The driver of a truck that rolled off State Highway 2 this morning will face charges of careless driving, Senior Sergeant Shannon Clifford has said.
The man sustained minor injuries and was not wearing a seat belt at the time of the crash, Mr Clifford said.
"As it went around the corner the load started to sway which has caused the whole unit to roll."
The truck also knocked over a power pole when it rolled, he said.
The highway was reduced to one lane for nearly five hours until the truck was pulled from the ditch and power lines were fixed.
