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.","document_number":"2026-03255","html_url":"https://www.federalregister.gov/documents/2026/02/19/2026-03255/parts-and-accessories-necessary-for-safe-operation-certification-and-labeling-requirements-for-rear","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-02-19/pdf/2026-03255.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-03255.pdf?1771422314","publication_date":"2026-02-19","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Motor Carrier Safety Administration","name":"Federal Motor Carrier Safety Administration","id":181,"url":"https://www.federalregister.gov/agencies/federal-motor-carrier-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/181","parent_id":492,"slug":"federal-motor-carrier-safety-administration"}],"excerpts":"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..."},{"title":"Federal Motor Vehicle Safety Standards; Federal Motor Carrier Safety Regulations; Parts and Accessories Necessary for Safe Operation; Speed Limiting Devices; Withdrawal","type":"Proposed Rule","abstract":"FMCSA and NHTSA withdraw the September 7, 2016 joint NPRM that proposed to require that heavy vehicles (those with a gross vehicle weight rating (GVWR) of more than 11,793 kilograms (26,000 pounds)) be equipped with a speed limiting device that is maintained at a set speed. FMCSA also withdraws its May 4, 2022 ANSPRM, which announced FMCSA's intent to proceed with a speed limiter rulemaking. The ANSPRM stated that FMCSA was preparing a supplemental notice of proposed rulemaking (SNPRM) to propose that motor carriers operating commercial motor vehicles (CMVs) in interstate commerce with a gross vehicle weight or GVWR of at least 11,794 kilograms (26,001 pounds), whichever is greater, and that are equipped with an engine control unit (ECU) capable of governing the maximum speed, be required to limit the CMV to a speed to be determined by the rulemaking and to maintain that ECU setting for the service life of the vehicle.

The retrofitting requirements were adopted by the Federal Highway Administration (FHWA) on March 31, 1999, and require that motor carriers engaged in interstate commerce install retroreflective tape or reflex reflectors on the sides and rear of semitrailers and trailers that were manufactured prior to December 1, 1993, have an overall width of 2,032 mm (80 inches) or more, and a gross vehicle weight rating of 4,536 kg (10,001 pounds) or more. With the passage of more than 30 years since the NHTSA requirements were implemented, FMCSA believes the vast majority of trailers currently in use on the Nation's highways were manufactured after 1993 so the retrofitting rule is no longer necessary. This proposal would eliminate obsolete regulatory text without compromising safety.","document_number":"2025-09705","html_url":"https://www.federalregister.gov/documents/2025/05/30/2025-09705/parts-and-accessories-necessary-for-safe-operation-retroreflective-sheeting-on-semitrailers-and","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-05-30/pdf/2025-09705.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-09705.pdf?1748376909","publication_date":"2025-05-30","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Motor Carrier Safety Administration","name":"Federal Motor Carrier Safety Administration","id":181,"url":"https://www.federalregister.gov/agencies/federal-motor-carrier-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/181","parent_id":492,"slug":"federal-motor-carrier-safety-administration"}],"excerpts":"FMCSA proposes to rescind the requirements for retroreflective sheeting on semitrailers and trailers manufactured prior to December 1, 1993, which is the compliance date for the National Highway Traffic Safety Administration's (NHTSA) conspicuity rules..."},{"title":"Parts and Accessories Necessary for Safe Operation; Certification and Labeling Requirements for Rear Impact Protection Guards","type":"Proposed Rule","abstract":"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.","document_number":"2025-09704","html_url":"https://www.federalregister.gov/documents/2025/05/30/2025-09704/parts-and-accessories-necessary-for-safe-operation-certification-and-labeling-requirements-for-rear","pdf_url":"https://www.govinfo.gov/content/pkg/FR-2025-05-30/pdf/2025-09704.pdf","public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2025-09704.pdf?1748376909","publication_date":"2025-05-30","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Motor Carrier Safety Administration","name":"Federal Motor Carrier Safety Administration","id":181,"url":"https://www.federalregister.gov/agencies/federal-motor-carrier-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/181","parent_id":492,"slug":"federal-motor-carrier-safety-administration"}],"excerpts":"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..."}]}
