This is the terrifying moment a motorist was forced to slam on his brakes to avoid hitting an abandoned car that rolled onto the motorway.
Dashcam footage from Daniel Richardson's car shows a battered Ford Ka slowly roll across a number of lanes on the M1 with no driver behind the wheel.
The potentially fatal incident was recorded between junctions 27 and 28, just south of Mansfield, Nottinghamshire, while Richardson was driving to work.
He told the Daily Mail: "I was on my way to work one morning when I noticed a car ahead of me reversing back into the motorway.
"There was a lorry parked up on the hard shoulder and, from the state of the car, it was obvious there had been some kind of collision.
"I can only imagine the driver must have forgotten to put on the handbrake after leaving his vehicle."
