More snow and ice to blanket Scotland after school closures
Commuters have been warned more snow and ice will sweep across Scotland after delays and school closures.
A Met Office yellow weather warning covering a large stretch of the country has been extended until 11:00 on Wednesday.
Regions affected are central, south west, Tayside, Fife, Highlands and islands, Lothian, Borders and Strathclyde.
Up to 10cm (4in) of snow on high ground has been forecast.
Meanwhile up to 2cm (1in) of snow is expected to lie in some lower areas.
It is thought snow will affect eastern parts of Scotland, particularly Fife, Lothian and the Borders.
There has already been significant snowfall in some parts of the Highlands and the snow gates on the A939 between Cock Bridge and Tomintoul were closed on Monday afternoon.
Snow caused some difficulty for drivers on the M9 and A9 in central Scotland early on Tuesday. There were also delays on the M77.
Highland Council took the decision to close 13 primary schools and nurseries and one high school because of the weather.
More than 100 gritters were deployed across the areas of the country where the most snow and ice was expected.
Transport Scotland praised drivers for their caution , reporting very few accidents on Tuesday morning.
Stein Connelly of Transport Scotland told the BBC's Good Morning Scotland programme: "We've got to thank people for driving to the conditions.
"You may have noticed the queues are a little longer this morning, people are slowing down and leaving extra that bit of braking distance and that's resulted in very little minor bumps that we'd normally get.
"The actual trunk roads are running free just now. We've had some heavy fall up in the north west of Scotland and we've had this fall throughout the central belt going across to the east.
"It's still challenging driving conditions - we'd ask people to slow down and drive to those conditions."
Advice on the Met Office website said: "Showers will turn increasingly to snow on higher ground then to lower levels later in the night and on Tuesday morning.
"Five to 10cm of fresh snow is expected above about 200m with a cover of 1 to 2cm at lower levels."
It comes after a warning for ice was issued in the north east until 12:00 on Monday.
Glasgow Airport urged passengers to take care travelling to and from the airport and to check with their airlines for flight updates.
Aberdeen Airport also used social media to advise people to allow extra time for their journeys and to take care on the roads.
And ScotRail asked passengers to check their journey before they travel.
