INTERVENTION STRATEGIES FOR ACCIDENT-INVOLVED DRIVERS: AN EXPERIMENTAL EVALUATION OF CURRENT CALIFORNIA POLICY AND ALTERNATIVES

This project was designed to evaluate current and alternative strategies for selecting and treating accident-involved drivers in California. The standard criteria for selecting accident-involved drivers for treatment (involvement in a fatal accident or three accidents within one year) were contrasted with an expanded selection strategy which included convictions as well as accidents as criteria for selection. The standard reexamination treatment was compared to two alternative treatments--an accident-avoidance session and a mailed pamphlet/self-administered test. Comparisons between the standard and expanded selection criteria showed that drivers selected by the standard criteria were significantly affected by treatment, while most drivers selected by the expanded criteria were not. Comparisons between treatments showed the accident-avoidance session to be the most effective treatment for standard criteria drivers. Based on the results of the statistical tests and benefit-cost analyses, it was recommended that: (1) the accident-avoidance session replace the reexamination as the DMV's operational intervention for standard criteria drivers, and (2) the pamphlet/self-test treatment be implemented for expanded criteria drivers with minimal conviction histories. It was estimated that implementation of these two recommendations would prevent an estimated 545 accidents annually, producing $3,680,000 in societal benefits at a cost of $147,000, resulting in total annual net benefits of $3,533,000.
