Summary
This report presents an initial evaluation of North Carolina’s Alcohol and Drug Education Traffic Schools (ADETS), a statewide program mandated by Senate Bill 691 (1979) for first-time Driving Under the Influence (DUI) convictees. The primary motivation was to provide an educational intervention to modify drinking-driving behavior, reduce recidivism, and increase knowledge of DUI laws. The program offered participants an incentive: successful completion allowed for the reinstatement of full driving privileges after six months, rather than the standard twelve-month suspension. The study, conducted by the UNC Highway Safety Research Center, assessed the program’s administration, educational effectiveness, stakeholder perceptions, and impact on driving behavior. The evaluation employed a mixed-methods design. Researchers analyzed pre- and post-course knowledge tests from 1,594 students across urban and rural areas to measure knowledge gain. They surveyed ten target groups, including judges, attorneys, law enforcement, and students, to gauge perceptions of the program’s fairness and effectiveness. Additionally, the study compared the driving records of 33,825 ADETS attendees against a comparison group of 16,429 first-time offenders who did not attend school. This quasi-experimental analysis controlled for variables such as age, race, and blood alcohol concentration at the time of the initial arrest, though it could not account for socioeconomic status or courtroom dynamics. The findings revealed significant educational gains but poor behavioral outcomes. Test scores increased from a mean of 56.0% to 76.5%, with the largest improvements in areas concerning DUI law and drugs. Stakeholders generally viewed the program favorably and as primarily educational, though they noted a need for separate programs for multiple offenders. Crucially, the analysis of driving records showed that ADETS attendees had significantly higher rates of DUI recidivism and crashes than the non-attending comparison group. The authors attribute this negative outcome to the reduction in license suspension time for attendees; because license suspension is a potent deterrent, shortening it likely offset any benefits gained from the educational course. The report concludes that while the ADETS curriculum effectively increases knowledge, the program’s structure as a substitute for license suspension undermines its deterrent effect. The authors recommend that future legislation require ADETS attendance in addition to, rather than in place of, other sanctions. They also suggest improving financial reporting to better manage class sizes, which were found to correlate with knowledge gain, and revising the knowledge test to adhere to standard construction procedures. The study highlights the complexity of balancing rehabilitative education with punitive sanctions in DUI prevention.
Key finding
ADETS attendees had significantly higher DUI recidivism and crash rates than non-attendees, a result attributed to the shorter license suspension periods granted to program participants.
