Watch: This incredible dashcam footage has divided the internet - but who's to blame?
Drivers who try to skip the traffic queue can be infuriating for other road users - and this truck driver showed just how mad he was.
This incredible dashcam footage shows a car attempting to merge with traffic in a tunnel, perhaps a little sneakily.
However, the truck driver in the lane he wishes to merge with refuses to allow him join the traffic.
The truck repeatedly closes the gap between himself and the vehicle in front (with the dashcam) so that the car cannot move in.
Having had enough of the car's attempts, the truck drives into the back of the car before eventually letting the driver merge.
The footage has divided opinion between praise for the truck driver standing his ground and incredulity that he could let a crash occur.
