Intermodal containers are defined by their ability to move cargo between different modes of transportation—sea, rail, and road—without unloading the contents. This is made possible by standardized sizes and locking fittings that let ships, trains, and trucks handle the same container with compatible equipment. Because of this design, the container system enables seamless transfers across modes, which is what sets intermodal containers apart.

That’s why the statement describing them as something that can be moved from one mode of transportation to another is the best fit. They aren’t limited to road transport, they aren’t used only for liquids, and while cranes may be used in handling, a special crane isn’t a defining requirement—the standard equipment used at ports and on rail yards or with road chassis suffices.
