Heavy snowfall has seen motorists abandon their vehicles as Storm Eunice brings a barrage of weather fronts.
The named storm - the second to hit the UK in as many days after Dudley - has unleashed hurricane-like 100mph winds and intense wintry showers.
Drivers have been pictured in County Durham standing alongside their cars as they attempt to make the morning commute.
One young woman is seen alongside a Ford hatchback on a roundabout in Consett after struggling to deal with the conditions.
And another snap shows a man leaning into the same car - seemingly later in the morning - as other motorists attempt to manoeuvre round.
While vehicles are also seen struggling on a road in Paisley, Scotland, and Eastfield, North Lanarkshire.

Forecasters fear the cyclone could unleash a devastating sting jet, not seen in Britain for more than three decades.
The cyclone storm system is expected to bring hurricane winds of 100mph in parts of the UK as many Brits prepare to hunker down for the day.
The Met Office has issued two rare red warnings, only the 11th time this highest level has been implemented by the national weather agency.
Schools, business and transport have been locked down, with an array of other warnings to remain through the weekend.
The worst of the weather is forecast for South Wales and the south of England.
A sting jet is a rare system that sees an incredibly powerful, highly concentrated area of wind within a high-speed storm.
The worst of the damage caused in the Great Storm of October 1987 has been attributed to the phenomena - so named because its satellite photos resemble a scorpion's tail.
They are just 30 miles in width and last up to four hours in storms that pass across Europe.
The 100mph jets form when a stream of cold air is pulled down into a warmer system at the head of a storm, creating evaporation and accelerating air speeds.
Dr Ambrogio Volonté, of the University of Reading, described Eunice as a “bomb” cyclone, similar in structure to the 1987 storm.
Eunice is a type of cyclone where the cold front does not catch up with the warm front, creating a gap which can pull strong winds towards the ground - creating the sting jet.
Met Watch UK says Storm Eunice is “currently undergoing explosive cyclogenesis in the Atlantic and will likely have a Shapiro-Keyser cyclone structure as it arrives”, which means it has a greater chance of a sting jet.
Storm Eunice was forecast to last from 3am today, with strong winds then lasting through the weekend.
Major incidents have been declared across come cities and counties, with people advised not to travel unless essential.
Eunice comes on the back of Storm Dudley, which claimed one life and left thousands of people without power.
Meanwhile, travellers are being warned to check with their airline before making their way to an airport as a huge number of flights across the country have been cancelled.
In London City Airport, all flights have been cancelled and many have also been delayed or cancelled from Heathrow, Gatwick and Stansted.
London Mayor Sadiq Khan echoed TfL's advice to avoid non-essential travel in the capital.
He said: "I urge all Londoners to stay at home, do not take risks, and do not travel unless it is absolutely essential."
