EVALUATION OF THE MICHIGAN TRIAL SUBSTITUTE VEHICLE INSPECTION PROGRAM
The two-year study evaluated the Michigan checklane inspection system as a trial substitute for a periodic motor vehicle inspection program. Two counties served as the test areas. One county had a simulated PMVI, while the other had a checklane inspection of 15% of the cars. Random checklanes were used in 1975 and 1976 to estimate the condition of the cars in each county, with minimum sample sizes of 2000 cars for each study group. A special study in 1975 compared a moving stopping test to a wheel-pull brake inspection. The conclusion was that the MST was more stringent and easier to perform. In 1976 the repair rates for vehicles in the PMVI group were also determined for several safety components and were reported.
