This video showing a 15,000-pound truck crashing into a barrier at 50 miles per hour has gone viral on sites like the the Houston Chronicle. The test, conducted by the Texas A&M Transportation Institute, has nothing to do with the safety of the truck or driver. It's about how effective a new perimeter barrier could be at protecting U.S. embassies and other facilities around the globe. The 42-inch-tall pipe structure is made of steel and concrete. The test was considered a success because the bed of the truck and its cargo were prevented from passing the barrier.
