Everything professional drivers need to know about the DVLA Group 2 driving medical — explained clearly by Dr. Zain Abideen.
A D4 medical examination is the official DVLA medical assessment required for Group 2 driving licences. Group 2 covers large lorries (HGV/Category C) and buses and coaches (PCV/Category D), as well as taxis in many areas.
The examination must be carried out by a GMC-registered doctor and recorded on the official D4 form. This form is then submitted to the DVLA as part of your licence application or renewal.
The examination typically takes 15–20 minutes and covers vision, blood pressure, BMI, and a thorough review of your medical history.
The DVLA requires a D4 at specific points in your driving career.
When applying for your first provisional HGV or PCV licence. A D4 submitted within the last 12 months is accepted.
The first age-related medical is required when renewing your Group 2 entitlement at age 45.
Between the ages of 45 and 65, a D4 is required every five years at each licence renewal.
From age 65 onwards, a D4 medical is required every single year to maintain your Group 2 entitlement.
The DVLA can request a medical at any time if they have concerns about your fitness to drive, regardless of your age.
Drivers aged 70+ who still need C1 or D1 entitlement require a D4 every 3 years.
The examination is thorough but typically completed in 15–20 minutes.
