Why Do HGV Drivers Need a D4 Medical?
Driving Heavy Goods Vehicles (HGVs) in the UK is a demanding responsibility that requires excellent health and full concentration. As a result, the Driver and Vehicle Licensing Agency (DVLA) requires HGV drivers to complete a D4 medical examination to prove they’re medically fit to operate large vehicles.
Whether you’re a new applicant or renewing your licence, you must submit the D4 form, as it plays a vital role in your application.
