Gross axle weight (GAW) is the actual weight of a fully loaded vehicle carried by how many axle(s)?

Gross axle weight (GAW) specifically refers to the actual weight carried by a single axle of a vehicle when it is fully loaded. This measurement is crucial because it helps ensure that the vehicle does not exceed the weight limits set by regulations for individual axles. Those limits are in place to promote safety, protect road infrastructure, and ensure the vehicle's handling and performance characteristics are maintained.

In the context of vehicle operation, recognizing GAW is important for manufacturers, drivers, and regulatory authorities. Understanding how much weight is distributed across each axle allows for better weight management, which can affect everything from braking efficiency to tire wear.

When a vehicle's gross axle weight exceeds the recommended limits, it can lead to various issues such as increased risk of tire blowouts, impaired steering, and reduced braking capability, which can jeopardize safety on the road. Therefore, it's crucial to monitor and manage GAW, which highlights the importance of this concept in the operation of commercial and heavy-duty vehicles.
