Dashcam footage shows a busy motorway, with cars driving at a moderate speed in every lane.
A large white car pulls in to the middle lane, indicating as he slides in.
He causes one car to break hard to avoid crashing into him – but the driver doesn’t stop there.
He keeps his indicator on and clearly intends to try and get into the lane on the far left.
The white car tries to push in front of a black car that can be seen directly in front of the camera.
The black car brakes, but doesn’t let the white car in – but the white car driver doesn’t give up, and pushes his way in front.
Eventually, the black car driver is forced to let the white car in front of him as traffic is beginning to build up around them.
But he soon has his revenge – as the black car is actually an undercover police car.
The police lights come on, and the white car is pulled over onto the hard shoulder.
The car filming drives past the hard shoulder and the clip ends.
The clip was uploaded to YouTube, where it has over 3,300 views.
Commenters loved the video, and one wrote: “Excellent!!!”
The clip of the driver getting caught out by an undercover police officer comes as a video of a thief stealing from a van went viral.
The large van was parked up and the driver was had gone into nearby shop to make a delivery.
He had left the back door open – and a passerby decided to use the opportunity to try and steal from the van.
Dressed in a red tracksuit top and jeans, the man jumps onto the van, and an internal CCTV camera catches him helping himself to items he finds on it.
