A stretch of the M20 was temporarily closed and two people were seriously injured after more than 30 vehicles were involved in a crash.
Kent Police said it happened on the London-bound carriageway near Hollingbourne, Maidstone, around 6.41pm on Saturday.
There was "thick fog" in the area at the time, according to National Highways, and the crash forced the closure of the motorway in both directions between junctions 8 and 9 for several hours.
