Common Causes of DOT Authority Revocation
Most authority revocations come from one of four root causes: an insurance gap, a BOC-3 lapse, an unpaid civil penalty, or a downgraded safety rating. Each has a different recovery path and a different cost.
Insurance lapse is the most common - the FMCSA tracks active BMC-91 (carriers) and BMC-84/85 (brokers) certificates and revokes authority if replacement coverage is not on file when a cancellation takes effect. The cure is filing a fresh certificate; FMCSA controls the timing of reactivation.
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 is the cure; FMCSA controls the timing.
A missed MCS-150 is different: it does not revoke operating authority. A missed MCS-150 update can lead to civil penalties and deactivation of the USDOT number (49 CFR 390.19T(b)(4)); a carrier with an inactive USDOT number can't operate until the update is filed. FMCSA has temporarily suspended enforcement and USDOT inactivation for biennial updates due on or after June 1, 2026; the update is still required.
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.
