A semi-truck is an articulated vehicle that is composed of two sections connected by a fifth wheel. The front section is typically called the tractor, while the rear section is referred to as the trailer. The tractor is powered by an engine, while the trailer carries goods and materials. Because of its size and weight, a semi-truck requires special licenses and permits in order to operate on public roads.
The term “18-wheeler” is often used to refer to a semi-truck because it has 18 wheels – four on the tractor, and fourteen on the trailer. It was also formerly known as a “big rig” because of its size and popularity among truckers in the United States.
The term “18-wheeler” has become a popular way to refer to any large truck or semi-truck regardless of its number of wheels.
Semi-trucks are essential for transporting goods across long distances quickly and efficiently. They are able to carry much larger loads than smaller vehicles, making them ideal for transporting items such as furniture, appliances, building materials, and other large items that cannot be shipped using smaller vehicles. Semi-trucks can also be used for hauling hazardous materials such as chemicals, fuels, and other flammable substances due to their size and specialized equipment.
Semi-trucks have come a long way since they were first introduced in the early 20th century. Today’s trucks are equipped with advanced safety features such as anti-lock braking systems (ABS), airbags, electronic stability control (ESC), lane departure warning systems (LDWS), automatic emergency braking (AEB), adaptive cruise control (ACC) and other technologies that help reduce the risk of accidents on highways and other roadways.
