A crash involving two vehicles towing caravans has caused chaos on the Bruce Highway.
The accident happened at about 1.50pm today 40 kilometres north of Marlborough near the town of Ogmore.
A Queensland Ambulance Service spokeswoman told the Courier Mail that  paramedics were assessing a male and female couple in their 80s, and a male and female couple in their 70s.
She said the 80-year-old male was initially trapped in the vehicle but had since been freed. He suffered some chest injuries and is in a serious condition.
The RACQ Capricorn Helicopter Rescue helicopter will transport him to hospital.

The spokeswoman said the woman in her 80s was in a stable condition, and the couple in their 70s was already ‘out walking and talking’, with no mention of injuries.
The Courier Mail reports that a police spokeswoman said the caravan had rolled and was leaking fuel, with several police crews on scene.
The Queensland Fire and Emergency Services said no smoke or flames had been reported from the vehicles involved in the accident.
So happy all seem to be safe
I had a caravan overtake me on the New England Highway approaching Scone. When we got into Scone they were stopped at the side of the road and getting ready to go into a cafe as we were thinking about the same thing. The gentleman spoke to me and said I was a traffic hazard at 85k’s and hour. I just requested that when he rolled his van try not to bloke the road, as we intended to get to Tamworth for the night. I am driving an ISUZU Home built motorhome with a Trailor and Mazda twin cab on board. I will normally move over and give plenty of room to others passing, however he came up on us that quick I didn’t have time to give him the curtesy. An accident looking for a place to happen.
