Even though I don’t have any background information about this video, nor do I speak Portuguese, we see so many videos from Brazil at Best Gore, I feel pretty confident assuming that this one is also from Brazil.
The video shows a passenger car that looks like an older model Toyota Corolla, getting unstuck from under a truck. It would appear that the car rear-ended the truck at a high rate of speed.
Once freed, the wreck reveals a dead family inside. Two adults on front seats, and two children on rear seats all appear to have died in the crash. A tragic end to a bloodline.
Props to Best Gore member @african-angel for the video:
