Ninety-three students were asked to estimate their blood alcohol level (BAL) and to report whether they were legally impaired as they left a fraternity party. They were also asked to report the number of 10-oz cups of beer they had consumed during the party. Actual BALs were tested on a breathalyzer and the subjects' self-reported number of cups were compared with the cup-by-cup consumption data collected during the party. The results showed that many subjects were to report correctly whether they were legally impaired. However, those subjects with higher BALs tended to overestimate their actual BAL while underestimating the number of cups of beer they had consumed. These results are discussed in terms of the ability of individuals to make judgments about their level of impairment. The implications of these results for the prevention of drunken driving are also addressed.
