The officer sitting in the driver’s seat suffered abdominal injuries and had to be cut from wreckage following the smash, on a south-bound exit of the Pacific Motorway near Helensvale.
Police say the marked vehicle, containing the 48 and 50-year-old policemen, was parked on the side of the motorway when hit about 11.25am.
The truck driver, 26, was also taken to Gold Coast University Hospital with minor injuries.
Images from the scene showed a truck on its side and the back of the police car severely crushed.
Witness Joyce Zhi Xia posted photos to Facebook and described “sudden smoke up in the air” before the truck rolled.
“So scared and terrified. All just happened in seconds,” she wrote.
The incident caused heavy delays on the M1, Queensland’s busiest motorway, with traffic banked up for kilometres hours after the crash.
All three injured men were in a stable condition after the condition of the officer who had been trapped was downgraded on arrival at hospital, Queensland Ambulance operations supervisor Pat Berry said.
A TRAPPED police officer had to be cut from his wrecked car after a terrible smash with a truck on the M1.
The M1 was in gridlock after a truck reportedly rolled on to the police car in the southbound lanes just after 11am.
It is understood two police officers were sitting in the car parked by the side of the M1 when the truck veered out of its lane, clipping the police car on the side and crushing the police car on to the side barrier.
The collision caused the truck to tip on to its side. It then slid 70m down the road.
A witness reported seeing an officer freed from his vehicle by emergency service personnel using the ‘jaws of life’.
There are now some lanes closed between exits 62 and 66.
Traffic is rapidly building and is banked up several kilometres back to the Oxenford exit.
Traffic in the northern lanes is also slowing with reports it has banked up back to Gaven.
Queensland Ambulance operations supervisor Pat Berry said all three men involved have been taken to Gold Coast University Hospital.
He said they are in a stable condition and however the police officer behind the wheel of the police car has injuries to his collarbone and abdomen.
“The driver the police vehicle has some abdominal and clavicle injuries,” Mr Berry said.
“We can confirm all three patients are in a stable condition.”
Mr Berry advised motorists to avoid the area with congestion especially bad from Helensvale South to the Smith Street off ramp.
“There is still congestion in both directions — I expect the incident to be cleared at 2pm,” he said.
Meanwhile lanes are blocked in both directions on Nerang-Murwillumbah Rd at Advancetown after a head-on collision about 11.40am.
Queensland Ambulance have confirmed there were no serious injuries, but long delays are being experienced in the area.
Police and tow truck drivers are working to clear the scene.
