THE TRAFFIC SAFETY IMPACT OF TWO EXPERIMENTAL MOTORCYCLE LICENSING PROGRAMS

This report summarizes the final analyses and evaluation of the relative effectiveness of two improved motorcycle licensing programs compared to California's standard licensing program. The findings are based on a sample of 40,834 original applicants who were randomly assigned to the programs over a 3-year period (1976-78). The two improved programs were identical to each other with the exception that one (Program B) required that applicants failing the driving test complete a remedial skills training program. The driver record analyses indicated a statistically significant reduction in motorcycle accident rates during the year after application in each of the two improved licensing programs compared to the present program. The magnitude of the accident reductions ranged from 15% to 21%. Comparisons on the other criterion measures revealed that the two improved programs did not differ from the present program in their impact on motorcycle and automobile convictions, automobile accidents, and total accidents and convictions. Nevertheless, the improved program with remedial training did result in a significant reduction in total number of accidents involving an injury or fatality. Further statistical analyses of the training component confirmed that the remedial training increased the accident-reducing impact of the program. Both improved programs were cost-beneficial on all of the cost-benefit indices. A modified version of the improved licensing program (MOST II) has been implemented at numerous locations throughout California; the traffic safety impact of the modifications will be evaluated in a subsequent study.
