A major traffic accident on Ring 3 in Oslo has caused significant disruptions.

The collision involved four vehicles, including two trucks, a garbage truck, and a car.

One person is seriously injured and has been taken to Ullevål Hospital, while another person with minor injuries is being checked at a local clinic.

The accident occurred when a car abruptly braked in the right lane, leading to a chain reaction crash.

As a result, Ring 3 was partially closed, causing long delays and affecting public transport, with some buses delayed by up to an hour.

Emergency services are on-site, working to clear the vehicles and manage the traffic.

Authorities advise drivers to seek alternative routes as the road may remain closed for some time.
