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.

Importation of Commercial Motor Vehicles

This document proposes to add a definition of the term "import" to our regulation on the importation of motor vehicles.

208 49 CFR Part 595 Retro Fit On-Off Switches for Air Bags

To facilitate further the modification of vehicles to accommodate individuals with disabilities, the agency is proposing to expand the existing exemption from a statutory provision that prohibits specified types of commercial entities from either removing safety equipment or features installed on motor vehicles

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.

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, 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 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.
