Summary
This study addresses the disproportionate involvement of young drivers (ages 16–20) in fatal motor vehicle crashes, aiming to identify specific driving situations that elevate their risk. While young drivers constitute a small percentage of licensed drivers, they are overrepresented in fatal crash statistics. Although Graduated Driver Licensing (GDL) programs are effective for teens, most state provisions do not extend to novices aged 18–20. The research seeks to pinpoint high-risk scenarios to inform the refinement of GDL programs and the development of targeted driver education and training materials. The researchers conducted quasi-induced exposure analyses using five years (2013–2017) of data from the Fatality Analysis Reporting System (FARS). The study focused on multi-vehicle fatal crashes involving drivers aged 16–20 and a comparison group of 35-year-old drivers. Drivers under 16 were excluded due to small sample sizes. The analysis included 2,980 drivers from 2,801 crashes, selecting only those with fewer than six vehicles and a single identified contributing factor. Crash Involvement Ratios (CIRs) were calculated to determine over- or under-involvement, comparing the likelihood of having a contributing factor against the 35-year-old baseline using logistic regression. Statistical significance was defined as p < .05, and CIRs were only reported for samples of 20 or more drivers. The results indicate that young drivers were significantly more likely to have contributing factors in fatal crashes than 35-year-old drivers, with risk remaining elevated even at ages 19 and 20. Three specific situations were identified as particularly hazardous for young drivers. First, young drivers were significantly more likely to have contributing factors on two-lane roadways compared to 35-year-olds, whereas this elevated risk on roadways with three or more lanes was only significant for 20-year-olds. Second, young drivers faced increased risk in environments with no traffic control and at stop signs, particularly for 17- and 18-year-olds; no increased risk was found at traffic signals. Third, young drivers were at highest risk when the initial impact occurred on the right side of their vehicle, especially for those aged 17–19. This suggests that maneuvers resulting in right-side impacts, such as left turns, are particularly risky for this demographic. The study concludes that two-lane roadways, intersections with stop signs, and situations leading to right-side impacts represent heightened risks for young novice drivers. These findings provide actionable data for parents, driver educators, and policymakers to tailor supervised practice and educational materials. By focusing training on these specific hazardous scenarios, stakeholders can better prepare young drivers for the challenges they face on the road, potentially reducing fatal crash involvement among this vulnerable population.
Key finding
Young drivers are at heightened risk of having contributing factors in fatal crashes specifically on two-lane roadways, at intersections with stop signs, and in situations resulting in right-side impacts like left turns.
