The Texas A&M Transportation Institute (TTI) conducted a test with a steel barrier stopping a speeding truck.
The main focus was on the massive 24-foot-wide steel barrier buried 18 inches into the ground to see if it's efficient at preventing a truck's bed from making it one meter pass the barrier, as marked by a blue pole at the Proving Grounds Research Facility. As you can see, the test was a success as even though the truck was doing 50 mph (80 km/h), the bed didn't reach the aforementioned blue pole.
This test was conducted recently and represents a part of a contract TTI has with the U.S. State Department to test several "perimeter security devices" found at embassies as well as other facilities. Dean Alberson from TTI's Crashworthy Structures Program says "the focus is on keeping a terrorist from breaching the barrier" while "the ability of a driver to survive such a crash is not a primary concern."
