One motorist was caught speeding at 149mph on the M25 while another was clocked driving at three times the legal speed limit in 30mph zones outside of a primary school last year, according to new figures.
The astonishing statistics, which have been uncovered after the Institute of Advanced Motorists submitted a Freedom of Information request, reveal the highest speeds at which drivers have been caught by traffic enforcement cameras.
One motorist was caught hitting 149mph on the M25 near Swanley in Kent, while another motorist was caught travelling at 146mph by the same camera in the period between April 2013 and May 2014.
Two further drivers were clocked at 127mph on the same stretch of motorway.
The Freedom of Information request also revealed that the highest speed recorded on a 30mph road was 96mph in Leam Lane in Gateshead, Tyne and Wear – more than three times the legal limit.
Another careless driver was clocked reaching 94mph in a 30mph zone near New York Primary School on the B1192 Langrick Road in Lincolnshire.
Both 50mph and 60mph speed limits also failed to deter speeding motorists as one driver was captured on the 50mph stretch of the A414 Stanstead Abbotts, Hertfordshire, at 119mph, while another hit 127mph on the 60mph A413 Wendover bypass in Buckinghamshire.
IAM chief executive Simon Best said: "The current guidelines on sentencing for excessive speeding offences are out of sync with modern roads, modern vehicles and society's view of the value of lives lost in crashes.
"We all share the roads with these speeding drivers and the government must crack down on them with more consistent penalties and tougher measures to break their addiction for speed."
The group added that efforts to make speeding as socially unacceptable as drink driving had failed.
Best added: "Speed limits are a limit. They are not a target to beat. Unfortunately this message has not got through to many motorists."
