A biker who recorded a speed of 79mph above the legal limit on the road from Keith to Huntly was never caught – because the camera was unable to capture his number plate.
The remarkable speed of 139mph was recorded on the A96 and topped a list of the top speeders in Scotland between April last year and June 2014.
Figures released on Monday by the Institute of Advanced Motorists (IAM) through Freedom of Information requests to Police Scotland showed that of the top 20 speeds recorded on Scottish roads only one was on a motorway.
IAM Chief Executive Simon Best said that motorists were continuing to treat speeding laws “with contempt” and were putting other road users at even greater risk.
Mr 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.”
The same survey revealed that the highest speed recording on a road in England and Wales was 149mph on the M25 in Kent.
