What Do You Call the Back of a Semi Truck?

The back of a semi truck is referred to by several names. Most commonly, it is referred to as the trailer or box. This part of the truck is where the cargo is housed and transported.

It is typically made of metal and has one or two doors on the back. The trailer can come in various sizes, depending on how much cargo needs to be transported. It can range from 28 feet to 53 feet long.

The trailer is usually pulled by a truck tractor, which is the cab portion of the semi-truck. It has an engine that powers it and transmits power from the engine to the wheels through a series of gears. The trailer is then connected to the tractor via a fifth wheel coupling, which allows for secure coupling between the two parts.

Another term used for this part of the semi-truck is “reefer” which stands for refrigerated container. This type of trailer has an insulated interior and uses refrigeration systems for cooling or heating cargo, allowing for food items and other temperature-sensitive goods to stay within safe temperatures during transport.

Conclusion:

In conclusion, what do you call the back of a semi truck? Generally, it is referred to as either a “trailer” or “box” while some refer to it as a reefer when it has an insulated interior with refrigeration systems.
