HIGHWAY SPEED REGULATION AND ALCOHOL RELATED ACCIDENTS

The focus of this research is the effect which recent speed limit increases have had upon accidents that are alcohol related. Although there has been considerable work on the highway safety effects of speed legislation and on alcohol related accidents, there has been surprisingly little work that explicitly examines the relationship between these. A behavioral model of drinking and driving is proposed which suggests that the higher speed limit will reduce alcohol related accidents in higher relative to lower speed environments. Data on alcohol related accidents as well as several theoretically important determinants of such accidents were collected for each county in Indiana over the period 1981 through 1989. Random effects regression models for alcohol related accidents, in total and disaggregated along various dimensions, were estimated. For the state as a whole, the law had no effect on highway safety. However, consistent with the implications of the behavioral model, the law did significantly reduce alcohol related accidents in higher relative to lower speed environments. This was true for virtually every accident sub-group examined. (A)
