People are being urged to stay at home and to only travel if absolutely necessary with up to 8in (20cm) of snow on the ground in Berkshire.
Temperatures remain freezing across the county and roads have turned icy.
Thames Valley Police urged motorists to take care because roads were "still unsafe due to freezing conditions".
On Sunday crews were called to Boulters Island, near Maidenhead, where a man suffered injuries when a large branch fell on him.
He was treated in hospital for a broken bone.
Police said drivers should not abandon vehicles, especially where they might block emergency crews and major roads.
"If they do, the vehicles may have to be removed and it will be the driver's responsibility to pay for the cost of recovering them," a police spokesperson said.
Residents have been advised to check their council websites for the latest information on which roads are being gritted.
Police also said people should check on elderly or vulnerable neighbours.
Reading Borough Council said there might be some delays to bin collections next week due to icy roads but advised residents to put their bins out as normal.
