This study examined the effects of Georgia's Graduated Licensing Law on fatal crashes among 16 year-old drivers. After the first five and one-half years following the enactment of Georgia's GDL law, (known as the Teenage and Adult Driver Responsibility Act (TADRA) fatal crashes of 16 year old drivers were 36.8 percent lower than during the five and one-half years prior to enactment.
This finding suggests that TADRA was effective in reducing fatal crashes among 16 year-old drivers.
