Motorists face a further period of hazardous driving conditions as sub-zero temperatures continue to leave many of Britain's roads icy.
Drivers have been warned of slippery conditions on the roads, with severe "yellow" weather warnings in place across much of England, including London, the South East, the East, the South West, the Midlands, Yorkshire and Humber and the North East.
And things could get worse, with snow forecast in the next three days - East Anglia and the East Midlands could get between 3-6cm of snow, with southern areas also expected to have a sprinkling.
Drivers should ensure they have essentials such asbreakdown cover , blankets, snacks and warm clothing in case they are caught up in travel chaos as the big freeze continues.
And even if there is a thaw, experts warned that ice will remain a problem for the coming days.
Nick Prebble, forecaster for MeteoGroup, said: "Road temperatures in winter can be a couple of degrees centigrade lower than the air temperature, so there's still a risk of ice on the roads over the weekend and potentially into next week."
