摘要：	California's 1998 graduated driver licensing program was implemented to reduce the high crash risk of teenage drivers. Monthly per capita crash rates for 15-to-17-year-olds were analyzed using time series analysis. No overall reduction in total crashes or fatal/injury crashes was found immediately following program implementation or beginning 6 months later. The 12-month nighttime restriction was associated with significant sudden-permanent reductions of 0.44%in total crashes marginally significant 0.45%in nighttime fatal/injury crashes. The 6-month passenger restriction was associated with reductions of 2.52%and 6.43%in total and fatal/injury teen passenger crashes, respectively. The fact that no overall reductions in crashes, and only small reductions in crashes associated with the restrictions, were found is not surprising giving findings that teens and parents were either already practicing program requirements prior to implementation, or not fully complying with the program requirements afterwards. The findings provide support for passenger and nighttime restrictions.
