What percentage of freight tonnage is shipped by all forms of transportation excluding trucks?

The correct answer reflects that 29.9% of freight tonnage is shipped by forms of transportation excluding trucks. This statistic is significant as it highlights the reliance on trucking within the overall freight transportation landscape.

Understanding that trucks are a major component of freight transportation is crucial since they account for a large portion of total freight tonnage. The percentage given excludes other modes such as rail, air, and maritime transport, showing that while they are essential, they collectively represent less than a third of the total freight moved in terms of tonnage. This emphasizes the importance of trucks in ensuring efficient and timely delivery of goods across various distances, which is a key focus for logistics and supply chain professionals.

The absence of larger percentages indicates that while other transportation modes play a vital role in the logistics chain, trucking remains the dominant force in freight transport, responsible for the majority of tonnage moved across the country. Understanding this distribution helps in strategizing logistics, improving efficiency in supply chains, and making informed decisions about transportation management.
