SNOW and ice brought disruption to roads today as the country faced its first bout of wintry weather.
After a mild November, commuters faced delays on the roads after snow and sleet fell overnight
A fleet of 130 gritters were out overnight to treat roads and 3000 tonnes of salt were used.
But the M74 in South Lanarkshire was down to one lane southbound after an HGV jack-knifed earlier today.
The A74 in Dumfries and Galloway was also reduced to one lane when another lorry jack-knifed.
Motorists were warned of black ice on the A9 between Plean and Falkirk.
The A809 in Stirling was described as "very icy", as was the A905 in the Throsk area.
Stornoway airport was closed leading to delays on flights to and from Glasgow, Edinburgh, Inverness, Benbecula and Aberdeen. It was expected to reopen later. Edinburgh and Glasgow airports were operating normally.
Transport Minister Keith Brown said: "We've already seen some wintry weather across much of Scotland and, while it is not as severe as this time last year, we cannot afford to be complacent.
"Both the Scottish Government Resilience Room and the Multi-Agency Response Team are operational, and I have been in the Traffic Scotland Control Centre throughout the morning.
"A fleet of 130 gritters and winter patrols were out throughout the night to treat roads and we used 3000 tonnes of salt.
"While we are all working hard to keep Scotland moving and get back to normal where disruption does occur, it's important the public continue to play their part too. Plan your journey, listen to police advice and check available travel updates."
The Met Office issued severe weather warnings for most of Scotland as well as Northern Ireland and parts of northern England.
Seventeen primary schools in South Lanarkshire were closed because of the weather.
North Lanarkshire Council said all of its schools were open but it warned that travel may be difficult.
Highland Council said seven schools were shut, with parents being asked to collect their children as soon as they could.
In Aberdeenshire, Crossroads Nursery in Durris was closed, and the council said transport to six others had been disrupted.
Meanwhile, Scotland's ski centres said they did not get enough snow to justify opening, although Nevis Range saw 10cm fall and is now considering opening early this year.
Cairngorm mountain, Glencoe, Glenshee and Lecht Ski Centre all reported a "dusting" of snow but said it was not enough for winter snow sports yet.
A spokesman for Glenshee said: "We have had very little snow, just a dusting and not enough to do anything with. We will just keep waiting. It's all we can do."
