The study was conducted to determine the safety status of automobiles in-use on the U.S. highways. The data collected indicated that age is a very critical factor with respect to the number of 'out of specification conditions' found on vehicles. Also, the results indicate that vehicles in States with rigorous PMVI systems are in significantly better condition than vehicles in States with random MVI or no MVI. The component test criteria was modified to make it more objective by assigning levels of defectiveness where appropriate. The existing vehicle-in-use computer software was redesigned to make it more general and provide it with certain added capabilities such as the inclusion of all vehicle specifications necessary for the automobiles on the U.S. highways. A diagnostic equipment correlation study was made on the various name brands of brake testers and front-end geometry equipment that are normally found in the diagnostic centers utilized for studies of this type.
