The number of people fined for speeding has hit a four-year high, as new digital cameras trap more motorists.
Courts handed out115,549 fines in 2013 – the highest number since 2009, figures released by the Ministry of Justice show.
South Wales has seen one of the biggest increases, with the number of people fined tripling last year to 6,491, from 2,181 three years earlier.
The number of offenders has also risen in that period by almost 1,000 in both South Yorkshire and Lincolnshire – and by close to 2,000 in Staffordshire.
While London saw the most people fined last year, the figure for the Metropolitan Police area has fallen to 7,736.
That is the lowest level in five years.
Those convicted of a speeding offence must pay a minimum of 100 and get three penalty points added to their licences.
A Department for Transport spokesman said: “Speeding can have devastating consequences and it’s right that drivers should abide by the speed limit.
“These fines were issued at the discretion of the magistrates and show the number of fines issued is in decline across many police force areas.”
AA president Edmund King said the introduction of digital cameras mean the devices are now working all day long.
He told the Telegraph newspaper: “It (the rise in speeding fines) is a reflection that cameras are more efficient than ever.
“In the past, cameras in London they would only take valid pictures for a quarter of day and it was pot luck whether you are fined. The cameras are now working 24 hours a day.”
Last week the Institution of Engineering and Technology said in the future the speed at which cars can travel may be altered to fit the driver’s experience, and the development of driverless cars may mean an end to speeding.
“Within 15 years, we predict that the performance of cars could be altered to fit the driver,” the institution said.
“Speeding may become a thing of the past as cars are likely to be fitted with speed-limiting devices.”
This year this year a speed camera in Cardiff generated more than an estimated 800,000 worth of fines in just six months.
According to road safety group GoSafe Wales, the device on the junction of the city’s Newport Road and Colchester Avenue caught 13,624 speeding motorists and a further 146 running red lights between January and June.
