The accident occurred at 07 o'clock in the morning, in the direction of Uppsala. None of the drivers should have sustained serious injuries, but one person was taken to hospital for care.
- Everyone could get out of the cars themselves, but a person should have suffered minor injuries, says Jarmo Carlsten, commanding officer at the Stockholm Fire Defense Association.
The car fire, which is described as heavy, was extinguished at 08 o'clock.
- We don't know why the car started to burn.
The accident creates very powerful car queues on the E4, which is expected to last as the cars are driven from the site.
