The collision occurred just before 10.20am on the north-bound carriageway between Topcliffe and Thirsk near The Grange turn-off.
It involved a motorcyclist riding a black Kawasaki and a white Ford pick-up which was towing a horsebox.

The motorcycle came to rest in the central reservation as a result of the collision.
The motorcyclist, a man in his fifties from the County Durham area, sustained serious injuries as a result of the collision and was airlifted to James Cook Hospital in Middlesbrough where he remains in a critical condition.
The driver of the pickup, a man in his thirties from Doncaster, was arrested in connection with the crash. He is currently in police custody.
The north-bound carriageway was fully closed, while the south-bound carriageway was partially closed. The road was reopened at 2.45pm this afternoon.
