Define "overweight" concerning commercial vehicles.

The term "overweight" in the context of commercial vehicles refers specifically to a situation where a vehicle exceeds the maximum weight limits that are legally established. Each state, including Arizona, has set specific weight limits for commercial vehicles to ensure safe operation on public roads. These limits are determined based on factors such as road capacity, safety considerations, and the structure of highways and bridges.

When a vehicle is classified as overweight, it typically means that the combined weight of the vehicle and its load surpasses these legal limits, leading to potential safety hazards such as diminished handling capabilities, increased stopping distances, and greater wear and tear on infrastructure. Compliance with weight restrictions is crucial for maintaining road safety and prolonging the lifespan of highways.

In contrast, other choices discuss different scenarios that do not pertain to the definition of "overweight" for commercial vehicles. For example, meeting minimum weight requirements or operating below the weight limit indicates compliance rather than violation of weight laws. Similarly, operating without a proper permit relates more to legal documentation and permissions rather than the weight itself.
