Why the HGV Medical Matters
Every HGV, LGV, PCV, C1, and D1 driver in the UK must hold a valid Group 2 medical certificate (the D4 form) to obtain or renew their vocational licence. The DVLA sets higher health standards for professional drivers than for ordinary car licence holders — covering eyesight, cardiovascular health, diabetes management, neurological conditions, and sleep disorders.
Failing to renew your medical on time — or failing to declare a notifiable condition to the DVLA — can invalidate your licence and expose you to prosecution. The guides in this hub cover every stage of the process: from your first D4 appointment through to renewing at 45, 65, and beyond.
