The Met Office says more snow is on the way in Britain this weekend.
Blizzard conditions caused widespread disruption to travel across the country on Friday. Major roads and rail routes were shut, schools closed and planes at some airports were grounded.
The weather is the coldest for 20 years.
Both road bridges over the River Severn linking England and Wales were closed for much of the day because of ice falling from the overhead gantries.
The Highways Agency warns people should not travel unless they have to.
The Local Government Association said council reserves of grit to go on roads have been "massively depleted".
The Met Office forecasts further snow falls over the weekend and into next week, with weather warnings for icy conditions in place across much of Britain.
