Thousands of foreign motorists who receive driving penalties in England get away scot-free as police struggle to track them down, a Freedom of Information request has revealed.
Statistics show that in the last four years, £7,293,480 worth of speeding fines has been amassed by foreign-registered vehicles.
Other penalties that have gone un-punished include running lights, using a mobile phone whilst driving, not wearing seat belts and failing to comply with traffic laws.
Lib-Dem leader Tim Farron called the police's inability to track these offenders an 'unacceptable' failure, adding that British taxpayers had lost out as a result.
"We should not be losing over £7million in speeding fines, we need to be doing much more to recoup that money," he said.
"This lackadaisical out-of-sight-out-of-mind attitude to the whole problem is frankly unacceptable.
"That cash could be used to fix our crumbling roads or used to help bring down the sky-high cost of motoring."
A number of police forces across the country were named and shamed in the report, with Thames Valley amongst the worst, letting 9,234 speeding foreigners off since 2012.
Durham Police sat on the bottom of the list, with 40 drivers let off in 2015.
