Freight transportation keeps the economy moving by connecting manufacturers, farms, retailers, warehouses, and consumers with the goods they need. Trucks, trains, ships, and aircraft help businesses reach suppliers and customers across the country and around the world. Efficient freight networks can support economic growth by reducing delays, expanding market access, creating jobs, and keeping supply chains functioning.
Freight Connects Businesses With Suppliers and Customers
A modern economy depends on companies being able to move raw materials, components, and finished products between locations. Freight transportation gives manufacturers access to suppliers beyond their immediate region while allowing businesses to sell products across much larger markets. The Federal Highway Administration notes that better freight connections can expand both supplier and customer markets, helping businesses obtain inputs more efficiently and reach more buyers (source).
That connection matters across nearly every part of the economy. Farms need transportation to move food to processors and stores, manufacturers depend on incoming materials, and retailers rely on regular deliveries to maintain inventory. The U.S. Department of Transportation identifies reliable freight supply chains as an important part of connecting producers, shippers, and consumers in domestic and international markets (source).
Trucking Makes a Major Contribution to Economic Activity
Trucking plays an especially large role because trucks can move freight directly between factories, distribution centers, stores, ports, and other destinations. Bureau of Transportation Statistics data shows that trucking contributed $621.4 billion to U.S. gross domestic product in 2024, more than any other individual freight transportation mode. That total included both transportation services provided by trucking companies and trucking operations performed internally by other businesses (source).
Freight transportation also supports a substantial workforce. Heavy and tractor-trailer truck drivers alone held about 2.2 million jobs in 2025, according to the Bureau of Labor Statistics. Those drivers work across trucking, wholesale trade, manufacturing, construction, and other industries, showing how transportation employment extends throughout the broader economy (source).
Different Freight Modes Keep Supply Chains Moving
Trucking may handle a large share of domestic freight activity, but the economy depends on a network of transportation modes working together. Railroads, vessels, aircraft, pipelines, and trucks each move different commodities and serve different routes. Many shipments also travel by more than one mode before reaching their destination. The Federal Highway Administration and Bureau of Transportation Statistics track freight flows across all major modes through the Freight Analysis Framework, reflecting how interconnected the national system has become (source).
A shipment arriving by ocean vessel, for example, may continue by rail and eventually reach a warehouse or store by truck. Reliable connections between modes help companies keep products moving without unnecessary delays. When one part of the system experiences disruption, the effects can spread to manufacturers, distributors, retailers, and customers that depend on goods arriving on schedule.
Freight Transportation Supports U.S. Trade
Freight networks are also essential to international commerce. Goods moving into and out of the United States depend on trucks, railroads, vessels, aircraft, and pipelines to connect businesses with overseas and North American trading partners. In 2025, freight moving between the United States, Canada, and Mexico was valued at about $1.6 trillion, according to the Bureau of Transportation Statistics (source).
Trucking carried more than $1 trillion of that cross-border freight. Trucks accounted for 55.7% of the value of U.S.-Canada freight and 73.6% of U.S.-Mexico freight in 2025. Rail, vessels, pipelines, and air transportation moved billions of dollars more, illustrating why efficient freight infrastructure is important for manufacturers, agricultural producers, retailers, and other businesses involved in international trade (source).
Reliable Freight Can Lower Business Costs and Improve Productivity
The economic value of freight isn’t limited to the amount of cargo being transported. Speed and reliability can influence how much businesses spend on inventory, warehousing, transportation, and production. According to the Federal Highway Administration, shorter and more dependable transit times can help companies reduce buffer inventory, lower logistics costs, and gain access to larger supplier and customer markets (source).
Those improvements can make businesses more productive because fewer resources are tied up compensating for transportation delays or unreliable deliveries. Efficient transportation infrastructure can also improve connections between regions, support trade, and reduce costs for businesses and individuals. The U.S. Department of Transportation identifies reliable transportation networks as an important contributor to productivity, investment, job opportunities, and economic competitiveness (source).
Freight Keeps Economic Activity Moving
Freight transportation drives the economy by doing far more than carrying products from one destination to another. It connects businesses with suppliers, provides access to larger markets, supports millions of jobs, facilitates international trade, and helps companies manage inventory and production more efficiently. Trucks are particularly important, but rail, air, water, and other modes all contribute to an interconnected freight system.
When freight networks operate reliably, businesses can receive materials when needed and get finished products to customers more efficiently. Delays or disruptions can create effects throughout a supply chain, while stronger transportation connections can support productivity and economic growth. From raw materials entering a factory to finished goods reaching a store or home, freight remains a fundamental part of how the U.S. economy functions.
