A new speed limit and plans for average speed cameras have been announced for a busy stretch of the A90.
The 50mph limit will be enforced on the route at Charleston, south of Aberdeen, from Wednesday.
But Traffic Scotland has also revealed it has plans to install average speed cameras along the same stretch.
The new speed limit will be in force 24 hours a day as part of work on the Aberdeen Western Peripheral route.
A Transport Scotland spokesperson said: “The works due to be undertaken at Charleston are extensive and it is therefore necessary to implement comprehensive traffic management measures to ensure the safety of road users and construction workers.
“It will take time for road users to become accustomed to the new restrictions at Charleston and we are therefore strongly encouraging road users to apply more caution than usual when driving through or nearby this section of the A90.
“Road users should also observe the 50mph speed restriction and road signage to enhance their safety, as well as the safety of others.
“Road users may find it useful to plan their journeys in advance.”
