The Council's Roads Service is aware of an oil spill on the A970 road and drivers are asked to take care while driving south of Lerwick.
The oil spill appears to affect the road from the north of Sandwick to approximately Gulberwick - a distance of approximately eight miles. The origin of the oil spill is unknown but the road surface is slippy and hazardous in many places.
Roads staff have placed warning signs at various points along the road and deposited sand across the road surface at junctions and bends.
With low cloud and reduced visibility across many parts of Shetland today too, road users are asked to make sure they use dipped main beam headlights and rear fog lights wherever necessary.
