There are several ways a vehicle can be overweight; such as over the registered weight, over tire limits, over an axle weight, or over gross weight. Depending on which way a vehicle is overweight depends on what there is for a enforcement tolerance. Depending on the weight violation, a tolerance will vary from a zero tolerance to a 10% tolerance. It also depends on whether the vehicle is being operated in conformance with a special permit. However, there is no weight statute that uses the Gross Vehicle Weight Rating (GVWR) as the basis for a vehicle’s legal weight limit.
