Jon Caudwell, from the Highways Agency, said they were doing their best to keep major roads in England clear but needed help from motorists who should "really seriously consider" whether they needed to go out.
He said he was surprised at the level of traffic on the roads, given the advice not to travel. He said in some areas abandoned vehicles and jack-knifed lorries had blocked access for gritters.
WEATHER AND TRAVEL INFO
BAA tweeted about Heathrow: "There are hundreds of staff who will work right through the night at Heathrow to make the airfield safe for flights tomorrow."
Helen Abel, a solicitor from East Finchley in north London, was stuck at Heathrow on a plane bound for Sri Lanka for almost 11 hours on Saturday. She and her friend are trying to get away for a two-week break over Christmas but on Saturday evening the airline confirmed the flight would not be leaving before Sunday.
Passengers were given a meal on board before being told they could leave the Sri Lankan Airlines plane and spend the night in the airport, or risk going home and not making it back for the flight departing on Sunday.
Speaking from the plane she told BBC News: "It's so frustrating, although obviously it's not the airline's fault. The toilets have become pretty interesting though… there are better places to spend 10 hours."
Another passenger, charity worker Stuart Coles, spent five hours sitting on a Virgin plane from Miami that had landed at Heathrow but could not get to its stand as it had not been cleared of ice and snow.
"There were a lot of Americans and Canadians on the plane who couldn't understand why so little snow had brought everything to a halt," he said.
