A teenage girl remains in a serious condition in Westmead Children’s Hospital following a single vehicle crash south of Wattle Flat on Friday morning.
Police, paramedics, SES and other emergency services rushed to the scene just after 10.40am after reports a vehicle had hit a tree on Limekilns Road, three kilometres south of the small township.
Inspector Gerard Powell from Chifley Police District said the driver, an 18-year-old woman, lost control of the car on an unsealed piece of road.
Crash investigators are now looking to piece together how the accident occurred.
Emergency services received the first triple 000 call at 10.46am saying the car had hit a tree and four people were injured in the crash.
When paramedics arrived at the scene they found three of people suffering superficial injuries including suspected abdominal injuries.
However the fourth person, a 14-year-old girl, in the rear passenger seat of the sedan, which bore the brunt of the collision, was unconscious and suffering a large laceration to the head.
NSW Ambulance sent three crews to the crash, and dispatched the Bankstown based rescue helicopter, which landed at the scene and after paramedics stabilised the teenager flew her to Westmead Hospital where she remains in a serious condition.
The other three people in the car were treated at the scene by paramedics. Two of the three were then taken to Bathurst Base Hospital via road ambulance in a stable condition.
The driver underwent mandatory drug and alcohol testing.
Inspector Powell said the crash was a stark reminder for drivers to exercise caution and drive to conditions.
