The influx of high-tech digital speed cameras has seen the the number of motorists trapped surge to 115,000 in the last year - the highest number since 2009.
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 total number of motorists caught speeding is believed to be far higher, as the figures only take into account those summoned to court for failure to pay fines and where speed was particularly excessive.
|Police force area||Offenders fined||Police force area||Offenders fined|
|Cleveland||813||Devon and Cornwall||2,410|
|West Midlands||1,442||Avon and Somerset||3,925|
|Total England and Wales||115,549|
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.
'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.
A spokeswoman for the Department for Transport 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.'
