Frequently Asked Questions (FAQs) about the DVLA D4 Medical Form
How long does a D4 medical take?
A D4 medical examination usually takes 20–30 minutes, depending on your medical history. The doctor will check your vision, blood pressure, and overall health, and complete the D4 form on your behalf. If additional tests are needed (e.g., diabetes checks, specialist letters), it may take longer.
Can I use my NHS GP for the D4 medical?
Yes, you can ask your NHS GP to complete the D4 medical form. However, many NHS practices do not offer this service, or they may charge a higher fee (£100–£150). Most drivers choose a private medical clinic for quicker, affordable appointments (usually £50–£90).
How long is the D4 form valid for?
Once completed, the D4 form is valid for 4 months from the date of the medical examination. If you don’t submit it to DVLA within this timeframe, you may need to book and pay for another medical.
