In Scotland, an estimated 70,000 children missed classes as severe weather led to the closure of more than 300 schools.
Areas of the north-east Lincolnshire also saw school closures amid five inches of snow, and north Yorkshire saw eight.
Several schools were also closed in Wales.
There were long delays on five motorways, including the M1 and M25,
because of broken-down vehicles and slippery road conditions.
Scores of motorists were caught in an estimated 10 mile tailback on
the southbound M11 between Cambridge and Stansted, Essex earlier on Wednesday evening, after an accident.
Last year, hundreds of drivers were trapped overnight on the same stretch of
road, after the Highways Agency failed to grit it properly.
This year, the agency said no major routes in England had had to be closed because of the weather.
But it warned drivers throughout the country not to make any journeys unless "absolutely necessary".
Spokesman John Murphy said: "We're advising drivers to check on conditions on
their routes before making their journeys.
"We've continued to grit and salt all major routes and we want to remind
drivers to take care and driver safely."

Generally, main line services ran normally, but the adverse weather was blamed
for delays on some services in the south-east.
One South Eastern train from Ramsgate in Kent to London's Victoria station
arrived about three hours late.
And in the morning, some sections of the Metropolitan, Jubilee, Piccadilly and Central
lines had no trains because of problems on the open air sections of the Tube system.
Services on the Metropolitan
lines were still not back to normal by mid-afternoon.
Forecasters warned of another bitterly cold and frosty night on Wednesday night into Thursday morning, with temperatures warming up on Friday and at the weekend.
