What is "intermodal transport" in the context of HAZMAT?

Intermodal transport refers to the process of moving goods using more than one mode of transportation for the duration of their journey. In the context of hazardous materials (HAZMAT), it often involves the combination of rail and truck transport. This method allows for the efficient handling of HAZMAT shipments by utilizing different types of transport that are best suited for various segments of the journey. For example, hazardous materials may be transported by rail over long distances due to efficiency and lower costs and then transferred to trucks for the final delivery to their destination. This approach improves logistical flexibility and helps ensure that HAZMAT is transported safely and effectively.

The other options focus on limited transportation methods, such as a single mode or exclusive air transport, which do not capture the essence of intermodal transport.
