Drivers in Devon are warned to avoid overnight travel
Drivers in Devon have been warned to avoid overnight travel "unless absolutely essential" as freezing temperatures continue.
Devon County Council said road surface temperatures in the county were expected to fall to -8C (18F), making driving conditions hazardous.
Road gritters have salted about 2,000 miles of the county's roads.
But the council said motorists should be extremely careful, even on roads which have been treated.
Councillor Stuart Hughes, Devon County Council's cabinet member for highways and transportation, said: "Any ice that is around is mainly from the thaw and refreezing that we have experienced.
"Everyone has to be prepared for another heavy frost and the possibility of mist and fog which could make conditions even more hazardous."
