What Does GVWR Mean?

2020 Ford Super Duty on a dirt road
When it comes to pickup trucks, cab chassis trucks, and other commercial vehicles, gross vehicle weight rating (GVWR) is an important specification to know and understand. What does GVWR mean? GVWR is manufacturer-specified, and tells you the maximum operating weight for a truck. This is an important figure to know, because there are laws surrounding GVWR that vary from location to location. Below, you’ll find more information on GVWR and how it’s determined.


How is GVWR Calculated?

Years ago, gross vehicle weight rating was calculated by adding the gross axle weight ratings (GAWRs) together. Today, the process is much more involved. If you were to add the GAWRs of a truck, it’s likely the sum will be much lower than the GVWR calculated by the OEM. Safety systems with automatic braking and stability control systems, for example, can reduce the GVWR. Manufacturers complete thorough tests to ensure the GVWR given is as accurate as possible. Adding the GAWRs will give you a ballpark estimate of a truck’s GVWR, but the figure shouldn’t be taken at face value.


What are the Laws Involving GVWR?

When you drive a commercial vehicle, it’s imperative to be aware of the limitations surrounding GVWR, which include:

  • On certain roads, vehicles weighing over 6,000 pounds are prohibited. (Review the limitations in your area to make sure you’re operating your commercial vehicle legally.)
  • Vehicles with a GVWR of over 8,500 pounds must carry public liability coverage, according to the Motor Carrier Act of 1980.
  • Vehicles or combinations over 26,000 pounds GVWR must be driven by a driver with a Commercial Driver’s License (CDL) or a Non-Commercial Class A or B license. It should be noted that CDLs are often required for vehicles with GVWRs under 26,000 pounds, including passenger vans carrying 16+ passengers or vehicles carrying hazardous/dangerous materials.
