A motorist, aged 51, has sustained life-changing injuries in a motorway collision on the M18.
Police are now trying to trace another driver who they believe may hold vital information regarding the collision on the M18 in Doncaster on Monday.
The incident happened around 12.25pm when a blue Mitsubishi Shogun was travelling northbound on the motorway, approaching junction six near Thorne.
The vehicle collided with the parapet of a metal bridge.
The Shogun’s 51-year-old driver, from Grimsby, was taken to hospital with injuries that have been described by medics as ‘life-changing’.
A South Yorkshire Police spokesman said it is vital they trace witnesses to help piece together exactly what happened.
The police spokesman added: “Police now want to speak to the driver of a dark estate-style car, who it is thought could have witnessed the collision.”
The incident caused travel chaos on the roads, as traffic came to a standstill for several hours following the collision that resulted in a lane of the motorway being closed.
Anyone who witnessed the collision is asked to get in touch with South Yorkshire Police on 101, quoting incident number 441 of February 10, 2014.
