Trucking Terms: GVM vs Carrying Capacity


Understand what the terms Gross Vehicle Mass (GVM), TARE Weight and Carrying Capacity mean for your truck.

Understanding the different ways a truck's weight is measured and why, is key to ensuring safe and efficient operation of the vehicle. This quick and easy guide explains the three most important measures and how to identify them.

Gross Vehicle Mass (GVM)

  • The maximum weight a vehicle is permitted to attain.
  • GVM is determined by the vehicle manufacturer and is based on the specific weight each axle is designed to carry.
  • The GVM is stamped on the compliance plate and appears on registration papers.

TARE Weight

  • The truck’s unloaded weight. Fuel included.
  • Other terms used to describe TARE Weight are Unladen Mass, Unloaded State, Unladen Weight and Empty Weight.
  • You can find TARE Weight on registration papers.

Carrying Capacity

  • The maximum load weight a truck can carry.
  • Carrying Capacity can be simply calculated by subtracting the TARE Weight from the GVM.
