How to Prepare for Your D4 Medical and Taxi Medical in the UK: Tips from Certified Doctors
Why Preparation Matters for Your D4 or Taxi Medical
Whether you’re applying for an HGV/PCV licence or getting licensed as a taxi or private hire driver, your medical exam plays a vital role in the approval process. The D4 medical and various council taxi medicals follow strict DVLA Group 2 standards, ensuring that all drivers are medically fit for professional road use.
A well-prepared appointment reduces the risk of delays, additional documentation, or even rejection.
Who Needs These Medicals?
- HGV & PCV drivers: Required to take a D4 medical when applying or renewing their Group 2 licence
- Taxi & private hire drivers: Must take a medical based on council requirements—often using DVLA Group 2 standards
- Drivers over 45: Medical required every 5 years
- Drivers over 65: Medical required annually

If you have any of these, please bring a letter from your GP or specialist showing that the condition is well-controlled and doesn’t affect your driving.

Your eyesight must meet the DVLA’s Group 2 driving standard.
What to prepare:

- Please’ before bring your latest eye prescription
- Make sure your vision meets the standard on a Snellen chart (6/7.5 or better)
