Intervening to decrease the probability of alcohol-impaired driving: Impact of novel field sobriety tests

This study aimed to evaluate the ability of novel field sobriety tests to predict breath alcohol content (BAC) and perceptions of driving risk. Passersby (N=210) at two downtown locations near local bars and one on-campus location near a late-night dining facility were participants. Hours of participation were between 10:00 p.m. and 2:00 a.m. Participants rated their perceived risk to drive at their current intoxication level before completing three sobriety tests, consisting of a hand-pat, tracing test, and Romberg test, followed by the self-rating of their perceived risk to drive. A Lifeloc FC20 breath alcohol test (±.005 g/dL) was administered to participants after completing the final set of questions. The performance feedback did not enhance awareness of one's risk to drive at a given BAC, in spite of the fact that each of the sobriety tests performed better than chance at predicting participant intoxication. In actuality, Greek-life females' perception of themselves was that they were less at-risk to drive after the sobriety tests.
