This is the terrifying moment a driver lost control of his vehicle and smashed into a roadside barrier after he had a seizure at the wheel.

The dramatic dashcam footage was captured by another driver at Bredbury Junction on the M60, near Stockport.

The clip shows a Nissan hatchback suddenly veer across all three lanes of the motorway before crashing into the central reservation.

After crashing into the barriers, the Nissan is sent reeling back in the direction it came from, with smoke billowing out of it.

Fortunately, it eventually stops moving and comes to rest on the hard shoulder and not in the middle of traffic.

The person recording the scary incident immediately stops his car to help the driver of the Nissan.
