The short answer for Maryland
Maryland Business Express coordinates entity filings and account registration, but commercial vehicle credentials remain separate.
If you haul federally regulated property for compensation in interstate commerce, the federal registration stack generally includes a USDOT number, operating authority, BOC-3 process-agent designation, accepted insurance filing, and UCR. State accounts are separate.
Interstate or intrastate?
Maryland may impose intrastate registration, permit, tax, or insurance rules in addition to federal requirements. Confirm the exact rule with Maryland State Police Commercial Vehicle Enforcement before hauling only within Maryland.
Interstate commerce
A shipment can remain interstate commerce even when your truck stays inside Maryland. Look at the cargo's fixed and persistent intent, origin, and destination.
Pure intrastate commerce
State-only work can avoid federal MC authority while still requiring a state number, permit, insurance filing, tax account, or safety registration.
Maryland authority launch sequence
- Register the business with Maryland Business Express
- Obtain EIN and open a business bank account
- Price commercial insurance before submitting authority
- Complete USDOT and MC filings with matching entity data
- Personally complete Motus identity verification
- Arrange BOC-3 and accepted insurance filings
- Register UCR for the current year
- Apply through Maryland Motor Carrier Services when IRP or IFTA thresholds apply
- Confirm intrastate rules with Maryland State Police Commercial Vehicle Enforcement
- Build driver, vehicle, maintenance, and safety files before the first load
Costs to budget
Federal authority
$300
Per authority type; USDOT registration itself is free.
Insurance
Quoted
Driver, vehicle, cargo, radius, and location control the price.
State credentials
Variable
Maryland registration, plates, permits, and taxes are separate.
Never treat an undated “all-in” number as a quote. Insurance and vehicle credentials usually create more variance than the federal filing fee.
