Commuters are facing another night of travel misery as heavy snow has left drivers stranded on roads in the south of England as Britain is gripped by a freezing cold snap.
A weather warning for snow is in place affecting parts of southern England, which is set to move southwards over the course of the evening.
Drivers have been told to avoid the M3, with the motorway closed between junctions 6 and 7 near Basingstoke during a whiteout on Friday.
Hampshire Police urged motorists to "please stay in your cars" amid the adverse weather conditions.
Rail commuters living in south east London and Kent were told to "travel earlier or later to avoid the busiest trains" after Southeastern's winter weather timetable came into effect today.
It comes after travellers were hit by long delays and schools closed their doors today as February began with the coldest night for seven years.
Up to 14cm of snow caused havoc in the south west, forcing motorists to abandon their cars and seek shelter as traffic stood still.
Most flights were cancelled from a snow-covered Bristol Airport on Friday, but normal service is expected on Saturday.
Flight disruption at airports in Cardiff and Bristol left queues of rugby fans facing a race to get to Paris ahead of Friday evening's France vs Wales Six Nations opener.
Salt-spreaders covered 80,000 miles of England's motorways and major A roads through the night to keep traffic moving, Highways England said.
More snow is forecast going into the weekend, and though it is unlikely to be as heavy, there is a danger of untreated, treacherous ice covering paths and roads.
And temperatures this weekend could drop even lower than the blisteringly cold -15.4C experienced during the latest Arctic snap across Britain.
On Thursday night the temperature hit the sub-zero figure in the Scottish highlands, the lowest recorded since 2012.
A fresh yellow warning for snow and ice covering large areas of the UK took effect from noon on Friday until the same time on Saturday.
It covers northern Scotland, most of Northern Ireland, the eastern coast of England and the west coast of Wales.
A separate warning for ice is in place for the southern counties between 1pm on Friday and 11am on Saturday.
Conditions will be largely bright and cold through Saturday but a widespread hard frost and freezing fog are forecast for the early hours of Sunday.
Met Office forecaster Bonnie Diamond said: “Saturday could threaten the coldest night of the year so far.”
This again would be in “very rural Scotland”, she added.
Expanding upon the weekend, Ms Diamond said the temperatures across the board are to stay low while “wintry showers” are also possible.
However, crisp winter sunshine is set to shine down in many areas.
On Saturday, she said: “Another cold day but there will be plenty of winter sunshine for many.”
She added the snow will not be as widespread but there will still be “a few wintry showers of snow”.
Sunday will be largely “dry and bright” throughout the day but showers later in the day could take a turn.
This rain travelling from the west could turn into snow, although more places will likely see sleet or hail.
The areas most likely to be affected by snow are coastlines in the north and to the east, though as rain comes in from the west this could see elsewhere impacted.
New weather warnings are in place for parts of Scotland and the north west of England, which will continue in to Monday.
Throughout the days, temperatures are expected to sit around 2C to 4C, but overnight across the weekend most places will be sub-zero.
For London, there is a slim chance of wintry showers on Saturday, though the frosty downpours are not likely to spread strongly inland.
Snow beating down across Britain has already led to chaos on roads and at airports shut across the nation.
Highgate Hill in London saw major disruption with vehicles unable to get up the incline due to the coating across the road.
Buses were seen along the route stuck due to losing grip on the carriageway and unable to move.
Transport for London said that certain bus journeys were being cut short due to the large red wagons becoming stuck.
Elsewhere on Friday, a landslip at a village in Cornwall blocked off vehicle access to around 30 homes and kept other cars trapped inside a cul-de-sac.
Around 1,000 tonnes of hillside collapsed on to the narrow Scrations Lane, in the village of Lostwithiel, but no-one was injured and no property damaged, Cornwall Council said.
As issues arose overnight, more than 100 people stuck on the A30 in Cornwall took refuge in a pub along the stretch.
They sought shelter at the Jamaica Inn on Bodmin Moor and the pub's 25-year-old general manager, Sammy Wheeler, said: "A lot of people have abandoned their cars. Some of them have walked a good three, four or five miles.
"People were fed up of being in a cold car and they were running out of fuel."
Highways England told the drivers to pick up their vehicles "as soon as possible".
Councillor Geoff Brown, who handles transport at Cornwall Council, said "the actions of a few impacted on many" after abandoned cars blocked emergency services, delaying the clear-up.
Authorities asked motorists to completely clear their vehicles of snow and Wiltshire and Thames Valley police forces advised drivers to travel only if absolutely necessary.
One driver claimed he "could see perfectly well" after his car, with its side windows completely encased in snow, was stopped in High Wycombe, police added.
Thousands of schoolchildren had a snow day on Friday, with hundreds of schools across the country closed their doors.
They included more than half of Bristol's schools, more than 300 in Buckinghamshire, more than 150 in Cornwall and scores across Oxfordshire.
On the rail network, passengers were urged to check before they travel in case the conditions impact services and some Eurostar services were cancelled on Friday.
Transport for London also advised passengers to check their service status before setting off.
The Met Office said a low of minus 15.4C (4.3F) was recorded just before midnight on Thursday at Braemar in the Scottish Highlands.
Had it fallen more than 0.2C (0.4F) lower it would have surpassed the low of minus 15.6C (3.92F) set in 2012.
