Abstract
As part of broader research efforts to understand the factors contributing to crashes involving younger drivers, it is important to characterize the crash contributing factors of the at-fault younger drivers. This study applied latent class analysis (LCA) to identify subgroups with statistically distinct patterns in the contributing factors of fatal crashes involving young male and female drivers in Alabama. Model estimation results reveal that crashes on rural roads are a serious issue in Alabama. It was also observed that a high proportion of the young driver fatal crashes occurred on weekends and closer to the driver’s place of residence. Interestingly, the proportion of crashes involving speeding increased with age for males and decreased with age for females. In general, younger female drivers (15–18 years) were more likely to be involved in speed and aggressive driving related fatal crashes than their male counterparts. Also, fatal crashes involving driving under influence (DUI) increase with age for both male and female drivers, with a significant increase for drivers between 19 and 21 years of age. These study findings suggest that specific attention should be focused towards younger drivers in rural communities and communities with lower socioeconomic opportunities. Targeted education and outreach campaigns, combined with appropriate enforcement efforts could meaningfully change the attitudes and behaviors related to road safety.

Summary
Global health data suggest that young people are vulnerable to road crashes. The World Health Organization reports that road crashes are the leading cause of death worldwide among people aged 15–29 years [1]. National-level data indicates that over 4,300 young drivers (aged 15–24) were killed in motor vehicle crashes in the United States during 2016, representing over. There are common assertions as to why younger drivers are more likely to be involved in crashes. Prominent among these assertions is that young drivers are prone to crashes due to life-stage perceptions that are evident in other youth behaviors [3,4,5,6,7]. Younger driver crashes have been attributed to cognitive processes such as underestimation or overestimation of driving skills and perception of risk [6,8,9,10,11,12,13]
