Richard Hammond, host of the world's biggest car show Top Gear, takes the ultimate driving test in his new series Richard Hammond's Crash Course. As he travels across the U.S., Hammond learns how to operate America's largest and most dangerous vehicles. Immersed in some of the country's most extreme environments, he has only days to master the skills it takes to maneuver the monstrous machines, a task it takes years for people to achieve. Throughout his journey Hammond works closely with the local experts who operate these machines daily while getting a true taste of American hospitality.
