What Is a D4 Medical Exam and Why Do You Need It?
If you’re a professional driver or applying for a Group 2 license, you must pass a D4 medical exam. This exam ensures that you meet the DVLA’s medical fitness standards to drive HGVs, buses, Ambulances, and other commercial vehicles. It covers your eyesight, general health, and any medical conditions that could affect your driving ability.
Many drivers are surprised to learn that NHS GPs usually do not provide this service, meaning you’ll need to book with a private provider. In this guide, we’ll cover everything you need to know about finding a provider, costs, and what to expect during your D4 medical.
Where Can You Get a D4 Medical Exam?
Unlike regular health check-ups, D4 medical exams are not covered by the NHS, so you’ll need to find a private clinic or a specialist medical provider. Here are your main options:
1. Private D4 Medical Clinics

Private clinics specialize in driver medicals and offer appointments at competitive prices. These clinics are often faster, more affordable, and more convenient than NHS options.
2. Driving Schools & Training Providers
Some HGV and PCV training providers partner with medical professionals to offer discounted D4 medical exams as part of their training packages. If you’re taking an HGV course, check if they provide medicals.
3. NHS GP (Rare Option)

While most NHS GPs don’t offer D4 medicals, some do as a private service. However, these are often expensive and have limited availability. If your GP does provide this service, expect to pay significantly more than at a private clinic.
How Much Does a D4 Medical Exam Cost?
The cost of a D4 medical exam can vary depending on the provider and location. Here’s a breakdown of typical prices:
- Private Clinics: £45 – £70 (fast and affordable)
- Driving Schools: £55 – £80 (may be bundled with training)
- NHS GPs: £120 – £180 (if available)
Ways to Save Money on Your D4 Medical:
- Look for discounts or promo codes – Some clinics offer discount codes for online bookings.
- Compare multiple providers – Prices can vary by location, so check different clinics nearby.
- Book in advance – Last-minute appointments may cost more.
What Happens During a D4 Medical Exam?
A D4 medical exam is straightforward and usually takes around 20-30 minutes. Here’s what to expect:
1. Eye Test

- Your eyesight will be tested to ensure you meet the DVLA’s minimum requirements.
- If you wear glasses or contact lenses, bring them with you.
- Some clinics require a separate optician test, while others include it in the medical exam.
2. General Health Check
- Your doctor will check for medical conditions that could affect your ability to drive.
- They may ask about:
- Heart conditions
- Diabetes
- Neurological disorders (e.g., epilepsy)
- Mental health conditions
3. Blood Pressure Test

- High blood pressure can be a red flag, so maintaining a healthy level is important.
- Some providers may check your urine for signs of diabetes or other health concerns.
4. Completing the D4 Form
- The doctor will fill out your D4 medical form based on your results.
- If you pass, you’ll receive your completed D4 form the same day.
- If further medical checks are needed, you may need to visit a specialist before approval.
How Often Do You Need a D4 Medical?
The frequency of D4 medical exams depends on your age and driving history:
- First Application: Required for all Group 2 provisional license applicants.
- Age 45+: Renewal every 5 years.
- Age 65+: Annual renewals required.
If you have certain medical conditions, the DVLA may request more frequent medicals.
What If You Fail the D4 Medical?
Failing a D4 medical doesn’t necessarily mean you can’t drive. If you don’t pass, here’s what to do:
- Understand the reason for failure: Your doctor will explain if a medical condition is the issue.
- Seek treatment: In some cases, managing blood pressure or diabetes can help you pass on a retest.
- Appeal or provide additional medical evidence: If you believe your result was incorrect, you can request a second opinion.
What to Bring to Your D4 Medical Exam
To ensure a smooth appointment, bring the following items:
- Photo ID: Passport or driving license.
- D4 Form: Download from the DVLA or collect one at the clinic.
- Glasses or Contact Lenses: If you need them for driving.
- Medical Records (if applicable): Any relevant documents related to ongoing medical conditions.
