Abstract

As a follow-up to their previous study, the authors conducted this research to (1) determine if the enactment of six minimum legal drinking age (MLDA) 21 laws is associated with reductions in the rate of underage drinking drivers involved in fatal crashes after the enactment date, and (2) determine if the adoption of other key drinking and driving laws and socioeconomic conditions in the states have an effect on underage drinking driver fatal crashes. This paper outlines the study methods, presents the findings, and discusses the results of the study. They found that four of the six underage drinking laws were significantly associated with reductions in underage drinking and driving fatal crashes. Three of the general impaired driving and traffic safety laws examined were significantly associated with reductions in underage drinking-driving fatalities. However, the four underage drinking laws had a greater effect.
