A number of people were taken to Letterkenny University Hospital last night following a crash close to Drumoghill.
The accident, which is understood to have involved three vehicles, happened at the Galdonagh turn-off on the main Letterkenny to Lifford Road.
The road has since been cleared but motorists are advised the road could still be slippy.
It is not understood any of those taken to hospital were suffering from life-threatening injuries.
