Which type of cargo is NOT suitable for a flatbed truck?

Flatbed trucks are specifically designed to carry a wide variety of cargo types, especially those that are heavy and unruly, such as heavy machinery, wooden pallets, and construction materials. However, they are not suitable for transporting liquid cargo that requires a tank.

Liquid cargo necessitates a specialized transport method to prevent spillage and ensure safety. Tankers are designed with specific features to securely contain and prevent leakage of liquids, which flatbed trucks lack. The open nature of a flatbed truck would mean that any liquid could easily spill during transport, which poses safety hazards and potential environmental risks. Therefore, liquid cargo should be moved using tank trailers specifically designed for that purpose, making them the appropriate option for transporting liquids safely and effectively.
