Trucks lift, dump, and carry things every day, everywhere. Didyou know that...
　　.Some trucks can weigh as much as ten elephants puttogether.
　　.Flatbed trucks can carry other trucks, houses, and even a spaceshuttle!
　　.Semitrailer cabs can have a bed behind the front seat so thatdrivers can pull over and rest on long trips.
　　.Road-train trucks pull multiple trailers at the same time, justlike a locomotive pulls freight cars on a train.
