A lorry driver has died after his vehicle left a trunk road in severe wintry conditions.
The incident on the A160 in north Lincolnshire happened as police across the north of England and Scotland warned motorists to take extra care due to sleet and snow.
Humberside Police said the white Scania lorry, which was fully loaded with meat, left the westbound carriageway of the road in South Killingholme at about 4.14am.
A spokeswoman said road conditions in the area were quite poor at the time due to cold weather and hailstones. The driver has not been named but is believed to be from the North West. He was pronounced dead at the scene.
The Met Office has issued severe weather warnings for most of Scotland as well as Northern Ireland and parts of northern England. They warn of sleet and snow showers and ice on untreated surfaces.
Snow and ice had already brought disruption to Scottish roads as the country faced its first bout of wintry weather. A fleet of 130 gritters were out overnight to treat roads and 3,000 tonnes of salt were used.
But the M74 in South Lanarkshire was down to one lane southbound after an HGV jack-knifed. The A74 in Dumfries and Galloway was also reduced to one lane when another lorry jack-knifed, while motorists were warned of black ice on the A9 between Plean and Falkirk. The A809 in Stirling was described as "very icy", as was the A905 in the Throsk area.
Stornoway airport was closed leading to delays on flights to and from Glasgow, Edinburgh, Inverness, Benbecula and Aberdeen. It was expected to reopen later. Edinburgh and Glasgow airports were operating normally.
Transport Minister Keith Brown said: "We've already seen some wintry weather across much of Scotland and, while it is not as severe as this time last year, we cannot afford to be complacent."
Andy Ratcliffe, a forecaster with MeteoGroup, the weather forecasting arm of the Press Association, said: "We will see more wintry showers with more snow over high ground in western areas. Northern England will see wintry showers but it will not be as badly affected as Scotland."
