Why was my MC revoked?
Most MC revocations stem from one of five triggers: insurance lapse over 30 days, BOC-3 lapse, missed biennial MCS-150 update, failed new-entrant safety audit (under 18 months), or an Unsatisfactory safety rating. The FMCSA Federal Register revocation notice lists the specific cause. Each cause has a different reinstatement path.
The most common revocation is insurance lapse. FMCSA cancels operating authority 30 days after insurance lapses if no replacement coverage is filed. The reinstatement path is straightforward: bind new insurance, file BMC-91X, MC reactivates within 24 hours.
BOC-3 lapse can also trigger revocation, though less commonly than insurance. If the BOC-3 process-agent provider closes shop or the carrier changes name without re-filing, FMCSA can revoke after the carrier fails to cure within 30 days.
A missed biennial MCS-150 update puts the USDOT into Inactive status, which functionally voids the MC even though the MC remains technically "issued." Reactivation requires filing the missed MCS-150.
New-entrant safety audit failure (within the first 18 months of operation) triggers revocation if the carrier does not respond to the corrective notice within the cure window. Reinstatement requires submitting and passing a corrective audit.
An Unsatisfactory safety rating (separate from new-entrant audit) gives the carrier 60 days to upgrade to Conditional or Satisfactory or face automatic revocation. Reinstatement requires a Corrective Action Plan plus an FMCSA upgrade audit.
