Yellow weather warning remains in place
The Mountain Road is currently closed due to snow and ice.
Police say the route will remain closed until after the morning rush hour, when it will be reassessed.
The Creg-ny-Baa Back Road and Begoade Roads are also closed.
Driving conditions are also being described as difficult in Foxdale, while the Ballamodha Straight had to close for a time after vehicles got stuck in snow there, but that road has now been able to reopen.
Officers confirmed gritters are on their way to the affected areas.
