An elderly woman was airlifted to the Sunshine Coast University Hospital in a serious condition about 1:00pm on Monday after a crash near Woolooga.
A police spokesperson said emergency services were despatched to the corner of Southern Road and the Wide Bay Highway near Turpentine Creek about noon on Monday.
They found a car and hay truck on the site, with the female car driver still trapped in the vehicle.
Hydraulic cutters were used to free her, which was accomplished about 1:00pm.
The woman, aged in her 70s, was then airlifted to hospital by the RACQ LifeFlight helicopter which landed nearby.
The driver of the hay truck was uninjured, but the woman is believed to have suffered serious injuries to her chest and both legs.
LifeFlight critical care doctor Joakim Johansson said it was lucky she wasn’t killed.
“Her airbags were deployed and the vehicle was very heavily impacted,” he said.
The highway was reopened to traffic soon afterwards.
Police investigations into the cause of the incident are continuing.
