Georgia's Teenage and Adult Driver Responsibility Act

An Evidence-Based Practice

Description

The Georgia General Assembly enacted the Teenage and Adult Drivers Responsibility Act (TADRA) in 1997. The comprehensive legislative package aimed to reduce fatal crashes among teenage drivers by targeting three major contributors to fatal crashes by teenage motorists: inexperience, driving under the influence of alcohol, and excessive speeding. TADRA adopted every graduated driver's licensing provision recommended by the National Highway Traffic Safety Administration, a "zero tolerance" policy of underage impaired drivers, and a process of automatic license revocation for driving more than 25 miles per hour over the posted limit. The graduated license includes the following three stages: (1) an instructional permit; (2) an intermediate license with restrictions on the time of day and they type of passenger the driver may carry; and (3) a full license awarded to drivers aged 18 and older who have incurred no major traffic convictions during the previous 12 months.

Goal / Mission

The goal of TADRA is to reduce fatal crashes among teenage drivers.

Impact

After the implementation of TADRA, speed-related fatal crashes were cut by 42%, and alcohol-related fatal crashes decreased nearly 60%.

Results / Accomplishments

The impact of TADRA was studied using a pre-and post-comparison. During the time period before the law was enacted, 317 Georgia drivers aged 15 were involved in a fatal crash (57/100,000 person-years) compared to 230 in the post-enactment period (36/100,000 person-years; risk ratio 0.63; 95% CI 0.53 to 0.75), a 37% reduction. Speed-related fatal crashes were significantly cut by 49% (RR 0.51; 95% CI 0.38 to 0.69) and alcohol-related fatal crashes significantly decreased by 62% (RR 0.38; 95% CI 0.18 to 0.80), without displacing fatal crashes to older age groups. These reductions greatly exceeded those noted in the three comparison states (Alabama, Tennessee, and South Carolina).
