The launch sequence
Federal first, then Maryland. The federal side is identical in every state and is covered in depth by how to get your own authority; the state facts below come from our sourced Maryland data.
- Register with FMCSA and claim the Maryland designation. All DOT numbers, interstate and intrastate, are issued online through the FMCSA registration portal. A carrier that will stay inside Maryland obtains the Maryland USDOT Number there; there is no state application and no published state fee.
- Mark the trucks. Carrier name or trade name plus the identification number preceded by the letters USDOT, on both sides of every truck, tractor and bus. Non-compliance brings fines, so the marking is the state's enforcement surface for the whole regime.
- Sort the insurance before registration. The MVA requires proof of Maryland insurance to register a vehicle, and the incorporated federal schedule governs where it applies in full. Ask your insurer what Maryland needs before the titling appointment, not during it.
- Title the vehicles in Maryland, then apportion. Titling transactions must complete before apportioned registration issues. Open the myMVA Business Portal, register for IRP, and bring the proof-of-identity set and heavy vehicle use tax proof for the heaviest units.
- License for IFTA with the Comptroller. If qualified vehicles run in two or more member jurisdictions, license through Motor Carrier Connect with your federal employer identification number. The license and the decals cost nothing; the quarterly returns are where the money is.
- Open a Maryland One account if any load runs big or heavy. Oversize and overweight permits, routing and the exceptional and commodity permits all live in Maryland One with the SHA Hauling Permit Unit. Superload moves need engineering review ahead of the move date.
- Calendar the recurring deadlines. Quarterly IFTA returns are due the month after each quarter closes, apportioned credentials must be displayed by the end of the expiration month with enforcement the first of the next, and the federal registration behind the Maryland number carries its own biennial update. Put all three in one calendar.
The order that works in Maryland
Federal first. Register with FMCSA and, if the operation stays inside Maryland, say so: the number you receive carries the Maryland intrastate designation that satisfies the state requirement. Interstate for-hire carriers add federal operating authority and its insurance filings on top of the same number.
Then the state layer, which is lighter here than in most states. Display the number and your carrier name on both sides of every truck, tractor and bus; Maryland enforces the marking rule with fines. Title and register the vehicles with the MVA, showing Maryland insurance proof. If you run interstate, apportion through the MVA's business portal, and license for IFTA with the Comptroller so one quarterly return covers your fuel tax everywhere you run.
Permits come last, and only if your loads need them. Oversize or overweight work means a Maryland One account and the SHA Hauling Permit Unit, with route rules attached to each move rather than to your company.
Where Maryland differs from other states
Maryland skipped the state authority model that neighbors use. No state freight application exists, no state carrier number besides the federal one, and no fee published for the intrastate identification number. The tradeoff is enforcement through marking and roadside checks rather than a certificate in a binder.
Two more state habits shape daily operations. Maryland does not collect the Unified Carrier Registration itself, so interstate carriers register through the national system and find no state office to call. And the rulebook carries rules you can trip on without ever loading a truck: a five-minute idling limit and a diesel opacity program that applies to any diesel vehicle on a Maryland highway.
The Maryland facts you will need
- State agency
- Maryland Department of Transportation State Highway Administration, Motor Carrier Division (intrastate motor carrier identification numbers); Maryland Public Service Commission, Transportation Division (intrastate for-hire passenger permits)
- State filing fee
- No Maryland state fee for the intrastate identification number is published on the SHA Maryland DOT Numbers page or in the Motor Carrier Handbook, so none is recorded. The Handbook notes FMCSA charges a fee for the interstate MC Number (operating authority), which is a different credential; the Maryland page describing the intrastate number names no fee.
The complete tables live on the dedicated pages: intrastate authority, IRP registration, IFTA, and trucking permits.
Budget the launch before you file
The trucking startup cost calculator builds a line-item estimate from the sourced fee data, and the cost pillar explains every line. Neither replaces a quote for your truck and insurance, which are the two biggest variables.
Common mistakes when launching in Maryland
Hunting for a Maryland freight authority application
There is none. Maryland issues no intrastate operating authority for freight, and carriers waste weeks looking for a state form. The state requirement is the Maryland USDOT Number through FMCSA plus the display duty.
Treating no authority as no obligation
The absence of a state authority program does not exempt anyone from the identification-number regime. Every registered truck over the published line, tractor and bus carries the number and the carrier name on both sides, and the state enforces it with fines.
Adding a passenger shuttle without a PSC permit
Any motor vehicle transporting passengers for hire within Maryland needs a Public Service Commission permit. A freight carrier that adds a van or a shuttle has entered a different regime without changing weight class.
Waiting for a Maryland UCR invoice
Maryland does not participate in the Unified Carrier Registration Act and there is no state UCR office. Interstate Maryland carriers still owe UCR and must register through the national system themselves.
Booking the heaviest loads across a weekend
The Maryland Transportation Authority bars permit movements on its toll facilities from midday Friday until Monday morning, the widest loads face weekday midday windows, and holiday moratoria stop moves entirely on set dates. Check the facility and holiday sheets before promising a delivery date.
Requesting an overweight permit without max registration and enough axles
The Handbook conditions overweight hauling permits on maximum weight registration and a minimum axle count, and a Maryland-registered vehicle must be registered for the maximum permissible gross weight. Sort registration before the permit application, not after the rejection.
Letting IFTA returns slide because the license was free
The free license carries real teeth: late filing draws a percentage penalty with a flat minimum, non-filing invites an assessment on a standard miles-per-gallon fallback, delinquency can require a bond, and the license can be revoked after notice and hearing.
