Freezing temperatures and snowfall continued across parts of the UK on Wednesday morning after weather warnings covered all four nations.
Yellow warnings for ice and snow were prompted by the first snowfall of the season, which caused more than 200 schools to close on Tuesday. New warnings were announced for parts of the UK going into Thursday and the weekend.
Icy conditions led to warnings vehicles could be stranded, power cuts may occur and rural areas could be cut off.
National Rail advised passengers to check their journey before travelling.
