Teenagers and driving

Abstract

In the United States, motor vehicle crashes are a leading cause of injury and death in adolescents. Driving is a complex task that requires integrating several cognitive processes. However, the prefrontal cortex, which is the brain area responsible for these higher-level functions, is not fully developed in adolescents. Slow development of the prefrontal cortex further contributes to teens’ impulsivity and risk-taking behavior. This chapter presents research on the risky behaviors undertaken by teen drivers, including cell phone use, peer passengers, speeding, inconsistent seat belt use, alcohol/substance use, and sleep deprivation. The chapter then outlines existing intervention efforts to reduce car crash injury and death among teens, such as graduated driver's licensing laws and regulations regarding distracted and impaired driving. Finally, the authors provide recommendations for parents and health care providers to address teen driving safety.
