Buses have been cancelled in Sörmland, and police in Östergötland are warning drivers to take care on the slippery roads, news agency TT reports.
Police in Halland, Kronoberg and Jönköping counties in the south have reported multiple cases of drivers sliding off the roads and into ditches. One man was seriously injured when a car carrying six people skidded off the road and ended up on its roof on Öland.
Hospitals are also busy dealing with broken bones and fractures, as pedestrians fall over on the icy pavements. The University Hospital in Örebro has had to treat 84 patients with different types of fractures over the last 24 hours, "the worst ever", according to the head of the fracture department.
