A motorist has been caught speeding at 149mph.
The offence, on the M25 near Swanley in Kent, was captured by a speed camera and was the highest recorded speed during the period April 2013 to May 2014.
This offence, and others, were revealed in data received from police under a Freedom of Information Act request from the Institute of Advanced Motorists (IAM).
Other findings showed:
:: The highest speed recorded on a 30mph road was 96mph in Leam Lane in Gateshead, Tyne and Wear;
:: The highest on a 50mph road was on the A414 Stanstead Abbotts, Hertfordshire, where a motorist clocked 119mph;
:: The highest on a 60mph road was 127mph on the A413 Wendover bypass in Buckinghamshire.
IAM chief executive Simon Best said: "A speed of 149mph equates to nearly two and a half miles in a minute. If anything goes wrong at that speed, you're unlikely to walk away and you are a grave danger to the innocent road users around you."
He went on: "Speed limits are a limit. They are not a target to beat. Unfortunately this message has not got through to many motorists and it's clear that efforts to make speeding as socially unacceptable as drink-driving continue to fail.
