A 70-year-old woman was airlifted to hospital after a freak collision in Clyde on Sunday 2 December.
It is believed a Ford Territory containing two occupants, both children, was parked at a Yallambee Road address when it began to roll down the driveway about 8.30pm.
The vehicle then entered the roadway and struck an eastbound Mitsubishi Triton, causing it to flip onto its roof.
The 70-year-old woman, the driver and single occupant of the Mitsubishi, was trapped for some time before she was airlifted to hospital with serious injuries.
The two children, a four-year-old boy and a three-year-old girl, were not injured.
