Abstract

In an amplification of previous work, a number of control studies of highway crashes in citations (with parallel roadblock samples) are treated in a consistent manner by a Bayesian technique, and relative probabilities of involvement or derived as functions of blood alcohol concentrations (BAC) and other important predictor variables. Relative effectiveness estimates for hypothetical BAC limits or derived from the assumption of "perfect enforcement" i.e. universal acquiescence to a given BAC limit. Estimated effectiveness is compared on the basis of differences in driver population characteristics and in the chosen criterion. These results are supplanted by comparisons with uncontrolled studies of alcohol in fatal crashes. The role of self-reported drinking habits is considered as a moderator of hazard-BAC relationships and of enforcement implications. Some tentative in locations for control practices are drawn, with recommendations for research.
