NEGLIGENT OPERATOR TREATMENT EVALUATIONSYSTEM. PROGRAM EFFECTIVENESS REPORT NUMBER 5 (DETAILED FINDINGS)

Thw negligent-operator treatment evaluation system provides annual cost-effectiveness analyses of the California Department of Motor Vehicles' negligent-operator (neg-op) program. The evaluation system is based on a comparison of the driving records of neg-ops (drivers with multiple traffic conviction and/or accident points) who arae randomly assigned to a intervention or a no-contact control group. Three levels of progressively more severe neg-op interventions were evaluated in this manner, the fourth-level intervention (the most severe) was evaluated indirectly using data from level-3 recidivists. Drivers at each level were eligible to receive a standard intervention or an alcohol-tailored interventi. The data for each of the first three levels revealed a statistically significant reduction in accidents. At level 3 there was a significant difference in the effects of the standard and alcohol interventions, with the standard intervention showing a significant reduction in accidents and the alcohol intervention group displaying a higher accident rate than its control. Regarding injury accidents, when the results of levels 1 and 2 were combined, the alcohol lettters were significantly more effective that the corresponding standard interventions; at level 3 the interventions showed the opposite effects, with the standard probation hearing intervention being significantly more effective than the alcohol intervention. In each of the first 3 levels the standard intervention was significantly more effective in reducing citations than the corresponding alcohol interventions.
