This dashcam video was just a few feet away from showing us two semi trucks crashing head to head at highway speeds. These cable barriers are designed to slow crashing vehicles. While they did their job and prevented a head on collision, I'm sure this trucker would have liked if they were a little bit stronger so the evasive actions weren't needed.
The work truck ahead looks like he exited the highway after the near miss out of sheer terror. Can you blame him though?
