Regulations

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.

226 49 CFR Parts 571, 585 Ejection Mitigation

This final rule establishes a new Federal Motor Vehicle Safety Standard No. 226, "Ejection Mitigation" to reduce the partial and complete ejection of vehicle occupants through side windows in crashes, particularly rollover crashes. The standard applies to the side windows next to the first three rows of seats, and to a portion of the cargo area behind the first or second rows, in motor vehicles with a gross vehicle weight rating (GVWR) of 4,536 kilogram (kg) or less (10,000 pounds (lb) or less). To assess compliance, the agency is adopting a test in which an impactor is propelled from inside a test vehicle toward the windows. The ejection mitigation safety system is required to prevent the impactor from moving more than a specified distance beyond the plane of a window.

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.

216 49 CFR Parts 571 and 585 Roof Crush Resistance; Phase-In Reporting Requirements

As part of a comprehensive plan for reducing the risk of rollover crashes and the risk of death and serious injury in those crashes, this final rule upgrades the agency’s safety standard on roof crush resistance in several ways.

214 49 CFR Parts 571 and 585 Side Impact Protection

This final rule incorporates a dynamic pole test into Federal Motor Vehicle Safety Standard (FMVSS) No. 214, “Side impact protection.” To meet the test, vehicle manufacturers will need to assure head and improved chest protection in side crashes. It will lead to the installation of new technologies, such as side curtain air bags and torso side air bags, which are capable of improving head and thorax protection to occupants of vehicles that crash into poles and trees and vehicles that are laterally struck by a higher-riding vehicle.
