Freezing temperatures have seen a spate of crashes on roads across Scotland.
Grampian Police said most routes were passable but warned motorists to take extreme care as heavy snow which fell on Wednesday had thawed and then frozen overnight as temperatures plummeted.
Three people were taken to Aberdeen Royal Infirmary on Thursday after two separate crashes on the A90 at Portlethen and Balmedie.
Traffic was also heavy on the A82 at the Bridge of Orchy in Argyll and Bute after an accident in hazardous road conditions.
Snow gates remain closed on the A939 at Tomintoul, Cockbridge and between Corgaff and the Lecht ski centre, as well as on the B974 from Banchory to Fettercairn.
In Aberdeenshire Towie School was closed and Ellon Primary was partially closed to pupils. School transport was also not running to a number of schools.
The Met Office has told people to be prepared for potentially treacherous conditions in Strathclyde, Grampian, the Highlands, the Western Isles, Tayside, Central and Fife.
Forecasters have warned there could be significant disruption over the M8 corridor to the east of Glasgow, across Perthshire and over much of inland eastern Scotland.
