A mum is fighting for life in hospital after a horror crash that killed her family in Queensland's Western Downs.
The woman in her 40s, was the sole survivor of the crash after her two children aged 9 and 15 died at the roadside along with their father, aged in his 50s.
The family were travelling in a sedan along Dalby Jandowae Road in Jimbour East, near Dalby, when it was rear-ended by a Land Cruiser ute.
The woman suffered chest and abdominal injuries and was airlifted to Dalby Hospital, where she remains in critical condition today.
The driver of the ute was taken to hospital with non-life-threatening injuries.
The Forensic Crash Unit is investigating.
