This article summarizes current specific evidence about the impact of public policy measures on alcohol-related motor vehicle crashes. The public policy measures considered are (1) minimum drinking age laws, (2) taxation of alcoholic beverages, (3) drinking and driving laws, (4) laws and regulations governing the physical availability of alcoholic beverages, and (5) server intervention programs. It is concluded that certain public policy measures reduce alcohol-related crashes. These measures included higher taxes on alcoholic beverages and at least some laws and regulations governing the physical availability of alcohol (as well as minimum drinking age). The article suggests that strengthening drinking and driving laws without also adopting these other measures may have less than optimum (and possibly disappointing) effects.
