Truck Types Classification by Weight Limit

When you have to choose a truck, don’t choose the best-looking model. Choose the type of truck whose weight classification is enough to haul the cargo type you plan to haul.

You can’t haul heavy freight on a light-weight truck, and you shouldn’t haul low-weight freight on heavy-duty trucks. It makes no sense. Right?

To make this logistical process easier, in the United States, all the commercial trucks are classified into eight different classes based on their gross vehicle weight rating (GVWR). Also, the Federal Highway Administration (FHWA) grouped these commercial truck classifications into three major groups.


Understand these truck classifications helps you understand how to choose the right type of truck to haul the freight and what type of CDL the driver needs to have.

Find below the explanation of the truck types classified by weight and what type of commercial trucks fit into each category.

What is Gross Vehicle Weight Rating?

The GVWR is a safety truck's standard that is used to prevent their overloading.

This number is the maximum weight of a vehicle that ensures the safe operation of the bobtail plus trailer. Find out what is a bobtail truck.

The weight rating of the vehicle includes the net weight of the vehicle plus the passengers, the drivers, fuel, and cargo and it doesn't change after a manufacturer determines it for a vehicle.

The vehicle manufacturer determines the GVWR by considering the combined weight of the strongest weight-bearing components, such as the axles; and the weaker components, such as the body, frame, suspension, and tires. This determines the vehicle's class, which determines the regulations that it needs to follow.

In some cases, drivers may need to obtain a certain type of license before driving a vehicle.

For example, the GVWR of your vehicle might be 7,000 pounds. If the curb weight is 5,000 pounds and the typical weight for your passengers and fuel is 500 pounds, then your vehicle can safely handle a payload of 1,500 pounds.

So, knowing the GVWR and the weight of the freight that you need to haul, you may easily understand what type of truck you need to do the job legally.

They are responsible for the safe operation of commercial vehicles that transport the products we used daily.

Vehicle regulations

If a vehicle has a GVWR of more than 26,001 pounds and is used for a business, including nonprofits, then it is subject to federal and state safety regulations for the safe operation of commercial motor vehicles.

Vehicles over this weight are required to stop at state weigh and inspection stations, and drivers must follow regulations concerning hours of service and medical examination.

A driver does not need a CDL to operate a Class 1 through 6 vehicle but each one with a GVWR over 26,001 pounds has to be identified with the name of the company and the DOT number.
