EVALUATION OF THE BONNEVILLE COUNTY, IDAHO, DUI ACCIDENT PREVENTION PROGRAM

The results of an impact evaluation of the first 15 months of an accident prevention program in Bonneville County, Idaho, are presented. Project Safety is a comprehensive driving under the influence (DUI) program implemented in Bonneville County in October 1979. It provided an integrated systems approach to the drinking-driver problem by the enhancement of treatment, sentencing and parole, and rehabilitation process. DUI enforcement teams were added to the Bonneville County Sheriff's Office and the Idaho Falls Police Department. A public information component was also developed. Specific personnel were assigned system liaison responsibilities. A before-and-after analysis, which included two comparison locations, used an alcohol proxy measure (nighttime fatal and injury accidents occurring between 8:00 p.m. and 5:00 a.m.) to identify reductions in alcohol-related accidents. There was a reduction of 4.6 alcohol proxy accidents/month (a total of 64) during the study period. Reductions did not occur in comparison counties in the alcohol measure, although the direction of daytime accident trends was similar for all counties studied. State alcohol proxy accidents remained stable during the program period. An estimated $1 million in fatal and injury accident costs was avoided during the program period compared with actual total project costs of $312,471. The $1 million accident cost estimate excludes probable reductions in property-damage-only accidents. (Author)
