NEGLIGENT-OPERATOR TREATMENT EVALUATION SYSTEM. PROGRAM EFFECTIVENESS REPORT #7 (SUMMARY OF FINDINGS)
The Negligent-Operator Treatment Evaluation System (NOTES) has provided decision makers with biennial cost-effectiveness analyses of the Department of Motor Vehicles' negligent-operator program. This report summarizes the results of the seventh and final impact evaluation of the treatment system. The negligent-operator program consists of four levels: (1) warning letter; (2) notice of intent to suspend; (3) probation hearing; and (4) probation-violator suspension. The evaluation was based on the accumulated post-treatment records of 338,743 violators who entered NOTES between May 1991 and October 1994 and were assigned to one of the three lower-level negligent operator programs or to a no-treatment control group. Level 4 was evaluated indirectly using data from Level 3 groups. At Levels 1 and 2, violators with evidence on their records of alcohol involvement received specially tailored alcohol materials. Major findings are as follows: All four program levels produced statistically significant reductions in traffic citations. The treatments at all program levels except Level 2 resulted in statistically significant reductions in accidents. There was some evidence that the increased use of license suspensions among drivers attending Level-3 probation hearings led to an increase in the effectiveness of the treatment. There was no indication that the introduction of telephone hearings at Level 3 had any adverse impact on traffic safety. At Level 3 there was statistically significant evidence that drivers with prior citations for driving while suspended were less responsive to the treatment (with respect to subsequent accident and citation involvement and hearing attendance).

Supplemental Notes:
- This report is the last in a series which originally began with the creation of the Post Licensing Control Reporting and Evaluation System (PLCRES) in 1976 and was extended in 1983 by a modified version of that system (Negligent Operator Treatment Evaluation System).
