A trailer flipped on Dunedin's southern motorway this morning but no one was injured in the crash at Lookout Point.
A Fire Service spokesman said the 4WD was towing a double axle trailer carrying lengths of wood and "jack-knifed" just before 10.30am today.
"It has gone off into a paddock but is slightly blocking one lane."
The crash happened opposite Lookout Point Fire Station, he said.
