Country Patrol Group Inspector Sharee Cumming said investigations into the crash were continuing.

"The crash is still under investigation," Insp. Cumming said.

"The sedan has veered onto the wrong side of the road into the path of the oncoming truck.

"The cause of the vehicle veering onto the wrong side of the road is still subject to investigation."

Several witness statements were taken from nearby residents and passing motorists at the scene.

Queensland Fire and Emergency Services Inspector Peter Bradow said multiple fire units were deployed to the crash scene with initial reports the truck was on fire which spread to a nearby paddock.

It took firefighters about 30 minutes to bring the grassfire under control.

"The fire itself, from (QFES) perspective, was probably caused by heat on the exhaust," Insp. Bradow said.

"All crews attending did a very good job with a couple of priorities in that they had an extraction from the vehicle as well.

"Once a truck is on fire, you've got a large volume of fuel in the tanks and once the fire gets established, it normally melts the aluminium and contributes to the fire."

The Forensic Crash Unit investigation is continuing.

UPDATE 12PM: A woman has been taken to hospital with suspected spinal injuries after a shocking collision between a car and truck at Meringandan.

Damage to the dump truck carting heavy rock is believed to have sparked a large fast-moving grassfire on one side of Meringandan Shirley Rd.

It took firefighters 30 minutes to bring the fire under control.

Meanwhile just metres away on the opposite side of the road, firefighters and paramedics worked to free a woman, believed to be in her late 40s or early 50s, from a badly damaged sedan.

Queensland Fire and Emergency Services Inspector Peter Bradow said firefighters were forced to cut away part of the car to free the woman pinned inside by a collapsed dashboard and steering wheel.

"She has suspected spinal injuries and will be transported to Darling Downs Health Services," he said.

"She was entrapped by the dash and steering wheel."

Multiple fire crews were deployed to battle the grass fire which engulfed and surrounded the truck.

The truck driver escaped uninjured.

'The truck fire at this stage is under investigation and we believe it was a result of the impact," Insp. Bradow said.

He commended the actions of neighbours who were first on the scene and spoke with the woman trapped in the sedan.

"The neighbours around the place certainly provided some emotional support until (emergency services) arrived," he said.

Investigations into the cause of the crash are continuing.
