UPDATE 5PM: A COUPLE in their 70s were lucky to escape relatively uninjured after their Ford Focus sedan, and the caravan it was towing, rolled on the Isis Hwy.
Bundaberg Patrol Group forensic crash investigator Senior Constable Timothy Lowth said police were still trying to determine what caused to male driver to lose control of his car.
"Over the course of about 100m it appears that he has tried to maintain some sort of control but this has failed and as a result his vehicle has overturned," he said.
"This time of the year there are a lot of caravans on the road and we ask both drivers and also other people to give them a wide berth to make sure it is safe for their passage and if you are driving a vehicle, know how to drive it."
The crash occurred about 9.45am Monday and Queensland Ambulance Service advanced care paramedic Grant Blair said the couple were travelling south when the crash occurred and left the car and caravan upside down in the middle of the highway.
"The woman was assisted from the vehicle post the accident and the gentleman required assistance from QFES with extraction," he said.
"Both the gentleman and the female have virtually no injuries at all, very lucky.
"Whenever you go to a roll over you always expect to find the worst, fortunately today they've both been very lucky and we'll transported them hospital for precautions."
Mr Blair said it was an unfortunate way to end the school holidays and long weekend.
"It's not a nice way to end the weekend, if you are travelling home, of course fatigue can set in quite quickly on long drives so always remember to stop, revive and survive," he said.
Queensland Fire and Emergency Services station officer Vicki Shailer said two crews were tasked to the crash and assisted in freeing the driver.
"It wasn't very tricky, we were able to open up all the doors and lift that person out onto the strether," she said.
"Being a 100km zone, single vehicle and rollover with a caravan, they've been very lucky today that there haven't been further injuries."
UPDATE 10.45AM: Two people were lucky to escape with minor injuries after their car towing a caravan rolled on the Isis Hwy a short time ago.
The couple, believed to be in their early 70s, were initially trapped in their silver vehicle after their car overturned as they were travelling southbound.
It is not yet known what led to the rollover.
The woman was able to exit the car unassisted, but emergency crews had to free the man, who was trapped upside down at one stage.
Crews are still working to clear the scene, where the car and caravan are still overturned in the middle of the road.
The road has been closed, but cars travelling in both directions are still able to pass slowly under the direction of emergency services on the scene.
UPDATE 10.12am: THE person trapped following car and caravan rollover on the Isis Hwy has now been released and is being tended to by ambulance crews.
EARLIER 10am: ONE person trapped, hanging upside down following a car and caravan rollover on the Isis Hwy.
Emergency crews are using jaws of life to release the trapped person.
The road has been closed.
More to come.
