National Highway Traffic Safety Administration October 30, 2017 – Federal Register Recent Federal Regulation Documents

This final rule addresses a petition for reconsideration of the final rule for FMVSS No. 136, Electronic stability control systems for heavy vehicles. The petitioner, Truck and Engine Manufacturers Association (EMA), requested that NHTSA amend the test conditions for the agency's performance test by allowing a larger lane width for long wheelbase truck tractors. After a careful technical review of the petition and the issues raised by the petitioner, the agency has decided to grant the petition because there is sufficient evidence to indicate that a larger lane width is needed for testing of long wheelbase truck tractors.
