The Met Office has issued fresh yellow weather warnings across the UK, with ice alerts covering much of southern England, the Midlands and eastern Wales.
Several other warnings for snow and ice remain in force across Britain, as Arctic conditions continue to grip the nation.
Forecasters have warned that vehicles could become stranded, power cuts may occur and rural communities risk being cut off as some places face being covered with 20cm of snow.
The warnings come as temperatures plunged to -11.2C in Braemar, Aberdeenshire, marking one of the coldest November days on record.

Heavy snowfall was widely reported on Tuesday, with 12cm of lying snow recorded at Watnall, Nottinghamshire, as an Arctic airmass influenced the UK's weather. More than 200 schools were forced to close across the country due to the severe conditions.
Thousands of train passengers faced disruption, with services cancelled and delayed, particularly across northern England. In Aberdeenshire, a Stagecoach bus toppled onto its side with a passenger on board in icy conditions.
The Met Office warned that snow showers developing overnight could be heavy at times and accompanied by lightning in some areas.
Met Office spokesman Stephen Dixon said: "We've had a fairly mild November so far. So it'll feel like that first taste of winter for many with that snow and ice risk layered on top" He added that while the highest snow accumulations would be seen in Scotland's mountains, with up to 20cm possible, even small amounts could cause problems..
