Look at the picture and you can see where this guy broke through the guardrail, right side where the people are standing on the road (pointing). The pick-up was traveling from right to left when it crashed through the guardrail. It flipped end-over-end, across the culvert outlet, and landed right side up on the left side of the culvert, facing the opposite direction from which he was traveling. http://www.snopes.com/photos/accident/culvert.asp#photo
