Hunter Valley police are investigating after a fatal accident at Mount Thorley.
At about 8.40am on Wednesday emergency services were called to Putty Road between Broke Road and Jerrys Plains Road to reports of two cars and a truck colliding.
Paramedics treated the 19-year-old female driver of one of the vehicles, however, she sadly died at the scene.
The 57-year-old truck driver and the 45-year-old driver and two passengers of the other car – all males – were uninjured.
Police have confirmed both drivers were taken to Singleton Hospital for mandatory testing
The incident forced the closure of Putty Road in both directions for several hours, but it has since re-opened to traffic under alternating stop-slow conditions.
A crime scene has been established which is being examined by specialist forensic officers and a report will be prepared for the information of the coroner.
Authorities are calling for witnesses or anyone with dashcam footage to contact Singleton Police Station or Crime Stoppers.
