II. Executive Summary 
A. Purpose and Summary of the 
Regulatory Action 
Section 393.60(e)(1)(i) of the FMCSRs 
prohibits obstruction of the driver’s field of view by devices mounted at the top of the windshield. Antennas and similar devices must not be mounted more than 152 mm (6 inches) below the upper edge of the windshield, and must be outside the driver’s sight lines to the road and highway signs and signals. 
Section 393.60(e)(1)(i) does not apply 
to vehicle safety technologies, as defined in § 393.5, that include ‘‘a fleet- related incident management system, performance or behavior management system, speed management system, forward collision warning or mitigation system, active cruise control system, and transponder.’’ Section 393.60(e)(1)(ii) requires devices with vehicle safety technologies to be mounted (1) not more than 100 mm (4 inches) below the upper edge of the area swept by the windshield wipers, or (2) not more than 175 mm (7 inches) above the lower edge of the area swept by the windshield wipers, and (3) outside the driver’s sight lines to the road and highway signs and signals. 
Specifically, the Agency proposes to 
modify § 393.60(e)(1)(ii) to increase from 100 mm (4 inches) to 216 mm (8.5 inches) the distance below the upper edge of the area swept by the windshield wipers within which vehicle safety technologies may be mounted. The other parameters would remain unchanged. The Agency believes the potential economic impact of these changes is negligible. The proposed amendments do not impose new or more stringent requirements, but simply codify the temporary exemptions granted pursuant to 49 CFR part 381 that allow the use of the devices/ technologies in locations that would previously have been a violation of § 393.60(e)(1). More importantly, the amendments do not mandate the use of any devices/technologies, but simply permit their voluntary use while mounted in a location that maximizes their effectiveness without impairing operational safety. 
B. Costs and Benefits 
The Agency expects that if a final rule 
is adopted consistent with this NPRM, 
it would generate cost savings for both industry and the Federal Government by reducing the overall time burden associated with the exemption request and approval process associated with 49 U.S.C. 31315 and the implementing regulations under 49 CFR part 381. The Agency estimates this NPRM would result in total annualized cost savings of $12,184 and $10,705 at 3 percent and 7 percent discount rates, respectively.

IV. Legal Basis for the Rulemaking 
This NPRM is based on the authority 
of the Motor Carrier Act, 1935 [1935 Act], the Motor Carrier Safety Act of 1984 [1984 Act], and the Fixing America’s Surface Transportation (FAST) Act. 
The 1935 Act, as amended, provides 
that ‘‘[t]he Secretary of Transportation may prescribe requirements for—(1) qualifications and maximum hours of service of employees of, and safety of operation and equipment of, a motor carrier; and (2) qualifications and maximum hours-of-service of employees of, and standards of equipment of, a motor private carrier, when needed to promote safety of operation.’’ [49 U.S.C. 31502(b)]. 
The 1984 Act provides concurrent 
authority to regulate drivers, motor carriers, and vehicle equipment. It requires the Secretary to ‘‘prescribe regulations on commercial motor vehicle safety. The regulations shall prescribe minimum safety standards for commercial motor vehicles. At a minimum, the regulations shall ensure that—(1) commercial motor vehicles are maintained, equipped, loaded, and operated safely; (2) the responsibilities imposed on operators of commercial motor vehicles do not impair their ability to operate the vehicles safely; (3) the physical condition of operators of commercial motor vehicles is adequate to enable them to operate vehicles safely . . . ; (4) the operation of commercial motor vehicles does not have a deleterious effect on the physical condition of the operators; and (5) an operator of a commercial motor vehicle is not coerced by a motor carrier, shipper, receiver, or transportation intermediary to operate a commercial motor vehicle in violation of a 
regulation promulgated under this section, or chapter 51 or chapter 313 of this title.’’ [49 U.S.C. 31136(a)]. 
Section 5301 of the FAST Act directs 
FMCSA to exempt voluntary mounting of a vehicle safety technology on a windshield if that technology is likely to achieve a level of safety that is equivalent to or greater than the level of safety that would be achieved without the exemption [Pub. L. 114–94, 129 Stat. 1312, 1543, Dec. 4, 2015]. Section 5301(c) also specifies that any regulatory exemption for windshield- mounted technologies in effect on the date of enactment of the FAST Act 
‘‘shall be considered likely to achieve a level of safety that is equivalent to or greater than the level of safety that would be achieved absent an exemption . . . .’’ 
This NPRM is based in part on the 
1935 Act, which allows the Agency to regulate the ‘‘safety of operation and equipment’’ of a motor carrier and the ‘‘standards of equipment’’ of a motor private carrier. The requirements of 49 U.S.C. 31136 (a)(1), (2), and (4) of the 1984 Act are also applicable to this rulemaking action. The Agency proposes to amend 49 CFR part 393 to allow certain safety equipment to be mounted within the area of the windshield swept by the windshield wipers. The Agency believes that these changes will be welcomed by motor carriers and drivers alike and that coercion to violate these revised provisions, which is prohibited by § 31136(a)(5), will not be an issue. The NPRM does not involve the physical condition of drivers under § 31136(a)(3). 
This NPRM rests in part on the intent 
of Congress expressed in section 5301 of the FAST Act to exempt safety equipment mounted within the swept 
area of windshields, provided such devices do not degrade operational safety. 
FMCSA must consider the ‘‘costs and 
benefits’’ of any proposal before promulgating regulations (49 U.S.C. 31136(c)(2)(A), 31502(d)). 
V. Background 
The fundamental purpose of 49 CFR 
part 393, ‘‘Parts and Accessories 
Necessary for Safe Operation,’’ is to ensure that no employer shall operate a CMV, or cause or permit it to be operated, unless it is equipped in accordance with the requirements and specifications of this part. However, nothing contained in part 393 shall be construed to prohibit the use of additional equipment and accessories, not inconsistent with or prohibited by part 393, provided such equipment and accessories do not decrease the safety of operation of the CMVs on which they are used (§ 393.3). 
Section 5301 of the FAST Act 
directed the Agency to amend the FMCSRs to allow devices to be mounted on the windshield that utilize ‘‘vehicle safety technology,’’ as defined in the Act. In addition, section 5301 stated that all windshield-mounted devices/ technologies with a limited 2-year exemption in effect on the date of enactment were considered to meet the safety standard required for the initial exemption, i.e., achieving a level of 
safety equivalent to, or greater than, the level that would be achieved absent the exemption. On September 23, 2016, FMCSA published a final rule titled ‘‘Parts and Accessories Necessary for Safe Operation; Windshield-Mounted Technologies,’’ (81 FR 65568), which amended the FMCSRs to allow the voluntary mounting of certain devices on the interior of the windshields of CMVs, including placement within the area that is swept by the windshield wipers (49 CFR 393.60(e)(1)). 
A. Temporary Exemptions 
Since the Agency amended § 393.60 
in 2016, FMCSA has granted a number 
of temporary exemptions for the placement of safety technologies and devices that require a clear forward- facing visual field for proper operation. These devices either need to be mounted within the swept area of the windshield, or should be mounted on the windshield so that the driver does not have to take his/her eyes off the road to look at the device, such as Global Positioning System (GPS) displays. 
On August 3, 2017 (82 FR 36182), 
FMCSA granted Hino Motors a 5-year exemption from 49 CFR 393.60(e)(1) on behalf of motor carriers to operate CMVs manufactured by Hino equipped with Automated Emergency Braking/Lane Departure Warning system cameras mounted in the approximate center of the windshield such that the bottom edge of the camera is not more than 7 inches below the upper edge of the windshield and outside the driver’s sight lines to all mirrors, highway signs, signals, and view of the road ahead. 
On January 31, 2018 (83 FR 4543), 
FMCSA granted DTNA a 5-year exemption from 49 CFR 393.60(e)(1) on behalf of CMVs manufactured by DTNA equipped with the Attention Assist and Lane Departure Warning system camera mounted in the approximate center of the windshield such that the bottom edge of the camera is not more than 8.5 inches below the top of the area swept by the windshield wipers and outside the driver’s sight lines to all mirrors, highway signs, signals, and view of the road ahead. 
On August 22, 2018 (83 FR 42552), 
FMCSA granted Traditional Trucking Corporation a 5-year exemption from 49 CFR 393.60(e)(1) on behalf of motor carriers to operate CMVs equipped with GPS devices mounted (1) not more than 100 mm (4 inches) below the upper edge of the area swept by the windshield wipers; or (2) not more than 175 mm (7 inches) above the lower edge of the area swept by the windshield wipers; and (3) outside the driver’s sight lines to the road and highway signs and signals.

B. Petition for Rulemaking 
On March 10, 2019, DTNA petitioned 
the Agency to initiate a rulemaking to 
amend 49 CFR 393.60, ‘‘Parts and Accessories Necessary for Safe Operation, Glazing in Specified Openings.’’
1DTNA sought a revision to 
49 CFR 393.60(e)(l)(ii)(A) to allow safety-enhancing technologies to be placed on the interior of the windshield within 8.5 inches below the upper edge of the area swept by the windshield wipers, which would make permanent the exemption the Agency granted DTNA in 2018. The petition also asked FMCSA to expand the definition of vehicle safety technology, found at § 393.5, to include additional items of equipment that are intended to promote driver, occupant, and roadway safety. These items included braking warning systems, braking assist systems, automatic emergency braking, driver camera system, attention assist warning, and traffic sign recognition. 
VI. Discussion of Proposed Rulemaking 
FMCSA proposes to amend 
§ 393.60(e) to allow certain additional 
vehicle safety technologies to be mounted on the interior of the windshield of a CMV, within a defined portion of the swept area of the windshield. FMCSA is proposing to modify the definition of vehicle safety technology in § 393.5 of the FMCSRs, to add technologies that had been granted 
temporary exemptions from § 393.60(e) since the 2016 final rule. Consistent with the terms and conditions outlined in the various temporary exemptions currently in effect, FMCSA proposes to require devices that must be mounted within the area swept by the windshield wipers to be located (1) not more than 216 mm (8.5 inches) below the upper edge, and (2) not more than 175 mm (7 inches) above the lower edge of the swept area. Additionally, and consistent with the existing regulation and the terms and conditions of the temporary exemptions, the devices would have to be located outside the driver’s sight lines to the road and highway signs and signals. 
Similar to the 2016 amendments to 
§ 393.60, this NPRM proposes to update the FMCSRs in response to the development and proliferation of devices that utilize new and innovative vehicle safety technologies that did not exist at the time the previous requirements were adopted. If finalized, this NPRM rule would add GPS to the list of vehicle safety technologies even though the GPS display does not require a clear forward-facing visual field through the windshield. As discussed in the Traditional Trucking Corporation temporary exemption, GPS devices cannot be mounted to the ‘‘face’’ of the CMVs control panel as that area is covered with controls and displays necessary for the operation of the CMV. The GPS device can be located on top of the dash, which in many cases leaves the GPS in the same visual field as if the GPS were located on the windshield in the lower allowable area. Mounting the GPS lower on the dash would take the driver’s eyes farther from the road. The size of GPS display units is approximately the same size as the currently allowed vehicle safety technologies in the driver’s visual field. These devices/technologies have been 
proven to improve safety and vehicle operations. 
The first temporary exemption from 
§ 393.60(e)(1) was granted in March 2009, and FMCSA has over 12 years of real-world experience overseeing motor carriers operating CMVs using devices mounted on the interior of the windshield and marginally within the area swept by the windshield wipers. FMCSA is unaware of any crashes during that time attributed to the location of such devices. 
To assist in development of the 
proposed regulatory revisions, the Agency specifically requests responses to the following questions: 
1. Does the definition of vehicle safety 
technology need to be expanded further

and/or multifunction devices such as electronic logging devices that incorporate technologies such as GPS that either require placement in the approximate middle of the CMV windshield or would benefit driver safety by not diverting the CMV driver’s eyes from the road and would be subject to the positioning requirements of § 393.60(e)(1)? 
2. Would the proposed position of 
allowable vehicle safety technologies (not more than 8.5 inches below the upper and 7 inches above the lower edge of the swept area of the windshield) be sufficient for current and developing devices? 
VII. Section-by-Section Analysis 
This section-by-section analysis 
describes the proposed changes in 
numerical order. 
A. Section 393.5 Definitions 
The definition for vehicle safety 
technology would be revised by adding 
more examples of vehicle safety 
technologies to those listed in the definition. 
B. Section 393.60 Glazing in Specified 
Openings 
This section would be revised by 
replacing ‘‘100 mm (4 inches)’’ with ‘‘216 mm (8.5 inches)’’ in paragraph (e)(1)(ii)(A). Additionally, a new paragraph (e)(1)(ii)(C) would be added to read ‘‘Outside the driver’s sight lines to the road and highway signs and signals.’’ 
VIII. Regulatory Analyses A. Executive Order (E.O.) 12866 
(Regulatory Planning and Review), E.O. 13563 (Improving Regulation and Regulatory Review), and DOT Regulatory Policies and Procedures 
FMCSA has considered the impact of 
this notice of proposed rulemaking under E.O. 12866 (58 FR 51735, Oct. 4, 1993), Regulatory Planning and Review, E.O. 13563 (76 FR 3821, Jan. 21, 2011), Improving Regulation and Regulatory Review, and DOT’s regulatory policies and procedures. OIRA determined that this notice of proposed rulemaking is not a significant regulatory action under section 3(f) of E.O. 12866, as supplemented by E.O. 13563, and does not require an assessment of potential costs and benefits under section 6(a)(3) of that Order. Accordingly, OMB has not 
reviewed it under these Orders. 
Additionally, this NPRM supports 
Executive Order 13859 which states that ‘‘the policy of the United States Government is to sustain and enhance the scientific, technological, and economic leadership position of the United States in AI [artificial intelligence].’’
2The deployment of AI 
holds the promise to improve efficiency, effectiveness, safety, fairness, welfare, transparency, and other economic and social goals, and America’s continued status as a global leader in AI development is important to preserving our economic and national security. The importance of developing and deploying AI requires a regulatory approach that fosters innovation and growth and engenders trust, while protecting core American values, through both regulatory and non-regulatory actions and reducing unnecessary barriers to the development and deployment of AI. To support innovation and growth in the technological sector of CMV safety, FMCSA is issuing this NPRM as a response to a rulemaking petition from DTNA.

Baseline for the Analysis 
The mounting of devices on the 
interior of the windshield within the area swept by the windshield wipers is prohibited under 49 CFR 393.60(e), unless they are vehicle safety technologies. FMCSA has authority under 49 U.S.C. 31315(b) to grant exemptions from certain parts of the FMCSRs. FMCSA must publish a notice of each exemption request in the Federal Register (49 CFR 381.315(a)). The Agency must provide the public an opportunity to inspect the information relevant to the application, including any safety analyses that have been conducted. The Agency must also provide an opportunity for public comment on the request. FMCSA notes that the burden associated with preparing an exemption request is not included in a currently approved information collection request (ICR), and is pursuing completion of that ICR outside of this rulemaking. As originally enacted, 49 U.S.C. 
31315(b) allowed an exemption from a regulation (and a renewal) for no longer than 2 years from its approval date. Section 5206(a)(3) of the FAST Act (Pub. L. 114–94, 129 Stat. 1312, 1534– 1535 Dec. 4, 2015) amended section 31315(b) to allow an exemption to be granted for no longer than 5 years and to be renewed, upon request, for subsequent periods no longer than 5 years. 49 CFR 381.300 (b) 
Section 393.60(e)(1)(i) of the FMCSRs 
prohibits the obstruction of the driver’s field of view by devices mounted on the interior of the windshield. Antennas and similar devices must not be mounted more than 152 mm (6 inches) below the upper edge of the windshield, and outside the driver’s sight lines to the road and highway signs and signals. Section 393.60(e)(1)(i) does not apply to vehicle safety technologies, as defined in 49 CFR 390.5, including ‘‘a fleet- related incident management system, performance or behavior management system, speed management system, lane departure warning system, forward collision warning or mitigation system, active cruise control system, and transponder.’’ Section 393.60(e)(1)(ii) requires devices with vehicle safety technologies to be mounted (1) not more than 100 mm (4 inches) below the upper edge of the area swept by the windshield wipers, or (2) not more than 175 mm (7 inches) above the lower edge of the area swept by the windshield wipers, and outside the driver’s sight lines to the road and highway signs and signals. 
This NPRM proposes revisions to 49 
CFR 393.60 to expand the area where vehicle safety technologies (e.g., lane 
departure warning systems, forward collision warning and mitigation systems utilizing automated emergency braking, enhanced driver performance and behavior management and coaching systems) could be installed on the interior of windshields of CMVs. The NPRM, if finalized consistent with the terms proposed, would generate cost savings for both industry and government and is anticipated to achieve a level of safety equivalent to, or greater than, the level that would be achieved by the current regulation.

affected population, costs, cost savings, and benefits of this NPRM.

5We calculate the load factor for wages by 
dividing total compensation by wages and salaries. 
For this analysis, we used BLS’ ECEC/Management, professional, and related occupations. Using December 2019 data, we divided the total compensation amount of $60.83 by the wage and salary amount of $42.33 to get the load factor of 1.44 ($60.83 divided by $42.33). This data is found in table 9 of the ECEC Historical Listing. https://www.bls.gov/web/ecec/ececqrtn.pdf.

Cost, Cost Savings & Benefits 
This NPRM proposes two changes to 
the Parts and Accessories Necessary for 
Safe Operation regulations in 49 CFR part 393, subpart A and subpart D. 
Under the existing § 393.5 definitions, 
vehicle safety technology includes a fleet-related incident management system, performance or behavior management system, speed management system, lane departure warning system, forward collision warning or mitigation system, active cruise control system, and transponder. Under the proposed rulemaking § 393.5 definitions would now also include braking warning systems, braking assist systems, automatic emergency braking, driver camera systems, attention assist warning, Global Positioning Systems and traffic sign recognition. Vehicle safety technology includes systems and devices that contain cameras, lidar, radar, sensors and/or video. 
As a result of the proposed change, 
there would be new examples of vehicle safety technology devices and systems which would better accommodate the vehicle manufacturer advancements in the field of driver assistance technologies. The proposed change would have no cost. There would be benefits accrued through improved safety performance of CMVs via fatality, injury, and property damage prevention. For example, lane departure warning systems are anticipated to prevent accidents involving striking a car in an adjoining lane, which could either involve ‘‘sideswiping’’ a vehicle traveling in the same direction or hitting a vehicle traveling in the opposite 
direction, and rollovers, which often occur when a vehicle leaves the road. Additionally, automatic Emergency Braking systems engage dynamic brake support or crash-imminent braking to potentially save lives and reduce moderate and less severe rear-end crashes. 
With regards to the existing § 393.60, 
(e)(1)(ii), Paragraph (e)(1)(i) of this section does not apply to vehicle safety technologies, as defined in § 393.5, that are mounted on the interior of a windshield. Devices with vehicle safety technologies must be mounted outside the driver’s sight lines to the road and to highway signs and signals, and: 
•Not more than 100 mm (4 inches) 
below the upper edge of the area swept by the windshield wipers. 
•Not more than 175 mm (7 inches) 
above the lower edge of the area swept by the windshield wipers. 
Under the proposed change to 
§ 393.60, (e)(1)(ii), Paragraph (e)(1)(i) of this section does not apply to vehicle safety technologies, as defined in § 393.5, that are mounted on the interior of a windshield. Devices with vehicle safety technologies must be mounted outside the driver’s sight lines to the road and to highway signs and signals, and: 
•Not more than 216 mm (8.5 inches) 
below the upper edge of the area swept by the windshield wipers; or 
•Not more than 175 mm (7 inches) 
above the lower edge of the area swept by the windshield wipers; and 
•Outside the driver’s sight lines to 
the road and highway signs and signals. 
This proposed change would expand 
the area available for mounting vehicle safety technologies on the interior of a windshield. The proposed change would have no cost but would result in an annualized cost savings from reduced exemption application and approval process. The cost savings are estimated to be $12,184 and $10,705 at 3 percent and 7 percent discount rates. Wage Rates 
For this analysis, we calculated 
private sector wages using 2019 wage 
data from the U.S. Bureau of Labor Statistics (BLS) Occupational Employment Statistics for the Management of Companies and Enterprises (North American Industry Classification System 551100). We used median hourly wage for Standard Occupational Classification Code 11– 2021—Marketing Managers which is $65.79.
4 
We added a load factor to the industry 
wages for Marketing Managers using 
December 2019 wage and total compensation data from the BLS Employer Costs for Employee Compensation (ECEC) survey, which accounts for employee benefits. This load factor represents the total benefits as a percentage of total salary.
5We 
multiply the median hourly wage by the load factor to get the full loaded wage of $94.74. 
We utilize Federal Government 
employee wage rates based on the Office of Personnel Management (OPM) 2019 General Schedule (GS) pay for the DC– MD–VA–WV–PA locality for a GS–15 grade.

Administrator at the Senior Executive Service level is equivalent to a GS–15 grade for the purpose of this analysis. 12Loaded Hourly Wage × Number of Hours × 
Average number of exemptions x Personnel ($93.86 
× 12 × 3 × 3). hourly wage for a GS–15 Step 1 grade 
to be $66.05.7 
OMB publishes an object class 
analysis of the budget of the U.S. Government.
8The object class provides 
the actual values that, in 2019, DOT spent $5,931 million in full-time permanent employee compensation and $2,497 million in civilian employee benefits. Based on this, FMCSA estimates a fringe benefit rate of 42.10 percent (2,497/5,931) for FMCSA personnel or $27.81 ($66.05 × 42.10 
percent). The fully loaded hourly wage for a GS–15 Step 1 is $93.86 ($66.05 + $27.81). 
Costs 
Motor carriers, industry technological 
manufacturers, and drivers would not 
incur any new costs associated with this NPRM. Adopting and using windshield- mounted technologies is purely optional. Those who install and use windshield-mounted technologies would experience no added burdens or costs. 
In CMVs, drivers sit in an elevated 
position that greatly improves the forward visual field. When FMCSA previously granted exemptions, it found that doing so would likely achieve a level of safety equivalent to, or greater than, the level of safety achieved without the exemption. As described in Section VI. of this NPRM, since issuing the first temporary exemption from § 393.60(e)(1) in 2009, FMCSA is unaware of any crashes that have been attributed to the location of such devices. 
The expanded location—not more 
than 216 mm (8.5 inches) below the upper edge of the area swept by the windshield wipers, and not more than 175 mm (7 inches) above the lower edge of the area swept– is expected to keep pace with technological advances and further aid in meeting the statutory requirements of the FAST Act. The expanded area is outside the driver’s line of sight to the road, highway signs, and signals. 
Cost Savings 
We anticipate that this NPRM, if 
finalized consistent with the terms 
proposed, would generate cost savings to (1) motor carrier companies that file fewer periodic exemption requests, and (2) the Federal Government by reducing the volume of exemption requests to be reviewed and processed. 
Several manufacturers of windshield- 
mounted technologies have requested exemptions from FMCSA. We estimate that this takes about 2 hours of company time. Manufacturers, on average, apply for 3 exemptions per year. Table 3 provides the 10-year time horizon cost savings stream based on the yearly undiscounted $568 (rounded to the nearest whole dollar) cost savings to industry if this NPRM would be finalized in 2022.

Benefits 
The Agency was unable to identify 
literature that quantified the benefits of increasing the allowable windshield area for the mounting of vehicle safety technologies. In the absence of such analyses, the Agency did not quantify benefits associated with the NPRM, though it believes that the rule has the potential to improve the safety of CMV operations.
15 16The Agency also finds 
that CMVs outfitted with vehicle safety technologies under current exemptions do not present an increased safety risk compared to other CMVs. 
Discussion of Alternatives 
When preparing this NPRM, FMCSA 
considered two alternatives. In this 
section, we examine how the cost of the proposal would change with each alternative. 
Alternative 1: 
No Action. 
Using this alternative, FMCSA would 
accept the status quo and not change the current exemption approval 
requirements. This alternative currently limits the windshield area in which new safety technologies can be mounted to not more than 100 mm (4 inches) below the upper edge of the area swept by the windshield wipers or not more than 175 mm (7 inches) above the lower edge of the area swept by the windshield wipers. This alternative does not favor innovation and technological growth, nor does it reduce the overall burden to industry of applying for, and to the Federal Government of reviewing, exemptions. This alternative would maintain the approximately $10,705 (annualized, 7 percent discount rate) in annual costs associated with the overall 
exemption request and approval process. 
Alternative 2: 
Preferred Alternative— Revise 49 CFR 
393.60 to expand the windshield area 
where vehicle safety technologies could be installed on CMVs and revise 49 CFR 393.5 to broaden the definition of vehicle safety technology. 
Using this alternative, FMCSA would 
increase the allowable windshield area for installation of vehicle safety technologies. This would lead to an estimated $10,705 in annual cost savings without any estimated cost increase or reduction in benefits, as this analysis shows. 
B. Congressional Review Act 
Pursuant to the Congressional Review 
Act (5 U.S.C. 801–808), the Office of 
Information and Regulatory Affairs designated this rule as not a ‘‘major rule,’’ as defined by 5 U.S.C. 804(2).
17 
C. Advance Notice of Proposed Rulemaking 
Under 49 U.S.C. 31136(g), FMCSA is 
required to publish an advance notice of proposed rulemaking (ANPRM) or proceed with a negotiated rulemaking, if a proposed rule is likely to lead to the promulgation of a major rule. As this

the promulgation of a major rule, the Agency is not required to issue an ANPRM or to proceed with a negotiated rulemaking. 
D. Regulatory Flexibility Act 
The Regulatory Flexibility Act (5 
U.S.C. 601 et seq.), as amended by the 
Small Business Regulatory Enforcement 
Fairness Act of 1996,
18requires Federal 
agencies to consider the effects of the regulatory action on small business and other small entities and to minimize any significant economic impact. The term ‘‘small entities’’ comprises small businesses and not-for-profit organizations that are independently owned and operated and are not dominant in their fields, and governmental jurisdictions with populations of less than 50,000 (5 U.S.C. 601(6)). Accordingly, DOT policy requires an analysis of the impact of all regulations on small entities, and mandates that agencies strive to lessen any adverse effects on these businesses. 
The Agency expects that this NPRM, 
if finalized consistent with the proposed terms, would not have a significant economic impact on small entities. We expect a final rule consistent with the NPRM to result in cost savings to industry and the Federal Government. 
FMCSA expects the average costs to 
manufacturers of windshield-mounted equipment associated with avoiding the need for exemption applications would be reduced by $568 per year (annualized, 7 percent discount rate). We calculate that 100 percent of small equipment manufacturers impacted by this NPRM would have a cost savings less than 1 percent of their annual revenue. No small governmental jurisdictions would be impacted by this NPRM. 
Consequently, I certify that the 
proposed action would not have a significant economic impact on a substantial number of small entities. If you think that your business, organization, or governmental jurisdiction qualifies as a small entity and that this NPRM would have a significant economic impact on it, please submit a comment to the docket at the address listed in the 
ADDRESSES  
section of this preamble. In your comment, explain why you think it qualifies and how and to what degree this NPRM would economically affect it. 
E. Assistance for Small Entities 
In accordance with section 213(a) of 
the Small Business Regulatory Enforcement Fairness Act of 1996,
19 
FMCSA wants to assist small entities in 
understanding this NPRM so they can better evaluate its effects on themselves and participate in the rulemaking initiative. If the NPRM would affect your small business, organization, or governmental jurisdiction and you have questions concerning its provisions or options for compliance; please consult the person listed under 
FOR FURTHER  
INFORMATION CONTACT . 
Small businesses may send comments 
on the actions of Federal employees who enforce or otherwise determine compliance with Federal regulations to the Small Business Administration’s Small Business and Agriculture Regulatory Enforcement Ombudsman and the Regional Small Business Regulatory Fairness Boards. The Ombudsman evaluates these actions annually and rates each agency’s responsiveness to small business. If you wish to comment on actions by employees of FMCSA, call 1–888–REG– FAIR (1–888–734–3247). DOT has a policy regarding the rights of small entities to regulatory enforcement fairness and an explicit policy against 
retaliation for exercising these rights.

of 1995 (2 U.S.C. 1531–1538) requires Federal agencies to assess the effects of their discretionary regulatory actions. The Act addresses actions that may result in the expenditure by a State, local, or Tribal government, in the aggregate, or by the private sector of $170 million (which is the value equivalent of $100 million in 1995, adjusted for inflation to 2020 levels) or more in any 1 year. Because this NPRM would not result in such an expenditure, a written statement is not required. However, FMCSA does discuss the costs and benefits of this NPRM in the preamble. 
G. Paperwork Reduction Act 
This NPRM contains no new 
information collection requirements 
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501–3520). FMCSA notes that the burden associated with preparing an exemption request is not included in a currently approved information collection request (ICR), and is pursuing completion of that ICR outside of this rulemaking. H. E.O. 13132 (Federalism) 
A rule has implications for federalism 
under section 1(a) of E.O. 13132 if it has 
‘‘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.’’ FMCSA has determined that this rule would not have substantial direct costs on or for States, nor would it limit the policymaking discretion of States. Nothing in this document preempts any State law or regulation. Therefore, this rule does not have sufficient federalism implications to warrant the preparation of a Federalism Impact Statement. 
I. Privacy 
The Consolidated Appropriations Act, 
2005,
20requires the Agency to assess 
the privacy impact of a regulation that 
will affect the privacy of individuals. This NPRM would not require the collection of personally identifiable information (PII). Because this NPRM does not require the collection of PII, the Agency is not required to conduct a privacy impact assessment (PIA). Section 208 of the E-Government Act of 2002 (44 U.S.C. 3501 note) requires Federal agencies to conduct a PIA for new or substantially changed technology that collects, maintains, or disseminates information in an identifiable form. No new or substantially changed technology would collect, maintain, or disseminate information as a result of this rule. Accordingly, FMCSA has not conducted a PIA. 
The Agency will complete a Privacy 
Threshold Assessment (PTA) to evaluate the risks and effects the NPRM might have on collecting, storing, and sharing personally identifiable information. The DOT Privacy Office has determined that this rulemaking does not create privacy risk. 
J. E.O. 13175 (Indian Tribal 
Governments) 
This rule does not have Tribal 
implications under E.O. 13175, Consultation and Coordination with Indian Tribal Governments, because it does not have a substantial direct effect on one or more Indian Tribes, on the relationship between the Federal Government and Indian Tribes, or on the distribution of power and responsibilities between the Federal Government and Indian Tribes.

K. National Environmental Policy Act of 
1969 
FMCSA analyzed this NPRM for the 
purpose of the National Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321 et seq.) and determined this action 
is categorically excluded from further analysis and documentation in an environmental assessment or environmental impact statement under FMCSA Order 5610.1 (69 FR 9680), Appendix 2, paragraph 6.bb. The Categorical Exclusion (CE) in paragraph 6.bb. addresses regulations concerning vehicle operation safety standards (e.g., regulations requiring: Certain motor carriers to use approved equipment which is required to be installed such as an ignition cut-off switch, or carried onboard, such as a fire extinguisher, and/or stricter blood alcohol concentration standards for drivers, etc.), equipment approval, and/or equipment carriage requirements (e.g., fire extinguishers and flares). 
The proposed requirements in this 
rule are covered by this CE and the NPRM does not have any effect on the quality of the environment.
