Which type of vehicle is identified by the abbreviation 'FB'?

The abbreviation 'FB' is commonly used to identify a "Flatbed" truck. Flatbed vehicles are characterized by their open cargo area that is flat and not enclosed, making them suitable for transporting a wide variety of loads that do not fit in traditional enclosed trucks, such as construction materials, machinery, or large items that require loading from the side or top.

Flatbed trucks have specific design features that differentiate them from other types of vehicles, such as forklifts, which are primarily used for lifting and moving materials over short distances, and fastbacks, which refer to a style of car design, not a category of commercial vehicle. Freightliner is a well-known brand of heavy-duty trucks, but the abbreviation 'FB' is not directly associated with vehicle make or model designations. Thus, 'FB' specifically denotes the flatbed design in the context of commercial vehicles.
