A report released by the Institute of Advanced Motorists (IAM) revealed the worst speeding offenders with a motorist caught going 128mph in a 30mph zone while another was caught driving at 146mph. These instances were caught on tape and occurred on the M25. The report also shows three other incidents where drivers were recorded travelling at least 140mph.

IAM chief executive office Sarah Sillars said: "It is disheartening to say the least that some road users are showing such disregard for the safety of all other road users.

"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."

She went on: "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."

Meanwhile, IAM says that improving driving skills and attitude are two key factors in reducing the number of accidents that stemmed from speeding.
