Evaluating the effectiveness of the decal provision of New Jersey's graduated driver licensing law

The Foundation's program, Public Health Law Research: Making the Case for Laws That Improve Health, was designed to build the evidence for public health law and policy, translate research findings into practical tools to increase the support for and use of law by policy makers and public health practitioners, and to translate findings to other fields and venues to improve and protect health.Motor vehicle crashes are the leading cause of teen death and injury. This Children's Hospital of Philadelphia (CHOP) study will evaluate a New Jersey Graduated Driver Licensing law (Kyleigh's Law passed 5/1/10), which requires probationary teen drivers to display a decal on the vehicle's license plate, making them easily identifiable to police and thereby making it easier for police to enforce: (1) restrictions on the number of passengers less than 21 years of age allowed in the vehicle without parent accompaniment; (2) a ban on driving between the hours of 11:01 p.m. and 5 a.m.; (3) a ban on driver use of interactive wireless communication devices; and (4) a required seat belt use for all vehicle occupants. The study, conducted by the Center for Injury Research and Prevention at The Children's Hospital of Philadelphia analyzes existing NJ licensing and citation data to compare the number and rate of citations issued to and number and rate of police-reported and fatal crashes involving NJ teen probationary drivers before and after the law went into effect. The study also will present findings at highway safety research conferences and webinars to highway safety and/or public health policy makers as well as peer-reviewed publications and disseminate findings via teendriversource.org. This study is an example of an intervention study examining the effect of a legal intervention on health outcomes, which will include focusing on mediating or moderating factors associated with enforcement, in order to fully illuminate the way in which the law operates.
