A medical diagnosis does not automatically mean that you must stop driving permanently. However, some health conditions, disabilities and treatments can affect your ability to drive safely and must be reported to the Driver and Vehicle Licensing Agency (DVLA).
The rules apply to provisional as well as full driving licences. That means learner drivers must give accurate medical information when applying for a licence and report relevant changes that happen later.
Whether you need to notify the DVLA depends on the condition, its severity, your symptoms, your treatment and the type of vehicle you drive. You should therefore check the official rules for your specific circumstances rather than relying on a general list.
This article covers licences issued in Great Britain. Drivers in Northern Ireland should contact the Driver and Vehicle Agency (DVA), as it handles licensing there.
What is a notifiable medical condition?
A notifiable condition is a health issue or disability that could affect your ability to drive safely. You have a legal responsibility to tell the DVLA if a condition is notifiable or if an existing condition becomes worse in a way that may affect your driving.
The DVLA provides an online service called Check if a health condition affects your driving on GOV.UK. It explains whether a particular condition must be reported and how to do so.
Do not assume that the DVLA will automatically receive all the necessary information from your GP, consultant or hospital. The responsibility to make the notification normally rests with the licence holder or applicant.
You must also answer medical questions on a provisional or full licence application truthfully. Leaving out relevant information could put you and other road users at risk.
Medical issues that may need to be disclosed
There is no simple rule saying that every diagnosis in a particular category must always be reported. The requirements frequently depend on symptoms, treatment and licence type. Nevertheless, the following are important areas to check.
Epilepsy, seizures and unexplained blackouts
Epileptic seizures, fits, loss of consciousness and unexplained blackouts can affect control of a vehicle without warning. These events may need to be reported even if they happened away from the road or while you were asleep.
The rules take account of factors such as the type of seizure, when it occurred and whether it was an isolated event. Do not try to calculate your own seizure-free period from unofficial advice. Check the current DVLA guidance and discuss the situation with your doctor.
Strokes and neurological conditions
A stroke or transient ischaemic attack, often called a TIA or mini-stroke, can affect vision, movement, concentration and reaction times. Whether and when you can drive again depends on the event, your recovery and the type of licence you hold.
Other neurological conditions that may require notification include multiple sclerosis, Parkinson’s disease, dementia, narcolepsy and certain brain injuries or tumours. Progressive symptoms are particularly important because driving ability can change over time.
Diabetes and hypoglycaemia
Diabetes does not automatically prevent someone from driving. The reporting rules depend on how it is treated, whether the driver experiences severe hypoglycaemia and whether they can recognise warning signs of low blood sugar.
Some insulin-treated drivers and people who experience certain episodes of hypoglycaemia must notify the DVLA. Different requirements apply to bus and lorry licences. Follow medical advice about glucose monitoring, meals and treatment, and never begin a journey if your blood glucose or symptoms make driving unsafe.
Heart and circulatory conditions
Some heart conditions can cause dizziness, fainting, breathlessness or sudden incapacity. Conditions and procedures that may need checking include serious heart rhythm problems, implanted defibrillators, heart attacks and some types of heart surgery.
The requirement to report and any period away from driving depend on the diagnosis, treatment and licence category. A clinician can advise whether you should stop driving immediately, but you should still use the official DVLA condition checker to establish your notification duties.
Eyesight problems
Drivers must meet the legal eyesight standards whenever they drive, not only on the day of a practical test. Problems involving visual acuity, visual fields or double vision may be notifiable.
If your eyesight changes suddenly, stop driving until you have received appropriate advice. Glasses or contact lenses must be worn while driving if they are needed to meet the required standard. Passing a number plate check does not remove the obligation to report a separate notifiable eye condition.
Sleep disorders and excessive sleepiness
Obstructive sleep apnoea and other sleep disorders can produce excessive daytime sleepiness, slow reactions and brief episodes of sleep. The diagnosis alone is not the only consideration; the degree of sleepiness and its effect on safe driving are crucial.
You must not drive when excessively sleepy. Seek medical help promptly and check whether the condition must be reported. Treatment can often control symptoms, but you should wait for professional advice before returning to the road.
Fatigue can also affect people without a diagnosed sleep disorder. When you are medically fit to drive, sensible route planning and rest breaks remain essential, particularly on longer journeys. Our holiday road trip safety tips explain how to prepare for extended travel.
Mental health conditions
A mental health diagnosis does not necessarily have to be reported. Notification can depend on the severity of symptoms and whether they affect judgement, concentration, behaviour or the ability to drive safely.
Conditions such as severe depression, bipolar disorder, psychosis and schizophrenia may be notifiable in particular circumstances. The effects of prescribed medicine must also be considered. Ask the clinician treating you and check the condition-specific DVLA guidance rather than stopping medication without advice.
Alcohol or drug misuse and dependence
Alcohol dependence, persistent misuse of alcohol, and misuse or dependence involving drugs can result in medical licensing action. This is separate from the criminal offences of drink-driving and drug-driving.
Prescription and over-the-counter medicines can also cause drowsiness, blurred vision or slower reactions. Read the patient information leaflet and follow advice from your doctor or pharmacist. A medicine being legally prescribed does not make it safe to drive while impaired.
Physical disabilities and loss of limb function
A new disability, loss of limb function or significant restriction in movement may affect steering, braking and other vehicle controls. The DVLA may need medical information or evidence that you can drive safely with suitable adaptations.
Adaptations can help many people continue driving. Depending on the circumstances, the licence may record restrictions requiring the use of particular controls or vehicle features.
Group 1 and Group 2 medical standards
The medical standards are divided broadly into two groups:
- Group 1 covers cars and motorcycles.
- Group 2 covers lorries and buses.
Group 2 standards are generally stricter because the vehicles are larger, journeys may be longer and professional drivers can spend more time on the road. A condition that does not require action for a car licence may still need to be reported for a bus or lorry entitlement.
Most learner drivers are applying for a Group 1 provisional licence, but it is important to select the correct licence category when reading medical guidance.
How to tell the DVLA about a condition
Start by searching for your condition using the official GOV.UK medical condition checker. It will tell you whether to report it and whether you can use an online service or need to complete a medical questionnaire.
You may be asked for details including:
- your diagnosis and symptoms;
- dates of treatment or medical events;
- medicines you take;
- contact details for your GP or consultant;
- information about blackouts, seizures or other episodes; and
- consent for the DVLA to approach healthcare professionals.
Provide complete and accurate information. Missing details can delay the decision because the DVLA may need to contact you again.
If you are unsure whether you can drive while the DVLA considers your case, obtain specific advice. In limited circumstances, Section 88 of the Road Traffic Act 1988 may allow someone to drive while a valid application is being processed, but several conditions must be met. It does not apply to everyone, and it does not override medical advice not to drive.
What can the DVLA decide?
After considering the information, the DVLA may:
- allow you to keep or receive a licence without additional restrictions;
- issue a licence for a shorter period, followed by a medical review;
- require vehicle adaptations or licence restrictions;
- ask you to take a driving assessment, eyesight test or driving appraisal; or
- refuse or revoke the licence if the medical standards are not met.
A short-period licence does not necessarily mean that your condition makes you unsafe. It allows the DVLA to review whether you continue to meet the required standard.
You may also choose to surrender a licence on medical grounds in appropriate circumstances and reapply when your health improves. Discuss this with your doctor and follow the DVLA process rather than simply letting the licence expire.
What happens if you do not report a condition?
You can be fined up to £1,000 for failing to tell the DVLA about a medical condition that affects your driving. You may also be prosecuted if you are involved in a collision as a result of the condition.
There can be insurance consequences as well. Telling the DVLA does not necessarily fulfil your obligations to your insurer. Check your policy and notify the insurer where required, especially if your licence changes or vehicle adaptations are introduced.
Most importantly, do not drive if a doctor has advised you to stop or if symptoms make you unsafe. A valid photocard is not proof that you are medically fit at every moment.
Practical steps for learner drivers
If you develop a relevant condition while learning, pause lessons and contact your instructor. Your instructor cannot decide whether you meet the DVLA medical standards, but they need to know if lessons must stop or an adapted vehicle may be required.
Take these practical steps:
- Follow immediate medical advice, including any instruction not to drive.
- Check your condition on GOV.UK.
- Notify the DVLA promptly if required.
- Keep copies of forms and relevant correspondence.
- Tell your instructor when the DVLA confirms that you can continue learning.
- Check whether your insurance or lesson provider needs additional information.
Once you are cleared to drive, remember that illness and medication can combine with difficult conditions to increase risk. The advice in our guide to safer festive winter driving can help with planning around darkness, ice and severe weather.
Frequently asked questions
Do I have to report every medical diagnosis to the DVLA?
No. Only conditions covered by the notification rules need to be reported. However, the details matter: symptoms, treatment and licence category can change the answer. Check your exact condition using the official GOV.UK service.
Does my doctor tell the DVLA for me?
You should not assume so. It is normally your responsibility to notify the DVLA. In exceptional circumstances, a doctor may disclose relevant information in the public interest if a patient continues driving against advice, but this does not remove your own legal duty.
Can I take driving lessons while waiting for a DVLA medical decision?
Possibly, but only if you are legally entitled and medically fit to drive. The rules about driving while an application is being considered are specific and Section 88 does not apply in every case. Ask the DVLA and your healthcare professional if you are uncertain.
Will reporting a condition mean losing my licence?
Not necessarily. The DVLA may allow you to drive normally, issue a short-period licence, or require adaptations or further assessment. Refusal or revocation is generally considered where the required medical standards are not met.
Conclusion
Learner and qualified drivers have a responsibility to report notifiable medical conditions to the DVLA. Because the rules vary by diagnosis, symptoms, treatment and licence type, always use the official condition checker and follow advice from a qualified healthcare professional.
Reporting a condition does not automatically end your driving plans. Prompt, honest disclosure allows the DVLA to assess your fitness properly and decide whether you can drive safely, with restrictions or adaptations where necessary.
