CRASH investigators are examining an early morning accident on the M1 Motorway that has left a teenager in critical condition.
Police said an 18-year-old man was critically injured after he stepped from his own rolled car and was struck by a second vehicle in the early hours of Tuesday.
His Nissan X-Trail was heading north about 2.30am when the driver lost control about 300 metres north of the Freemans Drive overpass.
The car landed on its roof and the driver pulled himself from the vehicle.
A Mercedes van heading north struck the man as he was standing on the road a short time later, police said.
The man, 18, was taken to the John Hunter Hospital.
The Mercedes’ driver, who escaped injury, was taken to Wyong hospital for mandatory blood and urine tests.
Lake Macquarie police and the Newcastle Crash Investigation Unit are conducting a full investigation.
One of two lanes on the M1 was closed northbound at the Cessnock turnoff shortly after 6.30am.
That allowed vehicles to pass through a single lane and the road’s shoulder, lifting an earlier diversion that ran on Freemans Drive before joining Palmers Road to link back to the M1.
Northbound lanes re-opened about 9am after lengthy delays, including queues stretching about three kilometres, during the morning.
No delays were reported for southbound drivers.
Anyone with information about the crash is urged to call Crime Stoppers on 1800 333 000.
