Some states have lower single axle weight limits than the federal limit. For example, the maximum single axle weight limit in California is 18,500 pounds (8,391 kg).
Trucks that exceed the single axle weight limit are subject to fines and penalties. The amount of the fine can vary depending on the state and the amount of weight over the limit.
In addition to the single axle weight limit, trucks are also subject to gross weight limits. The gross weight limit is the total weight of the truck, including the weight of the truck itself, the cargo, and the passengers. The gross weight limit for trucks varies depending on the number of axles on the truck.
Trucks that exceed the gross weight limit are also subject to fines and penalties. The amount of the fine can vary depending on the state and the amount of weight over the limit.
