Background: Driving under the influence of alcohol, alone or in combination with other substances, is a leading cause of injury and premature death among young adults, and college-educated individuals are at particularly high risk.

Method: This study describes prospective 7-year trends in drunk and drugged driving among a young-adult sample beginning with the second year of college, and documents the extent of continuity in such behaviors over time. Originally recruited as incoming first-year students at one large public university, participants (N=1,253) were interviewed annually about driving while drunk and driving while under the influence of other drugs. Follow-up rates were high (>75% annually).

Results: Among individuals with access to a car, annual prevalence peaked at modal age 21 for both drunk driving (24%) and drugged driving (19%). During college, drunk driving increased significantly whereas drugged driving was stable. Post-college declines were statistically significant for both drugged and drunk driving (p<.05), but less pronounced for the latter. Likelihood of drunk driving among individuals who engaged in heavy episodic drinking did not change significantly over time, but likelihood of drugged driving among marijuana-using individuals declined significantly after college (p<.05). Most of the college drunk drivers (72%) and college drugged drivers (64%) continued the behavior after college. A minority of drunk drivers (30%) and drugged drivers (28%) reported doing so in only one year.

Conclusion: Results suggest that, rather than being a transient aberration, drugged and drunk driving tend to be part of an ongoing pattern of behavior that persists after college.

Learning Objectives:
Describe trends in drunk and drugged driving during and after college. Articulate the importance of developmental changes in substance-related driving risk behaviors among college-educated young adults, in the context of post-college changes in drinking and drug use. Discuss intervention opportunities for reducing drunk/drugged driving risk among college students and college-educated young adults.
