Long Term Impacts of California's Graduated Licensing Law of 1998

With fatal and injury crash data from California's Statewide Integrated Traffic Records System (SWITRS), this study used standard regression analysis as well as the Bai-Perron stochastic multiple structural break model to determine the effect of the law on teen-age passengers and crash rates of 16 year-old drivers. The authors found that in the four and one-half years following implementation of the new law, crashes caused by 16 year-old drivers decreased by 11% and the average number of teen-age passengers carried by 16 year-olds decreased by approximately 31%. The combination of these two decreases resulted in the saving of 29 lives and the prevention of 2,632 injuries.
