What Is a Semi-Truck vs 18 Wheeler?

A semi-truck and an 18 wheeler are often used interchangeably, but they are actually two different types of vehicles. Semi-trucks are large commercial trucks that can be used for a variety of purposes, such as transporting cargo, materials, and goods. An 18 wheeler is a specific type of semi-truck that has eighteen wheels and is used mainly for hauling heavier loads over long distances.

Semi-trucks typically have two axles and four to six tires. They can be found in a variety of sizes, ranging from small pickup trucks to large tractor trailers.

The most common type of semi-truck is the Class 8 or “big rig” which is usually used to transport goods across the country. Most semi-trucks have a maximum gross vehicle weight rating (GVWR) of 33,000 pounds or more.

An 18 wheeler is an even larger type of semi-truck with up to eighteen wheels and an even higher GVWR. These trucks are typically used to haul heavier loads such as construction equipment, oil tankers, and other large cargo items across long distances. They are also sometimes used for recreational purposes such as camping trips or recreational vehicle transportation.

The main difference between a semi-truck and an 18 wheeler is the size and weight capacity. Semi-trucks typically have two axles with four to six tires whereas 18 wheelers have up to eighteen wheels with an even higher GVWR. Additionally, 18 wheelers usually carry heavier loads than their smaller counterparts.

In conclusion, a semi-truck is a large commercial truck that can be used for various purposes while an 18 wheeler is a specific type of semi-truck with up to eighteen wheels and an even higher GVWR that is mainly used for hauling heavy loads over long distances. The main difference between the two types of vehicles lies in their size and weight capacity.
