NHTSA Proposes Electronic Stability Control on Heavy Trucks

May 18th, 2012 | By | Category: Spotlight

The National Highway Traffic Safety Administration (NHTSA) has proposed to establish a new Federal Motor Vehicle Safety Standard requiring Electronic Stability Control (ESC) systems on truck tractors and certain buses with a gross vehicle weight rating greater than 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.

The proposal would go into effect for most truck tractors and covered buses produced two years after publication of a final rule. For three-axle tractors with one drive axle, tractors with four or more axles, and severe service tractors, there would be two years additional lead-time.

NHTSA will hold a public hearing in the summer of 2012 and announce the date for the hearing in a supplemental Federal Register notice.
