The crash on Sunday which closed a road north of York for several hours involved an ambulance, police revealed today (Tuesday).
It happened near Sheriff Hutton and saw a white Ford Fiesta and the ambulance collide.
The driver of the car, a man in his 40s, sustained very serious injuries and currently remains in hospital, a North Yorkshire Police spokesperson said.

The ambulance was responding to another incident when the collision happened, at around 5.55pm on Moor Lane, near Lilling Lane and Rice Lane.
Investigators are asking anyone who saw either vehicle in the moments leading up to the collision, anyone with dashcam footage, or anyone who has any other information to contact North Yorkshire Police.
It’s the second serious collision involving an ambulance near York in a month.
On 22 April a man died after an HGV and ambulance collided on the A1079 Hull Road between Wilberfoss and Barmby Moor.
