II. Legal Basis for the Rulemaking

    This SANPRM is based on 49 U.S.C. 31502 (originally enacted as part 
of the Motor Carrier Act of 1935 (1935 Act)); 49 U.S.C. chapter 311, 
subchapter III (originally enacted as part of the Motor Carrier Safety 
Act of 1984 (1984 Act)); and 49 U.S.C. chapter 313 (originally enacted 
as part of the Commercial Motor Vehicle Safety Act of 1986 (1986 Act)). 
Both 49 U.S.C. 31502 and 49 U.S.C. chapter 311, subchapter III vest 
broad rulemaking authority in the Secretary of Transportation 
(Secretary) to prescribe regulations on CMV safety, which includes the 
authority to issue regulations governing ADS-equipped CMV operations 
and operators. In this regard, section 31502(b) provides, ``The 
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.'' Section 31136(a) requires the Secretary of Transportation 
to ``prescribe regulations on commercial motor vehicle safety. The 
regulations shall prescribe minimum safety standards for commercial 
motor vehicles.'' The provision further requires that: ``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 the 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 . . .'' (49 U.S.C. 31136(a)(1)-(5)). Additionally, section 
31308 gives the Secretary broad authority to ``prescribe regulations on 
minimum uniform standards for the issuance of commercial drivers' 
licenses [CDLs] and learner's permits by the States . . . .'' This 
SANPRM is based primarily on section 31502(b), which authorizes 
requirements to address the safety of operations and equipment of a 
motor carrier, and on section 31136(a)(1), which requires provisions to 
ensure that CMVs are maintained, equipped, and operated safely. 
Sections 31136(a)(2) through (5) are not immediately relevant to this 
SANPRM. These statutes provide sufficient legal authority for the 
Secretary to issue regulations on the operation of ADS-equipped CMVs. 
Before prescribing regulations, the Secretary must consider their costs 
and benefits (49 U.S.C. 31136(c)(2)(A) and 31502(d)).
    The Administrator of FMCSA is delegated authority under 49 CFR 1.87 
to carry out the functions vested in the Secretary by 49 U.S.C. 
chapters 311, 313, and 315 as they relate to CMV operators, programs, 
and safety.

III. Executive Order (E.O.) 12866 (Regulatory Planning and Review) and 
E.O. 13563 (Improving Regulation and Regulatory Review)

    This SANPRM is a not a significant regulatory action under section 
3(f) of E.O. 12866, as supplemented by E.O. 13563. Accordingly, the 
Office of Management and Budget has not reviewed it under these orders.
    Executive Orders 12866 and 13563 require agencies to provide a 
meaningful opportunity for public participation. Accordingly, the 
Agency has asked commenters to answer a variety of questions to elicit 
practical information about alternative approaches, including the 
associated costs and benefits of those approaches, and relevant 
scientific, technical, and economic data.

IV. Background

A. FMCSA's 2019 ANPRM

    FMCSA is responsible for overseeing the safety of CMVs, their 
drivers, and their operation in interstate commerce. The Agency works 
with Federal, State, and local enforcement agencies, the motor carrier 
industry, and interested stakeholders to reduce crashes, injuries, and 
fatalities involving large trucks and buses. The FMCSRs provide rules 
to support the safe operation of CMVs, and these rules apply to motor 
carriers who operate ADS-equipped CMVs. Since 2017, FMCSA has engaged 
in multiple stakeholder outreach activities and has taken other actions 
to assist the Agency in understanding issues related to ADS-equipped 
CMV operations and to consider what amendments to the FMCSRs may be 
necessary to reduce safety risk associated with the operation of ADS-
equipped CMVs. In 2019, FMCSA summarized previous outreach and other 
actions related to ADS-equipped CMVs in an ANPRM (84 FR 24449, 24450-
51, May 28, 2019). The ANPRM also requested public comment about which 
FMCSRs may need to be amended, revised, or eliminated to facilitate the 
safe introduction of ADS-equipped CMVs onto the Nation's roadways. In 
this regard, the ANPRM posed specific questions on the following 
topics: whether the FMCSRs require a human driver; CDL endorsements; 
drivers' hours of service rules; medical qualification standards for 
human operators; distracted driving and monitoring; requirements to 
ensure safe driving; inspection, repair, and maintenance; roadside 
inspections; cybersecurity; and confidentiality of shared information. 
FMCSA extended the comment period to August 28, 2019 (84 FR 37228, Jul. 
31, 2019), and the Agency received 122 comments from individuals and 59 
from organizations. Interested parties can view the comments the Agency 
received at https://www.regulations.gov/docket/FMCSA-2018-0037/comments.
    In the ANPRM, FMCSA explained that the Department adopted the SAE 
International's definitions for the levels of driving automation set 
forth in SAE J3016 (``Taxonomy and Definitions for Terms Related to 
Driving Automation Systems for On-Road Motor Vehicles''). The six 
levels of automation range from Level 0 (driver support features but no 
driving automation) to Level 5 (full driving automation). FMCSA 
continues to explore the potential risks and safety benefits of Levels 
0-3 driving automation and driver assistance technologies. FMCSA, 
however, does not believe there is a need to revise the FMCSRs to 
address the integration of Levels 0-3 equipment because a licensed 
human CMV driver must be seated behind the wheel of these vehicles at 
all times to perform, or be ready to take over, dynamic driving tasks. 
The focus of this notice is Level 4 and 5 ADS-equipped CMVs because it 
is only at those levels that an ADS can control all aspects of the 
dynamic driving task without any expectation of an intervention from a 
human driver.

B. Departmental and Modal Administration Publications and Actions

    Since FMCSA's publication of the ANPRM, the Department has 
continued engagement with key transportation stakeholders to develop a 
national policy framework to facilitate the safe integration of ADS 
technology, as well as other emerging technologies, into the 
transportation system. Prioritizing safety while supporting the power 
of innovation to transform transportation for the better are central to 
the Department's approach, as memorialized in both the National Roadway 
Safety Strategy (NRSS) and the U.S. DOT Innovation Principles, both 
released in January 2022.\1\ The NRSS outlines the Department's 
comprehensive approach to significantly reducing serious injuries and 
deaths with a long-term goal of zero roadway fatalities. The NRSS 
recognizes the Department's responsibility to use holistic approaches 
to assess the safety of emerging technologies such as ADS. The NRSS 
explains that the Department is actively researching test methods, 
procedures, and criteria to assess long-term safety benefits of ADS, as 
well as broader impacts on workers, drivers, and all people who use the 
Nation's roadways.
---------------------------------------------------------------------------

    \1\ The NRSS is available at https://www.transportation.gov/sites/dot.gov/files/2022-02/USDOT-National-Roadway-Safety-Strategy.pdf.
---------------------------------------------------------------------------

    Additionally, the NRSS describes actions taken by the Department 
and DOT modal administrations to enable the safe deployment of new and 
emerging vehicle technologies. For example, the National Highway 
Traffic Safety Administration (NHTSA) issued Standing General Order 
2021-01 on June 29, 2021, amended on August 5, 2021, that requires 
identified vehicle manufacturers and operators to report to NHTSA 
crashes involving vehicles equipped with ADS or certain advanced driver 
assistance systems.\2\ The Standing General Order, which remains in 
effect until June 2024, enables NHTSA and the Department to obtain 
timely and transparent notification of real-world crashes associated 
with vehicles equipped with an ADS and, when appropriate, may lead DOT 
modal administrations to gather additional data and information or 
conduct an investigation, when warranted, into emerging safety issues 
potentially arising from the on-road testing, development, use, or 
deployment of new driving automation technologies.
---------------------------------------------------------------------------

    \2\ The Standing General Order, as well as crash report data, is 
available at https://www.nhtsa.gov/laws-regulations/standing-
general-order-crash-
reporting#:~:text=NHTSA%20issued%20the%20General%20Order,are%20free%2
0of%20defects%20that.
---------------------------------------------------------------------------

    The U.S. DOT Innovation Principles will guide the Department's work 
in supporting transportation innovation.\3\ Innovations consistent with 
these principles should reduce deaths and serious injuries on the 
roadways. The Department will also encourage partnerships and 
collaborations through an outcomes-based approach. FMCSA's approach to 
safety oversight of motor carriers operating ADS-equipped CMVs is 
consistent with the Department's innovation principles and commits 
FMCSA to fostering purpose-driven innovation that is technology 
neutral, and protects the interests of the public, workers, and 
communities.

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

V. Discussion and Supplemental Questions for Response

    ADS-equipped CMVs have the potential to produce measurable safety 
benefits in crashes involving human error. ADS-equipped CMVs, however, 
present operational characteristics and challenges that may introduce 
new and complex safety risks that need to be monitored and may require 
FMCSA to

[[Page 6694]]

modify existing and/or adopt new regulatory standards. ADS developers 
are actively engaged in the development, testing, and limited 
deployment of ADS-equipped CMVs, and promoting their use in commercial 
motor carrier operations. Although many ADS-equipped CMVs are being 
tested in manufacturer or developer owned fleets, many developers and 
manufacturers are also working to integrate their ADS equipment into 
existing motor carrier fleets. To mitigate potential safety risks 
associated with in-service use of ADS-equipped CMVs, FMCSA is 
developing an appropriate regulatory framework.
    In this SANPRM, which is a supplement to the ANPRM published May 
28, 2019, FMCSA invites comment on additional questions and those 
issued in the previous ANPRM, to help FMCSA assess benefits, costs, and 
other impacts of any potential proposal issued later. If interested 
parties have new information regarding the questions presented in the 
2019 ANPRM, those comments may be submitted in response to this SANPRM. 
The 2019 ANPRM is available at 84 FR 24449 or at the following link: 
https://www.regulations.gov/document/FMCSA-2018-0037-0131.

A. Notification by Motor Carriers Operating Level 4 or 5 ADS-Equipped 
CMVs

    To more effectively oversee Level 4 or 5 ADS-equipped CMV 
operations, FMCSA is considering establishing a requirement for motor 
carriers to notify FMCSA that they will operate those CMVs in 
interstate commerce without a human driver behind the wheel. It may be 
necessary to require motor carriers operating such vehicles to notify 
the Agency to facilitate monitoring of those operations and give FMCSA 
the opportunity to address any unique in-service safety issues involved 
in the operations of such vehicles, and, if necessary, to target safety 
interventions to correct those issues. FMCSA therefore seeks comment on 
(1) regulatory approaches that would enable the Agency to obtain 
relevant safety information and (2) the current and anticipated size of 
the population of motor carriers operating ADS-equipped CMVs.
Questions
    1.1. Should FMCSA require motor carriers operating Level 4 or 5 
ADS-equipped CMVs to notify FMCSA before operating those vehicles in 
interstate commerce without a human driver behind the wheel? If so, 
what potential methods or procedures should be established to notify 
FMCSA of those operations?
    1.2. Before operating in interstate commerce, should motor carriers 
be required to submit information, data, documentation, or other 
evidence that demonstrates to FMCSA that motor carriers seeking to 
operate Level 4 or 5 ADS-equipped CMVs have appropriate safety 
management controls in place to operate the vehicle in accordance with 
the manufacturer's specifications and with Federal requirements? If so, 
please describe any recommended approaches including the information to 
be provided and appropriate techniques for reviewing that information. 
If available, provide cost estimates for proposed approaches.
    1.3. What data should FMCSA collect and maintain regarding Level 4 
or 5 ADS-equipped CMVs engaged in interstate transportation? How would 
such information be used and how would it improve FMCSA's ability to 
oversee the safe operation of Level 4 or 5 ADS-equipped CMVs?
    1.4. What is the current size of the Level 4 or 5 ADS-equipped CMV 
population? What is the anticipated size of the population within 5 
years? What might the size of the population be in 10 years?
    1.5. On average, how many days are Level 4 or 5 ADS-equipped CMVs 
expected to be operational per year?

B. Oversight for Remote Assistants

    As FMCSA explained in the ANPRM, at Level 5 driving automation, the 
ADS technology will be expected, by definition, to be capable of 
performing all driving functions under all conditions. For Level 4 
driving automation the ADS technology would be limited to certain 
operational design domains (ODD). However, when a Level 4 CMV reaches 
the limit of its ODD, continued operation may require a human driver, 
either seated behind the wheel or located remotely, to directly control 
the CMV. (See the ANPRM for more information on operational design 
domains (84 FR 24449, 24452)). Human drivers who may operate an ADS-
equipped CMV from a remote location are generally referred to as remote 
drivers.\4\ FMCSA stated in the ANPRM that the FMCSRs applicable to 
drivers seated behind the wheel of the CMV, such as drug and alcohol 
use and testing, CDL requirements, hours of service, distracted 
driving, and medical qualification standards, should continue to apply 
to remote drivers who are able to take control of an ADS-equipped CMV 
operating on a public road. This remains FMCSA's position.
---------------------------------------------------------------------------

    \4\ The definition of remote driver is a driver who is not 
seated in a position to manually exercise in-vehicle braking, 
accelerating, steering, and transmission gear selection input 
devices (if any), but is able to operate the vehicle.
---------------------------------------------------------------------------

    During FMCSA's continued engagement with stakeholders, the Agency 
has learned that some motor carriers' operational models may also 
include the use of a person operating as a remote assistant \5\ who 
would remotely monitor the Level 4 or 5 ADS-equipped CMV. On an as-
needed basis, the remote assistant would engage (via a wireless 
telematics connection) with the vehicle if/when the ADS is unable to 
perform the dynamic driving task and enters a minimal risk condition 
due to a system fault, mechanical failure, an event that caused the 
vehicle to enter into a condition or location outside its ODD, and/or 
other anomalies that the ADS was unable to negotiate. In such 
circumstances the remote assistant may enable the ADS to complete the 
driving task but in all circumstances the on-board ADS would complete 
or execute the actual vehicle control maneuvers. That is, the remote 
assistant would not engage in direct control of the vehicle throttle, 
steering, accelerator, turn signals, lighting, or other vehicle control 
functions. The remote assistant may also engage with law enforcement 
personnel, first responders and/or other public officials engaged in 
traffic and CMV oversight operations. FMCSA seeks information on what 
requirements, if any, should be imposed on persons performing remote 
assistant duties for motor carriers operating Level 4 or 5 ADS-equipped 
CMVs.
---------------------------------------------------------------------------

    \5\ The definition of remote assistance is a human who provides 
remote information or advice to an ADS-equipped vehicle in 
driverless operation in order to facilitate trip continuation when 
the ADS encounters a situation it cannot manage.
---------------------------------------------------------------------------

Questions
    2.1. To what extent should the Federal requirements otherwise 
applicable to CMV drivers (such as hours-of service limitations, drug 
and alcohol testing, and physical qualifications), also apply to a 
remote assistant who is not expected to take control of the dynamic 
driving task of an ADS-equipped CMV operating at Level 4?
    2.2. What, if any, aspects of the remote assistant job function may 
require FMCSA oversight including minimum standards and/or auditing, 
e.g., training, physical qualifications, and other job-performance 
related measures? Please provide rationale and evidence for the 
recommended manner of oversight.
    2.3. Are there any qualification requirements that FMCSA should

[[Page 6695]]

consider for remote assistants, such as related experience, e.g., as a 
CDL holder?
    2.4. Are there any specific limitations that should be imposed on 
the working conditions of remote assistants, such as limitations on the 
number of ADS-equipped CMVs that a remote assistant is simultaneously 
responsible for or the number of hours that a remote assistant may 
work?
    2.5. Are there any other considerations that FMCSA should be aware 
of relating to individuals who may function as remote assistants?

C. Vehicle Inspection and Maintenance

    As indicated in the ANPRM, motor carriers operating Level 4 or 5 
ADS-equipped CMVs must comply with existing vehicle inspection and 
maintenance regulations, including the requirements for pre-trip, post-
trip, periodic, and roadside inspections, unless and until those 
regulations are revised through an FMCSA final rule. Additionally, the 
ANPRM noted that motor carriers operating Level 4 or 5 ADS-equipped 
CMVs would necessarily require a means to ensure that the ADS equipment 
is properly maintained and functioning.
    Level 4 or 5 ADS-equipped CMVs have the potential to operate almost 
continuously, except for re-fueling and maintenance. FMCSA is therefore 
considering whether additional inspection requirements would be 
appropriate for Level 4 or 5 ADS-equipped CMVs to reduce overall safety 
risk associated with this new technology and to account for their 
extended periods of operation without direct human observation.
    At the same time, roadside inspections of Level 4 or 5 ADS-equipped 
CMVs would be uniquely challenging in the absence of a human driver to 
engage in the inspection process. For example, during a Level 1 \6\ 
roadside inspection, a human driver is generally required to 
communicate with enforcement officers and perform tasks associated with 
the inspection, such as testing the braking system, lighting functions, 
and the fifth wheel movement. The Agency therefore is soliciting 
comment to better inform its rulemaking proposals in the areas of 
inspection and maintenance of ADS-equipped CMVs.
---------------------------------------------------------------------------

    \6\ See https://www.cvsa.org/inspections/all-inspection-levels/ 
for a description of inspection levels.
---------------------------------------------------------------------------

    The Commercial Vehicle Safety Alliance (CVSA) recently released a 
new program and procedures on inspections of ADS-equipped CMVs, which 
it developed through a multiparty working group.\7\ FMCSA requests 
public comment on the CVSA document,\8\ and it welcomes information and 
comment on activities of other stakeholder groups, including consensus 
standards bodies, that are considering ADS technology and deployment.
---------------------------------------------------------------------------

    \7\ See https://www.cvsa.org/news/new-enhanced-cmv-inspection-program/.
    \8\ CVSA's ``Enhanced CMV Inspection Program for Automated 
Vehicle Motor Carrier Operations'' can be found in the docket for 
this SANPRM.
---------------------------------------------------------------------------

Questions
    3.1. Should Level 4 or 5 ADS-equipped CMVs be subject to pre-trip 
inspection requirements for their mechanical and ADS components in 
addition to those specified in 49 CFR 392.7, including those which 
might necessitate new inspection equipment, before such CMVs are 
dispatched and after a specified period of operation? If so, what 
methods should be used to conduct these additional inspection items, 
what equipment components should be inspected, what documentation 
should be required, who should be responsible for conducting those 
inspections and what qualifications or specialized training should be 
required, and how frequently should the additional inspections be 
conducted?
    3.2. If additional inspections, inspection equipment, or additional 
qualifications for inspectors are proposed, provide an estimate of the 
costs associated with such additional requirements including the 
approximate time to complete the additional inspection requirements, 
costs of any proposed training if additional inspector requirements are 
proposed, and the paperwork burden associated with such training.
    3.3. What technical barriers exist to conducting conventional 
roadside inspections (which require interactions with the human driver) 
of Level 4 or 5 ADS-equipped CMVs and what approaches currently exist 
or might be developed to remove those barriers?
    3.4. What, if any, pre-trip inspection requirements, documentation, 
and communications capability (for making the results of such 
inspections available to law enforcement personnel), should be imposed 
on motor carriers operating Level 4 and 5 ADS-equipped CMVs as a 
condition for by-passing conventional roadside inspection stations?
    3.5. If Level 4 or 5 ADS-equipped CMVs are not required by the 
States to undergo roadside inspections during operation, what 
information should be communicated by the motor carrier and CMV to the 
State inspectors (e.g., the results of potential alternative pre-trip 
inspections, and/or the real-time operational status and condition of 
safety critical systems such as brakes, tires, lighting systems, 
steering, and ADS components)? Are there other data and performance 
information that would need to be made available to ensure adequate 
vehicle maintenance and safe operations?
    3.6. What communication systems currently exist that would allow 
roadside inspection officers to receive information regarding Level 4 
or 5 ADS-equipped CMVs, and what information could be transmitted via 
these systems regarding the mechanical condition of the CMV and other 
operational documentation, (e.g., shipping documents and origin/
destination), while in route?
    3.7 Under what safety situations should State inspectors and/or 
FMCSA receive immediate notification of an unsafe maintenance or 
operational issue, if any? What data and information would need to be 
provided in instances such as tow-away crashes or those that disable 
key operational features of a CMV? Under such safety situations, what 
return to service process would ensure any maintenance and operation 
issues have been addressed?
    3.8. If Level 4 or 5 ADS-equipped CMVs are not subject to State 
roadside inspections, how would law enforcement agencies and motor 
carriers ensure that such CMVs are not used to engage in unlawful 
activity, e.g., human trafficking, cargo theft?
