A biker undertook a police car as he raced along the A96 at over 100mph.
Police have released video footage of a motorcyclist travelling at high speed through roadworks on the busy route.
John Cumming, 43, was banned from driving for 18 months yesterday and fined £1000 following the incident in September last year.
Officers chased the motorcyclist after he undertook their unmarked vehicle on September 26.
When they tried to pull him over he tried to escape by travelling at speeds in excess of 100mph, overtaking and squeezing between other vehicles to try and escape the officers.
Eventually police chose to stop the pursuit and later traced and charged the driver in relation to the incident.
Malcolm Findlay, General Manager, Aberdeen Roads Limited, said: “We hope that this acts as a deterrent for other road users who may be tempted to disregard traffic restrictions. Our priority is to create a safe environment for our workers and sub-contractors and road users. However, their safety is also dependent upon the responsible driving of all road users.
“Road users should be aware that although construction work may not always be visible to drivers, it may be taking place adjacent to or under the road. The traffic restrictions are invaluable in ensuring our workers – someone’s son, father, daughter or mother – are able to go home safe after they finish work.
“For the remainder of the construction period, we request the road users respect the temporary speed limits and traffic signals in place, for their own safety and that of our workforce.”
Sergeant Steve Manson from the Trunk Road Patrol Group said: “This is one of the worst incidents of Dangerous Driving I have seen, not only did the rider put himself at risk but also other road users as well as the nearby road workers.”
“The Officers attended at Mr Cumming’s house just after the incident and spoke with his wife. Given the type of riding displayed they could easily have been there to pass a death message.
“As part of Police Scotland’s Operation Zenith we are looking to reduce the motorcycle casualty rate and the type of riding shown is exactly what we are looking to target.
“Road Policing Officers will continue to carry out marked and unmarked patrols in the area and report drivers who fail to comply with the speed limits.”
On Saturday 26 September 2015, Officers from the Trunk Road Patrol Group were on patrol in an unmarked vehicle on the A96 between Blackburn and Aberdeen.
