This report evaluates the impact of the Commercial Driver License (CDL) program on fatal and fatal/injury accidents involving heavy vehicles operated by drivers licensed in California. The program, which was initiated in January 1985, began a new commercial-license classification and endorsement system, implemented stronger licensing standards and more comprehensive tests of knowledge and driving competency, required drivers to report specific violations to employers, and provided for more stringent post-licensing sanctions to negligent operators. Intervention time series analysis was used for data analysis. The results indicate that the CDL program did not have a statistically significant effect on the fatal or fatal/injury accident series.
