According to the Centers for Disease Control and Prevention, inexperienced drivers are a significant public health problem. Motor vehicle accidents is the leading cause of death of young adults between age 15 and 20. CDC. Teen Drivers: Fact Sheet.
Graduated driver licensing (GDL) laws require inexperienced drivers to satisfy one or more requirements before being granted full privileges to operate a motor vehicle without supervision. For example, a common feature of these programs is the issuance of a provisional license authorizing an inexperienced driver to operate a vehicle exclusively under the supervision of a fully licensed adult. In many instances, inexperienced drivers must also adhere for a period of time to other restrictions such as not driving at night or with more than one passenger. If an inexperienced driver satisfies the requirements of the provisional period, a fully unrestricted license may be issued. For examples of graduated license laws, see Fla. Stat. § 322.16 (Florida), MCLS § 257.310(e)( Michigan), and ORC Ann. 4507.05(Ohio).
Harling et al. systematically reviewed fifteen studies measuring the impact of graduated driver licensing programs on one or more of the following: overall crashes, crashes with an injury, hospitalization, fatal crashes, crashes at night, alcohol-related crashes, injured teen passengers, convictions and license suspensions, and property damage. Hartling L et al. Graduated driver licensing for reducing motor vehicle crashes among young drivers. Cochrane Database Syst Rev. 2004;(2):CD003300. The review found a median reduction of 31 percent in crash rates among 16 year-old drivers following the adoption of GDL laws. These findings indicate that GDL programs are effective reducing crashes among novice drivers.
A Public Health Law Research Program “Evidence Brief” summarizes the research assessing the effect of a specific law or policy on public health.
Evidence Briefs are prepared by the staff of the National Program Office. Briefs are based on systematic literature reviews conducted by highly-regarded scholars and published by credible organizations or peer-reviewed journals. Evidence Briefs digest the best available evidence, but readers should bear in mind that even the best evidence may have limitations or deficiencies.
The evidence briefs are organized by topic and intervention. Each law or policy is classified as “effective,” “uncertain” or “harmful,” according to the conclusions of the expert reviewers. These are not independent conclusions of the NPO, nor do they reflect the views of the Robert Wood Johnson Foundation.
Each Evidence Brief includes links to the study on which it is based. In many cases, the study is available in the public domain, but access to some may require a subscription.
