DOT deactivation vs revocation: two different severity levels

Deactivation in detail

USDOT deactivation is tied to the USDOT number and the §390.19T biennial MCS-150 update. A missed biennial update can lead to civil penalties and deactivation of the USDOT number (49 CFR 390.19T(b)(4)). FMCSA has temporarily suspended enforcement and USDOT inactivation for biennial updates due on or after June 1, 2026; the update is still required. The biennial due month is set by the last digit of the USDOT number and the odd or even year by the next-to-last digit; the update is due by the last day of that month.

To address it, the carrier files an updated MCS-150 in FMCSA's Motus system. Filing with FMCSA is free. FMCSA controls when the update shows in its records.

Revocation in detail

Revocation applies to operating authority under 49 CFR Part 365, which depends on insurance on file under Part 387 and a BOC-3 under Part 366. FMCSA revokes operating authority for reasons other than the MCS-150 - for example, when required insurance on file lapses and is not replaced, or when no BOC-3 is on file. It is a separate process from USDOT deactivation.

Revoked MC authority requires a separate reinstatement: the carrier fixes the underlying cause (for example, getting required insurance filed again) and then goes through FMCSA's reinstatement process. Filing an MCS-150 alone does not reinstate revoked authority.

How to check your status

You can look up a carrier in FMCSA's Motus public search by USDOT number or company name. Check both the USDOT status and any operating authority status - they are separate records and can differ.
