Police are appealing for witnesses after a man fell from a motorway bridge at Leyland.
Enquiries are now underway to identify the man, believed to have been in his early 20s after police were called to the incident at junction 28 of the M6.
At around 11.30pm on Saturday the man had been stood on the wrong side of the footbridge when he fell into the carriageway.
Four vehicles swerved to avoid him but a fifth vehicle collided with the man as he lay in lane one of the carriageway.
The driver failed to stop or report the incident.
Sergeant Dave Hogarth from the Force Road Policing Unit said: “This is a tragic incident in which a young man has lost his life and we are doing all we can to identify his next of kin and establish the circumstances of exactly what happened.
“The vehicle that collided with man is described as a dark coloured saloon and I would appeal directly to the driver of that car, or anybody that witnessed this collision to contact Lancashire Police on 101.”
The southbound carriageway was closed for six hours between junctions 27 and 28 for a scene investigation to be carried out.
