Large parts of Scotland are facing possible travel disruption on Monday, following a Met Office weather warning.
Much of Perth and Kinross, arterial routes in Glasgow and parts of Dumfries and Galloway and the Borders are most at risk from snow and ice.
Transport Scotland's Multi Agency Response Team (MART) will be open during the morning's rush hour.
Its role will be to ensure a co-ordinated monitoring and response system is in place.
The Met Office said rain, sleet and snow were expected to move in from the west during the morning.
A moderate build-up of snow is likely above 250m, with some snow at low levels for a time in the east.
Rain falling onto sub-zero surfaces will increase the risk of ice in the west and at low levels further east.
'No complacency' Transport Minister Keith Brown said the use of MART was in keeping with the Scottish government's "no room for complacency" approach. He added: "Having Transport Scotland, the police, rail operators, road operating companies and the Met Office working side by side and agreeing messages for the travelling public has worked well so far, but we must stay sharp and keep up the good work.
"In the run-up to Christmas, the pressure to keep our transport network running as effectively as possible is even greater than usual - businesses depend on roads and rail for deliveries and the public will obviously be out in numbers doing their Christmas shopping.
"Disruption can never be ruled out, but we have taken a wide range of steps to ensure that Scotland is as well prepared as it can be."
Those steps include working with the Road Haulage Association and Freight Transport Association to update guidance on planning for severe weather.
A hotline has also been introduced so HGV drivers can contact Traffic Scotland to inform them of traction problems they experience on the network.
Mr Brown added: "I would urge the public to continue listening to radio reports and checking the Traffic Scotland website for updates."
