What does the gross axle weight rating (GAWR) indicate?

The gross axle weight rating (GAWR) indicates the total load carrying capacity of the axles. It represents the maximum weight that each axle is rated to safely support when the vehicle is in operation, including both the weight of the vehicle itself and any additional load it carries. Understanding GAWR is crucial for ensuring that the vehicle is not overloaded beyond its designed limits, which can lead to decreased performance, handling issues, and potential safety hazards.

By adhering to the GAWR, drivers can maintain safe operating conditions and prevent excessive wear or damage to the vehicle’s suspension and tires. The other options presented do not align with the definition of GAWR, as they refer to different aspects of vehicle weight management. For instance, the weight supported by the engine pertains to engine load, while trailer weight concerns the total weight of additional equipment carried by the vehicle. Weight distribution focuses on how the weight is balanced between the front and rear axles rather than the capacity of the axles themselves.
