The three drivers caught furthest over the speed limit in Norfolk and Suffolk in 2014 were all snapped by the same speed camera.
A survey by the Institute of Advanced Motorists of the top speeds caught on camera by police across the country reveals that a speed camera on the A140 near Coddenham, where the speed limit is 50mph, has caught drivers doing 114mph, 115mph and 119mph, or 69mph over the limit, which was also the highest speed recorded anywhere in Suffolk.
In Norfolk the highest speed recorded was 120mph on the A11 at Ketteringham, which was 50mph above the limit, but a driver was also pictured doing 116mph on the A1065 at Mundford, which was 56mph over the limit there.
But these East Anglian speeders almost sound safety conscious compared with the worst recorded nationally.
Britain’s two fastest speeders were caught at 146mph, both by Kent Police 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 the most astounding figure was 98mph above the limit at 128mph on the 30mph London Road, East Grinstead.
Sarah Sillars, IAM chief executive, said: “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, which believes improving driving skills and attitude is the key to reducing the numbers road deaths and injuries, 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 road works
