The IAM has published what it describes as “the worst examples of excessive speeding” caught on speed cameras across England and Wales in 2014.
The highest recorded speed was 146mph by two different drivers on the M25. There were three other instances of speeds of 140mph or more being recorded: 145mph on the M6 toll road, 141mph on the A1 and 140mph on the A5.
However, the IAM says the “most astounding figure” was 128mph recorded on a 30mph road in East Grinstead in Sussex.
The statistics come from a FOI request made by the IAM to police forces in England and Wales.
The IAM believes that “an improvement in driving skills and attitude” is the key to reducing the numbers of people killed and injured on UK roads. It advocates advanced driving and riding tuition and continuous development in skills to help achieve this.
The IAM also supports the use of speed 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.
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.”
