The National Highway Traffic Safety Administration (NHTSA) is proposing to amend its air brake standard to improve the stopping distance performance of commercial trucks. Based on current safety trend data and brake system technologies, NHTSA is proposing to reduce the required stopping distance for truck tractors by 20 to 30 percent. The proposed rule would cover all truck tractors equipped with air brakes. The proposed rule does not include single unit trucks, buses, or trailers.
