A dramatic security camera video has emerged from China showing two lorries colliding on the motorway causing a massive explosion.

In the clip, which was filmed in Hangzhou, Zhejiang Province on July 17, one lorry hits the side of another which is parked at the side of the motorway.

The collision appears to spark a small explosion inside the moving lorry which then triggers a huge blast.

The lorry's burning cargo spills all over the motorway leaving a trail of fire.

Amazingly, no-one was injured in the incident and the driver of the lorry which exploded can be seen emerging from the cab to inspect the very considerable damage.

The driver was reported to have been carrying paint.
