A 58-TONNE logging truck rolled on a notorious corner the Ballarat-Colac Road near Enfield just after 8am today.
The truck was travelling at 90km/h in a 100km/h zone with 38 tonnes of logs on the trailer before becoming caught in the ditch on the side of the road and rolling.
Driver Chris Mahoney was lucky to only receive bruising from the seatbelt in the incident.
"I just came around the bend and in the corner of my eye I could see the trailer wave behind the truck," he said.
"Then the cabin of the truck just went over."
Three police units are at the scene and diverting traffic along the side of the road.
Rokewood Senior Constable Bryan Vincent said inquiries were being made into the circumstances of the rollover.
