Aggregate working load limit = GAWR x number of axles
Where:
* GAWR is the gross axle weight rating for each axle
* Number of axles is the total number of axles on the vehicle
For example, if a commercial motor vehicle has a GAWR of 12,000 pounds and 4 axles, then the aggregate working load limit would be 48,000 pounds.
It's important to note that the aggregate working load limit is just one of several factors that determine the maximum weight that a commercial motor vehicle can legally carry. Other factors include the vehicle's GVWR, the bridge weight formula, and the axle weight distribution.
