Acting Superintendent Henry Parsons from the Roads Policing Unit, said road conditions 'are not good'.
He said: "I would advise motorists to only use their cars if absolutely necessary and if you have to drive anywhere then I urge drivers to be slow in the snow.
“We had a very busy day yesterday with numerous crashes, fortunately most of which have been predominantly either 'damage only' or minor injury across the force area.
