Ask ten people what a truck dispatcher does and the answers will differ. For some it is the person at a carrier who assigns loads to drivers. For others it is an outside service that finds freight for owner-operators, or the operations desk at a broker. Federal law does not define the word. What it does define is who answers for what a driver does behind the wheel, and a dispatcher's decisions sit inside that. This guide looks at where the rules reach dispatching, using the text of the regulations.
A Job Title, Not a Legal Category
The statute that defines the parties to a shipment, 49 U.S.C. 13102, defines motor carriers, brokers and freight forwarders. It does not define a dispatcher. The safety regulations come at it from the other side. In 49 CFR 390.5, the term "motor carrier" includes the carrier's agents, officers and representatives, and employees responsible for hiring, supervising, training, assigning, or dispatching of drivers. So a dispatcher who works for a carrier is not a separate regulated party. The carrier's duties under the safety rules reach the dispatcher's decisions.
An outside business that finds loads for a carrier or an owner-operator is a different question. Whether it counts as a broker depends on what it does, under the statute's definition of arranging transportation for compensation. What Is a Freight Broker? The Legal Definition and Requirements sets that out.
Four Rules That Reach a Dispatch Decision
| Rule | What it says | Where a dispatcher meets it |
|---|---|---|
| 49 CFR 390.11 | Wherever a duty or prohibition is placed on the driver, the motor carrier must require observance of it. | The carrier cannot treat a driver's limit as the driver's problem alone. |
| 49 CFR 395.3(a) | No motor carrier may permit or require a driver to drive beyond the hours-of-service limits. | Assigning a load plan that cannot be driven within 11 driving hours and the 14-hour window. |
| 49 CFR 392.3 | A motor carrier may not require or permit a driver to operate while alertness is impaired, or likely to become impaired, by fatigue, illness or any other cause. A narrow exception covers grave emergency. | Pushing a tired driver to finish "one more" delivery. |
| 49 CFR 390.6 | A motor carrier, shipper, receiver or transportation intermediary, and their agents, may not coerce a driver to operate in violation of the listed parts. A driver can file a written complaint under 386.12(c). | Threatening a driver's loads or pay if the driver refuses an illegal run. |
The coercion rule is worth reading closely, because it is not limited to carriers. It names shippers, receivers and transportation intermediaries too, and it describes the complaint process: the driver's written complaint must describe the action the driver claims was coercion and identify the regulation the driver was coerced to violate.
Can the Day's Loads Be Run? A Check
Take a made-up plan. A driver comes on duty at 06:00 after 10 consecutive hours off. The dispatcher lines up three loads that add up to 640 driving miles. At an average of 55 mph, 640 ÷ 55 is about 11.6 hours of driving. The limit is 11 hours of driving within the 14-hour window (49 CFR 395.3(a)), so the plan cannot be completed in one duty period, before counting a minute of loading or waiting.
There are three honest ways out. Cut the plan to what fits, which at 55 mph is 11 × 55 = 605 miles. Move the last load to the next duty period after the driver's required off-duty time. Or hand the last load to another driver. The rule limits hours, not miles, so a plan that works at one average speed can fail at another. Hours of Service for Truck Drivers: The Limits and Their Exceptions has the full set of limits and exceptions.
Is a Dispatch Service the Same as a Broker?
Not necessarily, and the label does not decide it. The statute defines a broker as someone, other than a motor carrier or its employee or agent, that sells, negotiates for, or arranges transportation by motor carrier for compensation. A dispatch service that works as a carrier's agent, performing duties under the carrier's direction, is in a different position from one that arranges loads on its own account. Because that depends on the facts and the contract, anyone hiring or operating such a service should read the definition and ask for the arrangement in writing, rather than relying on the name of the service.
What This Guide Leaves Out
It gives no pay figure for dispatchers, because the federal sources used here do not publish one. It also does not cover the load boards where dispatch services often find freight, which Load Boards: How to Vet a Load Before You Book It covers, or the broader questions of contract and liability between a carrier and a dispatch service.
