I recently received a 'heads - up' message from a friend regarding my photo driving licence. It is now over 10 years since they were first introduced and many have now expired; the date of expiry is shown as 4b on the photo side of the licence. When it expires you must renew it at a cost of £17.50 and although renewal letters are sent, if the records at the DVLA are not accurate, you may not receive any notification. Apparently only about three-quarters of the licences that have now expired have actually been renewed. The old paper licences were valid until the age of 70 and many motorists believe that still to be the case; it isn't! (I've checked mine and it expires in three months.)
