EVALUATION OF THE MICHIGAN TRIAL SUBSTITUTE MOTOR VEHICLE INSPECTION PROGRAM. FIRST YEAR INTERIM
In a two-year study, a checklane vehicle inspection program is being evaluated as a substitute for a periodic motor vehicle inspection program. The first year's effort, reported here, measured the percent of defective vehicles in two sampled counties and provided a baseline against which to measure the second-year results. The overall failure rate was 47.6%, but this was found to increase markedly with the age of the vehicle. Detailed tables of results for several vehicle systems are presented. As part of the study, a moving stopping test for braking capability was compared with a mechanic's inspection of the brakes.
