In a commercial zone, what is the maximum weight allowed on any single axle?

In a commercial zone, the maximum weight allowed on any single axle is 22,400 lbs. This weight limit is established to ensure safety and stability while vehicles are operating in areas designed for commercial activities. The specified weight helps prevent structural damage to roads and bridges, which can occur if vehicles exceed recommended weight limits.

Higher weight limits, such as those mentioned in the other options, are typically applicable under different regulations or contexts, often in reference to total vehicle weight or in specific scenarios not related to single axle restrictions. For instance, 20,000 lbs might apply in certain circumstances, but it is not the maximum allowed in a commercial zone, which is set higher to accommodate the needs of commercial vehicles while maintaining safety standards.
