Time Series Evaluation of the General Deterrent Effects of California's 1982 DUI Legislative Reforms. Volume 2 of Development of a DUI Accident and Recidivism Tracking System

摘要

The project evaluated the effects of legislative reforms to California's DUI countermeasure system. Time series analysis was used to evaluate the deterrent effects of these laws on the general population of DUI offenders as measured by effects in alcohol-related traffic accident rates, both statewide and in counties sharing similar demographic and enforcement patterns. A second set of analyses were performed to assess the significance of the formation of the emerging anti-drunk driving sentiment largely popularized by the formation of Mothers Against Drunk Driving (MADD). Both implementation of the DUI statutes, and the publicity and societal dynamics surrounding the creation of MADD, were found to be associated with reductions in subsequent alcohol-related fatal or injury accident rates, with evidence of more pronounced effects among injury accidents.
