Drivers could be running the risk of a fine of up to £1,000 due to an existing medical condition.

About a million motorists are estimated to be on the road with a health issue they haven't flagged to the Driver and Vehicle Licensing Agency (DVLA).

According to the agency, you must tell them if you're suffering with any of the "potentially notifiable" conditions on its list.

And the list doesn't just run to a few simple things, it's an extensive A to Z of diseases, syndromes and ailments.

Failing to report a condition to the DVLA could see you slapped with a £1,000 fine and invalidate your insurance.

Although the condition may appear on the list, it does not automatically mean the DVLA will decide it would curtail your driving ability. Click here for more information.

What happens after you tell DVLA

You’ll usually get a decision within six weeks. You’ll get a letter from DVLA if it’s going to take longer.

The DVLA might:

  • contact your doctor or consultant
  • arrange for you to be examined
  • ask you to take a driving assessment, or an eyesight or driving test

You can usually keep driving while DVLA are considering your application.

Contact the DVLA if you cannot find your condition.
