How long is a D4 medical form valid for?

D4 Form Timeline Rules:

• Strictly valid for 4 months (approximately 120 days).
• The countdown begins on the exact date of the doctor’s signature.
• Forms cannot be post-dated by the clinician.
• Expired forms require you to pay for and pass a new medical.

Timing is crucial when processing your commercial driving licence. If you are applying for a provisional HGV licence or renewing your current one, you should aim to have your D4 medical completed relatively close to your application submission date. If the DVLA receives a D4 form that is older than 4 months, they will instantly reject the application for safety reasons, forcing you to undergo the process again.

At Midland Medical Group, we offer rapid appointments so you can get your form signed exactly when you are ready to send your complete application package to Swansea.
