The Met Office has issued yellow warnings for icy patches and snow covering swathes of the eastern coast of England.
Police forces across the country issued warnings to drivers to beware of icy roads.
Drivers became trapped on the A171 near Whitby in North Yorkshire, after up to three inches of snow blocked the road.

Farmers and council workers on snow ploughs attempted to help commuters to dig their cars out of the snow while police officers offered assistance.
Many were forced to abandon their vehicles on the gridlocked road while they waited in the icy conditions.

The double-decker bus, which was travelling to Middlesbrough, was amongst cars, trucks and tractors stuck on the road during rush hour.
An onlooker said: "It's completely gridlocked on the bank. A wagon couldn't get up and everything came to a stand still. The snow just came bouncing down about 2-3 inches deep."
The weather warning for the eastern UK said: "Wintry showers will bring an additional hazard and may lead to 2cm to 5cm of snow accumulating on ground above 100m, primarily over northern Scotland and north-east England."
