Impact Analysis of the Raised Legal Drinking Age in Illinois

D M Maxwell, National Highway Traffic Safety Administration

Abstract

This report contains an analysis of the impact of the raised legal drinking age in Illinois in 1980. Illinois raised its legal drinking age in January 1980 from 19 to 21. Monthly single vehicle night male driver involvements (in traffic accidents) from 1977-1980 were analyzed, as the impact measure. Box-Tiao Intervention Analysis was used tb develop impact assessment models relating the change in driver involvements to the implementation of the raised legal drinking age. An 8.8 percent reduction in single vehicle night male driver involvements was found for drivers in the affected age groups. /Abstract from summary report page/
