The truck, which was towing an excavator, then flipped onto its roof.
The driver, a man aged in his 20s, was treated at the scene for head, neck and leg injuries before being rushed to Gold Coast University Hospital in a stable condition.
The three occupants of the other two vehicles suffered minor injuries and were also taken to Gold Coast University Hospital.
Police are now 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.
