Gritters were called in to make a head start on tackling impassable roads across Dorset, as icy temperatures grip the county.
Highways workers were scheduled to pre-treat the main network and rural routes from the early hours of Boxing Day.
Teams were also on call to plough roads throughout the day, Dorset County Council said.
Much of the county is still covered in snow after it fell last week and temperatures plummeted overnight.
The council said its current salt stock stood at 5,300 tonnes but more deliveries were expected in January.
A further 2,500 tonnes of salt has been put on order over the following weeks.
"We are constantly monitoring the weather forecasts and will alter our plans accordingly," a council spokesman said.
"Motorists are advised to take extra care and not to travel unless absolutely necessary if conditions are severe."
The council added that in order to maintain its resilience, it was unable to respond to ad hoc requests for extra salting, unless requested by the emergency services.
Dorset County Council's gritting fleet has 26 vehicles which treats approximately 677 miles (1,089 km) of road.
