49 CFR Part 533

Light Truck Average Fuel Economy Standards, Model Years 2005-2007

This final rule established the average fuel economy standards for light trucks that will be manufactured in the 2005-2007 model years (MYs). Chapter 329 of Title 49 of the United States Code requires the issuance of these standards. The standards for all light trucks manufactured by a manufacturer is set at 21.0 mpg for MY 2005, 21.6 mpg for MY 2006, and 22.2 mpg for MY 2007. This rule is effective May 5, 2003.

49 CFR Part 538

Under 49 CFR Part 538, Automotive Fuel Economy Manufacturing Incentives for Alternative Fuel Vehicles

To provide an incentive for the production of vehicles that can operate on certain alternative fuels as well as on regular petroleum fuels, Congress established a special procedure for calculating the fuel economy of those vehicles for determining compliance with the Corporate Average Fuel Economy standards.

49 CFR Part 538

Automobile Fuel Economy Manufacturing Incentives for Alternative Fueled Vehicles

This final rule extends the incentive created by the Alternative Motor Fuels Act of 1988 (AMFA) to encourage the continued production of motor vehicles capable of operating on alternative fuels for four additional model years covering model years (MY) 2005 to MY 2008. Under the special procedures for calculating the fuel economy of those vehicles contained in AMFA, alternative and dual fueled vehicles are assigned a higher fuel economy value for CAFE purposes, which can result in manufacturers earning credits for their fleets. The final rule limits the maximum amount of credit that may be applied to any manufacturers' fleet to 0.9 mpg per fleet during MY 2005 - MY 2008.

49 CFR Part 563 Event Data Recorders -- Final Rule; response to petitions for reconsideration

NOTE: In Table III of this document, the accuracy specification for the "Frontal air bag deployment, time to deploy/first stage, driver" should read +/- 2 ms. We have determined that the missing number is a typographical error that is not present in the originally signed notice. A correction notice to fix this error will soon be published in the Federal Register.

136 49 CFR Part 571 Electronic Stability Control Systems for Heavy Vehicles

This proposes to establish a new Federal Motor Vehicle Safety Standard No. 136 to require electronic stability control (ESC) systems on truck tractors and certain buses with a gross vehicle weight rating of greater than 11,793 kilograms (26,000 pounds). ESC systems in truck tractors and large buses are designed to reduce untripped rollovers and mitigate severe understeer or oversteer conditions that lead to loss of control by using automatic computer-controlled braking and reducing engine torque output. In 2012, we expect that about 26 percent of new truck tractors and 80 percent of new buses affected by this proposed rule will be equipped with ESC systems. We believe that ESC systems could prevent 40 to 56 percent of untripped rollover crashes and 14 percent of loss-of-control crashes. By requiring that ESC systems be installed on truck tractors and large buses, this proposal would prevent 1,807 to 2,329 crashes, 649 to 858 injuries, and 49 to 60 fatalities at less than $3 million per equivalent life saved, while generating positive net benefits.

49 CFR Part 571

Federal Motor Vehicle Safety Standards; Rearview Mirrors

In response to a petition for rulemaking, this document proposes to require straight trucks with a gross vehicle weight rating (GVWR) of between 4,536 kilograms (10,000 pounds) and 11,793 kilograms (26,000 pounds) to be equipped with a rear object detection system.
