Britain's busiest motorway was forced to close today after a HGV lorry crashed into the back of a van which had broken down.
The white van was torn to pieces in the smash between junctions five and six of the M25 in Surrey.
But despite the devastating wreckage, no one was injured.
Kent Police said the driver of the van had left his vehicle to call for help when the accident happened - a decision which probably saved his life.
A police spokeswoman said the accident happened at around 9.50am near Clacket Lane, causing the M25 to be closed completely in the anti-clockwise direction, while two lanes were closed on the clockwise carriageway.
The Highways Agency reported delays of more than an hour, with traffic queuing back to the M26 in the clockwise direction.
Two lanes of the M25 remained closed in each direction, an agency spokesman added.
