A fleet of gritters is testing new ice sensing technology on Scotland's roads in an effort to improve the country's winter resilience.
The pilot scheme has equipped a fleet of 15 vehicles with mobile ice sensors designed to provide drivers with road surface and outside air temperature information.
It is hoped that the data will help gritter drivers identify cold spots and co-ordinate responses to treat them.
The scheme, which was launched by transport minister Keith Brown, spent nearly £100,000 on the 50 sensors, according to the Scottish Government.
It is part of a six-point plan to improve the response to harsh weather, drawn up following the heavy snow that led to gridlock on some of the country's busiest trunk routes.
Mr Brown said: "The new kits will provide additional real-time information about temperatures on the network, allowing for targeted response - which will now be made within 30 minutes for priority routes with high traffic volumes.
"These new measures will provide Transport Scotland and road operating companies with more tools to help tackle the effects of severe weather, keeping our road network moving and Scotland open for business."
