Motorists are being advised to only travel if necessary this morning due to black ice on roads across Donegal.
Gardaí say the Glenmaquin/Listillion junction on the N13 is in a particularly dangerous state.
Donegal County Council has also advised that the Curraghamone to Drumboe Road is closed.
Drivers are being asked to postpone any trips until later in the day when road conditions improve.
