Motorists are being urged to take extra care on the roads in Donegal this Friday morning.
Icy conditions are reported in many areas, particularly around Letterkenny, including on the N13 from Drumkeen and Manorcunningham towards the town, and in the Kilmacrennan area.
Council gritters were dispatched to all main routes from 6am, but drivers are being warned to assume that no road is ice-free.
Slow down and take extra caution on all routes.
