Driving and Dementia

How dementia affects driving, warning signs that it's no longer safe, how to have the conversation, getting a professional driving evaluation, and finding other ways to get around.

Last reviewed: October 2026

For many older adults, the car keys mean freedom: getting to church, the grocery store, the doctor, or a friend's house without asking anyone for a ride. That's why the question of when to stop driving can be one of the most emotional parts of a dementia diagnosis—for the person and for the family.

A diagnosis of dementia doesn't always mean someone must stop driving that day. But, as the Alzheimer's Association puts it, because driving requires reacting quickly to changing situations, a person living with Alzheimer's will at some point be unable to drive safely. Planning ahead makes that change easier and safer for everyone.

How dementia affects driving

Safe driving draws on many brain skills at once. The National Institute on Aging (NIA) notes that good drivers are alert, think clearly and make good decisions quickly. Dementia can affect:

Memory – forgetting the way to familiar places, or the destination partway through a trip
Judgment and decision-making – poor choices at intersections or when changing lanes
Reaction time – being unable to respond quickly to a surprise, such as a child or car darting out
Attention – trouble handling several things at once, like traffic signs, mirrors and pedestrians
Vision and spatial skills – misjudging distances or lane position

The NIA points out that some people in the early stages can still drive safely at times, and some may manage short, familiar trips during the day but not at night or on a highway. Limiting when and where the person drives can be a step along the way.

The hardest part: people often don't notice

According to the NIA, people with dementia often do not realize they are having driving problems. This lack of awareness is part of the disease (see Anosognosia (Lack of Awareness)). An American Academy of Neurology review found that a person's own rating of their driving was not a useful way to tell whether they were safe—while a caregiver's rating of their driving as marginal or unsafe was a useful warning sign. In other words, family observations matter.

Warning signs it may be time to stop

The NIA and the Alzheimer's Association list signs such as:

Getting lost on familiar routes, or taking far longer than usual on a simple errand
Forgetting where they were going
New dents or scrapes on the car, near misses, or crashes
Two or more traffic tickets or minor accidents, or rising insurance premiums
Ignoring traffic signs or signals; errors at intersections
Driving too fast or too slowly
Poor lane control, drifting, or hitting curbs
Confusing the gas and brake pedals
Becoming angry or confused while driving
Comments from neighbors or friends about unsafe driving
A doctor's recommendation to change driving habits or stop

Tip: Ride along regularly as a passenger, so you can see for yourself how things are going.

Plan ahead—early

The Alzheimer's Association encourages families to talk about "retirement from driving" before it becomes an emergency, ideally while the person is in the early stage and can take part in the plan. Ideas include:

Talk about who will provide rides and how errands will get done.
Involve family and close friends.
Consider a driving agreement or contract, signed in the early stage, that gives a trusted person permission to help the person stop when the time comes. The Alzheimer's Association offers a sample.

Because laws, licenses and insurance can be involved, this is also a good topic to include in Legal Planning.

Get a professional driving evaluation

An objective test can take the pressure off family members. The Alzheimer's Association suggests a comprehensive driving evaluation by an occupational therapy driving rehabilitation specialist. It gives a clearer picture of how the disease is affecting driving, and may include ways to lower risk in the early stage. The American Occupational Therapy Association has a national database of driving specialists, and your doctor or state motor vehicle office may recommend one. The NIA notes that there may be fees.

Know your state's rules

State laws differ. According to the NIA:

Some states automatically revoke a license after a dementia diagnosis.
Others allow a person with a diagnosis to take and pass a driving test.
Many states require retesting when there is reason to believe someone may not be able to drive safely; reports can come from police, medical staff, family members and others.
A few states require doctors to report a dementia diagnosis to the department of motor vehicles.

Check with your state's motor vehicle office for the rules where you live.

How to have the conversation

There's no perfect script, but these tips from the Alzheimer's Association and NIA can help:

Be kind and respectful. Acknowledge how hard this loss is. Giving up driving can feel like giving up independence.
Focus on safety, for the person and for others on the road, and appeal to their sense of responsibility.
Stress the positive and offer specific alternatives.
Ask the doctor to help. A doctor can tell the person not to drive, or write "Do not drive" on a prescription pad that you can show later as a reminder.
Enlist a respected voice, such as a family elder or the family attorney.
Expect more than one conversation, and expect anger. The Alzheimer's Association notes that the disease can impair insight and judgment—if the talk goes badly, don't blame yourself.

If the person keeps driving

The NIA warns that if someone keeps driving when it is no longer safe, someone could be hurt or killed. As a last resort, families may need to:

Hide the car keys
Disable the car or move it out of sight
Sell the car

If you do this, be sure there is reliable, safe transportation in place, so the person doesn't become isolated.

Other ways to get around

Losing the ability to drive doesn't have to mean losing the ability to get out. Options suggested by the NIA and the Alzheimer's Association include:

Rides from family, friends and neighbors (a shared calendar helps)
Taxis and ride services
Free or low-cost senior or disability transportation
Volunteer driver programs through churches and community groups
Home delivery of groceries, meals and prescriptions

To find local services, contact your Area Agency on Aging or the Eldercare Locator (800-677-1116). The NIA also points to Rides in Sight (855-607-4337), a service of the nonprofit ITN America.

Where to get help

Talk with the person's doctor about driving safety at every visit; it's a medical question as much as a family one.
