Largest Trucking Companies in the US
Who hauls America’s freight — and why it matters when one of their trucks causes a crash.
The US trucking industry moves over 70% of all domestic freight by weight. According to Transport Topics’ 2024 Top 100 For-Hire Carrier rankings, the largest carriers range from household names like UPS and FedEx to massive fleets like J.B. Hunt and Knight-Swift. These companies operate tens of thousands of trucks on American highways daily — and when their drivers cause crashes, the size and resources of these companies mean victims need to act fast to protect their claims.
The 10 Largest US Trucking Companies by Revenue
Size matters in trucking — and not just because bigger trucks cause bigger crashes. The largest carriers have the most sophisticated legal and insurance teams, the most data in their systems, and the most to lose when they’re held accountable. Here’s how the landscape looks based on Transport Topics’ 2024 data:
| Rank | Company | Annual Revenue | Key Operations |
|---|---|---|---|
| 1 | UPS Inc. | $91.1 billion | Package, LTL, ground freight — 19,000+ tractors |
| 2 | FedEx Corp. | $87.5 billion | LTL, express, freight — 38,000+ tractors |
| 3 | J.B. Hunt Transport | $12.8 billion | Intermodal, truckload, dedicated — 23,000 trucks |
| 4 | TFI International | $9.1 billion | LTL, truckload, parcel — 14,000+ tractors |
| 5 | XPO Inc. | $7.7 billion | LTL, freight brokerage — 9,500 tractors |
| 6 | Knight-Swift | $7.1 billion | Truckload, LTL, brokerage — 24,000+ trucks |
| 7 | Old Dominion Freight | $5.9 billion | LTL carrier — 10,700 tractors |
| 8 | Schneider National | $5.5 billion | Truckload, intermodal — 10,600 trucks |
| 9 | Landstar System | $5.3 billion | Asset-light, owner-operator model — 11,000+ owner-ops |
| 10 | Estes Express Lines | $5.1 billion | LTL, final mile — 10,000+ tractors |

How Big Companies Are Structured — and Why It Matters for Crashes
Understanding how these companies are organized matters a great deal if one of their trucks hits you. Large carriers don’t just employ truck drivers directly — they use complex structures to manage liability:
Company Drivers vs. Owner-Operators
Some carriers employ drivers directly. Others, like Landstar, use independent owner-operators who own their trucks but operate under the carrier’s authority. When an owner-operator causes a crash, the carrier may try to distance itself from responsibility by claiming the driver was a contractor, not an employee. Federal regulations and court decisions have repeatedly pushed back on this tactic — carriers that control how and when a driver operates can still be held responsible.
Insurance Towers for the Biggest Players
Giants like Amazon, FedEx, and UPS use layered “insurance towers” — a primary policy covers the first layer (often $1 million), then excess layers stack on top. Some self-insure the first $1–5 million through reserves. This structure means the money is there to compensate crash victims. Getting access to it is the challenge. The MCS-90 endorsement is a key tool that guarantees payment even if a carrier’s primary policy is disputed.
Rapid Response Teams
The moment a serious crash happens, major carriers deploy dedicated teams — investigators, adjusters, and attorneys — to the scene. Their job is to gather evidence and shape the narrative before victims can. This is one reason why preserving trucking crash evidence immediately is so critical.
The FMCSA Regulates All of Them
Every motor carrier operating in interstate commerce — from UPS down to a two-truck owner-operator — must comply with FMCSA regulations. These rules cover driver hours, vehicle maintenance, drug testing, cargo securement, and more. When big carriers violate these rules and someone gets hurt, those violations become powerful evidence of negligence.
- Hours-of-service limits — 11 hours driving within a 14-hour window
- Required ELD (electronic logging device) compliance
- Mandatory drug and alcohol testing programs
- Regular vehicle inspections and maintenance records
- Driver qualification file requirements
Carrier Types: Not All Trucking Companies Are the Same
The kind of carrier involved in your crash affects who’s responsible and what evidence exists:
Truckload (TL) Carriers
These companies move a single shipper’s freight in one trailer — think Knight-Swift or Werner Enterprises. One driver, one load, one destination. Liability chains are typically straightforward, though the driver’s hours-of-service records and the carrier’s hiring practices are always worth examining.
Less-Than-Truckload (LTL) Carriers
LTL carriers like Old Dominion and FedEx Freight combine shipments from multiple customers into one trailer. Cargo securement becomes more complex — and unsecured or improperly loaded freight is a leading cause of crashes.
Owner-Operators and Small Fleets
Thousands of small carriers with 1–10 trucks operate across Kentucky and the US. Their insurance minimums are set by federal law, but their actual coverage may be limited. Trucking accident claims involving small carriers require careful investigation of all responsible parties — including brokers who may have placed an unqualified carrier on the load.
If a commercial truck hit you in Kentucky, the carrier’s size doesn’t change your rights — but it does change the strategy. Massive carriers have sophisticated defense teams.

What Happens When One of These Companies Is Responsible?
When a large carrier’s truck causes a crash, the legal process moves differently than a standard car accident. The differences between car and truck accident cases are significant:
- Federal regulations create additional liability theories — violation of FMCSA hours-of-service rules, HOS violations, or driver qualification failures can all establish negligence.
- Multiple defendants are often involved — the driver, the carrier, the shipper, the broker, and the truck manufacturer may all share responsibility.
- Critical evidence has short retention windows — black box data can be overwritten within days. Driver logs under FMCSA rules must be retained for only 6 months.
- Insurance limits are higher — federal minimums start at $750,000, and large carriers carry far more. The money to pay your claim exists.
Frequently Asked Questions
Which is the largest trucking company in the US?
By total revenue, UPS is the largest for-hire carrier in North America at $91.1 billion annually. By truckload-specific revenue, J.B. Hunt holds the top spot. Old Dominion leads the LTL (less-than-truckload) segment by service quality metrics. Rankings shift depending on whether you measure by revenue, fleet size, or cargo type.
Can I sue a large trucking company if their driver hit me?
Yes. Under federal law and Kentucky state law, you can pursue claims against the driver, the carrier, and any other parties whose negligence contributed to the crash. Large carriers often try to limit their exposure through contractual arrangements with owner-operators, but federal regulations hold carriers responsible for how their trucks operate on public roads regardless of driver employment status in many situations.
Do big trucking companies have better insurance coverage?
Yes — and significantly so. While federal law requires a minimum of $750,000 in liability coverage for general freight carriers, the largest companies typically carry policies in the tens or hundreds of millions. Some self-insure and maintain reserves well above federal minimums. This means adequate compensation is available, but accessing it requires cutting through layers of corporate and insurance defense.
What is an owner-operator and how does it affect my claim?
An owner-operator is an independent truck driver who owns their truck and operates under a carrier’s authority. Carriers often try to use owner-operator status to avoid liability by claiming the driver was an independent contractor, not an employee. However, if the carrier controlled the driver’s routes, schedule, or operations, or if the truck displayed the carrier’s DOT number, courts frequently hold the carrier responsible regardless.
How quickly do trucking companies respond after a crash?
Large carriers deploy rapid response teams — investigators, adjusters, and attorneys — within hours of a serious crash. Their goal is to gather evidence and minimize their exposure before victims can do the same. This is why it’s critical to get legal representation as soon as possible after a truck accident. A preservation letter needs to go to the carrier immediately to prevent destruction of black box data, maintenance records, and driver logs.
