D4 Medical

Step-by-Step Roadmap to a Successful D4 Medical Appointment

If you’re applying for or renewing a Group 2 driving licence for HGVs, buses, or taxis, a D4 medical examination is a legal requirement. At SimplyMedicals, we make the process straightforward and stress-free. In this blog, we’ll walk you through the key steps you need to take to prepare for and complete your D4 medical successfully.

What Is a D4 Medical and Who Needs One?

The D4 medical is an official health check required by the DVLA for drivers of vehicles over 3.5 tonnes or for passenger-carrying vehicles (PCVs). So, to drive a lorry or an ambulance etc, it is necessary. It’s commonly needed for:

  • HGV/LGV drivers (Category C, C1, C+E)
  • Bus or coach drivers (Category D, D1, D+E)
  • Taxi drivers (depending on local council requirements)

You’ll need to complete a D4 form, which includes both a vision assessment and a general medical examination. It ensures that you are fit to drive safely and meet DVLA standards.

You’ll usually need a D4 medical:

  • When applying for your first Group 2 licence
  • Every 5 years once you turn 45
  • Annually after age 65

How to Prepare for Your D4 Medical Appointment

To make your D4 medical appointment smooth and successful, follow these preparation tips:

  1. Bring the Right Documents:
    • A completed D4 form (if you have it)
    • Valid photo ID (passport or driving licence)
    • Your current prescription or glasses/contact lenses, if you wear them
    • A list of any medications you’re taking
    • Any relevant hospital letters or medical history (especially for conditions like diabetes, sleep apnoea, or heart issues)
  2. Know Your Medical History:
    Be ready to discuss your health history, including any surgeries, mental health conditions, vision or hearing problems, and ongoing treatments.
  3. Be Honest and Accurate:
    The doctor needs accurate information to complete the D4 form. Providing clear answers will avoid delays or rejections from the DVLA.

What to Expect During and After the Appointment

At SimplyMedicals, our appointments are quick, professional, and DVLA-compliant. Here’s how it works:

  • Vision Test: Your eyesight will be tested to DVLA standards, with or without corrective lenses.
  • Medical Exam: The doctor will check your blood pressure, assess your medical history, and complete the D4 form accordingly.
  • Form Completion: We’ll fill out your D4 form accurately and hand it over to you for submission—or submit it electronically if your local authority allows.
