What mode of transport is responsible for shipping approximately 54% of hazardous materials annually in the nation?

The primary reason that road transport accounts for the shipping of approximately 54% of hazardous materials annually in the nation lies in its accessibility and flexibility. Road transportation allows for direct delivery to specific locations, which is particularly important for hazardous materials that require timely and secure transport.

Trucking facilities can reach areas that are not serviced by rail or waterways, enabling the transportation of hazardous goods from manufacturers to distribution centers, retailers, or consumers without the need for transfer between modes of transport. This single-mode delivery reduces handling risks and the potential for incidents during transfers.

Additionally, the extensive network of highways and roads supports the continuous movement of freight, making it a favored option for industries that require the swift and safe transport of hazardous materials. The ability to quickly respond to demand and the widespread infrastructure that facilitates road transport significantly contributes to its high percentage of hazardous material shipments.
