Summary
This study investigates the timing of driver’s license acquisition among young people in the United States and identifies the primary reasons for delays in licensure. The research was motivated by conflicting evidence regarding the safety impacts of Graduated Driver Licensing (GDL) systems on 18- and 19-year-olds. While GDL has proven effective for younger teens, some researchers hypothesized that young people might delay obtaining licenses until age 18 to avoid GDL restrictions, potentially resulting in less experienced and higher-risk novice drivers. This study aimed to determine the extent of such delays and whether GDL avoidance was a significant motivator. The researchers conducted an online survey of a representative sample of 1,039 young adults aged 18 to 20 in 2012. Data were weighted to reflect the national population of this age group. The questionnaire collected information on licensure status, the specific age at which respondents obtained their licenses or learner’s permits, and self-reported reasons for any delays. Multivariable logistic regression was used to analyze associations between demographic factors—such as income, race, and region—and the timing of licensure. The findings revealed widespread delays in licensure: only 44% of respondents obtained a license within one year of their state’s minimum age, and only 54% were licensed before turning 18. Significant disparities existed based on socioeconomic status. Among those from households earning $60,000 or more, 72% were licensed before age 18, compared to only 25% of those from households earning less than $20,000. Non-Hispanic white respondents were also significantly more likely to be licensed early than Black or Hispanic respondents, even after controlling for income. Crucially, the study found little evidence that GDL systems drove these delays. The most common reasons for delaying licensure were lack of access to a car, the ability to get around without driving, and the costs associated with driving. Fewer than one-quarter of respondents cited GDL requirements or restrictions as important factors. Furthermore, among those not licensed by 18, fewer than one-third obtained a license before turning 19, suggesting most were not simply waiting out the GDL period. The study concludes that a substantial minority of young people, particularly those from low-income or minority backgrounds, begin driving without the protective structure of GDL systems. Because these individuals miss the opportunity to gain experience under restricted conditions, they may face higher crash risks. The authors recommend further research into the safety profiles of older novice drivers and the potential benefits of extending GDL protections to drivers aged 18 and older.
Key finding
In a nationally weighted survey of 1,039 U.S. young adults ages 18–20, only 44% obtained a license within 12 months of their state's minimum age and 54% before age 18; delay was strongly associated with low household income and black or Hispanic identity, while GDL avoidance was rarely cited as an important reason for waiting.
