National Penalties for Drunk Drivers Linked to Reduced Risk of Harms to Others

The risks of riding with an impaired driver or being involved in a crash caused by another person’s drinking are lower in countries that have comprehensive penalties for driving under the influence, according to an international study in Alcoholism: Clinical & Experimental Research. Previous research on the effects of drunk-driving policies has focused on aggregate outcomes such as accident rates or fatalities involving alcohol-impaired drivers. Relatively slight attention has been paid to harms caused by another driver’s impairment, although these “secondhand” effects are widespread and serious; in the US in 2015, almost 40 percent of drunk-driving deaths were of victims other than the impaired driver. Investigators explored whether national policies relating to drink-driving, and regional drinking cultures, were associated with such effects.

Statewide Retail Alcohol Compliance Checks Cut Drink-Driving Crashes Among Drivers Under-21 Years Old

Regular statewide retail checks for compliance with the legal drinking age are associated with a sustained reduction in alcohol-related crashes for drivers aged under 21, according to an analysis of 11 years’ data from South Carolina. Previous research has shown that reductions in underage drinking lead to a decrease in drink-driving and alcohol-related crashes. However, few studies have assessed the impact of purposeful alcohol compliance checks – in which authorities use an underage informant to attempt to buy alcohol – on drink-related road accidents. The new study, reported in Alcoholism: Clinical and Experimental Research, evaluated the impact of the South Carolina Alcohol Enforcement Team (AET) program for reducing retail alcohol access to underage youth on drinking and driving crashes among drivers under 21 years old.
