abstract="The California Department of Motor Vehicles (DMV) implemented and evaluated a pilot driver improvement program involving the withholding (&quot;masking&quot;) from public inspection of one conviction from the driving record of qualifying drivers. To qualify for masking, the driver had to complete and return a mailed, self-administered test and remain free of traffic convictions and accidents for a period of 6 months after selection into the program. This Home Instruction/Point Reduction Incentive (HI/PRI) countermeasure was developed in two distinct versions: the Speed HI/PRI was designed for multiple violators of the 55 Maximum Speed Law (MSL), and the Negligent Operator (Neg-Op) HI/PRI was designed for drivers classified as negligent operators based on their traffic conviction record. Both HI/PRI countermeasures covered the safety and energy-saving advantages of 55-MSL compliance; the Neg-Op HI/PRI included general traffic safety material as well. The multiple 55-MSL violators were assigned at random to either the Speed HI/PRI or a no-contact comparison group. The negligent operators were assigned at random to one of four conditions: the Neg-Op HI/PRI, the existing DMV group educational meeting, a modified group meeting incorporating 55-MSL issues, or a no-contact comparison group. The Speed HI/ PRI and Neg-Op HI/PRI were each estimated to be cost-beneficial on the basis of accidents prevented. In addition, the Neg-Op HI/PRI had a larger estimated effect on accidents and lower cost than the group meeting countermeasures, which were also cost-beneficial. The coverage of 55-MSL issues in the group meeting did not appear to influence its effect in reducing either accidents or convictions. All of the countermeasures appeared to reduce subsequent convictions.<p />",
