A year ago I've renewed my driving licence which is supposed to expire in 2 years. One month ago I moved to a new address. I've tried to re-registered my address on-line, but was unable... I've sent a form by post to DVLA. Yesterday I've received a questionnaire regarding my diabetes and my insulin control... My diabetes condition didn't change, only my address. Does anybody know if you need to go through all these diabetes things again if you change an address?
