Are people with ADHD more likely to have car accidents?

Driving is full of distractions, from cellphones to other drivers on the road. But for adults and teens dealing with symptoms of ADHD, like inattention and impulsivity, those disruptions can make driving especially risky.

On average, adult drivers with ADHD in one study got into and people with severe averaged one accident a year. A large study in JAMA Pediatrics found that teen and young adult drivers with ADHD were compared to drivers without ADHD. Only 12.1% of the study participants were taking ADHD medication at the time, though. This highlights the potential risk that untreated ADHD can have on driving.

In fact, are crucial for keeping drivers with ADHD more focused and alert on the road. A study in JAMA Psychiatry compared medical records with insurance claims and found that 22% of the crashes in the study period .

A 2026 review found that adults who were with stimulant medication got into car crashes more often. Researchers grouped untreated ADHD with other risky driving behaviors, such as driving under the influence of cannabis or alcohol, driving while sleepy, and speeding.

鈥淣ot only are [people with untreated ADHD] involved in more car accidents, more fender benders, but they鈥檙e more likely to have physical injuries as a result of the car accidents,鈥 says , director of the Adult Attention Deficit Disorder Center of Maryland. 鈥淪o you have to think about this as not only a risk to the untreated ADHD individuals, but it鈥檚 a risk for every car that happens to be around them.鈥

Of course, just because you have ADHD doesn鈥檛 mean you鈥檒l get into accidents or that you can鈥檛 be safe on the road, notes , an education attorney with ADHD who represents adolescents in school as well as in criminal and juvenile cases. 鈥淥utward manifestations of ADHD vary depending on the person,鈥 he says. 鈥淭here are individuals with ADHD who are very good drivers and have clean driving histories and few or no accidents.鈥

Becoming a safe driver with ADHD is possible at any age. It often comes down to practicing good driving habits. These range from being prepared for 鈥渉ighway hypnosis鈥 to consulting with a doctor to determine the best time to take ADHD medication. shares what to know to stay safe behind the wheel.

What ADHD looks like on the road

In several studies, researchers monitored , using in-car cameras or driving simulators. They found that adult drivers with ADHD have less stable control of the car. They don鈥檛 practice defensive driving as much. They speed up and slow down more quickly, and they switch lanes more often.

Other ways ADHD may affect your driving include:

  • Picking up your phone every time you get a notification
  • Driving through red lights and stop signs you didn鈥檛 notice
  • Feeling road rage, which leads you to race other cars or make quick lane changes
  • Getting distracted and braking quickly to avoid hitting the car ahead of you
  • Getting lost in a daydream and not realizing you鈥檙e driving too fast or too slow
  • Forgetting your driver鈥檚 license at home

According to Goodman, inattentiveness is the main ADHD trait that contributes to these driving risks. It can cause you to be less aware of signs and what鈥檚 happening on the road. So every time you get distracted 鈥 by a text notification, a funny billboard, or a story a passenger is telling 鈥 you can have a hard time reacting to other cars, people, and changes in the road.

Driving environments can also affect attention. Long and boring roads 鈥 even new ones 鈥 may pose a focus challenge, says leader of the Applied Driver Assessment Performance and Training Group at the Virginia Tech Transportation Institute. In fact, drivers with ADHD may focus better on more complex roads. 鈥淭hey actually do pretty well in more complex environments,鈥 Klauer explains. 鈥淭hey鈥檙e able to focus better than when there鈥檚 not a lot going on.鈥

ADHD, , and impulsivity can also lead to unsafe driving. 鈥淚f you get pissed about the guy in front of you who鈥檚 not going fast enough, you may suddenly change your lane without putting on a blinker and without looking, and then end up side-swiping somebody,鈥 Goodman says. 鈥淭hat鈥檚 not an inattentive error. That鈥檚 an impulsivity error that grows out of emotional reactivity.鈥

From a neurobiological perspective, it鈥檚 not completely clear what鈥檚 happening in the ADHD brain to affect driving. According to Klauer, one hypothesis is that while adolescents with ADHD look around them, they don鈥檛 necessarily process what they see in the same way that neurotypical teens do.

But more research is needed to fully understand how ADHD and driving accidents are related. 鈥淭here are several studies out there, but we really are just touching the surface in terms of truly understanding what's going on,鈥 Klauer says.

How ADHD affects driving at every age

In general, teens and young adults are at a , according to Klauer. That鈥檚 even more true when the drivers have ADHD. Young drivers with ADHD are also , according to research in the Journal of Adolescent Health.

And while neurotypical people typically become safer drivers as they enter adulthood, research suggests that the risk of accidents stays relatively high for people with ADHD. In fact, drivers with ADHD, ages 18 to 46, are including fatal ones.

Adults with ADHD who are over age 65 may also face increased driving risks. A study of adults ages 65 to 79 years found that those with ADHD were twice as likely to report getting traffic tickets and 74% more likely to get into car crashes compared to drivers without ADHD.

Tips for drivers with ADHD

In addition to seeking diagnosis and treatment, drivers with ADHD can take steps to practice safer driving. Experts recommend the following tips for staying alert and focused on the road.

1. Hide your phone, or better yet, turn it off. Keeping a phone nearby can be one of the most dangerous distractions for a driver with ADHD, Goodman says. Stash your phone in the glove compartment or in a backseat pocket, so you can鈥檛 reach for it while behind the wheel. 鈥淵ou have to get the phone out of your hand, out of your reach, and out of your visual sight,鈥 Goodman advises.

There are also apps that lock down a phone when motion is detected, like when you start driving. Apple and Android phones have built-in 鈥渄o not disturb鈥 and auto-reply features for drivers. And apps like DriveOff and DriveScribe can stop you from accessing texts and apps while driving.

2. Time your medications. If you use an ADHD stimulant, it鈥檚 important to Even the longest-lasting stimulants might not stay in your system long enough to help you drive at night. So you might benefit from a booster dose before you get behind the wheel. Work with your health care provider to find the best approach to your medication.

3. Beware 鈥渉ighway hypnosis.鈥 When you鈥檙e you might zone out and forget whole stretches of the road. This is called highway hypnosis. And it can be dangerous because you might not notice obstacles, or if you鈥檙e driving too fast or too slow. You can by taking frequent breaks from driving. You can also listen to music and keep yourself active, like by chewing gum.

4. Avoid big carpools. With several people in the car, you might get pulled into conversations or feel overwhelmed by all the noise. If other passengers tend to be a distraction for you, Goodman recommends limiting the number of people you agree to drive. And if you鈥檙e driving a large group, consider letting someone else take the wheel.

5. Check your route ahead of time. Do some homework to avoid having to check your phone or GPS for directions in the middle of a drive. If you鈥檙e headed to a new place, preview the route ahead of time. Klauer even recommends using Google Earth to look for areas that may be tricky to maneuver 鈥 or to find parking spots ahead of time.

6. Practice with new drivers. According to Klauer, it鈥檚 best to . The more supervised practice 鈥 in as many different settings as possible 鈥 the better. And don鈥檛 forget to practice night driving. 鈥淟earning to drive is a skill that requires practice, and while the mechanics of learning to drive come very quickly, nuances of learning to drive do not,鈥 Klauer points out.

Research shows that teens are more likely to have accidents when they鈥檙e alone in the car. So Klauer recommends using phone apps to understand how your ADHD teen is driving when they鈥檙e alone. Apps like Life360 can track their speed, how many times they pick up their phone, and how often they brake quickly.

If you need outside help, many driving schools now offer training programs for drivers with ADHD.
