Shortly after 4 pm, the rescue service was alerted to a single accident on road 795 between Källmyren and Ullriksfors.
It turned out to be a bus that drove off the road at low speed.
No person should have been injured in the accident.
According to ÖP, the passengers in the bus have been stuck since then - and will do so for a while longer.
A replacement bus has been sent to the site.
