This study examines whether increasing alcohol taxes through beer, wine, and liquor taxes reduces underage drunk driving fatalities. The study uses data on alcohol taxes, alcohol consumption rates, miles driven adjusted for population, and percentages of total fatalities from drunk driving that involve those under 21 for each US state. Through multivariate regression analysis, the study finds some evidence that higher beer and wine taxes are associated with slightly lower percentages of underage drunk driving fatalities, but the results are not statistically significant. Adding liquor tax data to the model does not meaningfully change the results. Overall, the study finds limited evidence that higher alcohol taxes may help reduce underage drunk driving deaths.
