A full list of the common conditions that drivers must tell the DVLA about have been revealed.

Every year, thousands of people are injured in road collisions across the UK.

While some incidents may be minor, motorists who suffer a medical episode while behind the wheel could lead to a fatal loss of control.

What does the DVLA need to know - and why?

The DVLA (also known as the Driver and Vehicle Licensing Agency) requires drivers and motorcyclists to inform them of certain medical conditions.

If you have some conditions - you must declare it to the DVLA – however, for other less serious conditions, motorists should only flag it up to the agency if it affects your driving.
