Driving a heavy goods vehicle (HGV) comes with a higher level of responsibility. Unlike standard car drivers, HGV drivers operate large vehicles that can pose serious risks if not controlled safely. Because of this, the Driver and Vehicle Licensing Agency (DVLA) enforces stricter medical standards. Understanding what these medical conditions must be reported to DVLA is especially important for HGV drivers. Failing to report a condition can lead to fines of up to £1,000, licence revocation, and invalid insurance. For professional drivers, it can also result in immediate job loss.
What Circumstances Require You to Notify DVLA as an HGV Driver?
For HGV drivers (Group 2 licence holders), the rules are stricter than for regular drivers.
So, what circumstances require you to notify DVLA?
You must report any condition that affects:
- Alertness or concentration
- Vision and depth perception
- Coordination and reaction time
- Risk of sudden incapacity (e.g. blackouts)
Even minor symptoms can be significant when operating large vehicles over long distances. The DVLA provides a detailed A–Z medical conditions list that drivers should regularly review .
