Police are investigating a fatal traffic crash involving a four-wheel-drive and a cattle truck that occurred at Muckadilla last night.
Preliminary information suggests the four-wheel drive was travelling westbound on the Warrego Highway when it collided with a road train carrying more than 150 head of cattle at 10.50pm.
The prime mover rolled, causing the vehicle's cabin and trailers to catch fire.
The driver and sole occupant of the four-wheel-drive, a 39-year-old Roma man, suffered extensive injuries from the crash and was declared deceased at the scene.
The 47-year-old male driver of the road train was not seriously injured.
A number of cattle were killed in the collision, with some also being euthanized due to injury.
The Warrego Highway will remain under traffic control this morning while the scene is cleared.
The Forensic Crash Unit is investigating.
