Heavy snow across the country has caused chaos on the roads and brought some public transport to a standstill.
The severe winter weather put a halt to all bus services in London, along with dozens of trains, and some airport runways closed.
Snow ploughs and gritters were working to clear roads as much of the UK was covered in snow.
A spokesman for the Highways Agency said: "If your journey is not essential I would strongly advise you don't make it."
Many of the country's schools were forced to close, including 50 in Birmingham and the Black Country.
A service spokeswoman for West Midlands Ambulance Service NHS Trust said: "Winter is always a busy time for the trust and many of the patients we see are absolutely genuine and need our care.
"Unfortunately with icy conditions and snow showers set to continue, the trust is expecting an increase in 999 calls due to falls, slips and road traffic collisions."
Commuters in the south-east have been one of the worst affected and faced a long and miserable journey to work.
