Weirdly not in Russia this time.
The following footage was shot on I-95 in New Jersey. The man behind the camera was forced to stop by one semi that stopped in front of him, and then he films as a second semi loses control and crashes behind him, and then also a bit to his left. We don't see or hear any sort of reaction from the driver whatsoever, but other noises can be heard, so we know this isn't just a silent flim. The video description says that he called 911 the very second that the video stops.
It goes on to say he also stayed until the emergency services arrived, and that there were no major injuries.
