A two-vehicle crash at the Black Gaet around 9am this morning caused disruption to traffic during the rush hour.
Police attended the scene and said the two cars crashed due to a heavy hail shower, which made the road “very treacherous”. No-one was hurt in the incident.
The cars partially blocked the road but police said traffic could still flow, in a limited capacity, by using the grass verge.
SIC road inspectors also went to the accident to inspect the condition of the road, which was gritted shortly afterwards.
Police have again issued a plea for motorists to reduce their speed in freezing conditions.
This incident follows one on Tuesday morning on the West Side when three vehicles, two vans and a council lorry, crashed on black ice.
A spokesman said: “Road conditions in the Shetland area have been wintery and unpredictable resulting in a number of road accidents. Fortunately no-one has been hurt as a result of these incidents.
“These conditions are set to continue over the next few days and police would like to appeal to members of the public to drive with increased caution during this time. Generally reduce your speed. When travelling through bends in the road do not brake but ensure that you have reduced your speed sufficiently before entering it.
“All tyres should have sufficient tread on them and you may wish to consider fitting ‘winter tyres’ for increased grip.”
