POST LICENSING CONTROL & EVALUATION SYSTEM: NEGLIGENT OPERATOR PROGRAM COST & EFFECTIVENESS (FEBRUARY 1979)

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) are presented. The warning letter was projected to save 1.24 accidents per 1,000 drivers treated. While this effect size is not statistically significant, the w/l is so inexpensive that sample results project it to be cost-benefical, with an estimated cost of $669 for each accident prevented. The remaining treatments had statistically significant impacts on accidents. The gem is projected to save 17.12 accidents per 1,000 drivers, at a cost of $871 per prevented accident. The i/h is projected to save 18.77 accidents per 1,000 drivers at a cost of $2,305 per accident saved. The p/v is projected to save 9.16 accidents per 1,000 drivers treated, at a relatively high estimated cost of $6,139 per accident saved. The projected effect of all treatments combined was 1,155, accidents prevented per year. The w/l, gem, i/h, and all treatments as a package are cost-beneficial, but findings for the p/v on this are equivocal. Each treatment caused a statistically significant, substantial reduction in convictions.
