Direct observation of driving behavior is a preferred-source of information, but there is little available at the present time. Driver record data cannot only provide knov, iedge of driving behavior useful in program development. but can point up areas worthy of more direct, detailed observation. The present study t'orms an extension of the previous research in that it presents means and mileage-adjusted means for many types of violation for a large sample analyzed by age. sex, and marital status. In addition, comparisons are made with violations resulting from an accident investigation.
