Short answer
A freight broker arranges truck transportation between a shipper that has freight and a motor carrier that has a truck. The broker doesn’t own the freight and doesn’t haul it. Federal law requires broker authority from FMCSA and a $75,000 bond or trust fund. The broker’s pay is the difference between what the shipper pays and what the carrier is paid.
A shipper with ten loads a week and no trucks has two choices. It can build relationships with enough carriers to cover every lane, or it can call a broker who already has them. A carrier with an empty truck in Laredo faces the same choice from the other side. The broker sits between the two and gets the load covered.
This post covers the legal definition, what a broker does on a load from quote to invoice, how the money works, and how a broker differs from a carrier, a forwarder, an agent and a dispatcher.
The legal definition of a freight broker
Federal law defines the job in 49 U.S.C. 13102. A broker is “a person, other than a motor carrier or an employee or agent of a motor carrier, that as a principal or agent sells, offers for sale, negotiates for, or holds itself out by solicitation, advertisement, or otherwise as selling, providing, or arranging for, transportation by motor carrier for compensation.”
FMCSA’s regulation says the same thing in fewer words. Under 49 CFR 371.2, a broker is “a person who, for compensation, arranges, or offers to arrange, the transportation of property by an authorized motor carrier.”
Two things follow from that wording. A broker arranges and a carrier hauls, so the broker never takes possession of the freight. And a trucking company that accepts a load and then hands it to another carrier is arranging transportation, which is brokering. That takes broker authority. Without it, the handoff is double brokering. One company can hold both authorities, and we cover how in can a freight broker own trucks.
What a freight broker does on a load
Every load runs through the same six jobs, whether the brokerage has two people or two hundred.
Quote the shipper
The shipper asks for a price on a lane. The broker prices it from the current spot rate, its own history on that lane, and what it expects to pay a truck.
Build the load
Once the shipper sends the load tender, the broker enters the pickup and delivery addresses, appointment times, commodity, weight and equipment type. Mistakes made here follow the load all the way to the invoice.
Find and vet a carrier
The broker posts the load or calls carriers it knows, then checks the carrier’s authority, insurance and safety record before booking. Our carrier onboarding guide covers the checks, and the freight fraud guide covers what happens when they get skipped.
Send the rate confirmation
The rate confirmation is the agreement for that one load: the rate, the stops, the appointments, and the rules on detention and other extras. The carrier signs it before the truck rolls.
Track the truck
From dispatch to delivery the broker keeps the shipper informed, by check call or by tracking from the driver’s phone or ELD. When something slips, the broker is the one who calls the receiver.
Collect the paperwork, bill and pay
After delivery the broker collects the signed bill of lading as proof of delivery, invoices the shipper, and pays the carrier.
How a freight broker gets paid
A broker earns the spread. If the shipper pays $2,000 for a load and the broker pays the carrier $1,700, the broker’s gross margin is $300, or 15 percent.
That example is close to what the industry reports. In the Transportation Intermediaries Association’s member survey for the fourth quarter of 2024, the average truckload invoice was $1,920 and the gross margin per load was $290, which TIA reported as 15.3 percent (TIA 3PL Market Report, Q4 2024). RXO, one of the largest brokers in the country, reported a truck brokerage gross margin of 13.3 percent for 2025 in its year-end earnings release.
Gross margin is what’s left before the brokerage pays anyone. Salaries, commissions, software, the bond, insurance and the loads that go wrong all come out of that $290.
The two invoices also run on separate clocks. If the shipper pays in 45 days and the carrier wants its money in 30, the broker carries the difference. A carrier that can’t wait may sell its invoice through freight factoring, and then the broker pays the factor. For what individual brokers and agents take home, see how much freight brokers make.
Freight broker vs. carrier, forwarder, agent and dispatcher
These five get mixed up all the time. What separates them is who touches the freight and who answers for it.
| Role | What they do | Who they work for | Cargo liability |
|---|---|---|---|
| Freight broker | Arranges the truck. Never takes possession of the freight | The shipper is the customer. The broker hires the carrier | None under the federal definition. FMCSA describes brokers as not assuming responsibility for the cargo. A contract can change that |
| Motor carrier | Hauls the freight in trucks it operates | Whoever hired it, a shipper or a broker | Liable for loss and damage under 49 U.S.C. 14706 |
| Freight forwarder | Assembles and consolidates shipments and takes responsibility for the move from receipt to destination, using carriers for the hauling | The shipper | Treated as a carrier. The statute calls the forwarder “both the receiving and delivering carrier” |
| Freight agent | Sells and covers loads under a broker’s authority and bond | A broker, usually on commission | Runs through the broker |
| Truck dispatcher | Finds loads and handles paperwork for a trucking company | The carrier | Runs through the carrier |

What it takes to be a legal freight broker
There’s no exam. A broker needs four things on file.
- Broker authority from FMCSA, which comes with an MC number.
- A $75,000 surety bond or trust fund, required by 49 CFR 387.307. Our broker bond entry explains the two forms.
- A process agent filing, the BOC-3.
- Unified Carrier Registration every year. Brokers pay the lowest bracket, $46 for 2026 and $55 for 2027. Our UCR registration guide has the full fee table.
Insurance is a separate question. Federal rules don’t require a broker to carry any, and shipper contracts usually ask for it. We cover that in freight broker insurance.
Brokering without authority is expensive. 49 U.S.C. 14916 sets a civil penalty of up to $10,000 for each violation and makes the person liable to anyone harmed. The setup steps are in how to become a freight broker and how to start a freight brokerage.
The records a broker has to keep, and who can see them
49 CFR 371.3 requires a broker to keep a record of every transaction for three years. The record has to show:
- the consignor’s name and address
- the originating carrier’s name, address and registration number
- the bill of lading or freight bill number
- what the broker was paid for the brokerage service, and by whom
- any non-brokerage service, what was charged for it, and who paid
- any freight charges the broker collected, and the date it paid the carrier
The same rule gives each party to a brokered load the right to review that record. FMCSA proposed in November 2024 to tighten it, with electronic records and a 48-hour deadline to hand them over. As of early October 2026, no final rule has been published.
In practice that record is the load file. A TMS that ties the rate confirmation, the carrier, the paperwork and both invoices to one load makes the record easy to produce when someone asks.
How big freight brokerage is
FMCSA listed about 25,000 active broker authorities in spring 2026. We broke that number down in how many freight brokers are in the US.
By revenue, Armstrong & Associates put U.S. domestic transportation management at $128.3 billion in gross revenue for 2025 (Armstrong, June 2026). That category is wider than truck brokerage. It also counts managed transportation, intermodal and last-mile work.
Brokers still handle a minority of truckload freight. RXO told investors in a 2022 SEC filing that broker penetration of for-hire truckload was “still less than 25%”, based on 2021 figures. That’s one company’s estimate and it’s a few years old. We haven’t found a newer published figure.
When a shipper should use a broker, and when to go direct
A broker earns its margin on freight that’s hard to plan: lanes you ship a few times a month, a surge that outruns your regular carriers, or equipment you rarely need. The broker already knows who runs that lane and has already vetted them.
Go direct when the freight is steady. If you ship the same lane every day, a carrier can commit trucks to it under contract and you keep the broker’s margin.
Before you hand a broker a load, check four things:
- Its authority and bond are active. FMCSA’s public records show both.
- Your contract says who handles a cargo claim and how.
- It can tell you how it vets carriers, in specifics.
- It will name the carrier on your load before pickup.
Where FreightVero fits
FreightVero is a TMS for freight brokers. Loads, carriers, rate cons, tracking and billing live in one place, and a load can’t move to the next stage until the proof behind it is on file. It was built with Bronco Logistics, a working brokerage.
Final thoughts
A freight broker sells one thing: a truck that shows up, run by a carrier somebody checked. The law around the job is short. Get the authority, post the bond, keep the records, and don’t present yourself as the carrier. The work is the six steps above, done right on every load.
