In an amplification of previous work, a number of controlled studies of highway crashes and citations (with parallel roadlock samples) are treated in a consistent manner by a Bayesian technique, and relative probabilities of involvement derived as functions of blood alcohol concentrations (BAC) and of other important predictor variables. Relative "Effectiveness" estimates for hypothetical BAC limits are 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 supplemented 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 relatiohships and of enforcement implications. Some tentative implications for control practices are drawn, with recommendations for research.
