The efficacy of novel field sobriety tests to predict breath alcohol content (BAC) and perceptions of driving risk was evaluated. Participants (N = 210) were passersby at two downtown locations near local bars and one on-campus location near a late-night dining facility between the hours of 10:00 p.m. and 2:00 a.m. Participants gave ratings of their perceived risk to drive at their current level of intoxication, then completed three sobriety tests (a hand-pat, tracing test, and Romberg test), and finally provided new ratings of their perceived risk to drive. After completing the final set of questions, participants were administered a Lifeloc FC20 breath alcohol test (±.005 g/dL). Each of the sobriety tests performed better than chance at predicting participant intoxication, but the performance feedback did not enhance awareness of one's risk to drive at a given BAC. Actually, after the sobriety tests, Greek-life females perceived themselves to be less at-risk to drive.
对新型现场清醒度测试预测呼气酒精含量（BAC）及驾驶风险认知的效果进行了评估。参与者（N = 210）为晚上10点至凌晨2点间当地酒吧附近两个市中心地点及一个深夜餐饮设施附近校内地点的路人。参与者对其在当前醉酒程度下驾驶的感知风险进行评分，然后完成三项清醒度测试（拍手法、追踪测试和罗姆伯格测试），最后对其驾驶的感知风险给出新的评分。完成最后一组问题后，对参与者进行了Lifeloc FC20呼气酒精测试（±0.005 g/dL）。每项清醒度测试在预测参与者醉酒程度方面都比随机猜测表现得更好，但表现反馈并未增强对在给定BAC水平下驾驶风险的认知。实际上，在清醒度测试后，联谊会女性认为自己驾驶风险更低。
