Can DVLA take my license?
The DVLA can take your license if you have a medical condition or disability that affects your driving. They may also give you a shorter license, require that you have a vehicle that is adapted for special controls or that you must stop driving entirely. If you declare a medical condition and the DVLA say that you can no longer drive, they will give you a clear medical reason for you. They will also tell you if you can reapply for it at some point or not.
If you think they have unfairly taken your license, there is an appeal process where you need to show proof that you meet the driving requirements standards. You also need to send the details of their decision letter. Send this to the DVLA in Swansea and they will consider it, but they may not change their decision.
