The accident occurred at 07 o'clock.
According to the rescue service, the person was awake and talkable when an ambulance arrived at the scene.
It is unclear exactly how the accident happened.
The truck is now halfway down the ditch near the bus stop which is located at the petrol station at Hyltena.
- It is presumably the slipperiness that caused the accident, says Fredrik Malm, the rescue service's task leader at the scene.
According to the police, road conditions have been slippery in several places in the county in the morning.
Among other things, an accident occurred between two cars near Landsbro at 07.45.
There are no reports of serious injuries.
