A reader sent me this link to an article which suggests that 1.6 million motorists risk a £1,000 fine because they aren’t aware that the photocard part of their licence has an 
expiry date on it. Apparently, 1.6 million have already missed their deadline, and another 2.9 million look likely to.
The photo on your licence has to be updated every 10 years, and this applies whether you are a practising driver or not. Apparently, 13 million licences will need to be updated over the next 5 years (I know mine is due in 2014).
A third of people interviewed appeared not to know that their licences had already expired. About 10 million people don’t know when theirs expires. And 14% of expired licences have been that way since 2009 or earlier!
An expired photocard could get you a fine of £1,000. The survey which found all this out also discovered that only 29% of drivers know of the fine. About 41% had no idea of the consequences of having an out-of-date licence.
The article points out that an expired photocard means that it cannot be used as a form of ID. That alone should get many people to pull their fingers out and keep it updated.
