Final answer:
Crash risk is high during the first year that teenagers are eligible to drive due to their lack of experience and potentially risky driving behaviors.
Step-by-step explanation:
According to research, crash risk is high for teenagers during their first year of eligibility to drive. This is because new drivers lack experience and may not yet have developed good driving habits or judgement. For example, a study published in the Journal of Pediatric Psychology found that risky driving behaviors were more common among adolescents and young adults with ADHD, indicating that inattention and impulsivity can contribute to higher crash risk.
