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.

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. |
Final Rule: Occupant Protection in Interior Impact; Side Impact Protection; Fuel System Integrity; Electric-Powered Vehicles: Electrolyte Spillage and Electrical Shock Protection; Side Impact Phase-In Reporting Requirements |

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. |

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. |

49 CFR Parts 571 | Child Restraint System - Anton's Law - FY 2005 This document responds to Section 4(b) and Section 3(b)(2) of Anton’s Law, which directed NHTSA to initiate rulemaking on child restraint system safety, with a specific focus on booster seats and restraints for children who weigh more than 50 pounds (lb). After the enactment of Anton’s Law, this agency increased the applicability of Federal Motor Vehicle Safety Standard (FMVSS) No. 213, Child restraint systems, from restraints recommended for children up to 50 lb to restraints recommended for children up to 65 lb. Today’s document proposes a further expansion, to restraints recommended for children up to 80 lb. It also proposes to require booster seats and other restraints to meet performance criteria when tested with a crash test dummy representative of a 10-year-old child. Section 4(a) and all other provisions of Section 3 were addressed in rulemaking documents issued previously by NHTSA. |

49 CFR Parts 523, 533 and 537 | Light Truck Average Fuel Economy Standards, Model Years 2008-2011 This final rule reforms the structure of the corporate average fuel economy (CAFE) program for light trucks and establishes higher CAFE standards for model year (MY) 2008-2011 light trucks. Reforming the CAFE program will enable it to achieve larger fuel savings, while enhancing safety and preventing adverse economic consequences. |

49 CFR Parts 523, 531, 534, 536, 537 | Average Fuel Economy Standards, Passenger Cars and Light Trucks, Model Years 2011-2015 Proposes substantial increases in the Corporate Average Fuel Economy (CAFE) standards for passenger cars and light trucks that would enhance energy security by improving fuel economy. Since the carbon dioxide (CO2) emitted from the tailpipes of new motor vehicles is the natural by-product of the combustion of fuel, the increased standards would also address climate change by reducing tailpipe emissions of CO2. Those emissions represent 97 percent of the total greenhouse gas emissions from motor vehicles. Implementation of the new standards would dramatically add to the billions of barrels of fuel already saved since the beginning of the CAFE program in 1975. |

49 CFR Parts 523, 531, 533, 534, 536 and 537 | Average Fuel Economy Standards, Passenger Cars and Light Trucks, Model Year 2011 NHTSA estimates that the MY 2011 standards will raise the industry-wide combined average to 27.3 mpg, save 887 million gallons of fuel over the lifetime of the MY 2011 cars and light trucks, and reduce CO2 emissions by 8.3 million metric tons during that period. |
