A 26-year-old pedestrian was airlifted to hospital on Monday with “life-threatening injuries” after being involved in a crash with two vans on the M8.
A stretch of the motorway was closed for five hours on Monday night after the horror crash.
The pedestrian was taken by air ambulance to Queen Elizabeth University Hospital in Glasgow with life-threatening injuries.
Road Policing officers are now appealing for information following the accident on the M8 westbound at Harthill.

The crash involved a grey Renault Traffic SL28 van, a Volkswagen Crafter van and a 26-year-old male pedestrian.
