GVWR is an acronym that means the “Gross Vehicle Weight Rating”, and is related but not similar to the GVW or “Gross Vehicle Weight”. Gross Vehicle Weight instead refers to the total weight a vehicle can effectively and safely operate under, while the Gross Vehicle Weight Rating is actually the score or weight limit set for safe operation by the chassis manufacturer. Not paying attention to this can cause drivers/carriers to overload (and potentially damage) their vehicle.
