“One person is seriously injured and twelve suffered minor injuries,” said Sahlgrenska University Hospital spokesperson Robert Sjölund to the TT news agency.
The one seriously injured passenger is in his twenties.
The bus drove off of Oscarsleden just past the Älvsborg bridge traveling toward the Gothenburg city centre.
Road conditions were slippery at the scene of the accident.
“But we don’t know yet if that was the cause of the accident,” said police spokesperson Stefan Gustafsson.
The road will be closed for several hours, according to emergency crews working to clear the scene.
