A driver died when he got out of his car in the middle lane of a motorway and was struck by a number of vehicles.
It happened on the southbound carriageway of the M18 near Doncaster shortly after 7am on Friday.
The 53-year-old, from Gilberdyke, Humberside, was believed to have got out of his blue Ford Focus after it stopped in the middle lane between junction three and two.
A 26-year-old in a green Ford Transit tried to avoid a collision but clipped the Focus, then hit the man, South Yorkshire Police said.
Two lorries collided with the van, then one of the trucks hit the man.
A South Yorkshire Police spokesman said the 53-year-old suffered "fatal injuries" and five people in other vehicles received whiplash.
