Driving with a medical condition: what to tell the DVLA

The law requires you to tell the DVLA about certain "notifiable" medical conditions that could affect your driving. Failing to do so can mean a fine of up to £1,000 and prosecution if you have an accident. The DVLA, not you, decides whether you are fit to keep your licence, often after seeking medical advice.

Do you have to tell the DVLA about a medical condition?

You must tell the DVLA about any notifiable medical condition or disability that could affect your ability to drive safely. This is a legal duty that sits with you, the licence holder, not with your doctor.

It applies both to conditions you already have when you apply for a licence and to conditions that develop or worsen later. If you are ever unsure whether something is notifiable, the safe step is to check the official list on GOV.UK or ask the DVLA directly rather than assume it does not count.

Which medical conditions must be declared?

The list is long and covers conditions affecting consciousness, vision, mobility, the heart, and the brain. Common examples include epilepsy and other conditions causing blackouts, diabetes managed with insulin, certain heart conditions, strokes, sleep conditions such as sleep apnoea, and some eyesight conditions.

Each condition has its own specific rules and thresholds, and they change, so this page deliberately does not state them. Check the GOV.UK guidance for your particular condition, and follow the advice of your doctor about whether and when it is safe to drive.

What happens if you drive without declaring a condition?

Failing to tell the DVLA about a notifiable condition is an offence that can bring a fine of up to £1,000. If you are involved in an accident as a result of a condition you failed to declare, you can be prosecuted more seriously.

There is also an insurance consequence, covered below, that can leave you personally liable for a claim. Declaring a condition does not automatically mean losing your licence, so there is rarely anything to gain and a great deal to lose by staying quiet.

How do medical conditions affect car insurance?

If the DVLA requires you to declare a condition, your insurer generally needs to know as well. Insurance is based on an accurate picture of risk, and failing to disclose a relevant medical condition can allow the insurer to refuse a claim or void the policy entirely.

A declared condition does not always increase your premium, and many drivers see no change at all once the DVLA is satisfied they are fit to drive. The danger lies in non-disclosure, not in being honest about a managed condition.

What is a DVLA medical questionnaire?

When you report a condition, the DVLA may send you a questionnaire about it and ask for permission to contact your doctor or specialist. In some cases they arrange a medical examination or a driving assessment.

This is a routine part of the process, not a sign that your licence is at risk. The DVLA uses the information to decide whether you meet the medical standards for driving, and they make that decision, drawing on medical evidence, rather than leaving it to you to judge.

Can you lose your licence for a medical condition?

Yes, in some cases. If the DVLA decides you do not currently meet the medical standards, it can revoke or refuse your licence. Often, though, the outcome is less drastic: the DVLA may issue a licence for a shorter period, such as one, two, three or five years, subject to review.

If your licence is revoked, you can usually reapply once your condition is stable or treated and you again meet the standards. You also have the right to appeal a decision you believe is wrong.

What about temporary conditions and medication?

Not everything needs declaring. Short-term conditions that pass quickly, such as a bout of flu or a broken arm that heals normally, do not usually need to be reported, though you must not drive while a temporary problem actually affects your ability to do so safely.

Medication is a separate consideration. Some prescription medicines, including certain strong painkillers and sedatives, can impair driving and even bring you within the scope of drug driving law. If a medicine you take could affect your driving, follow the advice of your doctor or pharmacist, and do not drive if you feel drowsy or slowed by it. The clear distinction the DVLA draws is between a notifiable long-term condition, which you must report, and a passing illness, which simply means not driving until you have recovered.

How to inform the DVLA about a medical condition

You report most conditions to the DVLA online or by post, using the specific form for your condition, which you can find through GOV.UK. There are separate processes for car and motorcycle licences and for bus, coach and lorry licences, which have stricter standards.

Do not stop driving simply because you have reported a condition, unless your doctor tells you to or the rules for that condition require it. The key actions are to report promptly, follow medical advice, and tell your insurer where the condition is one the DVLA needs to know about. Keep a note of when you reported it and any reference number, in case you need to show you met your legal duty.

Frequently asked questions

Which medical conditions must be reported to the DVLA?

Conditions that could affect safe driving, including epilepsy and blackouts, insulin-treated diabetes, certain heart conditions, strokes, sleep apnoea and some eyesight conditions. Each has its own rules, so check the GOV.UK list for your condition rather than relying on a general summary.

Do I need to tell my insurer about a medical condition as well as the DVLA?

Generally yes. If the DVLA requires you to declare a condition, your insurer usually needs to know too. Non-disclosure can let the insurer refuse a claim or void the policy. Being honest about a managed condition often has no effect on the premium.

What happens if I drive without declaring a condition and have an accident?

Failing to declare a notifiable condition can bring a fine of up to £1,000, and causing an accident as a result can lead to more serious prosecution. Your insurance may also be void, leaving you personally liable for the costs of a claim.

Can a GP report your medical condition to the DVLA without telling you?

A doctor will normally encourage you to report it yourself first. If you continue to drive against medical advice and pose a risk, a doctor can, as a last resort, inform the DVLA. The primary legal duty to report, however, rests with you.

Can I appeal if the DVLA revokes my licence on medical grounds?

Yes. You have the right to appeal a DVLA decision you believe is wrong. You can also usually reapply for your licence once your condition is treated or stable and you again meet the medical standards for driving.
