Abstract

In July 1998, California passed one of the U.S.'s toughest graduated driver licensing (GDL) laws. This study evaluates the effect of the state's GDL provisions-a strict teen passenger restriction and nighttime driving limitation-on alcohol-related crashes. While prior studies do not clearly demonstrate that GDL leads to alcohol-related crash reductions among teens, results in California show sharp reductions in had been drinking crash rates of 16-year-olds, especially in comparison to crash rates for a control series of 19-year-old drivers. The reduction in the had been drinking driver crash rate (per 100,000 drivers) for 16-year-olds from pre-GDL to one year post GDL is 16.0%; during the second post GDL year, it is 13.1%. When crash rates are standardized to control for crash trends of 19-year-olds, reductions are 21.0% and 22.0% in post GDL periods.
