Wintry weather has hit parts of Scotland with road conditions in the north described as "treacherous".
Grampian Police said a number of vehicles had already had collisions while a lorry had jack-knifed closing part of the A920 between Huntly and Dufftown.
Forecasters expect the snow and sub-zero temperatures to last around a week.
A spokesman for Grampian Police said: "Most roads within the Grampian region are badly affected by the adverse weather conditions. On lower ground there are large amounts of surface water, which has turned to ice in some areas.
"Inland, on higher ground, roads are badly affected with snow. Most are passable with care. Driving conditions are however described as treacherous.
"There have been several minor road traffic collisions across the area. One jack-knifed lorry has caused a road closure on the A920 between Huntly and Dufftown. Drivers are urged to allow extra time for their journeys and exercise extreme caution on the roads this morning. They should drive according to the road conditions and make sure they are prepared for the journey."
A spokesman for Northern Constabulary said all roads in their area were open on Wednesday.
"However, on some roads in the Caithness and Sutherland, and Badenoch areas there is a light accumulation of snow and ice," he added
Brendan Jones a forecaster with MeteoGroup, the weather arm of the Press Association, said: "We are just getting into the cold spell. We haven't really started with the cold snap yet. It is getting an awful lot colder over the next few days everywhere in the UK with the lower temperatures to last around about a week.
"There are a few centimetres of lying snow on the high ground in Aberdeenshire. We are talking snow showers overnight rather than heavy snow. At the moment it is confined to the north of Scotland, really. Lowest temperatures overnight were in south-western Scotland. Places in Ayrshire and South Lanarkshire and Dumfries and Galloway reached around -4 centigrade, parts of southern Kintyre reached -3 due to the clear skies."
