Look at the picture below and you can see where this guy broke through the guardrail, on the 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 rail. 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.
Now, look at the second picture....
