Police warn of extremely slippery roads in three Swedish counties as crashes are reported

"The police are receiving several calls about extremely slippery road conditions in several places," police region Mitt writes on its website.

"Drivers are therefore advised to reduce their speed and keep a safe distance from the vehicles in front."

In Vårdsätra, outside Uppsala, a passenger car has crashed into a shelter, UNT reports. In Hedesunda, in Gävle municipality, a truck has skidded on road 509 and is blocking the entire roadway, Gefle Dagblad reports.

Roads are also slippery in other parts of the country.

Between Skövde and Mariestad, for example, a milk truck has overturned, spilling milk across county road 2761, Expressen reports.

A truck driver says he lost control of his vehicle in the slippery conditions on Highway 52 outside Örebro and ended up in a ditch.

Outside Umeå, a bus carrying around 50 people and a truck have been involved in a minor sideswipe collision. Police say slippery roads were likely the cause.
