In this scientific poster it is stated that serious offenses indicate deliberate risk-taking. These offenses (for instance alcohol/controlled substance offences) were used to investigate demographic, psychosocial and substance use correlates among high-school seniors. Students' self-administered questionnaires (n=1660; evaluating school-based substance-abuse prevention) were matched with first two-year driver histories. The sample averaged 18.2 years old, including 773 women (46.6%) and 887 men (53.4%). Of the women, 5.6% were non-white; the figure for men was 7.9%. Among young men, 13.1% had serious offenses. Among young women, 4.1% had serious offenses. Significant correlates of high-risk of high-risk driving by gender were determined by logistic regression analyses. Correlates were additive. Drivers with no risk factors had low rates of serious offenses, while those with all significant risk factors had high rates. For men, substance availability, grades, and smokeless tobacco use were significant. For women, alcohol use, alcohol misuse, and race were significant. Based on presence/absence of risk factors, probability rates of serious offenses ranged from 1% to 59%, with young women varying more than young men.
