Dementia and driving: how this decision actually gets made

By Todd Whitehurst · Reviewed August 2026

A dementia diagnosis doesn't mean driving has to stop immediately — some people continue driving safely in early stages. But cognitive decline does progressively affect driving safety, and there are legitimate ways to address it that don't involve family members taking unilateral, forceful, or deceptive action.

Warning signs worth watching for

Getting lost on a familiar route, or forgetting the destination mid-drive
New dents, scrapes, or increasingly frequent near-misses
Confusing the gas and brake pedals, or slow reactions to sudden situations
Missing stop signs, traffic signals, or making poor decisions in traffic
Driving noticeably too slowly or too fast for conditions
Becoming confused, agitated, or disoriented while driving

One odd incident isn't necessarily conclusive — but a pattern, or any incident that put someone at real risk, is worth acting on rather than waiting to see if it happens again.

How this decision legitimately gets made

Raise it with the physician. A doctor can factor driving safety into ongoing evaluations and, if warranted, make a formal recommendation — which often carries more weight than the same message from family.
Request a professional driving evaluation. Occupational therapy driving rehabilitation specialists conduct assessments that go beyond a family member's observation, and can offer an objective answer either way.
Understand your state's process. Driving privileges are governed by state law, not family decision — some states allow physicians or family members to request a DMV re-evaluation. Rules vary significantly by state, so check with your state's DMV directly.
Plan transportation alternatives in advance, before the driving stops, so the change doesn't also mean sudden isolation — rides from family, senior transportation services, or rideshare options are worth lining up ahead of time.

What not to do: Disabling the car, hiding the keys without a real plan behind it, or deceiving your parent about why the car is gone can damage trust and doesn't resolve the underlying safety question through a legitimate channel. These approaches also don't address a parent's legal right to their license unless it's actually been revoked or restricted by the state. Working through a physician's recommendation or the DMV process addresses both the safety concern and the legal reality directly.

Circumstances that may require urgent action

Your parent has already been in an accident, however minor, that may be related to cognitive changes
Your parent has gotten lost while driving and needed to be located
You've directly witnessed clearly unsafe driving — confusing pedals, running lights, extreme confusion behind the wheel

In these situations, addressing it immediately — including contacting the physician right away rather than waiting for a routine visit — is appropriate.

Frequently asked

Does a dementia diagnosis mean my parent has to stop driving right away?

Not necessarily. Some people in early-stage dementia can continue driving safely for a period of time. A physician or driving evaluation specialist is best positioned to assess this, ideally with ongoing monitoring rather than a one-time judgment.

Can I just take the keys away myself?

This is understandable as an instinct, but it can escalate conflict and doesn't address the underlying legal reality that driving privileges are governed by the state, not by family decision alone. Working through a physician's recommendation or the state DMV's evaluation process is a more durable, legitimate path.

What if my parent gets angry when driving comes up?

That's a common reaction, since driving is closely tied to independence. Starting the Conversation covers approaches that tend to reduce conflict, and involving a physician as the one delivering the recommendation can sometimes land better than it coming from family alone.
