The latest notice says the measure was withdrawn, lifted or repealed, in whole or in part.
Parts and Accessories Necessary for Safe Operation; Certification and Labeling Requirements for Rear Impact Protection Guards
The Federal Motor Carrier Safety Administration (FMCSA) amends the Federal Motor Carrier Safety Regulations (FMCSR) to rescind the requirement that the rear impact guard be permanently marked or labeled with a certification from the impact guard manufacturer as required by the applicable Federal Motor Vehicle Safety Standard (FMVSS) promulgated by the National Highway Traffic Safety Administration (NHTSA). The certification label or marking provides motor carriers purchasing new trailers or new impact guards to replace damaged devices with a means to determine whether the equipment is certified as meeting the FMVSS. However, the labeling or marking requirement has proven problematic for motor carriers when the label or marking becomes illegible or wears off during the service life of the trailer or guard. This final rule eliminates an unintended regulatory burden on motor carriers without compromising safety, as it does not affect the applicable FMVSS. The final rule also rescinds a guidance document pertaining to illegible, incomplete, or missing rear impact guard certification labels. Effective 23 March 2026. Petitions for reconsideration of this final rule must be submitted to the FMCSA Administrator no later than 23 March 2026. 91 Federal Register (FR) 7874, 19 February 2026; Title 49 Code of Federal Regulations (CFR) Part 393: This final rule and the notice of proposed rulemaking notified as G/TBT/N/USA/1684/Rev.1 are identified by Docket Number FMCSA-2025-0107.

Notice of proposed rulemaking - The Federal Motor Carrier Safety Administration (FMCSA) proposes to amend the Federal Motor Carrier Safety Regulations (FMCSRs) to rescind the requirement that the rear impact guard be permanently marked or labeled with a certification from the impact guard manufacturer as required by the National Highway Traffic Safety Administration's (NHTSA) applicable Federal Motor Vehicle Safety Standard (FMVSS). The certification label or marking provides motor carriers purchasing new trailers or new impact guards to replace damaged devices with a means to determine whether the equipment is certified as meeting the FMVSS. However, the labeling or marking requirement has proven problematic for motor carriers when the label or marking becomes illegible or wears off during the service life of the trailer or guard. This proposal would eliminate an unintended regulatory burden on motor carriers without compromising safety, as this NPRM would not affect the applicable FMVSS. The proposal would also rescind a guidance document pertaining to illegible, incomplete, or missing rear impact guard certification labels.
