I pretty much have absolutely no backinfo. The video shows the apparent aftermath of a fatal traffic accident. The man is down on the road next to his bike, with guts shot out of his abdominal cavity due to the crushing pressure of a truck that had allegedly run him over.
There is also a car with twisted wheels next to the corpse of the biker. I wonder if that car was somehow involved in causing the biker to lose balance and fall under the truck?
Props to Best Gore member @momox for the video:
