Intermodal transportation involves the transportation of containers of cargo among multiple modes of transport (rail, ship, truck, etc.) without unloading the containers. National Safety Code Standard 10 (Cargo Securement) defines an “intermodal container” as a reusable, transportable container that is specially designed with integral locking devices to secure it to a container chassis vehicle. To transport an intermodal container, you must secure it to the chassis of your vehicle with the integral locking devices so it can’t move around.
