August 7, 2025 | Winters | Truck Accident
Millions of commercial trucks operate across the countless roads and highways of the U.S. each day. The problem, however, is that tens of thousands of truck accidents happen annually across the country, with many of these wrecks leaving others killed or significantly wounded.
The more vehicles a company has on the road, the more likely it is that one of its trucks will be involved in one of these accidents. Florida sees no shortage of commercial trucking, as the state plays a critical role in the nation’s interstate commerce system.
That’s why it’s crucial not only to know which trucking companies pose the most significant risk, but also to understand when to contact a qualified truck accident attorney if you’re ever involved in a collision with a commercial vehicle.
Top 10 U.S. Trucking Fleets
Over one million trucking companies own and operate commercial vehicles, but each company’s fleet size can vary widely.
To that end, the companies with the ten largest U.S.-based fleets are as follows:
1. FedEx
The Federal Express Corporation operates over 138,000 powered vehicle units, including large commercial trucks.
2. UPS
Along with FedEx, the United Parcel Service has one of the largest vehicle fleets in the country, with roughly 117,000 total units owned and operated by the company.
3. J.B. Hunt Transport, Inc.
J.B. Hunt is yet another large national freight company. Although its fleet is not as immense as UPS or FedEx, more than 25,000 powered vehicle units are nevertheless registered to the company.
4. Swift Transportation Co.
Although based in Phoenix, AZ, Swift-owned cabs and trailers can still be easily found on highways throughout Florida and the rest of the country, as the company owns a fleet of approximately 13,000 powered units.
If you are dealing with going up against a national carrier and its insurer, it is worth getting a professional read on it before the problem gets more expensive.5. Old Dominion Freight Line
Though it may ultimately call North Carolina home, Old Dominion Freight Line’s green trucks can be found hauling trailers across the country. A recent report found the company’s fleet size to be greater than 10,000 units in total.
6. XPO Logistics
Headquartered in Ann Arbor, Michigan, XPO Logistics recently reported having just under 10,000 powered vehicle units in its fleet.
7. Schneider National
Distinguishable by its bright orange trailers and cabs that are often orange, black, or white, Schneider National has a fleet of about 9,950 vehicles.
8. Werner Enterprises
Trucks and trailers bearing the Werner name are a common sight on interstates, seeing as the company’s truck fleet consists of about 9,800 vehicles.
9. Estes Express Lines
You might see black and yellow Estes Express cabs pulling single or double trailers as they move freight across the country; like the last few companies, it has a 9,000-plus vehicle fleet.
10. U.S. Xpress, Inc.
Although it may be the smallest freight hauler on the list, U.S. Xpress still has more than 5,700 vehicles in its fleet to support the company’s national operations.
What America’s Largest Trucking Companies Have in Common—and Why It Matters
Each of these ten commercial carriers differs from the next in many ways.
Some of the various characteristics that distinguish one company from another include the following:
- Its fleet size and number of drivers
- The location of its headquarters
- The territories in which its trucks are most frequently seen
- The number of crashes in which their drivers and vehicles are involved
Nonetheless, the common thread between all of these companies is that the people who work for them are capable of committing careless mistakes while going about their jobs. These errors and lapses in judgment can, in turn, lead to severe or fatal truck crashes that cause thousands of dollars or more in damages for those affected by them.
