The objective of these studies has been to provide driver license officials, epidemiologists, traffic safety researchers, and organizations involved in risk assessment and risk management with actuarial data on driver accident risk profiles. The latest report in this series is entitled An Inventory of California Driver Accident Risk Factors . This new report presents extensive driver record information on a random sample of over 200,000 California drivers and driver record histories covering 12 years of driving.
Men have poorer records than do women, largely because they drive more miles.
For both sexes, driver age is related to accidents and citations. Teen drivers have the highest accident-involvement and citation rates. As drivers age, their accident-involvement rate decreases through about age 69 and then increases somewhat. As drivers age, their citation rate decreases substantially even at very advanced age. Accident risk increases as a function of the number of accidents and citations on the driver's prior record.
