Moser, Barbara A.; Bressler, Lois D.; Williams, Richard B.

The purpose of this study was to determine if drug usage is related to driving history. Laboratory analyses of urine samples, in-depth interviews, and public driving records were obtained to investigate the relationship of traffic accidents and violations between male users and nonusers of alcohol and drugs. Data were being collected in six geographical areas. The frequency and amount of drugs used were analyzed in terms of driving performance for 1,889 arrestees for serious crimes. In general the results show that for this select population, drug using drivers have no worse driving records, in terms of accidents and convictions, than the nondrug user drivers.
