A number of cars have left the motorway, including several vehicles around Junction 14, the Ardee exit.
A car also left the road in the Termonfeckin area.
There were four minor collisions on the M9 motorway this morning and while there were no injuries in any of the incidents, Thomastown Gardaí are warning that the route, both north and south bound, is still “treacherous”.
They’re asking all drivers to only make essential journeys and to slow down on the motorway in particular.
There have also been power cuts across the country in the wake of some heavy snow falls and high winds.
