An elderly male driver has died and a female passenger is fighting for her life after a collision with a truck in Queensland's Scenic Rim.
The Ipswich man, 75, died at the scene when the two vehicles collided on the Cunningham Highway near the intersection with Boonah Fassifern Road.
His passenger, 68, sustained serious injuries and was airlifted to Ipswich Hospital in a critical condition.
The male truck driver, 42, was not seriously injured in the crash, which has forced the highway to be closed and diversions put in place.
The Forensic Crash Unit is investigating.
