Trucking Weight Limitations

In the U.S., different states have varying weight limitations for shipments making it challenging to determine the best state to transport your cargo in. To make things easier, we provide a reliable source that allows you to quickly determine which states are best suited for your shipment needs. With this information, you can ensure that your cargo is transported safely and efficiently. While regulations can change and this is meant to serve as basic information for each state, it is recommended to check each state for specific circumstances.
