This video was caught on high definition dashcam in Russia, but for whatever reason the footage freezes on a frame every so often. It’s a bit irritating but the violent collision makes up for the irritation.
It would appear that the box truck driver dozed off. His vehicle smoothly progressed into the oncoming lane and crashed head on with a semi. The semi driver noticed that an oncoming truck was invading his lane and tried to avoid it by going as close to the barrier as he could but when they were in each other’s face, the box truck was all the way in his lane.
Given its weight, the semi had much more kinetic energy and delivered a powerful slap to the box truck, pretty much destroying it and its cargo. The crash also sent the female passenger in the dashcam car into a squeal fit.
