Why Is It Called Semi Truck?

A semi truck, also known as a semi-trailer truck, tractor-trailer, or big rig, is a large capacity vehicle used to transport goods and materials. It is an important part of the freight transportation industry and is often seen on highways or in large cities. Semi trucks can be found in many different sizes and configurations depending on the particular needs of their owners.

The term “semi” derives from the fact that it consists of two parts: a tractor unit and one or more trailer units. The tractor unit is the cab that contains the engine, transmission, and steering system. The trailer unit is composed of a frame and chassis with axles for carrying cargo.

Semi trucks have been around for more than 100 years and have evolved over time. In the early days, they were pulled by horses or oxen.

Later, steam engines replaced these animals as the primary power source for semi trucks. As technology improved, diesel engines became popular because they provided greater fuel efficiency.

Today’s modern semi truck can carry up to 80,000 pounds and range in length from 17 feet to 53 feet long. They are equipped with features such as air brakes, anti-lock brakes, electronic stability control systems, and advanced GPS navigation systems that allow drivers to locate their exact position on the road at any given time.
