An investigation is underway after two people were seriously injured in a crash at Mount White early on Sunday, October 27.
Emergency services responded to reports at about 7.15am of a head-on crash between a utility and a sedan along the Old Pacific Hwy.
The driver and sole occupant of the sedan, a 27-year-old man, was trapped for approximately one hour until released by rescue personnel.
He was treated by NSW Ambulance paramedics at the scene before a medical team from Westpac Rescue Helicopter took over and flew him to Royal North Shore Hospital in a serious but stable condition.
The 45-year-old male driver of the utility was taken to Gosford Police Station, and later released pending further inquiries.
Two female passengers in the utility, one aged 19 and another in her 40s, suffered minor injuries.
A third female passenger, aged 19, was also airlifted to hospital in a serious but stable condition.
