A man has been taken to hospital after a crash involving four cars at Adamstown overnight.

Residents of Gosford Road were woken by a loud bang just after 11.30pm on Wednesday, to find a Holden Commodore had clipped two cars and crashed heavily into a third.

Police, fire and ambulance paramedics arrived to find the 59-year-old male driver trapped.

He was extricated on a back board through the front passenger door and placed on a stretcher before being taken to the John Hunter Hospital in a stable condition with a head injury.

Police are investigating whether alcohol was a factor in the crash.

Meanwhile, the Hunter’s Westpac Rescue Helicopter was called to a car roll over on the New England Highway at Murulla north of Wingen just after 2.30am on Thursday.

The 30-year-old male driver was airlifted to the John Hunter Hospital.

A 30-year-old female passenger suffered non-life threatening injuries, while a 20-year-old female was not injured.
