In its continuing effort to keep our streets safe, truTV exposes 20 of the dumbest drivers in the world. There's the jeep driver whose off-roading misadventure sends him tumbling down the side of a cliff, the amateur storm chasers who race into the center of a dangerous hailstorm, and the 14-year-old who takes his parents' car out for a spin, then crashes it. Ride along with Todd Bridges, Leif Garrett and the rest of our celebrity commentators as they administer their own roadside sobriety and intelligence tests.
