This is the horrifying moment a car with a baby in the back seat careers across a motorway on its roof, leaving a trail of sparks behind it before coming to rest on the verge.
The terrifying crash was caught on the dashboard camera of a lorry which was not involved – but whose driver witnessed the carnage.
On a wet and grey day in West Wales, the lorry can be seen driving along in the inside lane when a white Volvo saloon-type vehicle suddenly slides into shot on its roof.
It is so close it almost fills the camera’s frame as it sends sparks flying, reports Wales Online .
The white car’s driver had his wife and four-month old baby in the vehicle, but incredibly they all escaped without any serious injuries.
A blue hatchback car also involved in the crash smashes head-on into the central reservation before coming to rest having completed a 360-degree turn.
But the incident shocked the driver of the lorry, which is owned by Llanelli-based haulage and logistics firm Owens Group.
The company has now released the footage, filmed on the M5 in 2014, to illustrate the benefits of having a forward-facing dashboard camera attached to each of its vehicles.
Mike Colborne, health and safety manager at Owens Group, said the lorry involved happened to be the only one fitted with a camera at the time, with the company taking part in a trial to see what the benefits would be.
And the footage proved the lorry driver was not to blame for the accident, clearing the company of any responsibility from an insurance point of view.
Mr Colborne said: “Our driver helped as best he could and phoned the police.
“Everybody was able to get out.
