TWO trucks and a car were upside-down on the road following a crash near Northam on Monday.
Two men were taken to hospital but neither had life threatening injuries.
A caller to Radio 6PR said the crash happened about 20 kilometres east of Northam on the Great Eastern Highway.
"Two trucks on the left-hand-side are upside-down... 100 metres further on there's a car upside-down that looks likes it had been on fire," he said.
"There were a number of people there assisting... guys with fire extinguishers, a few other trucks had pulled over and truckies were helping out."
RAC Rescue arrived at the scene near the intersection of Leeming Road in Grass Valley.
Northam Volunteer Fire and Rescue Service and Grass Valley Bush Fire Service firefighters also assisted.
WA Police asked drivers to avoid the area and take alternative routes along Jennapullin Road, Clydesdale Road and Watson Road.
