Largest Trucking Companies in the USA: Fleet Size & Capacity Guide

Updated: June 2026

The trucking industry is the backbone of freight transportation in the United States. Trucks move more than 70% of all freight by weight, making trucking companies essential to the national economy and supply chain.

Today, the U.S. trucking industry includes over one million carriers and roughly 3.5 million professional truck drivers, transporting goods between manufacturers, warehouses, ports, and retailers across North America.

In this guide, we rank the largest trucking companies in the United States in 2026 using a combination of revenue, fleet size, and freight operations. While some companies focus primarily on parcel logistics, others specialize in truckload (TL), less-than-truckload (LTL), intermodal transportation, or supply-chain services.

Navigating these massive corporate carrier networks can be complex for individual shippers, which is why modern logistics managers utilize FreightRun to compare live freight rates using our freight quote calculator.

Top 25 Largest Trucking Companies in the USA (2026 Rankings)

The largest trucking companies in the United States dominate freight transportation across sectors such as parcel delivery, LTL shipping, truckload freight, and supply chain management. The master matrix below outlines the primary commercial freight carriers operating across the United States based on their estimated annual revenues and core operational focus.

Many of these companies operate both LTL and full truckload freight networks.

Large parcel carriers such as UPS and FedEx dominate revenue rankings, while dedicated freight carriers like Knight-Swift and J.B. Hunt handle massive truckload and intermodal volumes.

Analyzing the Industry Giants: Fleet Size vs. Revenue

Large parcel carriers such as UPS and FedEx dominate total corporate revenue rankings due to their consumer-facing package networks, while dedicated asset-heavy carriers handle massive over-the-road truckload and intermodal volumes.

Fleet size rankings differ from revenue rankings because some companies operate significantly larger physical truck assets to handle raw industrial space requirements.

Largest Truck Fleets in the United States

• FedEx: ~38,000 Approximate Tractors
• Knight-Swift Transportation: ~21,000 Approximate Tractors
• J.B. Hunt Transport Services: ~20,000 Approximate Tractors
• UPS: ~19,000 Approximate Tractors
• Schneider National: ~14,500 Approximate Tractors

While FedEx and UPS operate massive fleets of parcel-delivery vehicles, Knight-Swift and J.B. Hunt dominate the heavy over-the-road full-truckload segment.

When planning complex commercial shipments, businesses often use the FreightRun platform to calculate space requirements, assess spot-market trailer capacity, and instantly determine whether their cargo volume requires a standard LTL lane or a dedicated full-truckload carrier.

Trucking Industry Statistics in the United States (2026)

The U.S. trucking industry is one of the largest freight transportation sectors in the world, moving the majority of goods across the country every day. Recent industry data highlights the scale and economic importance of trucking in the national supply chain.

Key statistics about the U.S. trucking industry include:

• Trucks transported 11.27 billion tons of freight in the United States in 2024.
• The trucking industry generated approximately $906 billion in freight revenue, accounting for the majority of transportation revenue across all modes.
• The industry supports about 8.4 million trucking-related jobs, including drivers, logistics workers, and support personnel.
• Trucks handle roughly 67% of surface trade between the United States and Canada and about 85% of goods moving across the U.S.–Mexico border.
• More than 14 million large trucks are registered in the United States, supporting nationwide freight transportation networks.

Industry forecasts suggest that freight demand will continue growing, with truck tonnage projected to approach 14 billion tons annually by 2035 as supply chains expand and e-commerce demand increases.

Because trucking handles a large share of domestic freight, businesses across the country rely on carriers to move goods efficiently between production facilities, distribution centers, and retail locations.

Companies shipping freight often compare rates from multiple carriers to find the best option for their shipments. With FreightRun’s freight quote calculator, businesses can quickly compare LTL and full-truckload freight rates from leading trucking companies.

National and Regional Less-Than-Truckload (LTL) Networks

Less-than-truckload (LTL) carriers combine shipments from multiple customers in a single trailer, allowing businesses to ship smaller loads more efficiently without paying for unused trailer space.

Top LTL carriers in the United States include FedEx Freight, Old Dominion Freight Line, XPO, Estes Express Lines, SAIA, R+L Carriers, Averitt Express, and Southeastern Freight Lines.

These companies maintain extensive terminal networks and specialize in regional and national freight distribution. Businesses shipping smaller loads often use less-than-truckload (LTL) shipping to reduce transportation costs.

Through FreightRun’s centralized partnerships, small- to medium-sized businesses can access the same deeply discounted institutional LTL tariffs normally reserved for enterprise-volume accounts.

Freight Carrier & Selection FAQ

What is the largest trucking company in the USA?

UPS is the largest transportation and logistics company in the United States by overall revenue, generating more than $90 billion annually through its global parcel, ground, and supply chain networks.

What company operates the largest truck fleet?

FedEx and UPS operate the largest total commercial vehicle fleets in North America, while Knight-Swift Transportation handles the largest standalone long-haul tractor fleet in the full-truckload sector.

An LTL (Less-Than-Truckload) carrier transports smaller shipments from multiple customers in a single truck, allowing cargo to share trailer space and split linehaul costs. An FTL (Full Truckload) carrier dedicates an entire 48-foot or 53-foot trailer to a single customer’s shipment for direct, point-to-point transit.

How can I find the cheapest rate among the largest trucking companies?

Because individual carriers price their lanes based on real-time capacity and empty backhaul trailer volume, rates fluctuate constantly. Shippers can use FreightRun to perform a comprehensive freight quote comparison, matching their exact cargo parameters across a vast network of national and regional providers in under 60 seconds.
