Police are appealing for witnesses following a serious traffic crash at Wongwallan this evening involving a truck and two cars, Queensland Police say.
Preliminary investigations indicate the truck was travelling along Tambourine-Oxenford Road around 5.30pm when it collided with two passing vehicles, pushing one of them off the road.
The truck, which was towing an excavator, then flipped onto its roof.
The driver of the truck, a man aged in his 20s, was transported to hospital with critical injuries.
The occupants of the two other vehicles involved were not seriously injured.
Tambourine-Oxenford Road remains closed at the intersection of Elevation Drive following the crash.
Police are appealing for anyone who may have dash cam vision of a white Isuzu truck with an excavator on a trailer travelling along Tambourine-Oxenford Road prior to the incident to come forward.
The Forensic Crash Unit is investigating.
