Effects of introducing an administrative .05% blood alcohol concentration limit on alcohol-related collisions in Canada

Étienne Blais, François Bellavance, Alexandra Marcil, Laurent Carnis

Abstract

This articles presents the results of an evaluation of administrative laws introduced over time in different Canadian provinces to lower the permitted blood alcohol concentration (BAC) for driving or having care of a motor vehicle to .05% or less. Regression models for longitudinal data were used to estimate the effects of these laws on fatal alcohol-related collisions. Results reveal that significant decreases in the percentage of fatally injured drivers with prohibited BAC levels were recorded following the introduction of the laws. Reductions were observed for drivers at all drinking levels.
