What type of container can be transferred between modes of transportation without being offloaded?

• A. Nonbulk containers
• B. Intermodal containers
• C. Aircraft
• D. Highway container

Answer: (B)

Intermodal containers are designed to move intact across different modes of transportation, such as ships, trains, and trucks, without unloading the cargo. Their standardized dimensions and corner fittings (twist locks) allow handling equipment at each mode to lift and secure the container seamlessly, so the contents remain sealed during transfers. This cross‑modal compatibility is what enables efficient, safe movement of goods, including hazmat, because the material stays contained while the container is moved from one mode to another. Other options don’t provide this seamless, multi‑mode transfer capability, as they are tied to specific handling methods or modes.
