If your loved one has dementia, deciding when they can no longer drive is a difficult decision. They may react in different ways:
They may be aware they are having problems, and they may be relieved to stop driving.
They may feel their independence is being taken away.
Signs that Driving May No Longer Be Safe
People with signs of dementia should have regular driving tests. Even if they pass a driving test, they should be retested in 6 months.
If your loved one resists you getting involved in their driving, get help from their health care provider, lawyer, or other family members.
Even before you see driving problems in someone with dementia, look for these signs that they may be at risk for driving badly:
Forgetting recent events
Mood swings or getting angry more easily
Problems doing more than one task at a time
Problems judging distance
Having trouble making decisions and solving problems
Becoming confused more easily
Signs that driving may be getting more dangerous are:
Getting lost on familiar roads
Reacting more slowly in traffic
Driving too slowly or stopping for no reason
Not noticing traffic signs or not paying attention to them
Taking chances on the road
Drifting into other lanes
Getting more agitated in traffic
Getting scrapes or dents on the car
Having trouble parking
Steps to Take
It may help to set limits when driving problems start. Stay off busy roads, or do not drive at times of the day when traffic is heaviest.
Do not drive when the weather is bad. Do not drive long distances. Drive only on roads the patient is used to.
Caregivers should try to lessen the person’s need to drive without making them feel isolated. Have someone deliver groceries, meals, or prescriptions to their home. Find a barber or hairdresser who will make home visits. Arrange for family and friends to visit and take them out for a few hours at a time.
Plan other ways to get your loved one places. Family members or friends, buses, taxis, and senior transportation services may be possibilities.
As danger to others or to your loved one increases, you may need to prevent to them from being able to use the car. Some ways to do this are:
Hiding the keys
Leaving out car keys that will not start the car
Disabling the car so it will not start
Selling the car
Storing the care away from the home
