Martin Lewis's empire makes regular forays into motoring law issues which they declare as "surprising", "little known" or "new laws", none of which is usually true.
They (along with many other sources) made a complete hash of what they called "new speeding laws" in April 2017, when they declared that thousands of drivers face draconian fines and bans for speeding. All that had happened was that there was a slight change to Magistrates' sentencing guidelines for the most serious of the cases which were dealt with in court. There were no new laws, no new procedures and no changes to the fixed penalty system under which the vast majority of speeding offences are dealt with. But it made good copy.
So with this. Photocards have always only been valid for ten years. Very few people are penalised if they fail to renew their photocard. Although the maximum penalty is a fine of £1,000, it is usually dealt with by way of a fixed penalty of £100. The expiry of a photocard does not cancel the licence holders entitlement to drive which, unless restricted for medical reasons, lasts until the holder is 70.
