A BRIT has captured shocking footage of a road rage thug climbing into a lorry to attack the driver.
The fuming motorist used his car as a roadblock before crawling in through the window to carry out his assault.
The clip, reportedly filmed in Slough, Berkshire, showed an articulated lorry pulling up to a set of traffic lights.
As it stopped, a black hatchback pulled alongside it at speed before braking sharply.
The driver of the car swerved across the inside lane, positioning the vehicle so it blocks the HGV from moving forward.
He then got out of the vehicle, clearly agitated, and walked purposefully towards the lorry.
At first, he tried to open the larger motor’s door to confront its occupant.
He could be heard shouting: “Open the f****** door.”
Fortunately for the lorry driver, the door was firmly locked.
Many people might have given up at that point, but the raging road user came up with a bizarre solution.
Instead of backing off, he used the step on the doorframe and the open window to scale the door and come face to face with his target.
He then appeared to throw a punch through the window before apparently grabbing hold of the other driver.
The person filming the ordeal was left baffled as the road rager clambered into the cab, with only his shoes visible.
The cameraman said: “It’s going to kick off.
“He jumped in there man.
“They’re beefing in there.”
And social media commenters were equally bemused.
One wrote: “He wasted no time jumping in that lorry.”
Another added: “People never cease to be wild.”
