At 01.25, the alarm was received about a triple collision with two cars and a truck at the A6 junction.
The four who were in one car were taken to hospital with unclear injuries.
They are said to have been conscious when rescue personnel arrived at the scene of the accident.
- The truck driver must be unharmed, but the man in the other car was pinned down.
Rescue personnel have now managed to free the person, but you must examine her injuries inside the car before you dare to move him, says Bo Gunnar, officer on duty.
The accident occurred in a southerly direction and the road has been closed.
- I assume that the traffic is up and running within 45 minutes, Gunnar said at 02.10.
How the collision took place is still unclear.
