Black ice turns roads in Aberdeenshire to glass
Motorists in Aberdeenshire are reporting difficult driving conditions on several rural roads as a result of black ice.
The A947 between Fyvie to Turriff and Newmachar and Old Meldrum is understood to be incredibly slippery.
Meanwhile, the B999 is currently closed at Potterton.
Snow gates on the A93 at Braemar and the Spittal of Glenshee were closed due to the large volume of snow on the road. But on Sunday afternoon, they were reopened.
However, snow gates on the A939 between Tomintoul and Cock Bridge, and another at Cairn O’Mount remain shut.
Motorists are being urged to drive with care and plan ahead amidst the freezing conditions.
