While there is little research specifically dealing with college students and drunk driving, there is ample evidence of frequent, heavy drinking by students. A series of projects was undertaken to explore college students' drinking behavior and attitudes related to alcohol-impaired driving. These projects included: (1) analysis of behavioral observations of 243 students drinking in bars; (2) analysis of behavioral observations of 65 students drinking at a fraternity party; (3) a review of bottled beer consumption by university students; (4) three questionnaire studies of drinking/driving attitudes and behaviors; (5) interviews with six community officials regarding their views of drunk driving and its prevention; and (6) interviews with 26 beer drinkers at the student union. Results indicated that risk taking among drunk drivers was related to the number of passengers and their degree of alcohol impairment. Students' reported movtivation for drinking was personal rather than social. Results also showed that men drink more beer than women in bars, and that both men and women drink more beer when it is served in pitchers. Students were good estimators of their degree of impairment; however, students with blood alcohol content greater than ten percent overwhelmingly underestimated the amount of beer they had drunk.
