This proposal is in response to a petition for rulemaking from the Truck Trailer Manufacturers Association (TTMA). The proposed change would provide relief from a regulatory requirement without impacting safety. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> Comments must be received on or before July 29, 2025. </EFFDATE> <HD SOURCE="HED">ADDRESSES:</HD> You may submit comments identified by Docket Number FMCSA-2025-0120 using any of the following methods: • <E T="03">Federal eRulemaking Portal:</E> Go to <E T="03">https://www.regulations.gov/docket/FMCSA-2025-0120/document.</E> Follow the online instructions for submitting comments. • <E T="03">Mail:</E> Dockets Operations, U.S. Department of Transportation, 1200 New Jersey Avenue SE, West Building, Ground Floor, Washington, DC 20590-0001. • <E T="03">Hand Delivery or Courier:</E> Dockets Operations, U.S. Department of Transportation, 1200 New Jersey Avenue SE, West Building, Ground Floor, Washington, DC 20590-0001, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

The Motor Carrier Safety Act of 1984 required the Secretary to “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 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 [which is the basis for much of the FMCSRs], or ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 28k characters.
