ALCOHOL-RELATED ACCIDENTS AND DUIL BREATH TESTS IN MICHIGAN: 1981

Michigan accident and drunk-driving arrest data for 1981 were analyzed. Data include all accidents investigated by police agencies and subsequently processed by the Michigan Department of State Police. Drunk-driving arrest data, also for 1981, were obtained from Breathalyzer Test Logs (BTLs). These logs contain entries for all breath tests given in conjunction with DUIL arrests. Data for DUIL arrestees who did not take a breath test are not included. DUIL data have been analyzed with respect to age, sex, state of residence, and BAC (blood alcohol concentration). Information about drivers with two or more arrests during 1981 is also included. The country, hour of day, and month of the arrest are also discussed. The BTLs contain data that identify whether the arrest arose from a driving violation or from an accident, and this factor is discussed as well. Regression analyses relating alcohol-related accidents and DUIL arrests were undertaken for Michigan's 83 counties. Traffic volume information was used as a control variable in these studies. A DUIL enforcement index for each county, and for the state as a whole, was determined.
