Driver medicals explained: what's checked and how to prepare
If your licence is up for renewal and a medical is on the list, it is natural to feel a little unsure. What will the doctor check? What do you need to bring? What happens if something is flagged?
A driver medical is usually quick and straightforward, especially if you are prepared. This guide explains who needs one, what the examination covers and how to avoid the delays that catch people out.
Who needs a driver medical?
It depends on what you drive.
Lorry, bus and coach drivers. If you hold, or want, a Group 2 licence (the category covering large lorries and buses), you need a medical examination report, known as a D4. The DVLA’s D4 guidance notes set out when it is required. In short:
- When you first apply for a lorry or bus licence
- When you renew at age 45
- Every five years after that until you are 65
- Every year from the age of 65
Taxi and private hire drivers. Most councils require a medical to a Group 2 standard when you apply for a licence and when you renew. How often varies by council, so check your local authority’s rules. Our taxi driver medicals are carried out to DVLA Group 2 standards, in line with council requirements.
Forklift and other workplace drivers. There is no DVLA form for forklift operators. But employers often ask for a medical before you start work and at intervals after that, to confirm you are fit for the role. We offer forklift driver medicals for this.
Car drivers. Most people with a standard car licence never need a medical. You do, however, have a legal duty to tell the DVLA about any medical condition that could affect your driving. A doctor can help you work out what to report.
Why the standards are higher for large vehicles
Driving a lorry, bus or taxi means long hours, large vehicles and the safety of other people. The DVLA sets higher medical standards for Group 2 than for ordinary car driving. That is why the examination is more detailed.
It is not designed to catch you out. Plenty of drivers with long-term conditions such as diabetes or high blood pressure keep their licences, as long as their condition is well controlled and they meet the standards.
What does the doctor check?
The D4 is a structured form, and the doctor works through it with you. Expect the examination to cover:
Your medical history. The doctor goes through your past and current conditions, operations, hospital visits and medicines. This is why a GP summary matters.
Your vision. Your eyesight is tested with the glasses or contact lenses you wear for driving. If you need them, you must bring them, along with your prescription.
Your blood pressure and general health. The doctor takes your blood pressure, checks your pulse and does a general physical examination.
Specific conditions. The D4 asks about areas that can affect safe driving, including:
- Heart conditions, such as a past heart attack, angina or irregular heartbeat
- Diabetes, particularly if you use insulin
- Neurological conditions, including epilepsy, stroke and blackouts
- Mental health conditions
- Sleep problems, including sleep apnoea and excessive tiredness
- Alcohol or drug misuse
- Medicines that could cause drowsiness
Having one of these on your record does not mean you will be refused. The DVLA looks at the type of condition, how well controlled it is and what it means for safe driving.
How to prepare for your driver medical
A little preparation saves a lot of time. Here is what to bring.
Your D4 form. The DVLA usually sends this out before your renewal date. You can also download the D4 form from GOV.UK. Fill in the sections meant for you, in front of the doctor.
A full GP summary. This is a record of your medical history. You can get it free from your GP or through the NHS App. For bus and taxi medicals, it is essential. If you have trouble getting hold of it, tell us and we will guide you.
Your glasses or contact lenses, and your prescription. The eyesight test must use what you actually wear for driving. Bring a recent prescription from your optician, if you have one.
Your current medicines. A repeat prescription slip is ideal.
Relevant test results or letters. For example, from a hospital clinic or diabetes review.
Photo ID. A passport or driving licence.
A few more tips:
- Do not book too early. A completed D4 is valid for four months. If you have your medical too soon, it may expire before you apply.
- Do not leave it to the last minute. If the doctor needs more information from your GP or a specialist, it can take time to arrive.
- Check your own health first. If you know your blood pressure has been high, or you are unsure about a condition, talk to a doctor before the medical.
What happens at the appointment?
The appointment usually takes around 20 minutes.
- Check-in and ID. We confirm who you are and look at your form.
- Medical history. The doctor goes through your history and medicines, using your GP summary.
- Vision test. We check your eyesight with your glasses or lenses.
- Examination. We take your blood pressure, check your pulse and carry out a general examination.
- Completing the form. The doctor fills in their sections, signs and stamps the report, and talks through anything that needs follow-up.
You then send the completed D4 to the DVLA with your application form and driving licence. Check that every section is complete first, because the DVLA can send back an incomplete report.
What if something is flagged?
This is the worry most people have. Here is the reality.
A flagged condition does not automatically mean you fail. The doctor reports what they find, and the DVLA makes the licensing decision. They may ask for more information, such as a letter from a specialist, or may issue a licence for a shorter period.
If you already know about a condition that might be an issue, tell your doctor honestly. Hiding it can cause bigger problems later, and it is against the rules. If you are worried, book a private GP appointment before your medical. We can review your health, check things like your blood pressure and work out what documentation you will need.

Frequently questions our patients ask
Who needs a D4 medical?
Anyone applying for or renewing a lorry or bus (Group 2) licence needs a D4 medical report at their first application, at 45, every five years until 65, and every year from 65. Many councils also ask taxi and private hire drivers for a medical to the same standard.
How long does a driver medical take?
Usually around 20 minutes. It may take a little longer if the doctor needs to go through a more complex medical history.
How long is a D4 medical valid for?
A completed D4 is valid for four months from the date of the examination. Send it to the DVLA within that time, or the medical may need repeating.
What do I need to bring to a driver medical?
Bring your D4 form, a full GP summary, your glasses or contact lenses and prescription, your current medicines, any relevant test results and photo ID.
Can I still drive if I have diabetes or high blood pressure?
Often, yes. Many professional drivers have these conditions. The DVLA looks at how well controlled they are and whether you meet the standards. A doctor can advise on what applies to you.
