UPDATE: Ipswich firefighters used inflatable airbags to free a Redbank Plains woman trapped beneath a car after she was accidentally run over by her father.
The 36-year-old woman had stepped in front of the family Ford Falcon to open a gate when the vehicle lurched forward, pinning her under the wheels.
Her father's foot had apparently slipped from the brake to the accelerator.
The 68-year-old was white with shock when he realised what had happened.
Ambulance officers took the woman to the Princess Alexandra Hospital, where she was described last night as being in a critical condition.
The accident took place about 8.30am yesterday, and neighbour Emily Downes said that when she had rushed to the scene, the woman was unconscious.
Ms Downes had been alerted by the screeching of tyres, followed by a scream.
She said the front right portion of the car was resting on the woman's body.
"There were tread marks on her back," she said.
"The worst part was that, even though we had a jack, everyone was too afraid to move the vehicle off her because it risked making her injuries worse.
"I made an emergency call about 10 to 15 minutes before police, ambulance and fire rescue arrived.
"It felt like the longest wait of my life…I tried to console the family as we waited."
Ipswich police inspector Keith McDonald said ambulance officers had managed to revive the woman on-site.
Insp McDonald said she was taken to Princess Alexandra Hospital where she was in a critical condition.
"There have been many instances where accidents have occurred due to drivers putting their foot on the wrong pedal," he said.
"In this case though the outcome has seen a particularly tragic consequence."
Insp McDonald said the forensic crash unit was investigating the incident.
