Abstract The main objective of this study was to determine if traffic safety materials were effective in reducing the subsequent accident and conviction record of the general driving population. A second objective was to determine the effectiveness of different topics covered by the materials. A third objective was to determine if materials tailored for specific age-sex groups were more effective than non-tailored materials. The results indicated that the materials were not effective in reducing subsequent six month accident and conviction frequencies. In addition, the results indicated that neither the topic nor the tailoring of the material had any effect on subsequent driving record. Lastly, age and sex of the recipient did not moderate the effect of the material on subsequent driving record. It was recommended that the Department not incorporate these safety materials in any of its ongoing operations. The Department's traffic safety dollars would be more wisely spent on developing and evaluating countermeasures other than traffic safety materials of the type evaluated.
