Driving requires constant focus, quick decision-making, and the ability to regulate impulses—all of which can be challenging for individuals with ADHD. Research suggests that people with ADHD may be at a higher risk of traffic accidents due to symptoms like inattention, impulsivity, and distractibility.
After hitting a deer last summer on the way home from a long road trip, I started wondering: What does science and research say about ADHDers and driving?

How ADHD Symptoms Affect Driving
ADHD is characterized by inattention, impulsivity, and hyperactivity—traits that can make driving more difficult:
Inattention: Losing focus for even a few seconds can mean missing critical road signs, traffic signals, or sudden stops ahead.
Impulsivity: Making quick, uncalculated decisions—like merging suddenly or accelerating at a yellow light—can increase crash risk.
Hyperactivity: Feeling restless or fidgety might lead to unnecessary movements, adjusting controls too frequently, or failing to stay seated calmly, all of which can impact reaction time.
The Research: ADHD and Traffic Accidents
Multiple studies confirm that ADHD is linked to a higher likelihood of car accidents:
A study in JAMA Psychiatry found that individuals with ADHD are 45%–47% more likely to be involved in severe transport accidents than those without ADHD.
Research from the Children's Hospital of Philadelphia shows that newly licensed drivers with ADHD have a 37% higher crash risk than their non-ADHD peers.
A study by Columbia University found that older adults with ADHD also experience significantly higher crash rates, suggesting that the risks persist throughout life.
Why ADHD Drivers Face Higher Risks
Several factors contribute to the increased likelihood of accidents:
Distractibility: A wandering mind can lead to missed turns, overlooked stop signs, or delayed reactions.
Impulsive Behavior: Sudden lane changes, speeding, and risky maneuvers are more common in ADHD drivers.
Difficulty Following Routines: Checking mirrors, signaling, and following structured driving habits can be inconsistent.
How ADHD Drivers Can Stay Safe on the Road
Though the risks are real, there are strategies to help ADHD drivers improve their safety:
Defensive Driving Courses: Specialized training programs for ADHD drivers can teach techniques to manage impulsivity and maintain awareness.
Limiting Distractions: Using "Do Not Disturb" phone settings or apps that block notifications can help minimize distractions.
Mindfulness and Driving Routines: Practicing mindfulness techniques or creating structured pre-driving checklists can reinforce good habits.
ADHD and Road Safety
Having ADHD doesn’t mean you can’t be a safe driver—it just means you may need extra strategies to stay focused and in control. By understanding the risks and taking proactive steps, ADHD drivers can reduce their chances of accidents and improve their overall driving experience.
If you or someone you know has ADHD and drives, consider implementing these tips to create a safer and less stressful time behind the wheel.
