They were rushed to the hospital by ambulance. Police were called to the scene just after 11 pm.
“One individual sustained serious, but not life-threatening, injuries. The other four suffered mild injuries,” Sven Matsol of the Dalarna police told TT.
The accident occurred when a car with three passengers attempted to turn onto the highway from a side road.
The driver, a 21-year-old man who was the most seriously injured, didn’t see the other car coming. There were two passengers in the second vehicle.
