Martin Lewis issues warning as millions could face a hefty fine due to little-known driving licence rule

Martin Lewis has sounded the alarm that two million drivers have expired licences, with older drivers over 70 being particularly at risk

Martin Lewis warned millions could face fines from the DVLA due to a little-known rule about driving licences. Two million drivers may have an expired licence, with older drivers over 70 being particularly at risk.

The Driver and Vehicle Licensing Agency (DVLA) states you must renew a photocard licence every 10 years, and failure to do so could see drivers paying a fine of up to £1,000. However, the rules are different if you are aged over 70 as you will have to refresh your licence every three years, rather than the usual ten.

The star of The Martin Lewis Money Show warned: "The cards and products in your purse or wallet are a window on your finances, so a regular check-up of what you're holstering is important. And while many phones and watches are gradually morphing into wallets, my Twitter purse poll showed that just over two-thirds still take a physical purse/wallet out with them. So here are my tips, whether you're a cash king or a digital doyenne."

He added: "Has your photo driving licence expired? Two million have. They usually expire after 10 years - so check its SECTION 4B to see. Our driving licence check guide has full info on how to renew safely and cheaply and avoid a hefty fine."

This warning comes after data from the DVLA found that more than two million licences were out of date across all age ranges. In a newsletter from Mr Lewis, the creator of the MoneySavingExpert.com website, he warned: "A quick check now could save you a fine of up to £1,000 if your photocard's expired."

Renewing your driving licence online will cost you £14, or £17 if you choose to do it by post. To renew online, you'll need a UK passport or the document you used to set up your online immigration status.

If you don't have either of these, you'll need to apply at a Post Office or by post, according to the government. If your name or title has changed, you can't apply online and will need to renew your licence by post.
