— The Truck Renting and Leasing Association (TRALA) is reviewing a proposal by the National Highway Traffic Safety Administration (NHTSA) to establish federal regulations mandating rear object detection systems on new straight trucks. NHTSA's notice of proposed rulemaking issued Sept. 12 proposes requiring rear object detection systems on all new straight trucks with a GVWR between 10,000 and 26,000 lbs. The notice proposes that either a mirror system or a rear video system could be used to comply with the new requirement. The NHTSA notice also suggests that the agency is still considering an expansion of the proposed requirements to apply to vehicles in other weight classes. Additionally, NHTSA is contemplating a regulation that would call for the retrofitting of straight trucks already on the road in order to comply with the rear object detection system standard being proposed for new trucks.
