For almost 40 years, public policies about DUI have relied greatly on the results of the Grand Rapids Study (Borkenstein, 1974), which showed an increased risk of accident as the BAC increase, and on many studies replicating this study revealing age and gender differences. Since 1997, new licensed drivers in Quebec are subject to a two year probationary period while they have a maximum of four demerits points and 0,00% BAC legal limit. Also we are facing a situation where the proportion of killed drivers with BAC over 0,08% shifted from 40% ten years ago to a minimum of 22,5% in 1999. The goal of this study is to analyze the alcohol-related risk of fatally injured drivers in a context of general decreasing contribution of alcohol to accident and the special case of graduated licensing system.
