Controversial average speed cameras on the A90 are set to be switched on at the end of the month.
Cameras have been placed along the 50-mile stretch from Stonehaven to Dundee and will go live on October 31.
The £2 million camera system will see 15 cameras installed on both sides of the carriageway.
Cameras are being introduced in a bid to lower the number of deaths on the main stretch of road connecting Aberdeen and Dundee.
A similar scheme has been introduced on the A9 between Dunblane and Inverness.
Humza Yousaf, Minister for Transport and the Islands, said: “The average speed camera system on the A9 continues to demonstrate a radical improvement in driver behaviour.
“I am satisfied that the A90 average speed camera system will be just as successful in improving road safety.
“I can confirm the system will go live on October 31, in line with the previous timescales provided by Transport Scotland.”
Critics of average speed cameras believe they are more about making money through fines than improving safety, but figures from the A9 show the number of fatal and serious-injury casualties has fallen by around 40% since cameras were introduced in 2014.
Councillor George Carr, who represents the Mearns area, has been critical of the installation of the cameras.
He said: “I think putting cameras in is the wrong thing to do. I just think it is the wrong thing to be putting in place, the Scottish Government needs to improve the junctions on the A90 first.
“At the moment the junctions are not fit for purpose. The Laurencekirk one needs work to start soon.”
The news comes after the Scottish Government revealed statistics showing the number of deaths and serious incidents on roads across the country.
The North-east was the worst for serious incidents across the 13 police divisions, with 251 taking place.
The area was also the second worst in terms of road deaths in 2016, with 26. Lothian and Borders was the worst with 30.
