The PLCRES (Post Licensing Control Reporting and Evaluation System) is tasked with evaluating the costs and traffic safety impacts of the four negligent operator treatments --Warning Letter (W/L), Group Educational Meeting (GEM), Individual Hearing (I/H), and Probation Violator Hearing (P/V). Data collection began February, 1975. This represents the first in a series of published evaluative reports. The study utilizes ongoing random assignments. When the drivers are found to be eligible for a given treatment, the computer randomly assign them to treatment vs. control (treatment withheld) conditions. The W/L, as well as the GEM, were projected to save 4.56 accidents per 1,000 drivers treated. These represent best estimates and are not statistically significant. The I/H was projected to save 20.1 accidents per 1,000 drivers treated, and the P/V was projected to save 9.67 accidents per 1,000 drivers. Both of these latter estimates were statistically significant. Each of the four treatments causes a statistically significant and substantial reduction in convictions. Cost-benefit estimates using several estimates using several estimates of costs, and benefits from accident reduction, indicate that the cost-benefit status of the GEM and P/V is equivocal, but the I/H is generally projected to be cost-beneficial and the W/L is consistently projected to be cost-beneficial. The negligent operator program taken as a whole was projected to be cost-beneficial, preventing an estimated 1,200 accidents annually. Future PLCRES reports will be issued annually and will update the present finings.
