Vans equipped with speed cameras will target two new sections of road in the Highlands.
The move has been prompted by high levels of accidents and casualties on the A9 between North Kessock and Tain and Mid Clyth on the A99.
The vans are operated by the Northern Safety Camera Partnership (NSCP) - which involves Northern Constabulary and Highland Council.
The cameras are often used along the A9 south of Inverness and on the A82.
According to the figures, the cameras have been detecting about four offences an hour on average since 2008.
The NSCP said improved behaviour of motorists on target routes could be linked to the presence of the camera van.
The details are contained in a report due to go before local councillors next week.
