Long-Term Changes in Crash Rates After Introduction of a Graduated Driver Licensing Decal Provision
New Jersey (NJ) implemented the first Graduated Driver Licensing (GDL) decal provision in the U.S. in May 2010. An initial study reported a 1-year post-decal decrease in the crash rate among NJ intermediate drivers aged <21 years. Longer-term analysis is critical for policymakers in other states considering whether to implement a decal provision. This study, published in the American Journal of Public Health, evaluates the longer-term (2-year) effect of NJ’s decal provision on overall and age-specific crash rates of young drivers with intermediate licenses.
