Tractor Trailer
Tractor Trailer is that some trucks are a solid unit, such as a van, but many have three main units. The front section where the driver sits is called the cab or the tractor (because it pulls a load). Cargo is loaded into the metal box (container), which is loaded onto the wheel base called a chassis or a trailer. These big trucks are often also called 18-wheelers.
