A motorist has been clocked by Swanley speed cameras driving at 149mph on the M25.
The phenomenal figure is the highest speed recorded in England and Wales between April 2013 and May 2014.
It was revealed following freedom of information requests to 39 police authorities by the Institute of Advanced Motorists (IAM).
IAM chief executive Simon Best said: "149 miles per hour 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."
“Speed limits are a limit. They are not a target to beat."
Magistrates' guidelines on sentencing for speeding include:
- 70 mph road: For driving between 101 and 110 mph. Fine plus 6 points or disqualified for 7-56 days.
- 50 mph road: For driving between 76 and 85 mph. Fine plus 6 points or disqualified for 7-56 days.
- 30 mph road: For driving between 51 and 60mph. Fine plus 6 points or disqualified for 7-56 days.
