When Someone With Dementia Should Stop Driving

Families agonise over this for months, so here is the question that resolves most cases: would you put your own child in that car, with them driving?

When the honest answer is no, the time has come. Everything else is negotiation with yourself.

A diagnosis alone does not mean someone must stop immediately, and in the earliest stage many people drive safely for a while. But dementia is progressive, so the question is not whether driving ends but whether it ends by decision or by collision.

Getting lost on a familiar route, which is the one that most alarms families and rightly so. Slower reactions, or missing a stop sign or signal. Confusing the pedals. Drifting between lanes.

The evidence you can gather without being in the car is often clearer. New dents and scrapes appearing without explanation. Paint transfer on the bodywork. Insurance claims you did not know about. A neighbour mentioning the car was parked oddly. Someone becoming anxious about driving, or quietly avoiding motorways, night driving or unfamiliar places, which is often the person themselves knowing before anyone says it.

Daytime only. No motorways. A one mile radius. These feel like reasonable compromises and are mostly denial with a rule attached, because they depend on the person remembering and applying a restriction, which is precisely the ability that is failing.

They are worth something as a short bridge while you arrange alternatives. They are not a destination.

The most useful thing a family can do is not have this argument themselves. A physician saying I cannot recommend that you continue driving carries authority that a son or daughter does not, and it moves you from opponent to ally.

Ask the doctor in advance, ideally without the person present, so it comes as a medical recommendation rather than something a family arranged. Many states also have a medical referral process through their licensing authority, and a formal re-examination often ends the matter without the family being the cause.

Talking generally fails where removal succeeds. The car goes to a relative's house, or is sold, or develops a fault that is never quite fixed. Keys disappear. A mechanic can disable a vehicle discreetly.

This feels dishonest and families struggle with it. Weigh it against the alternative, which is a person with impaired judgement in charge of a car on a road with other people's children on it.

Driving is independence, and taking it without replacing it produces isolation, which accelerates decline. This is the part families skip and then wonder why the mood collapsed.

Arrange the specific journeys that mattered: the weekly shop, church, the friend on the other side of town, the appointment. Set up accounts and payment in advance so using them requires no arranging. Local senior transport schemes exist in most areas and are underused.

Companion care often starts here, for exactly this reason. Someone who drives them to the places they used to drive themselves keeps the life rather than only the safety.
