When Is It Time for an Older Adult to Stop Driving?

There is no single age at which an older adult should stop driving. The question is whether health changes, such as memory loss, vision problems, slowed reactions or medication effects, are making driving unsafe. Warning signs include new dents, getting lost on familiar roads, near misses and confusion at intersections. A driving evaluation by a clinician or driving rehabilitation specialist can help decide. This article covers the signs, the health causes, how to talk about it, and alternatives.

When is it time for an older adult to stop driving?

Age alone does not decide it. Many older adults drive safely for years, and others develop problems earlier. What matters is how a person's thinking, vision, physical movement and medicines affect their driving today. The question is best answered by looking at specific changes and, when worry persists, by arranging a formal evaluation.

MedlinePlus, the National Library of Medicine's patient site, lists motor vehicle safety as a topic that includes older drivers, and it is a reasonable starting point for general safety information: Motor Vehicle Safety.

Warning signs you can notice from the passenger seat

Family members often see changes before the driver does. Common warning signs include:

• New dents, scrapes or scratches on the car, the garage or the mailbox
• Getting lost on routes the person has driven for years
• Drifting between lanes, braking suddenly or driving much slower than traffic without a reason
• Missing stop signs, traffic lights or pedestrians
• Confusion at intersections, on highway ramps or when making left turns
• Near misses, or other drivers honking more often
• Traffic tickets or warnings that are new
• Feeling anxious, overwhelmed or exhausted after driving
• Friends or family who have stopped riding with them

One incident does not settle the question. A pattern over weeks or months deserves attention.

Health conditions that can affect driving

Memory and thinking changes

Dementia can affect judgment, attention, planning and the ability to react to the unexpected. A review in the medical literature, Driving and dementia: a review of the literature, discusses how driving ability can change as dementia progresses and why assessment matters. Getting lost on familiar roads is often a concern. Our article on early signs of dementia versus normal aging explains how to tell ordinary forgetfulness from something more. MedlinePlus also has a general page on Dementia.

Not everyone with a diagnosis of dementia has to stop driving the day they are diagnosed. Ability varies, and it tends to decline over time, so repeated checks are usually better than a single decision.

Vision changes

Driving relies heavily on vision, including sharpness, side vision, contrast and glare sensitivity. Research on the topic is summarized in Visual factors in automobile driving. Conditions such as cataracts, glaucoma and macular degeneration can reduce these abilities, sometimes gradually enough that the person adapts without noticing. Night driving is often the first thing to become difficult. See our article on early signs and risk factors of age-related macular degeneration for more. An eye care professional can check whether vision meets the standard needed for driving.

Hearing loss

Hearing loss can make it harder to notice sirens, horns or a problem with the car. We cover causes in our article on why hearing loss increases in older age. Hearing aids may help, and a clinician can advise.

Slower movement and reaction

Arthritis, stiffness, weakness, neuropathy and the effects of a stroke can make it harder to turn the head, steer, or move a foot between pedals. Some people can adapt with vehicle modifications. Others find that physical limits make driving unsafe.

Distraction and divided attention

Older drivers may find it harder to do two things at once. A study titled Distracted driving in elderly and middle-aged drivers examines how distraction affects drivers of different ages. Phone use, a busy passenger or complicated navigation prompts can all add load.

Sleep problems

Drowsiness can impair driving at any age. Sleep disorders, such as sleep apnea, can cause daytime sleepiness. MedlinePlus lists common types on its Sleep Disorders page. A person who nods off, or nearly does, at the wheel should talk with a clinician.

Medicines and alcohol

Many prescription and over-the-counter drugs can cause drowsiness, dizziness, blurred vision or slowed thinking. These include some sleep aids, anxiety medicines, opioid pain medicines, certain antidepressants, some antihistamines and some medicines for bladder control. Older adults often take several medicines, and combined effects may be harder to predict. Research on this topic includes Evaluating and Determining the Effects of Psychotropic Drugs on Motor Vehicle Driving Performance, which describes how drug effects on driving can be assessed.

Check the label and ask the prescriber or pharmacist whether a medicine can affect driving. Do not change the dose or timing of a prescribed medicine on your own; talk with the prescriber first. A medication review with a pharmacist or physician is a practical step. Alcohol can add to these effects, and MedlinePlus has information on Alcohol Use Disorder.

How to get an objective picture

If you are unsure, an outside assessment can take the pressure off the family. Options include:

• A visit with the primary care clinician. Bring a list of specific observations, and a list of all medicines, including over-the-counter ones and supplements. The clinician can check vision, memory, strength, balance and medication effects.
• An eye exam. Vision problems can be treatable.
• A driving evaluation. Occupational therapists with driving rehabilitation training often perform on-road and off-road assessments. They may also recommend adaptive equipment or lessons.
• The state motor vehicle agency. Rules differ by state. Some states allow family members or clinicians to request a review of a driver's fitness. Check your own state's rules.

Ask your clinician what they recommend for your situation, since the right approach depends on the person's conditions.

Having the conversation

For many people, driving stands for independence, so the topic can feel threatening. Some approaches that may help:

• Start early and often. Raising the subject before a crisis, as part of planning, tends to go better than a confrontation after an accident.
• Choose a calm time and a private place. Avoid talking in front of a large group.
• Use specific observations. "I noticed the car has new dents" is easier to hear than "you are a bad driver."
• Listen first. Ask what worries them and what they would miss most.
• Involve someone they trust. A doctor, a religious leader or a longtime friend may be better received than a child.
• Offer a plan, not just a restriction. People accept change more easily when they can see how they will still get to appointments, shops and friends.

Caregivers of people with memory loss can find more support in MedlinePlus's Alzheimer's Caregivers page. Caregiving is stressful, and MedlinePlus has general information on Stress.

If the person refuses and there is clear danger, involve the clinician. Some families also take the keys or disable the car as a last step, though this is a hard decision best made with professional guidance.

Steps short of stopping completely

Some older adults can reduce risk rather than quit. Possible steps include:

• Avoiding night driving, rush hour, bad weather and highways
• Sticking to familiar routes close to home
• Keeping the windshield and headlights clean, and using larger mirrors or other vehicle aids
• Getting regular eye and hearing checks
• Keeping physically active to maintain strength and flexibility
• Putting the phone away while driving

Limits like these can be a bridge, but if problems keep appearing, a fuller evaluation is reasonable.

Staying connected after driving ends

Giving up driving can lead to isolation, sadness and a sense of lost control. Planning ahead may soften the change. Options include:

• Rides from family, friends or neighbors on a schedule
• Public transit and paratransit services
• Senior center, faith-based or volunteer driver programs
• Taxis and ride-share services, with a family member helping set up the app
• Grocery and pharmacy delivery, and telehealth visits where appropriate

Your local Area Agency on Aging can often point you to programs. For other health topics that matter at this stage, see MedlinePlus's Older Adult Health page. If the person is feeling persistently low or hopeless after losing the car, tell their clinician, and if they mention thoughts of self-harm, call or text the 988 Suicide and Crisis Lifeline.

After a crash or a medical event

A fall, stroke, seizure, fainting spell, heart event or hospital stay can change fitness to drive abruptly. A person should ask the treating clinician when driving is safe again. The same applies after a new medicine or a change in dose. A crash with no obvious cause, or one the person cannot remember, warrants prompt medical attention.
