AIR BRAKED VEHICLE PERFORMANCE: FMVSS NO. 121 BRAKING SYSTEMS VERSUS PRE-FMVSS NO. 121 BRAKING SYSTEMS AND STABILITY AUGMENTATION DEVICES
Road tests were conducted on 3 truck tractors and 4 semitrailers to evaluate the effects of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, Air Brake Systems--Trucks, Buses and Trailers, on braking system performance. Tests were run in accordance with procedures specified in the standard and also in accordance with other test procedures that were developed during the course of the program to simulate typical on-highway emergency situations. The use of three different stability augmentation devices on tractor-trailer combinations was also evaluated to determine if these devices affected vehicle braking performance. The report presents a description of the test program and an analysis of the results.
