A driver had to be cut free from his car after a collision with an ambulance on an emergency call.
Police were called to the A644 Huddersfield Road at Scout Hill, Dewsbury , just after 9am on Sunday.
A spokesman for West Yorkshire Police said an ambulance on a 999 call was involved in a collision with a silver Toyota Yaris just under a bridge which takes the Spen Valley Greenway across the main road.
The spokesman said the ambulance was heading towards Dewsbury when it was in collision with the Yaris, which was thought to be doing a U-turn in the road.
The driver of the Yaris was complaining of back pain and firefighters were called to cut the roof off the car to lift the casualty out.
The driver was taken to Pinderfields Hospital at Wakefield. It is believed no-one in the ambulance was hurt.
Police partially closed the road while the vehicles were recovered causing some delays.
