Is it illegal to load containers in flat cars?

Illegal. For a dump truck with a detachable box, if the box is welded on a flat plate to transport goods, and the structure, frame or characteristics of the original car are changed, it should be considered as an illegal act of modifying the vehicle without authorization.

If the container is only placed on the flat plate without changing the structure, frame or characteristics of the original car, it cannot be regarded as the act of modifying the car without authorization.
