You can be fined up to £1,000 if you don’t tell DVLA about a medical condition that affects your driving. You may be prosecuted if you’re involved in an accident as a result.

Car or motorcycle licence

You don’t need to tell DVLA. You should stop driving for at least 1 month and only restart driving when your doctor tells you it’s safe.

Bus, coach or lorry licence

You must tell DVLA if you have heart valve disease or a replacement valve. Fill in form VOCH1 and send it DVLA. The address is on the form.

If you have valve surgery you must stop driving for at least 3 months and only restart driving when DVLA says you can.
