Drivers can be fined up to £1,000 if the DVLA is not informed about certain medical conditions, which could affect driving. Those who choose not to could be prosecuted if involved in an accident as a result.
Some conditions can result in immediate revocation – these include eyesight problems or seizures. Other conditions mean your licence could be removed if a doctor deems it necessary but this is rarely the case.
Drivers must give up their licence if a doctor has told them to stop driving for at least three months.
Here are some of the conditions listed by the DVLA, which must be disclosed:
High blood pressure
Low blood sugar
Obsessive compulsive disorder
