Containerized loads are typically used when:

Containerized loads are primarily utilized for their efficiency and versatility in transporting goods, particularly when freight needs to be transferred partway by rail or ship. This method of transport allows for standardized containers that can easily be loaded, unloaded, and transferred between different modes of transportation without needing to handle the actual cargo itself. This intermodal transport system streamlines logistics, reduces loading times, and enhances security since the cargo remains sealed within the container until it reaches its final destination.

The option suggesting that containerized loads are handy only for short-distance hauls limits their use, as containers are commonly used for long-distance shipping as well. Similarly, the assertion that they are secured by the driver overlooks the fact that the security of containerized loads comes from the container's inherent design and sealing, not solely from the driver. Lastly, the claim regarding weight limits is misleading because all transport modes, including those utilizing containerized loads, are governed by specific weight regulations and limits to ensure safety and compliance on public roadways.
