What Is Motor Carrier in Trucking?
Also called: Carrier, For-Hire Motor Carrier, Private Motor Carrier
A motor carrier is a person or company that moves goods or passengers by commercial motor vehicle. Federal safety rules say a motor carrier is either a for-hire carrier or a private carrier. A for-hire carrier is paid to haul. A private carrier moves its own goods. The term also covers the carrier's agents and officers, including employees who dispatch drivers (49 CFR 390.5T).

Key Points
- 49 CFR 390.5T says a motor carrier is a for-hire motor carrier or a private motor carrier
- A for-hire motor carrier is a person who moves goods or passengers for pay (49 CFR 390.5T)
- A private motor carrier moves property or passengers by commercial motor vehicle and is not a for-hire carrier. A business that hauls its own products is an example (49 CFR 390.5T)
- The safety rules count the carrier's agents and officers as part of the carrier. So are employees who hire, train or dispatch drivers, and those who maintain equipment (49 CFR 390.5T)
- For the safety rules, the term also covers an employer and an exempt motor carrier (49 CFR 390.5T)
- The transportation law agrees: a motor carrier provides transportation by motor vehicle for pay (49 U.S.C. 13102(14))
- A broker is not a motor carrier. Under the law, a broker is a person, other than a motor carrier or its employee or agent, that arranges transportation by motor carrier for pay (49 U.S.C. 13102(2))
What is a motor carrier?
A motor carrier is the company responsible for moving freight or passengers by truck or bus. The federal safety rules define it in 49 CFR 390.5T as a for-hire motor carrier or a private motor carrier. The transportation law, 49 U.S.C. 13102(14), says a motor carrier is a person providing motor vehicle transportation for compensation. Both mean the same thing. The carrier runs the trucks and answers to FMCSA for safety.
What is the difference between a for-hire and a private motor carrier?
A for-hire motor carrier is paid to move other people's goods or passengers. An owner-operator who hauls freight for brokers and shippers is a for-hire carrier. A private motor carrier moves its own property by commercial motor vehicle and is not a for-hire carrier (49 CFR 390.5T). A grocery chain that runs its own trucks to its own stores is a private carrier. Both kinds must follow the federal safety rules. The rules for operating authority apply to for-hire carriers.
Is a dispatcher a motor carrier?
A dispatch company does not haul freight. So it is not a carrier by that act alone. But the safety rules treat the people who dispatch a carrier's drivers as part of the carrier. The definition in 49 CFR 390.5T includes the carrier's agents, officers and representatives. It also includes the employees responsible for hiring, supervising, training, assigning or dispatching drivers. The carrier stays responsible for following the safety rules. A carrier that uses an outside dispatcher should keep its own records and its own control over safety. This page is general information, not legal advice.
Is a motor carrier the same as a freight broker?
No. A motor carrier hauls the freight. A broker arranges for someone else to haul it. The law defines a broker as a person, other than a motor carrier or an employee or agent of a motor carrier, that sells or arranges transportation by motor carrier for compensation (49 U.S.C. 13102(2)). A company can hold both kinds of authority, but the two jobs are different, and each has its own filing and bond rules. See the freight broker and double brokering terms for more.
Does a motor carrier need a motor carrier number?
It depends on what the carrier does. A carrier that runs a commercial motor vehicle in interstate commerce needs a USDOT number, which identifies it to FMCSA for safety. A for-hire carrier that hauls regulated freight for pay across state lines also needs operating authority, which carries an MC number. A private carrier hauling its own goods generally does not. Our USDOT number, MC number and operating authority terms explain each filing.
