Motorists are being urged to avoid the Letterkenny-Drumkeen back road due to treacherous icy conditions.
Despite the overnight thaw, there is still a lot of ice on the road which is located on high ground.
One motorist, who is stranded at the scene, said there are at least eight cars off the road there.
“The road is like a sheet of ice,” they said.
“Road users need to beware – both guards and gritters were contacted. Gardai have just arrived on the scene.”
Locals with tractors are also helping the stranded motorists.
