How is the weather affecting your journey?
Severe weather overnight has caused major travel disruption, with more expected throughout the morning.
Amber and yellow snow and ice warnings are in place across vast swathes of the UK, with delays, road closures and stranded vehicles expected.
Trains and planes were also likely to be affected, with travellers urged to check the latest situation before setting off on their journeys.
Here are some of the latest reported issues:
Roads
Several roads across the country have been left impassable following heavy snowfall overnight, forcing police to close large sections of major routes.
In Yorkshire, the A61 has been shut between Harrogate and Skipton due to the conditions, while further north, in Durham, the A66 was closed between the A1M and A685.
The A1 in Durham was also closed between Scotch Corner and Catterick after a lorry jack-knifed.
Highways England said the A1 in Cambridgeshire had to be shut due to severe weather, between the A1M and A6121 at Tinwell.
