Abstract
The purpose of this study was to determine the effects of police enforcement and the use of signs and posters in promoting seat belt use by nighttime tavern patrons. Ten taverns in two cities served as sites. Because previous research has shown that tavern patrons are overrepresented in the impaired driving population, and that seat belt use decreases the likelihood of serious injury or death, results of this study suggest that enforcement of seat belt use could reduce casualties resulting from impaired driving.
