------------------------------------------------------------------

NHTSA Proposal and Request for Comments

    After considering the Alliance/Global petition, and recognizing 
that the language of the PSEA regarding sameness of sounds among 
vehicles of the same make and model is subject to more than one 
interpretation, and also that consumer preferences for vehicle alert 
sounds will depend on subjective factors, NHTSA has decided to propose 
amending FMVSS No. 141 to allow an unlimited number of pedestrian alert 
sounds per vehicle for any operating condition. (As previously stated, 
the different operating conditions are when the vehicle is stationary, 
in reverse, or moving forward at speeds up to 30 km/h.)
    This proposal would also improve international harmonization by 
aligning FMVSS No. 141 more closely with international regulations, 
particularly United Nations ECE Regulation No. 138 for Audible Vehicle 
Alerting Systems, which states ``a vehicle manufacturer may define 
alternative sounds which can be selected by the driver.'' The ECE 
regulation does not specify a particular limit on the number of 
alternative sounds that may be provided.
    The agency believes that allowing for an additional number of 
sounds will have no effect on safety, since all sounds would still need 
to comply with the standard. NHTSA notes that the Alliance/Global 
petition recommended up to five sounds per operating condition. The 
agency requests comment on this suggestion and any other appropriate 
limit.
    In summary, NHTSA is seeking comment from all interested parties on 
amending the ``Sameness'' requirement, section S5.5.1 of FMVSS No. 141, 
which currently allows only one sound, to allow multiple sounds per 
operating condition for each model, model year, trim, and body style of 
HEV. Specifically, NHTSA requests comment and supporting information on 
any safety implications, compliance issues, consumer-acceptance 
factors, cost issues, or other possible alternatives that would 
accompany allowing an unlimited number of compliant driver-selectable 
sounds in FMVSS No. 141.
    In particular, NHTSA seeks comment on the potential safety issues 
related to HEV recognition by pedestrians if a multitude of new 
compliant driver-

[[Page 48869]]

selectable sounds are available, and the extent to which having an 
unlimited number of sounds would lead to the potential for a 
pedestrian's inability to identify the sounds as a motor vehicle.
    As to the remaining aspects of the Alliance/Global petition, NHTSA 
is not proposing any change to paragraph S8 of FMVSS No. 141 and 
believes amending S5.5.1 as proposed in this notice will fully address 
the Alliance/Global petition on driver-selectable sounds. The 
requirements in S8 still would apply to the set of selectable sounds 
provided by the OEM, i.e., aftermarket modification of the set of 
sounds would not be permitted except in allowable circumstances 
specified in section S8, such as vehicle repairs and recalls.

Technical Clarification and Correction

    NHTSA recently became aware that the procedure in FMVSS No. 141 for 
evaluating ambient noise during compliance tests is unclear. The 
Alliance and Global raised this issue in an April 2018 letter along 
with several other FMVSS No. 141 technical concerns.\12\ The ambient 
noise correction procedure at issue is in section S6.7.3.
---------------------------------------------------------------------------

    \12\ See Docket item no. NHTSA-2018-0018-0004.
---------------------------------------------------------------------------

    This paragraph indicates that the one-third octave band levels of 
the ambient noise recording that are used for correction of vehicle 
measurements are the individual minimum levels in each one-third octave 
at any point in time over the 60-seconds of recorded ambient noise. 
This incorrectly implies that the levels of different one-third octave 
bands may be evaluated at different times. This was not NHTSA's 
intention. The correct method intended by the agency is to evaluate 
ambient levels of all 13 one-third octave bands at the same point in 
time. The point in time at which ambient one-third octave bands are 
supposed to be evaluated is the unique point during the 60 seconds when 
the overall sound pressure level of the ambient is at a minimum, as 
identified in S6.7.2, the preceding step in the ambient correction 
procedure.
    To resolve this, NHTSA is proposing to amend paragraph S6.7.3 to 
more clearly state the intended method of evaluating one-third octave 
bands for ambient correction. A proposed rewording of section S6.7.3 
that would implement this change is included at the end of this 
document. The agency invites all interested parties to comment on this 
change.
    Additionally, NHTSA has become aware of a minor correction that is 
needed in the phase-in reporting requirements of FMVSS No. 141. The 
FMVSS No. 141 final rule published in December 2016 required vehicle 
manufacturers to report on their production of compliant HEVs during a 
one-year phase-in period. (This kind of reporting requirement is 
standard practice for NHTSA rules that include a phase-in period.) The 
reporting requirements and associated due dates for phase in of 
compliance with FMVSS No. 141 are contained in 49 CFR 585, Subpart N. 
NHTSA has determined that the December 2016 rule amending Part 585, 
Subpart N, states in two places, ``the production year ending August 
31, 2018'' instead of ``the production year ending August 31, 2019.'' 
When NHTSA granted a petition to extend the FMVSS No. 141 phase-in and 
compliance deadlines by one year,\13\ the reporting dates in Part 585, 
Subpart N, were all adjusted by adding one year. However, because those 
two dates were stated incorrectly in the original final rule, the 
adjusted dates also were off by one year. In this notice, NHTSA is 
making the necessary changes to 49 CFR 585, Subpart N, to specify that 
phase-in reporting applies to the production year ending August 31, 
2020. The corrected regulatory text, is included at the end of this 
document.

Rulemaking Analyses and Notices

A. Executive Order 12866, Executive Order 13563, and DOT Regulatory 
Policies and Procedures

    NHTSA has considered the impact of this rulemaking action under 
Executive Order 12866, Executive Order 13563, and the Department of 
Transportation Order 2100.6, ``Policies and Procedures for 
Rulemakings.'' This rulemaking is not considered significant and was 
not reviewed by the Office of Management and Budget under E.O. 12866, 
``Regulatory Planning and Review.'' Given the minimal impact of the 
rule, in accordance with the Department's regulatory policies and 
procedures, we have not prepared a full regulatory evaluation.\14\ The 
agency has further determined that the impact of this proposed rule is 
so minimal that the preparation of a full regulatory evaluation is not 
required.
---------------------------------------------------------------------------

    \14\ Department of Transportation, Adoption of Regulatory 
Policies and Procedures, 44 FR 11034 (Feb. 26, 1979).
---------------------------------------------------------------------------

    This proposed rule responding to a petition for reconsideration 
does not add any cost, as it would afford manufacturers additional 
flexibility in designing their vehicles to meet customer acceptance 
goals. It would not add new requirements or increase design or 
production burden for vehicle manufacturers.
    This proposal, if adopted, would remove a final-rule restriction on 
vehicle design that auto manufacturers in the U.S. have sought to 
remove. This amendment also would give manufacturers of hybrid and 
electric vehicles greater flexibility in marketing those vehicles to 
consumers and make vehicles potentially more appealing to consumers by 
providing customer choice in selecting vehicle sounds.
    The benefits and cost savings of this proposed rule are expected to 
exceed any increase in costs to manufacturers if they choose to create 
additional sounds. The proposal would allow manufacturers to equip 
vehicles with additional sounds but would not require it. If this 
proposal is finalized, a manufacturer would still be able to comply 
with FMVSS No. 141 by equipping a vehicle with a single sound.
    The proposed rule provides manufacturers with more flexibility and 
options in developing and installing sounds for their hybrid and 
electric vehicles. NHTSA believes it is reasonable to assume that 
manufacturers would not utilize the flexibilities provided by the 
proposal to develop and install additional selectable sounds unless the 
benefits to them exceed the costs to them. Likewise, NHTSA believes it 
is reasonable to assume that consumers would not purchase vehicles with 
additional sounds unless the benefits to them exceed any additional 
cost of the vehicle. At the same time, the proposal would not have any 
effect on safety, as all sounds would still need to comply with the 
standard.

B. 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 rulemaking for any proposed 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)). No 
regulatory flexibility analysis is required if the head of an agency 
certifies the rule would not have a significant economic impact on a 
substantial number of small entities. SBREFA amended the Regulatory

[[Page 48870]]

Flexibility Act to require Federal agencies to provide a statement of 
the factual basis for certifying that a rule would not have a 
significant economic impact on a substantial number of small entities.
    NHTSA has considered the effects of this proposed rule under the 
Regulatory Flexibility Act. This proposed rule would directly impact 
manufacturers of hybrid and electric vehicles. Most manufacturers 
affected by this proposed rule are not small businesses. To the extent 
any manufacturers of hybrid or electric vehicles are small businesses, 
we do not believe this proposed rule would have a significant economic 
impact on any small businesses as this proposed rule would not impose 
any costs on manufacturers but would instead increase flexibility for 
vehicle manufacturers.

C. Executive Order 13132 (Federalism)

    NHTSA has examined today's proposed rule 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 would not have sufficient federalism 
implications to warrant consultation with State and local officials or 
the preparation of a federalism summary impact statement. The proposed 
rule would 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 Order 13132 and 12988, NHTSA has considered 
whether this rulemaking action 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 today's 
proposed rule and finds that this rule, like many NHTSA rules, 
prescribes only a minimum safety standard. As such, NHTSA does not 
intend that this rule preempt State tort law that would effectively 
impose a higher standard on motor vehicle manufacturers than that 
established by today's rule. 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.

D. Executive Order 13771 (Regulatory Reform)

    NHTSA has reviewed this proposed rule for compliance with E.O. 
13771 (``Reducing Regulation and Controlling Regulatory Costs''), which 
requires Federal agencies to offset the number and cost of new 
regulations through the repeal, revocation, or revision of existing 
regulations. As provided in OMB Memorandum M-17-21 (``Implementing E.O. 
13771''), a ``regulatory action'' subject to E.O. 13771 is a 
significant regulatory action as defined in section 3(f) of E.O. 12866 
that has been finalized and that imposes total costs greater than zero. 
For the reasons identified in the previous sections, this proposed rule 
is not a significant regulatory action under E.O. 12866.
    Furthermore, this proposal is a ``deregulatory action'' under E.O. 
13771 because, as discussed above, it would reduce regulatory burden on 
industry by allowing design flexibility by giving manufacturers the 
option to use selectable sounds. Also, it would improve international 
harmonization by aligning more closely with international regulations, 
particularly United Nations ECE Regulation No. 138 for Audible Vehicle 
Alerting Systems.

E. Executive Order 12988 (Civil Justice Reform)

    With respect to the review of the promulgation of a new regulation, 
section 3(b) of Executive Order 12988, ``Civil Justice Reform'' (61 FR 
4729; Feb. 7, 1996), requires that Executive agencies make every 
reasonable effort to ensure that the regulation: (1) Clearly specifies 
the preemptive effect; (2) clearly specifies the effect on existing 
Federal law or regulation; (3) provides a clear legal standard for 
affected conduct, while promoting simplification and burden reduction; 
(4) clearly specifies the retroactive effect, if any; (5) specifies 
whether administrative proceedings are to be required before parties 
file suit in court; (6) adequately defines key terms; and (7) addresses 
other important issues affecting clarity and general draftsmanship 
under any guidelines issued by the Attorney General. This document is 
consistent with that requirement.
    Pursuant to this Order, NHTSA notes that the issue of preemption is 
discussed separately in this notice. NHTSA notes further that there is 
no requirement that individuals submit a petition for reconsideration 
or pursue other administrative proceedings before they may file suit in 
court.

F. Protection of Children From Environmental Health and Safety Risks

    Executive Order 13045, ``Protection of Children from Environmental 
Health and Safety Risks'' (62 FR 19855, April 23, 1997), applies to any 
rule that: (1)

[[Page 48871]]

Is determined to be ``economically significant'' as defined under 
Executive Order 12866, and (2) concerns an environmental, health, or 
safety risk that the agency has reason to believe may have a 
disproportionate effect on children. If the regulatory action meets 
both criteria, the agency must evaluate the environmental health or 
safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the agency.
    This notice is part of a rulemaking that is not expected to have a 
disproportionate health or safety impact on children. Consequently, no 
further analysis is required under Executive Order 13045.

G. 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. There is not 
any new information collection requirement associated with this 
proposed rule.

H. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act (NTTAA) requires NHTSA to evaluate and use existing voluntary 
consensus standards in its regulatory activities unless doing so would 
be inconsistent with applicable law (e.g., the statutory provisions 
regarding NHTSA's vehicle safety authority) or otherwise impractical. 
Voluntary consensus standards are technical standards developed or 
adopted by voluntary consensus standards bodies. Technical standards 
are defined by the NTTAA as ``performance-based or design-specific 
technical specification and related management systems practices.'' 
They pertain to ``products and processes, such as size, strength, or 
technical performance of a product, process or material.'' Examples of 
organizations generally regarded as voluntary consensus standards 
bodies include ASTM International, the SAE International, and the 
American National Standards Institute. If NHTSA does not use available 
and potentially applicable voluntary consensus standards, we are 
required by the Act to provide Congress, through OMB, an explanation of 
the reasons for not using such standards.
    There are no voluntary consensus standards developed by voluntary 
consensus standards bodies pertaining to this proposed rule.

I. 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 NHTSA 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.
    This proposed rule would not result in any expenditure by State, 
local, or tribal governments or the private sector of more than $100 
million, adjusted for inflation.

J. National Environmental Policy Act

    NHTSA analyzed the original FMVSS No. 141 final rule for the 
purposes of the National Environmental Policy Act. The agency 
determined that implementation of that rule would not have any 
significant impact on the quality of the human environment.\15\
---------------------------------------------------------------------------

    \15\ Docket item no. NHTSA-2016-0125-0009, https://www.regulations.gov/document?D=NHTSA-2016-0125-0009.
---------------------------------------------------------------------------

    The rulemaking action in this notice would amend the FMVSS No. 141 
final rule in a way that would not change the impact for the purposes 
of the National Environmental Policy Act. Therefore, the agency has 
determined that implementation of this action would not have any 
significant impact on the quality of the human environment.

K. 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.

L. Privacy Act
