The top 10 trucking companies in the USA control a significant share of freight movement, operating tens of thousands of commercial vehicles on American highways every day. According to the American Trucking Associations, trucks transported more than 11 billion tons of freight in the United States in 2024, and that volume continues to grow. The biggest trucking company in the US, UPS, generates over $90 billion in annual revenue.
The legal reality is that large trucking companies have dedicated legal teams, insurers, and risk managers whose job is to limit what they pay after an accident.
Why the Size of a Trucking Company Matters After an Accident
When a commercial truck causes a crash, the carrier behind that vehicle shapes how the truck accident claim is handled. A regional trucking company with a small fleet operates differently from a national carrier running 20,000 trucks across interstate corridors.
Larger carriers typically maintain higher liability insurance limits under 49 CFR Part 387 and maintain sophisticated legal and claims departments to manage accident exposure at scale.
That size advantage does not work in the injured victim’s favor. It is a reason to have experienced legal representation before speaking with the carrier or its insurer.
The 10 Largest Trucking Companies in the USA in 2026
1. UPS
UPS is the largest transportation and logistics company in the United States by revenue, generating approximately $91 billion annually. Its ground fleet alone includes roughly 19,000 tractors, and UPS handles billions of parcel deliveries each year across all 50 states.
A large in-house legal and risk management infrastructure handles accidents involving UPS vehicles.
2. FedEx
FedEx operates the largest physical truck fleet among U.S. carriers, with approximately 38,000 tractors, and generates around $87 billion in revenue. Its FedEx Freight division is one of the dominant national LTL carriers.
FedEx is also one of the most frequently named defendants in commercial vehicle accident litigation.
3. J.B. Hunt Transport Services
J.B. Hunt runs approximately 20,000 tractors and generates around $12 billion in annual revenue, making it one of the most recognizable names in long-haul truckload and intermodal freight. It operates dedicated contract fleets for major retailers and manufacturers across the country.
4. Knight-Swift Transportation
Knight-Swift is the largest dedicated full truckload carrier in North America by fleet size, operating approximately 21,000 tractors and generating around $7 billion in revenue. The company was formed through the 2017 merger of Knight Transportation and Swift Transportation.
Drivers and victims who remember Swift Transportation as a separate carrier now deal with Knight-Swift’s combined legal and insurance operation.
5. XPO
XPO generates approximately $8 billion in revenue and focuses primarily on LTL freight and heavy-haul transportation. Following its split from GXO Logistics, XPO operates as a standalone freight carrier with a significant presence on major freight corridors.
6. Old Dominion Freight Line
Old Dominion generates approximately $5.9 billion in revenue and is consistently ranked among the highest-performing LTL carriers based on on-time delivery and claims ratios. Its network of regional terminals covers all major U.S. markets.
7. Schneider National
Schneider National generates approximately $5.5 billion in revenue and runs around 14,500 tractors across truckload, intermodal, and bulk tanker operations. It is one of the oldest and most established carriers in U.S. trucking, with operations dating to 1935.
8. Landstar System
Landstar operates differently from most large carriers. Rather than owning a large company fleet, Landstar uses a network of independent owner-operators who haul freight under the Landstar brand.
This structure creates specific liability questions when accidents occur, since whether a driver is an employee or an independent contractor affects which insurance applies and who bears legal responsibility.
9. Werner Enterprises
Werner Enterprises generates approximately $3 billion in revenue and specializes in dedicated truckload fleets serving retail and consumer goods customers. Werner operates primarily in regional and medium-to-long-haul markets across the continental United States.
10. Estes Express Lines
Estes Express Lines is the largest privately held national LTL carrier in the country, generating approximately $5 billion in revenue. Because Estes is privately held, less safety data is publicly available than for publicly traded carriers, which can affect early case investigation after an accident involving one of its vehicles.
Key Statistics About the U.S. Trucking Industry
The scale of commercial trucking in the United States directly affects the frequency and severity of truck accidents on American roads:
- Trucks carry more than 72% of U.S. freight tonnage.
- There are more than 14 million large trucks registered in the country.
- In 2023, large trucks were involved in 156,942 crashes resulting in 4,936 fatalities, according to the FMCSA Motor Carrier Safety Progress Report.
- The FMCSA’s Safety Measurement System tracks safety performance data for carriers and makes it publicly available.
That last point matters for accident victims. Every motor carrier operating in the United States has a publicly accessible safety record on the FMCSA website, including violations, out-of-service orders, crash reports, and inspection histories.
In accident cases involving large trucking companies, that record is one of the first things an attorney will examine.
What This Means If You Were Hurt in a Crash Involving a Large Carrier
Every trucking company on this list moves faster than most victims realize when an accident happens. Their claims teams open files, adjusters contact witnesses, and preservation holds on electronic data get managed in ways that benefit the carrier. The electronic logging data, black box records, and maintenance files, most useful in a truck accident case, is all within the carrier’s control in the hours and days after a crash.
These carriers are not small operations that settle quickly to avoid headaches. They are multi-billion-dollar companies with institutional knowledge of how to manage accident exposure. An injured victim who calls without legal representation gets a very different response than an attorney who knows what evidence exists and how to get it.
Frequently Asked Questions
Does It Matter Which Trucking Company Hit You If They Are a Huge Corporation?
Yes. Large carriers carry higher insurance limits and must maintain detailed safety and inspection records. These records can strengthen your case when handled correctly.
How Long Do You Have to File a Claim After a Truck Accident Involving a Major Carrier?
Deadlines vary by state and by claim type, so it is important to speak with an attorney as soon as possible after the accident to avoid missing a filing window. For example, if your truck accident happened in Texas, you would only have two years to file a personal injury lawsuit.
What If the Trucking Company Disputes That Their Driver Was at Fault?
Large carriers routinely contest liability after accidents, and their claims teams begin building that position immediately. An attorney can counter by requesting electronic logging data, the driver’s qualification file, maintenance records, and any prior violation history from the FMCSA Safety Measurement System. The carrier’s own records frequently contain the evidence that disputes their position.
Hurt in a Truck Accident Caused by a Large Carrier?
If a commercial vehicle from any of these carriers, or any other trucking company, caused your accident, the company’s size does not diminish your right to full compensation.
