DVLA take very seriously the removal of a driver’s vocational licence and will only revoke (withdraw) a licence once there is definite evidence of a relevant medical condition. When a driver first notifies DVLA of an illness, DVLA will write back to the driver acknowledging receipt of the notification, and will start making medical inquiries. This will often include writing to the person’s GP or consultant. At this stage they will generally NOT revoke the driver’s licence. This means that even though a driver may have a serious medical condition, at this stage, he will probably still hold a current driver’s licence. However, no driver is permitted to drive any vehicle if he is medically unfit to do so, so once a driver knows he has a medical condition, whether or not he holds a valid licence to drive, he must only drive if he is fit to do so. In cases of uncertainty, he should take advice from his doctors. The fact that he may still have a valid licence does not automatically mean he is permitted to continue driving.
