Getting a DOT number in Maryland
Interstate carriers in Maryland register with FMCSA for a USDOT number, plus MC authority if they haul regulated freight for hire. Many states also require a USDOT number for intrastate commercial vehicles, so check with the Maryland transportation or motor vehicle agency for intrastate rules.
