RCMP say a southbound vehicle appears to have lost control and hit the side of a semi-truck it was attempting to pass.
The semi driver went into the ditch to avoid the collision, but the truck ened up rolling onto its side, spilling a load of logs.
The incident happened 12 kilometres north of Prince Albert.
No injuries were reported.
Alcohol is not believed to be a factor and police say road conditions were good at the time.
