Drivers using a motorway had a lucky escape when a car transporter lorry flipped over leaving wrecked vehicles dotted across the carriageway.
One of the cars being transported along the M1 on the double-deck wagon even plummeted over the side of the motorway ending up by the side of a local road running underneath.
But West Yorkshire Police said no vehicles other than the lorry and its cargo were involved in the incident, which happened on Tuesday morning on the northbound carriageway, close to junction 39, south of Wakefield.
A spokesman said there were no injuries.
Most of the nine cars being carried on the stricken vehicle stayed on the northbound carriageway but one crashed onto the opposite side of the road, police said.
The northbound carriageway was completely closed and is likely to remain shut for some time.
The southbound carriageway was partially closed but has now reopened.
Chief Inspector Paul Hepworth said: "We would ask drivers to be patient when travelling near to junction 39 of the M1 following an accident in which a car transporter lost its load of nine cars earlier today."
