The study was conducted to determine the in-use condition of automobiles on the U.S. highways. One primary objective was to assess the condition of vehicles in PMVI (Periodic Motor Vehicle Inspection) states as compared with vehicles in a Random MVI state. Pennsylvania, New Jersey, and Washington, D.C. were used as the PMVI areas, and California was used as the Random MVI state. Considerable effort was expended to minimize the variance that existed in the data collected from the various diagnostic centers used in the study. Specific criteria were developed for the selection of the centers used in the study. Also, standard component test criteria were developed for evaluating tested components as being in a 'pass' or 'defective' condition. One significant conclusion of the report is that there is a significant difference in the condition of vehicles in Pennsylvania, New Jersey, and Washington, D.C., all of which have PMVI, and the condition of vehicles in California, which has Random MVI, with the vehicles in the PMVI states being in significantly better condition than those in the Random MVI state. A survey of current literature that is directly applicable to the objectives of the study is included in the final report. (Author)
