Motorists will face another day of treacherous driving as snow and ice continues to bring hazardous conditions to roads.
Weather warnings have been issued by the Met Office for large swathes of the country, with up to 10cm of snow expected in some areas.
Yellow alerts cover all of Scotland, Northern Ireland and Wales, as well as south-east England, the Midlands, Yorkshire and Humber regions and the north-east.
Scotland saw lows of minus 8C overnight that brought widespread frost.
Icy patches are predicted just as widely, with the Met Office website warning drivers they could face “difficult” conditions.
A Met Office spokeswoman said: “We have warnings out in Scotland for some snow in the west and ice in the south, as well as in Northern Ireland, south-west England and into Wales.
“The East Coast will have ice warnings into East Anglia and Lincolnshire and the North East.
“Friday will see bands of cold and wintry showers moving southwards, with gale-force winds in places such as East Anglia and Kent.”
