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.

NHTSA: 49 CFR Parts 531, 533, and 537; EPA: 40 CFR Parts 86 and 600 | Establish Light-Duty Vehicle Greenhouse Gas Emission Standards and CAFE Standards EPA and NHTSA are issuing this joint proposal to establish a National Program consisting of new standards for light-duty vehicles that will reduce greenhouse gas emissions and improve fuel economy. EPA is proposing greenhouse gas emissions standards under the Clean Air Act, and NHTSA is proposing Corporate Average Fuel Economy standards under the Energy Policy and Conservation Act, as amended. These standards apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, covering model years 2012 through 2016, and represent a harmonized and consistent National Program. Under the National Program, automobile manufacturers would be able to build a single light-duty national fleet that satisfies all requirements under both programs while ensuring that consumers still have a full range of vehicle choices. |

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. |

Occupant Crash Protection This document adopts NHTSA’s proposal to require all designated seating positions in rear seats, other than side-facing seats, be equipped with Type 2 integral lap/shoulder safety belts. Side-facing seats may be equipped with either a Type 1 lap belt or a Type 2 belt. This final rule responds to a Congressional mandate that the agency begin to phase-in requirements for lap/shoulder belts for all rear seating positions, wherever practicable, not later than September 1, 2005. |

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. |

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. |
