How Much Weight Can Be on Each Axle of a Semi Truck?

The amount of weight a semi truck can carry is determined by the size and design of the axles. The two main types of axles used on semi trucks are single and tandem. Single axles are typically found in smaller vehicles, while tandem axles are used for larger vehicles that require more stability and greater carrying capacity.

Single axle semi trucks can carry up to 12,000 pounds. This is the legal limit for most states in the U.S.

However, this weight limit can vary depending on the state and local regulations. For example, some states may have a lower weight limit for single axle semi trucks, while other states may have higher limits that allow for more weight.

Tandem axle semi trucks can carry up to 34,000 pounds. This is due to their design which features two axles placed side by side to increase stability and carrying capacity. However, some states may have lower limits that apply to tandem axle semi trucks as well.

Conclusion:

The amount of weight a semi truck can carry depends on its size and design as well as local regulations. Generally speaking, single axle semi trucks can carry up to 12,000 pounds while tandem axle semi trucks can carry up to 34,000 pounds. It is important to check with local regulations before loading a truck for any specific trip in order to ensure compliance with all laws and regulations.
