Britain’s two worst speeders were caught at 146mph on the M25, according to statistics released by the Institute of Advanced Motorists (IAM).
The IAM has lifted the lid on the worst examples of excessive speeding caught on safety cameras across England and Wales in 2014.
Of the two speeding drivers on the M25, one was travelling anti-clockwise at Junction 5 at Clacket Lane Services, the other going clockwise at Swanley.
There were three other instances of speeds of 140mph or more being recorded; 145mph on the M6 toll road (70mph limit), 141mph on the A1 Great Ponton Northbound road (70mph limit) and 140mph on the A5 Crick Eastern Verge road (60mph limit).
But perhaps the most astounding figure was 128mph recorded on London Road, East Grinstead a 30mph road, exceeding the limit by 98mph.
The statistics come from a Freedom of Information request made by the road safety charity to police forces in England and Wales. The IAM asked each police force for the highest recorded incidences of speed caught on safety cameras in 2014, including locations, speed limits and top speed in each case.
Of the 41 police force areas the IAM requested the information from, 36 responded. All forces recorded at least one top speed over 110mph with the exception of City of London, Cleveland, Greater Manchester, Northumbria, West Midlands and South Yorkshire.
Wales’s top speeder was an individual who recorded 136mph on the A5 Ty Nant to Dinmael road in Conway, which has a 60mph limit.
London’s worst speeder was recorded at 123mph on a 30mph road by the Metropolitan Police.
The highest figure recorded in a 50mph zone was 120mph, by Nottinghamshire Police on the A631 Beckingham Road.
And the worst speed caught on a 40mph road was 115mph on A10 Great Cambridge Road in Cheshunt, Hertfordshire.
Sarah Sillars, IAM chief executive officer, said:It is disheartening, to say the least, that some road users are showing such disregard for the safety of all other road users pedestrians, cyclists, motorcyclists and other drivers.
At speeds of 140mph, an individual is travelling at nearly two-and-a-half miles a minute. At that speed, it is simply impossible to react to anything that might happen in front of you.
It is also impossible to handle corners, gradients, street furniture and junctions with any effectiveness. In short, all these individuals are playing with their own lives and others they are all accidents waiting to happen and it requires a major shift in the attitudes of these people to think about safety.
The IAM supports the use of safety camera systems at collision hot spots, on roads with a speed related crash record and at areas of proven risk, such as motorway roadworks.
