Operating Authority Guides - USDOT, MC, BOC-3
FMCSA operating authority is the regulatory permission to operate a commercial motor vehicle in interstate commerce. Two identifiers - USDOT and MC - work together: the USDOT identifies your safety record; the MC docket identifies your for-hire operating authority.
These guides cover the full authority lifecycle - from the FMCSA application through ACTIVE status, the cost components, the differences between identifiers, and the reinstatement process when authority gets revoked.
