This research report examines how attention deficit hyperactivity disorder (ADHD) can impact distraction and driving safety in teens, using naturalistic driving study data to analyze the frequency of eyes-off-the-road (EOR) instances. This study is one of the first to fully investigate the prevalence of teen drivers’ EOR behaviors and the associated impact on the risk of crashes and near-crashes. The report concludes that teen drivers with ADHD tend to look away from the road more frequently and may be at an elevated risk  for missed hazards. Notably, they found no measurable difference in EOR-related crash risk between teens with and without ADHD.
