Motorists are being urged to take extreme caution on secondary routes across the region due to low temperatures overnight.
In Mayo, there are several reports of black ice and icy stretches on secondary routes, particularly in the Claremorris hinterland.
Most national primary routes around the county are reportedly safe, but motorists are advised to take caution.
It takes long to stop in icy conditions, so slow down and keep further back from whoever’s in front of you.
There are no incidents reported so far this morning.
