More than 900,000 drivers are at risk of £1,000 fines for failing to renew their photocard licenses which expired last year, an investigation has revealed.

The agency found that as of September 3, 926,000 drivers had cards that had expired in the 12 months to the end of August, representing 2% of all drivers.

A small proportion of the 926,000 probably stopped driving without warning DVLA.

The investigation also found that 2.5 million drivers are likely to have renewed their photo card after it expired or within 56 days of its expiry last year.

Photo cards must be renewed every 10 years to ensure the image is a true likeness of the driver, the expiry date is usually shown in section 4b on the front of the cards.

If a driver fails to return an expired license to the DVLA, it is an offense under the Road Traffic Act 1988 and can be punishable by a fine of up to £1,000.

Z DVLA by exchange they write to people 56 days before their license expires to remind them to renew.

However, many drivers miss the letters because they do not notify the agency of their address change.

In addition, if a person renews late, but still renews, he will not be fined.

Philip Homme of the RAC Foundation said: “There are good reasons to keep licenses up to date beyond the basic legal requirements.”

Adding: “The renewal also gives people a chance to assess whether they are fit to drive and we think there is a case for linking a mandatory eye test to the process to make sure we are all safe on the road, although the Government should help keep the lowest possible costs for motorists.’

The DVLA recommends people to update on their official website as it is the fastest and cheapest way.

Applications cost £14 and are usually processed within five days.

A postal extension costs £17, while the Post Office charge is £21.50.
