The Letterkenny to Lifford Road has been closed half a mile on the Letterkenny side of Rossgeir following a crash this morning.
We understand a number of cars have gone off the road following an oil spill, and at least one person has been seriously injured.
Emergency services are at the scene, and Donegal County Council is also assessing the situation.
There are also reports of oil on the road all along the N14, and also on the N15 between Killygordon and Ballybofey.
