A speed camera on the A40 in north west London is Britain’s most prolific - snaring almost 50,000 drivers in 12 months, according to new research.

More than 1.74million motorists were snapped by roadside cameras across the UK raising £45.7m in fines for the financial year 2021/22.

One on the A40 dual carriageway between Long Drive, Acton and Welland Gardens, in Perivale, caught 49,050 speeding cars - double that of any other camera, says price comparison site

Researchers sent Freedom of Information requests to all police forces to obtain the number of intended prosecutions for speeding offences captured by cameras in their area.

Around 36 responded with figures - including the Metropolitan Police - meaning the full UK picture is unknown.

Cameras on the M25 between Junctions 7 and 16 in Surrey and M4 near Bristol are next in a league table with 23,134 and 18,317 speeding offences respectively.

A further 14,423 were caught on the A282 Dartford Tunnel Approach Road, Kent.

Sussex Police snared 14,172 on Lewes Road on the junction with Coldean Lane, Brighton.


Despite so many drivers being flashed, police data shows only 457,232 were given a £100 fine and three penalty points on their licence.

Instead, 698,115 drivers opted to take a speed awareness course.

The scheme typically costs around £100 but participants escape having points which are likely to increase insurance premiums.

According to Confused, there are currently more than 1,300 operating speeding cameras on our roads.

Alex Kindred,’s car insurance expert, said: “Our research shows that nearly half of drivers have had a fine for speeding in the past. “Although some motorists might feel that speed limits are an inconvenience, they’re there to ensure our roads are safe for all.

“If caught speeding, motorists could land themselves with a fine, points on their licence or even a driving ban.

“In some cases, drivers could attend a speed awareness course instead, but the punishment depends on the seriousness of the offence. A speeding fine or points added on to your licence could also lead to an increase on your car insurance costs.

“If you’re faced with a fine, there’s a chance it could be calculated based on your salary, and may be heftier than you first think.”
