You may expect the biggest speeding offences to take place on motorways, but 19 of the top 20 fastest motorists caught in Scotland were driving on A roads. Topping the list for the highest speeds recorded by police, was a driver who hit 139mph on a 60mph stretch of carriageway, figures obtained by road safety charity, the Institute of Advanced Motorists (IAM), reveal.
Statistics sourced by the IAM through a Freedom of Information request to Police Scotland revealed the top 20 most serious speeding offences from the 15 months between April 1 2013 and June 30 2014. The highest speeds captured by both fixed and mobile speed cameras for these drivers ranged from 114mph to 139mph.
The second highest speed captured was 129mph on a 70mph A road, recorded by a fixed speed camera. Coming in third was a driver who was caught driving at 127mph by a mobile speed camera.
IAM chief executive Simon Best said: "These speeds show there are still drivers out there displaying a contempt for the law and for the safety of their fellow road users.
"This is made doubly worse by the fact the vast majority of the incidents took place on A roads, therefore putting oncoming motorists, motorcyclists, cyclists and pedestrians at greater risk."
Six further drivers were caught travelling at 120mph or over, with another 11 hitting 114mph or more. In comparison, the highest speed recorded in England and Wales stands at 149mph, with a total of seven drivers caught driving at over 130mph over the same time period.
The two highest speeds recorded in England, both more than twice the speed limit, were recorded on the M25 near Swanley. These figures were announced by the IAM in May, following Freedom of Information requests to 39 police authorities.
