Dash cam footage has caught the moment a car flipped 360 degrees in the air after it was forced off the motorway by another motorist that had lost control of his Jaguar.
The Jaguar can be seen swerving to avoid hitting the back of another car in the middle lane but then loses complete control, cutting the other car up and forcing it up a steep verge at 50mph, causing it to flip in the air.
The incident happened near junction 14 of the M4.
The driver of the vehicle which captured the moment on dash came told MailOnline: “After pulling over the guy in the Jaguar got out and went to apologise to the guy in the other car.
“Thankfully, he had managed to crawl out.
“I then overheard him saying ‘you nearly killed me'”.
