The motor vehicle skills, risks, and accidents in 25 young adults with ADHD were compared with 23 non-ADHD adult control subjects, aged 17 to 30 years, at the Departments of Psychiatry and Neurology, University of Massachusetts Medical Center, Worcester, MA. ADHD young adults were twice as likely to be cited for unlawful speeding, had more crashes, more accidents involving bodily injury, more likely to have licenses suspended, and poorer driving habits and performance despite adequate driving knowledge, when compared to controls. 
COMMENT. This study confirms previous reports of an increased risk of motor vehicle accidents and injury among ADHD young adults. The findings indicate the need for continued treatment and supervision of adolescents with ADHD into adulthood, particularly in relation to self-regulation of motor control and lessening of impulsive behavior.
