Start by talking with your spouse directly, in a calm moment, and loop in someone they respect — a doctor, adult child, or attorney — because Alzheimer's disease itself damages the insight needed to recognize declining driving skills. The Alzheimer's Association built this approach around a simple fact: a diagnosis rarely changes someone's confidence behind the wheel, even as it changes their ability to drive safely. If conversation alone doesn't work, a formal on-road evaluation, written medical orders, lined-up transportation, and — eventually — physically removing access to the car form a sequence. Each step exists because the one before it sometimes fails, and caregivers who skip ahead to taking the keys often trigger a fight they could have avoided.

Start the Conversation Before a Crisis Forces It
Pick a calm, private moment, and keep the tone non-confrontational rather than treating it as an ultimatum. The Alzheimer's Association recommends bringing in a respected third party — a doctor, attorney, or adult child — because a person with Alzheimer's often can't independently judge their own declining skills, and hearing the concern from someone outside the marriage can land differently than hearing it from a spouse (Alzheimer's Association). Grounding the conversation in specifics helps.
Point to new dents or scratches on the car, a time your spouse got lost on a familiar route, errands that are taking far longer than they used to, or a new traffic ticket — concrete evidence is harder to argue with than a general worry about safety, and the Alzheimer's Association lists these as the signs worth raising directly. If your spouse signed a driving contract earlier in the disease — an advance agreement that family members can tell them when to stop — bring it back out now. The Alzheimer's Association designed these contracts to give caregivers something to point to later, precisely because insight fades as the disease progresses and an in-the-moment argument is harder to win than one settled in advance.
When a Driving Evaluation Settles the Question
For a spouse in the early or mild stage who still insists they're fine, a formal on-road evaluation by an occupational therapist or driving specialist is the recommended next step. According to a caregiver fact sheet from Easterseals and the Family Caregiver Alliance, a failed evaluation means the person must stop driving immediately — it removes the question from the realm of opinion (Caregiver.org). That evaluation only applies at the early stage.
Once dementia reaches moderate or severe, caregiver guidance is unambiguous: the person should not drive at all, regardless of how any single test goes, because the disease causes ongoing and often rapid decline that one good test result can't capture. A test passed this month says nothing about next month. A doctor's spoken instruction often isn't enough on its own — some caregivers report their spouse simply doesn't retain or accept a verbal warning. One tip sheet from Alzheimer's Greater Los Angeles recommends asking the physician to write "do not drive" on an actual prescription pad, so you have a physical document to produce when the conversation repeats, as it often does with memory loss.
Why the Law Won't Necessarily Step In For You
Don't assume the state will force the issue. A 2024 study in JAMA Network Open, led by USC researchers, found that only four states — California, Delaware, Oregon, and Pennsylvania — legally require physicians to report a dementia diagnosis to the DMV, and only 14 states require the patient to report it themselves. In the rest, nothing automatically happens after a diagnosis.
The same study found a troubling side effect where mandatory reporting does exist: primary care doctors in those states underdiagnosed dementia 59% more often — 12.4% of cases versus 7.7% elsewhere — a gap researchers at USC Dornsife attribute to patients hiding symptoms to protect their license (USC Dornsife). That means a diagnosis, even where reporting is required, may lag behind reality. The responsibility for stopping your spouse from driving will likely fall on you, not a state agency, in most of the country.
Set Up Alternatives Before the Driving Stops
Have transportation in place before you have the final conversation. The Alzheimer's Association recommends arranging family or friends to drive, senior transportation services, taxis or rideshare accounts, and delivery for groceries, medications, and meals — all set up in advance, so your spouse isn't suddenly stranded the day driving ends.
This step matters because resistance to giving up the keys often isn't really about driving — it's about the independence a car represents. A spouse who already sees a working replacement for errands and appointments has less to lose by agreeing, and you have a concrete answer ready the moment they ask "how will I get anywhere?".
If They Won't Stop, Remove the Car
When conversation and a failed evaluation still don't end the driving, caregiver organizations describe taking the keys, disabling the vehicle, or selling the car outright as the final step. Both the Alzheimer's Association and Caregiver Solutions frame this as a last resort that should follow the earlier steps, not replace them — it works far better once your spouse has already heard the same message from a doctor, a driving specialist, and a trusted family member (Alzheimer's Association).
Disabling the car quietly — removing a battery cable or hiding keys rather than announcing the car is gone — sidesteps a confrontation your spouse may not remember having anyway. Selling the vehicle is more final and removes the temptation entirely, which matters if your spouse tends to act on an impulse to drive even after agreeing to stop.
Frequently Asked Questions
Will the DMV automatically revoke my spouse's license after an Alzheimer's diagnosis?
Usually not. Only four states require a doctor to report the diagnosis, and just 14 require patients to self-report, according to the 2024 JAMA Network Open study — in most states, nothing happens automatically.
My spouse passed a driving test years ago — does that still count?
No. Caregiver.org guidance treats moderate or severe dementia as disqualifying regardless of past test results, since the disease causes ongoing decline that an old evaluation can't reflect.
What if my spouse keeps trying to drive after I take the keys?
Selling the car removes the option entirely, which caregiver organizations recommend when disabling the vehicle or hiding keys hasn't stopped the attempts.
