In the United States, the maximum axle weight for trucks is typically regulated by state laws. The exact weight limit can vary from state to state, but the most common maximum axle weight limit is 20,000 pounds (9,072 kilograms) for a single axle and 34,000 pounds (15,422 kilograms) for a tandem axle. Some states may have different weight limits for specific types of trucks or axles.
It is important to note that truck axle weight limits are set to ensure the safety of roads and bridges and to prevent excessive wear and damage. Overweight trucks can cause significant damage to infrastructure and pose a safety hazard to other road users. Therefore, it is important to comply with the axle weight limits and enforce them.
