The Mountain Road and the Sloc are closed due to bad weather conditions.
The Department of Infrastructure is currently working to assess and clear the roads but until further notice they remain shut.
On Facebook, the Isle of Man Constabulary says most other roads on the Island are clear or passable with care.
Officers are urging people to drive to the conditions and to stay safe.
