Medical conditions and car insurance

Your driving ability is one of the many factors used by insurance companies to calculate how much risk you present. If your driving is impeded by a medical issue, that presents an additional risk for your insurance company to take into account. Learning how to navigate how your condition affects your car insurance could prevent unwelcome surprises when it comes to your coverage.


How do health issues affect eligibility for car insurance?

There is no straight line from diagnosis to loss of your insurance. Health becomes an insurance issue if and when your medical condition affects the status of your driver's license. Your doctor can notify the DMV that you are not fit to drive. Unless you dispute this assessment with an appeal or your doctor updates your status, your license can be suspended. Your auto insurance company can drop you from coverage due to your suspended license. Insurers can't judge whether your condition affects your driving; they must instead rely on your doctor’s judgment and the DMV's guidance.

How do health issues affect car insurance premiums?

Suppose you have a medical condition when you’re shopping for car insurance. In that case, the company may ask a few questions, mainly to understand whether the condition could affect your ability to drive safely. The Americans with Disabilities Act (ADA) protects drivers from being charged more just because they have a disability, but insurers can adjust rates based on actual driving risk.

For example, things like limited mobility or vision challenges may increase the chances of an accident, so insurers may price the policy a bit higher. It’s similar to how they look at age, driving history, or credit—they’re focused on overall risk, not the condition itself. In some cases, drivers with medical needs might choose (or need) extra coverage for accessibility equipment or vehicle modifications, which can also affect the premium. These add-ons may include things like:

Custom equipment coverage

Also known as adaptation or special modification to vehicle coverage, this add-on covers car modifications for accessibility like pedal extenders, wheelchair ramps, adjustable seats, and push-pull hand controls. You can only get this coverage if you already have comprehensive and collision coverage.

zebra shield
Mobility insurance

If your ride is out-of-service, this additional coverage accounts for any costs for a temporary mode of transportation.

zebra shield
Equipment insurance

This covers extra-auto equipment that should be insured. These include walking sticks, wheelchairs, oxygen tanks, etc.

What medical conditions should be disclosed to a car insurance company?

It’s best to be completely transparent with your insurance company when shopping for quotes. Anything that affects your mental, physical, or cognitive state should be disclosed. Not doing so can risk your insurance coverage. 

Even if your condition is temporary (for example, if you’re recovering from a stroke), you should abstain from driving until you get the go-ahead from your doctor. Here are some health conditions that could affect driving ability. 

  • Arthritis
  • Diabetes
  • Heart conditions
  • Sleep apnea
  • Vision issues like cataracts
  • Chronic mental health issues
  • Neurological conditions like epilepsy, Parkinson’s disease, dementia, or stroke

Final thoughts

Insurance companies cannot deny you coverage solely due to a health condition. As long as it’s “controlled” with treatment or medication and your driving capabilities are vouched for by medical professionals, insurers, and the DMV should clear you to drive. Keep in mind that in some states, insurance providers are allowed to void policies of customers with conditions (like epilepsy) that can be a serious driving liability if not controlled by treatment. With a condition like epilepsy (and depending on the state you reside in), you need to have been seizure-free for some period of time before your driving privileges are reinstated. This protects both the insured driver and any fellow drivers they encounter on the road from potential accidents, mitigating the risk that insurance companies are so keen to lower.

Car insurance and medical conditions FAQs:

The biggest factors affecting car insurance rates are your driving record, location, vehicle type, age, and credit or auto insurance score. Accidents, tickets, and high-risk areas typically increase premiums the most.
