Transport ScotlandTemporary average speed cameras have gone live on part of the N5C00 route in the Highlands.
The cameras have been put in place on a ten-mile stretch of the A836 between Reay and Thurso due to concerns over speeding and increased traffic volumes.
Police Scotland said they are now able to place cameras in previously inaccessible locations through the use of renewable energy.
The cameras will be the first to use a combination of solar and bio-methanol sources and will be powered off-grid.
STV NewsEric Dunion, North Safety Camera Unit manager said: “Our priority is firmly focused on helping to reduce road casualties and improving road safety by slower motorists down and making them think about their driving behaviours.
“The introduction of these new temporary cameras on the A836 will hopefully do just that.”
Average speed cameras monitor drivers over the length of road by recording how fast they are travelling at two different points.
They have been in place on the A9 since 2014 after being introduced to improve safety on the busy route.
