THE EFFECTS OF A TRAFFIC SAFETY FILM OR A DRIVE TEST WITH COUNSELING SESSION FOR RENEWAL DRIVERS LICENSE APPLICANTS WITH POOR PRIOR RECORDS

The purpose of the present study was to evaluate the effects of more indepth renewal procedures for applicants with poor prior three year accident and conviction records. Renewal applicants with poor records who were required to take a longer written test which covered both law and "safe driving" items and to view a film focusing on defensive driving showed no significant treatment effects on subsequent accidents or convictions (p is greater than .05). Similar non-significant results occurred for applicants with poor records who were required to take the new written test and a diagnostic drive test with counseling sessions. Both film and drive test group subjects showed a directional reduction in convictions and a directional increase in fatal and injury accidents. The increase in fatal and injury accidents and decrease in convictions among drive test subjects was significant at the .10 level. When only drivers who completed the intended treatment and were relicensed were compared (91% of the treatment, and 97% of the control group) a significant reduction in convictions was found among applicants who were given the diagnostic drive test (p is less than .05). This result is considered inconclusive because of the self-selected nature of the subjects eliminated from both groups. Performance on the diagnostic drive test was not significantly correlated with either prior or subsequent records of accidents or convictions. While the present study and a number of related projects for renewal applicants with good records have yielded largely neutral or negative results, it would be premature to conclude that no system of differential licensing could have a positive effect on traffic safety. The results obtained are specific to the programs tested; effective programs could yet be found. /Author/
