Common Causes of DOT Authority Revocation

Most authority revocations come from one of four root causes: an insurance gap, a BOC-3 lapse, a missed MCS-150, or a downgraded safety rating. Each has a different recovery path and a different cost.

Insurance lapse is by far the most common — the FMCSA tracks active BMC-91 (carriers) and BMC-84/85 (brokers) certificates and revokes authority within days of a lapse. The cure is filing a fresh certificate; authority typically reactivates within 24-48 hours.

BOC-3 lapse is the second most common — usually triggered when a process-agent provider dissolves or the carrier moves between providers without an overlap. Filing a fresh BOC-3 with a new provider activates authority within 24 hours.

MCS-150 lapse happens when the biennial deadline passes without filing. FMCSA deactivates the USDOT until the update is filed. There's no late fee, but the deactivation has to clear before the next interstate trip.

Adverse safety rating (Conditional or Unsatisfactory) is the most painful — it doesn't just revoke authority, it limits the carrier's ability to be hired. Recovery requires a full safety-management plan and an FMCSA upgrade audit. The cluster below covers each cause and the path back.
