The Forensic Crash Unit is appealing for witnesses following a traffic crash in Wacol in Brisbane’s south-west.
Initial investigations indicate at approximately 11.50am on Monday July 22, a white 2002 Toyota Hilux utility was travelling east along the Ipswich Motorway near Wacol Station Road when it struck a concrete barrier before veering across four lanes of traffic.
The vehicle then struck a grey Toyota Prado before crashing into the centre concrete barrier.
The driver of the Toyota Hilux, a 57-year-old Birkdale man, and passenger, a 65-year-old Inala man, were transported to Princess Alexandra Hospital in a critical condition.
The occupants of the Toyota Prado sustained non-life threatening injuries.
Witnesses, particularly anyone with dashcam vision or CCTV from the area at the time of the incident, are urged to come forward.
Investigations are ongoing.
