A 52-year-old man has suffered critical head and leg injuries in a high speed crash at Thornton overnight.
Emergency services were called to Haussman Drive just after 8.00pm on Wednesday.
Police say a motorbike collided with the front of a Ford Courier being reversed into a driveway.
The rider was thrown from the motorbike on impact, with the bike continuing riderless for a short period before colliding with a traffic island.
The rider was taken to the John Hunter Hospital where he remains in a critical condition.
The 65-year-old driver of the Ford was arrested and taken to Maitland Hospital for mandatory testing.
Haussman Drive was closed for three hours while crash investigators examined the scene.
Investigations are continuing.
