The National Highway Traffic Safety Administration has completed its 200-tractor antilock field test and has begun a 50-trailer test program which includes 50 trailers in 5 fleets. The tests include sophisticated on-board flight recorders which monitor each antilock system 50 times a second and record wheel speeds, brake pressures, and solenoid activations. Reports from drivers and mechanics are also used. Powering of the trailer antilock, and the way in which it differs from powering tractor antilocks are pointed out. Four different systems for powering trailer antilock systems are considered: standard 7-pin connector; European-style ISO connector in addition to the 7-pin; 'halo' connector (7-pin modified to include an additional 8 circuits); and battery power. The costs of trailer antilock are listed and discussed.
