What Are the DVLA HGV Medical Requirements in the UK?
The Driver and Vehicle Licensing Agency’s Group 2 medical fitness criteria define the physical, sensory and cardiovascular standards HGV drivers must meet to ensure road safety and operational competence. Drivers must undergo a formal medical examination, complete a D4 medical form and demonstrate fitness across cardiovascular, neurological, sensory and metabolic parameters. Meeting these requirements not only secures licence issuance or renewal but also protects drivers against sudden incapacitation at the wheel.
Who Needs an HGV Medical Examination?
- New licence candidates must pass an initial medical before theory and practical tests.
- Existing licence holders aged under 45 renew every five years; those 45–65 renew every five years; over 65 renew annually.
- Drivers changing from Category B to Group 2 status require medical clearance regardless of age.
Completion of this first step paves the way to understanding specific fitness criteria.
What Are the DVLA Group 2 Medical Fitness Criteria?
DVLA Group 2 medical standards encompass four core domains—cardiovascular health, neurological stability, metabolic control and sensory acuity—to safeguard HGV operation.
- Cardiovascular Health
- Neurological Function
- Diabetes Management
- Vision and Hearing
These domains integrate to certify that professional drivers remain capable of sustained, alert, incident-free driving over long distances.
Assessing fitness to drive – a guide for medical professionals
Medical standards for Group 2 licence holders, which include drivers of large lorries and buses, are considerably more stringent than those for Group 1 drivers. This is due to the increased size and weight of the vehicles and the extended periods occupational drivers spend at the wheel. The DVLA, for example, prohibits Group 2 licensing if a driver’s left ventricular ejection fraction is below 40%.
