How Big Is the Trucking Industry in the United States?

The U.S. trucking industry is enormous. It moves goods between factories, farms, warehouses, ports, stores, and homes. It also supports millions of jobs and generates hundreds of billions of dollars in freight revenue each year.

But how big is the trucking industry in real numbers? And what does its size mean for truck drivers, owner-operators, dispatchers, and fleet owners?

The American Trucking Associations (ATA) reported that the industry generated $906 billion in gross freight revenue in 2024 and moved 11.27 billion tons of freight. Trucks accounted for approximately 72.7% of the nation’s domestic freight tonnage that year.

 

These figures show why trucking remains central to the American economy. However, industry size is about more than revenue. It also includes jobs, businesses, equipment, freight demand, and the services that keep goods moving.

How Big Is the Trucking Industry? Key Statistics

Here are some of the most useful figures for understanding the U.S. trucking industry.

Sources: American Trucking Associations and its industry data summary. Figures use different definitions and reporting periods, so they should not be treated as one single-year census of the entire industry.

 

The most important point is that trucking is a large, diverse industry. It includes large national fleets, small regional carriers, independent owner-operators, specialized haulers, and companies that support freight transportation.

The figures also show that a huge industry does not guarantee strong profits for every business. Revenue can rise or fall as freight demand, fuel prices, labor costs, and truck capacity change.

1. How Much Freight Moves by Truck?

Trucks move a large share of the goods used by American businesses and households. Food, building materials, clothing, machinery, medical supplies, retail products, and many other items depend on trucking at some point in the supply chain.

According to the ATA, trucks transported 11.27 billion tons of freight in 2024. That represented approximately 72.7% of domestic freight tonnage.

 

This does not mean trucks carry every shipment from its starting point to its final destination. Railroads, ships, airplanes, and pipelines also move freight. In many cases, however, trucks connect these transportation systems.

Consider a shipment of imported products arriving at a U.S. seaport. A ship may bring the cargo into the country, but trucks often move containers to distribution centers or warehouses. Another truck may deliver the goods to a retailer. A local delivery vehicle may then take the order to a customer’s home.

Each stage depends on reliable transportation.

Why trucking is so important to supply chains

Trucking offers flexibility that many other transportation methods cannot provide on their own. Trucks can serve businesses in large cities, small towns, industrial areas, and rural communities.

They also support different shipping needs, including:

• Full truckload (FTL) shipments

• Less-than-truckload (LTL) freight

• Refrigerated food and temperature-sensitive goods

• Flatbed freight and construction materials

• Tanker transportation

• Intermodal container transport

• Local and last-mile deliveries

This range of services helps explain why trucking remains essential even when businesses use rail, air, or ocean freight for part of a shipment.

2. How Much Revenue Does the Trucking Industry Generate?

The ATA estimated that U.S. trucking generated $906 billion in gross freight revenue in 2024, compared with approximately $1.004 trillion in 2023.

 

That decline is an important reminder: the trucking industry’s size does not mean revenue always increases.

Freight revenue can change with shipment volumes, pricing, available truck capacity, and broader economic activity. A carrier may move plenty of freight but still face financial pressure if rates are too low to cover operating costs.

It is also important to understand what the revenue figure represents. The ATA’s figure covers gross freight revenue for primary shipments. It is not the same as the total economic contribution of every business connected to transportation, nor is it the profit earned by trucking companies.

Revenue is not the same as profit

Suppose a small trucking business bills customers $500,000 over a year. That number alone does not tell you whether the business is successful.

The owner still needs to pay for:

• Diesel fuel and diesel exhaust fluid

• Truck and trailer payments

• Maintenance and repairs

• Insurance

• Driver wages, if applicable

• Tolls and permits

• Dispatching and administrative services

• Taxes and other business expenses

After those expenses, the amount remaining may be much smaller than the gross revenue suggests.

For owner-operators, this distinction is especially important. A truck that generates substantial revenue can still struggle if it runs too many empty miles, spends too much time waiting, or requires frequent repairs.

Practical takeaway: Track revenue and expenses separately. Calculate your operating cost per mile and review the profit from each load or trip, rather than judging performance by gross revenue alone.

3. How Many People Work in the Trucking Industry?

Trucking supports a large workforce. The ATA reported that trucking-related jobs accounted for approximately 8.4 million people in 2024, including 3.58 million professional drivers.

 

These figures cover a broader industry than tractor-trailer drivers alone. Trucking also depends on dispatchers, mechanics, safety personnel, warehouse workers, logistics coordinators, fleet managers, and administrative staff.

The U.S. Bureau of Labor Statistics (BLS) provides a separate measure for heavy and tractor-trailer truck drivers. Its data show approximately 2.1 million workers in this occupation in May 2025.

 

Why is this number lower than the ATA’s professional-driver estimate? The sources use different methods and definitions. They should not be treated as interchangeable counts.

What does this mean for truck drivers?

The trucking workforce supports a wide range of career paths. Drivers may work for large fleets, regional carriers, private companies, or small trucking businesses. Some eventually become owner-operators and take on the responsibility of running their own operations.

The BLS projects about 214,500 openings per year, on average, for heavy and tractor-trailer truck drivers from 2025 through 2035. Many openings are expected to come from workers leaving the occupation or retiring, rather than from employment growth alone.

 

These are national projections, not a guarantee of employment or pay in every state. Opportunities vary with experience, location, freight type, employer needs, and qualifications.

4. How Many Trucking Companies Are in the United States?

The U.S. trucking industry includes businesses of many sizes. Some operate thousands of trucks across the country. Others have a handful of power units and serve a specific region or type of freight.

According to the ATA’s industry data, nearly 580,000 active U.S. motor carriers registered with FMCSA owned or leased at least one tractor as of June 2025. Of these carriers, 91.5% operated 10 or fewer trucks, while 99.3% operated fewer than 100 power units.

 

These figures highlight an important fact: the trucking industry is largely made up of small businesses.

Small carriers play a major role

Smaller carriers may focus on regional freight, specialized equipment, local customers, or particular shipping lanes. Their size can allow them to provide personal service and respond quickly to customer needs.

However, smaller businesses can also face challenges. They may have less purchasing power, fewer backup trucks, limited administrative support, and less room to absorb unexpected expenses.

For example, if a single-truck owner-operator experiences a major engine failure, the truck may stop earning revenue while repair bills continue. A larger fleet may have other trucks available to keep some deliveries moving.

Small trucking businesses can manage these risks by maintaining cash reserves, scheduling preventive maintenance, building reliable customer relationships, and tracking costs closely.

5. What Types of Businesses Make Up the Trucking Industry?

Trucking is not one single type of business. Different segments serve different customers and require different equipment, skills, and operating strategies.

For-hire trucking companies

For-hire carriers transport freight for customers in exchange for payment. They may work with manufacturers, retailers, freight brokers, third-party logistics providers, and other businesses.

Some specialize in full truckload freight. Others focus on LTL shipments, regional delivery, or specialized transportation.

Private fleets

Private fleets transport goods for the company that owns or operates them. A grocery chain, manufacturer, or retailer may operate trucks to move its own products between facilities and customers.

Private fleets have different business priorities from for-hire carriers because transportation is often part of a larger business operation.

Owner-operators

Owner-operators own or lease their trucks and operate as independent businesses or work under a carrier’s authority, depending on their arrangement.

They must manage more than driving. Their responsibilities can include choosing loads, controlling expenses, maintaining equipment, arranging insurance, handling paperwork, and planning for taxes.

Freight brokers and dispatch services

Freight brokers help connect shippers with carriers. Dispatch services may help carriers or owner-operators find loads, communicate with brokers, organize schedules, and handle paperwork, depending on the service agreement.

These businesses are part of the broader freight ecosystem, although their revenue should not automatically be added to trucking freight revenue without checking how the figures are defined.

6. What Drives the Size of the Trucking Industry?

The trucking industry grows or contracts alongside the businesses and consumers that need goods moved.

Several factors influence its size and performance.

Consumer spending and retail demand

When people buy more products, retailers and suppliers often need to move more inventory. Trucks transport goods to warehouses, distribution centers, stores, and homes.

Changes in consumer spending can therefore affect freight demand.

Manufacturing and construction

Factories need raw materials and components. Construction businesses need lumber, steel, concrete, machinery, and other supplies.

When manufacturing or construction activity changes, freight volumes can change too. The effect depends on the types of goods involved and where they are produced or used.

E-commerce and distribution networks

Online shopping creates demand for transportation at multiple stages. Products may travel from manufacturers to warehouses, between distribution centers, and then to local delivery facilities.

Fast delivery expectations also place pressure on logistics companies to coordinate inventory, transportation, and delivery schedules efficiently.

Cross-border trade

Trucks are important to trade with Canada and Mexico. The ATA reported that trucks transported 67% of the value of U.S.-Canada surface trade and 85% of U.S.-Mexico surface trade in 2024.

 

These percentages refer to the value of surface trade, not the share of all international trade by every transportation method.

Changes in trade policy, border processing, manufacturing locations, or demand for imported goods can influence cross-border trucking.

7. What Challenges Does a Large Trucking Industry Face?

A large industry can still be difficult to operate in. Trucking businesses must balance revenue against costs and changing market conditions.

Common challenges include:

• Fuel costs: Diesel price changes can quickly affect operating expenses.

• Freight rate pressure: Strong competition may make it harder for some carriers to secure rates that cover costs.

• Maintenance: Repairs, tires, and replacement parts can create unexpected bills.

• Insurance: Premiums and coverage requirements can place pressure on operating budgets.

• Regulatory compliance: Carriers must follow the rules that apply to their operations.

• Driver recruitment and retention: Employers need to offer workable schedules, fair compensation, and safe equipment.

• Empty miles and delays: Deadhead travel, congestion, and long loading or unloading times can reduce productivity.

The right response depends on the business. A small carrier may focus on cost control and customer relationships, while a larger fleet may invest in route planning, maintenance systems, and performance reporting.

8. What Does the Size of the Trucking Industry Mean for Owner-Operators?

The size of the market creates opportunities, but it does not guarantee success for every operator.

A large freight network offers many potential customers, equipment types, and lanes. At the same time, competition can be intense, and market conditions vary widely.

Owner-operators should focus on building a business that can handle changing conditions.

Choose freight based on profitability

Do not select loads based only on the gross rate. Consider total mileage, deadhead miles, fuel consumption, tolls, delivery appointments, and the likelihood of finding a return load.

A slightly lower-paying load may be more profitable if it reduces empty miles and positions the truck in a stronger freight market.

Build reliable customer relationships

Consistent customers can help make planning easier. Strong communication, dependable service, accurate paperwork, and on-time performance can support repeat business.

Avoid relying entirely on one customer or one freight source if that leaves the business exposed to sudden changes.

Use dispatch support where it makes sense

A dispatcher may help with load searches, broker communication, rate discussions, and trip planning. Before hiring a service, understand the fees, responsibilities, contract terms, and level of support offered.

You can learn more about what a truck dispatcher does and explore truck dispatching services.

Keep business records

Track revenue, expenses, maintenance, fuel, and miles. These records help you see which lanes and customers perform well and which ones need a different approach.

The goal is not simply to participate in a large industry. It is to operate a business that can earn a sustainable return.

9. Where to Find Reliable Trucking Industry Statistics

Industry statistics can help with business planning, research, and content creation. However, figures should always be checked for their definitions and reporting dates.

Use these sources:

• American Trucking Associations: Trucking revenue, tonnage, employment, carrier counts, and other industry indicators.

• U.S. Bureau of Labor Statistics: Driver employment, wages, and occupational projections.

• Federal Motor Carrier Safety Administration: Motor carrier safety and regulatory information.

• U.S. Department of Transportation: Transportation programs, policy, and infrastructure information.

Before publishing a statistic, check the year, population covered, and measurement used. For example, the number of registered carriers is not the same as the number of trucks on the road, and industry revenue is not the same as profit.
