B Gross Vehicle Weight (GVW) and Gross Vehicle Weight Rating
(GVWR)
The Gross Vehicle Weight (GVW) must never exceed the Gross
Vehicle Weight Rating (GVWR).
Gross Vehicle Weight (GVW) is the combined total of weight of the
vehicle, driver, passengers, luggage, trailer hitch, trailer tongue load
and any other optional equipment installed on your vehicle. Therefore,
the GVW changes depending on the situation. Determine the GVW
each time before going on a trip by putting your vehicle and trailer on
a vehicle scale.
GVWR is shown on the certification plate located on the driver's door
jamb of your vehicle.
