THE IMPACT OF MINIMUM DRINKING AGE LAWS ON FATAL CRASH INVOLVEMENTS: AN UPDATE OF THE NHTSA ANALYSIS

This study updates a 1985 NHTSA analysis of the impact Minimum Drinking Age Laws (MDA) have on traffic fatalities (HS-806 902, Nov. 1985). The 1985 study estimated that MDAs are 13% effective in reducing traffic fatalities involving drivers that were no longer legally permitted to consume alcohol. This updated analysis confirms the 13% estimate. Using more crash data, the analysis indicates that MDAs are 12% effective in reducing traffic fatalities involving affected drivers. The 12% estimate is consistent with the 13% estimate in that it is within the statistical range surrounding the 13% estimate. This research note describes the method used to calculate the estimate of MDA effectiveness and presents the estimated number of lives saved by MDAs for each year (1975-1987) as well as the cumulative number of lives saved. The conclusion is that MDAs saved between 977 to 1071 lives in 1987 and 7433 to 8142 lives cumulatively between 1975-1987.
