NHTSA issues Federal Motor Vehicle Safety Standards (FMVSS) to implement laws from Congress. These regulations allow us to fulfill our mission to prevent and reduce vehicle crashes.

49 CFR Part 575 | Stars on Cars: New Car Assessment Program (NCAP) Safety Labeling A provision of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) requires new passenger vehicles to be labeled with safety rating information published by the National Highway Traffic Safety Administration under its New Car Assessment Program. NHTSA is required to issue regulations to ensure that the labeling requirements “are implemented by September 1, 2007.” This final rule is issued to fulfill that mandate. |

49 CFR Part 575 | Tire Fuel Efficiency Consumer Information Program Proposes a broad new consumer information program for replacement tires to inform consumers about the effect of tires on fuel efficiency, safety, and durability. This consumer information program would implement a national tire fuel efficiency rating system for replacement tires, with the information provided to consumers at the point of sale and online. Fuel efficiency ratings are expected to inform consumers so that they will be better informed about replacement tire performance. This consumer information program seeks to enhance energy security and reduce costs by improving fuel economy. Information would also be provided about safety and durability. |

218 | 49 CFR Part 571. | Motorcycle Helmets A notice of proposed rulemaking (NPRM) amending FMVSS No. 218 was published on May 21, 2015 (80 FR 29458). The NPRM set forth an interpretation of the definition of “motor vehicle equipment” in the United States Code, as amended by the Moving Ahead for Progress in the 21st Century (MAP–21) Act, and requested comments on two proposed changes to the motorcycle helmet safety standard, FMVSS No. 218. NHTSA proposed to add a definition of “motorcycle helmet” and modify the existing performance requirements of the standard by adding a set of dimensional and compression requirements. These requirements and the associated test procedures would identify those helmets whose physical characteristics indicate that they likely cannot meet the existing performance requirements of the standard. Third, NTHSA proposed an optional alternative compliance process for manufacturers whose helmets do not comply with the proposed dimensional and compression requirements, but do comply with the performance requirements and all other aspects of FMVSS No. 218 . If this proposal is adopted, NHTSA will publish a list of helmets that have complied with the alternative compliance process and can therefore be certified by their manufacturers. The NPRM was the result of the agency’s assessment of other actions that could be taken to further increase the percentage of motorcyclists who wear helmets that comply with the helmet standard. |

208 | 49 CFR Part 571 | Seat Belts on Motorcoaches In accordance with NHTSA’s 2007 Motorcoach Safety Plan and DOT’s 2009 Departmental Motorcoach Safety Action Plan, NHTSA is issuing this NPRM to propose to amend the Federal motor vehicle safety standard (FMVSS) on occupant crash protection (FMVSS No. 208) to require lap/shoulder seat belts for each passenger seating position in new motorcoaches.This NPRM also proposes to require a lap/shoulder belt for the motorcoach and large school bus driver’s seating positions, which currently are required to have either a lap or a lap/shoulder belt. |

Air Brake Systems Amends the FMVSS on air brake systems to improve the stopping distance performance of truck tractors. The rule requires the vast majority of new heavy truck tractors to achieve a 30 percent reduction in stopping distance compared to currently required levels. For these heavy truck tractors (approximately 99 percent of the fleet), the amended standard requires those vehicles to stop in not more than 250 feet when loaded to their gross vehicle weight rating (GVWR) and tested at a speed of 60 miles per hour (mph). For a small number of very heavy severe service tractors, the stopping distance requirement will be 310 feet under these same conditions. In addition, this final rule requires that all heavy truck tractors must stop within 235 feet when loaded to their “lightly loaded vehicle weight” (LLVW). |
