Older Novice Driver Crashes in New Jersey: Informing the Need for Extending Graduated Driver Licensing Restrictions

In contrast to most other countries with Graduated Driver Licensing (GDL) systems, only a few U.S. jurisdictions currently extend GDL restrictions to drivers licensed at age 18 or older. However, several recent studies have found that a substantial proportion of drivers are getting licensed at older ages, and further, that later licensure occurs disproportionately among low-income and minority drivers. A current topic of discussion in the traffic safety community is whether standard GDL policies that are applied in the U.S. for younger novice drivers should be applied to older novices not presently covered by them. The goal of this study is to evaluate whether there is epidemiologic evidence to support— from a crash-reduction perspective—adoption of passenger and nighttime restrictions for newly-licensed drivers aged 18 years and older. This longitudinal study examined how overall, injury, nighttime, and passenger crashes differ for novice drivers licensed at different ages over the initial few years of licensure. New Jersey is already unique among states in that the minimum age for independent driving is 17, and all novice drivers under age 21 are covered by full GDL policies (e.g., learner period, nighttime restrictions, multiple-passenger restriction). Given that 18- to 20-year-old novice drivers in New Jersey are already covered under New Jersey’s GDL system, this study is unique in its ability to address the existing benefit of current restrictions among these drivers. Examination of novice drivers age 21 and older will address whether there could be a benefit from implementing these restrictions among these drivers.
