Summary
This 1983 report evaluates the crash reduction potential and instructional effectiveness of the Safe Performance Curriculum (SPC), a competency-based secondary school driver education program. The study was motivated by the need for rigorous, scientific assessment of driver education programs, following earlier efforts by the National Highway Traffic Safety Administration (NHTSA) and the Highway Research Board to define proper evaluation standards. The primary objective was to determine whether a high-quality, task-based curriculum could significantly reduce accidents and violations among teenage drivers compared to minimal training or no formal education. The research employed a randomized controlled trial design involving approximately 18,000 volunteer high school students in the DeKalb County School System in Georgia. Students were randomly assigned to one of three groups: (1) the Safe Performance Curriculum (SPC), a comprehensive 70-hour course including classroom, simulation, range, and on-street training; (2) the Pre-Driver Licensing (PDL) group, which received only the minimum training required to obtain a license; and (3) a Control group, which received no formal driver education. Battelle Columbus Laboratories conducted the evaluation, monitoring students for two to four years post-assignment. The primary metrics for ultimate performance were the number and types of crashes and traffic violations recorded in students’ driving histories. The study also analyzed intermediate measures, such as knowledge and performance tests, and administrative factors like cost and implementation challenges. The findings revealed no statistically significant differences in overall accident or violation means among the SPC, PDL, and Control groups when examining the entire driving records of all assigned students. However, analyses controlling for the time period of licensed driving showed that students in the SPC and PDL groups had significantly lower accident and violation rates during the first six months after obtaining their licenses compared to the Control group. This short-term benefit diminished over time, with differences becoming statistically insignificant in subsequent periods. Crucially, this initial advantage was neutralized by the fact that students in the driver education groups obtained their licenses approximately 23 to 32 days earlier than those in the Control group. Consequently, the earlier exposure to driving offset the short-term safety gains, resulting in no net difference in overall crash or violation rates across the three groups. The study concludes that while comprehensive driver education programs like the SPC can produce short-term improvements in driving safety immediately following licensure, these effects do not persist over the long term. The earlier licensing of trained students effectively cancels out the initial safety benefits, leading to equivalent overall crash and violation rates compared to untrained drivers. The report implies that driver education alone may not be sufficient for sustained crash reduction, highlighting the complex interplay between training quality, licensing timing, and long-term driving behavior.
Key finding
The Safe Performance Curriculum and Pre-Driver Licensing programs produced significantly lower accident and violation rates than the Control group only during the first six months of licensed driving, but this short-term benefit was offset by earlier licensing, resulting in no significant overall difference in crash or violation rates among the groups.
