If you’re a professional driver in the UK—whether for HGV, PCV, or taxi work—you’re likely familiar with the D4 medical form. This essential check-up ensures you’re fit to drive and helps keep both drivers and the public safe. At SimplyMedicals, we conduct hundreds of D4 medicals each year, and we often see the same questions and avoidable issues crop up. Staying prepared can save you time, money, and stress.
In this post, we’ll walk you through how to prepare for your annual or renewal D4 medical check-up, what to expect during your appointment, and how to avoid common delays.
Understand What the D4 Medical Covers
The D4 medical form assesses whether you’re medically fit to drive a large or passenger-carrying vehicle. It includes questions about your vision, cardiovascular health, mental health, diabetes, neurological conditions, sleep disorders, and alcohol or drug use.
Tip: You don’t need to be in perfect health, but you do need to meet the DVLA’s medical standards. If you have a condition that could affect your ability to drive safely, it’s important to bring documentation, prescriptions, or recent specialist letters with you.
Your D4 medical is usually required:
- When first applying for a Group 2 licence (HGV/PCV)
- Every 5 years from age 45–65
- Annually after age 65
- By some councils for taxi and private hire drivers
Bring the Right Documentation
To avoid rescheduling or delays, make sure you come to your appointment with the correct paperwork. You’ll need:
- A form of photo ID (driver’s licence or passport)
- Glasses or contact lenses, if you wear them
- A list of any current medications
- Details of any hospital stays, diagnoses, or surgeries
- Your most recent prescription or optician’s report (optional but helpful)
Tip: If you wear glasses or lenses, your eyesight will be checked. Make sure your prescription is up to date. If your vision falls below DVLA standards, your form can’t be signed off.
Plan Ahead—Don’t Leave It Last Minute
Many drivers leave their D4 medical to the last minute, which can lead to missed licence renewal deadlines, fines, or even being temporarily unable to work. At SimplyMedicals, we offer flexible appointment slots, often with same-day availability, but it’s always better to plan ahead.
Tip: Book your D4 medical at least a month before your licence is due for renewal. This gives you enough time for follow-ups if additional information or specialist input is needed.
