Police are appealing for the driver of a horsebox that was travelling on the M62 on Wednesday 28 December to come forward.
The vehicle officers want to trace is described as a blue coloured Ford Iveco horse box with the word "horses" written on the side in yellow or gold writing.
The vehicle was travelling west bound (the direction of Manchester) at around 4.15pm when it and a grey coloured Audi A1 were in collision. As a result of the collision the Audi went onto the hard shoulder where it was in collision with the barriers.
The driver required hospital treatment. The horsebox did not stop at the scene.
