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.
FMVSS Number | Part | Subject | Actions |
---|---|---|---|
126 | 49 CFR Parts 571 & 585 | Federal Motor Vehicle Safety Standards; Electronic Stability Control Systems As part of a comprehensive plan for reducing the serious risk of rollover crashes and the risk of death and serious injury in those crashes, this rule establishes Federal Motor Vehicle Safety Standard (FMVSS) No. 126 to require electronic stability control (ESC) systems on passenger cars, multipurpose passenger vehicles, trucks, and buses with a gross vehicle weight rating of 4,536 Kg (10,000 pounds) or less. ESC systems use automatic computer-controlled braking of individual wheels to assist the driver in maintaining control in critical driving situations. NHTSA estimates ESC will reduce single-vehicle crashes of passenger cars by 34% and single vehicle crashes of sport utility vehicles (SUVs) by 59%, with a much greater reduction of rollover crashes. NHTSA estimates ESC would save 5,300 to 9,600 lives and prevent 156,000 to 238,000 injuries in all types of crashes annually once all light vehicles on the road are equipped with ESC. |

111 | 49 CFR, Parts 571 & 585 | FMVSS, Rearview Mirrors The Cameron Gulbransen Kids Transportation Safety Act of 2007 directs NHTSA issue a final rule amending the agency’s Federal motor vehicle safety standard on rearview mirrors to improve the ability of a driver to detect pedestrians in the area immediately behind his or her vehicle and thereby minimize the likelihood of a vehicle’s striking a pedestrian while its driver is backing the vehicle. Pursuant to this mandate, NHTSA is proposing to expand the required field of view for all passenger cars, trucks, multipurpose passenger vehicles, buses, and low-speed vehicles rated at 10,000 pounds or less, gross vehicle weight. NHTSA is proposing to specify an area immediately behind each vehicle that the driver must be able to see when the vehicle’s transmission is in reverse. It appears that, in the near term, the only technology available with the ability to comply with this proposal would be a rear visibility system that includes a rear-mounted video camera and an in-vehicle visual display. Adoption of this proposal would significantly reduce fatalities and injuries caused by backover crashes involving children, persons with disabilities, the elderly, and other pedestrians. |
