Cars have been brought to a standstill on the A30 in Cornwall due to heavy snowfall.
Around 100 vehicles are believed to be stuck on the carriageway at Temple, according to Devon and Cornwall Police.
Further disruption has also been reported between Camborne West in Camborne and Carminow Cross in Bodmin, as well as delays in Wadebridge and Padstow.
Motorists stuck in the snow have been seen exiting their vehicles, despite police advice to stay inside at all times.
Heavy snow showers swept across the county this afternoon, forcing several schools to close early.
The Met Office had predicted snow in the far east of Cornwall but many were taken by surprise after the white stuff feel thick and fast.
Andrea Child, who has been stuck in a car on the A30 for more than two hours, told ITV News West Country: "There are snow ploughs about one mile ahead trying to clear the roads in both directions.
"There is a lot of people in their cars that can’t go anywhere or have run out of petrol.
"We have been here for almost two hours and not moving and I am not really sure what is happening as cars cannot drive in this snow and it’s still coming down. It’s almost getting dark."
