Abstract
Efforts to reduce accidents and violations by means of education, training, counseling and other "psychological" methods are reviewed. In general, formal programs such as high school driver education, group therapy, and communitywide safety drives have yet to demonstrate effectiveness, while such techniques as warning letters, interviews, and probation do show some promise. Accident-producing behaviour is modifiable, but the best methods have yet to be researched; there are probably great differences in accident reduction and cost effectiveness.
