Apparently the story goes:
[ PS: Here is the Snopes link verifying it http://www.snopes.com/photos/accident/culvert.asp
First pic shows where this driver
broke through the guardrail, on the right side of the culvert,
where people are standing on the road, pointing.
The pick-up was traveling about 75 mph, from right to left,
when it crashed through the guardrail.
It flipped end-over-end, bounced off and across the culvert outlet,
and landed right-side-up on the left side of the culvert,
facing the opposite direction from which the driver was traveling.
The 22-year-old driver and his 18-year-old passenger
were unhurt , except for minor cuts and bruises.
Just outside Flagstaff , AZ on U.S. Hwy 100.
Now, look at the second picture below . . .
