What if my USDOT was deactivated for missing MCS-150?
Last reviewed October 24, 2026
File the overdue MCS-150 with current information. FMCSA controls when the update shows in its records. A carrier with a deactivated USDOT number can't operate until the update is filed.
A missed biennial update can lead to civil penalties and deactivation of the USDOT number (49 CFR 390.19T(b)(4)). Note: FMCSA has temporarily suspended enforcement of biennial updates and USDOT inactivation for updates due on or after June 1, 2026, until further notice. Deactivation applies to the USDOT number; the carrier record still exists, but its status shows as inactive in FMCSA's records. You can check the status in FMCSA's Motus public search by USDOT number or company name.
Recovery is the same as a regular biennial filing: file MCS-150 with current information (vehicles, mileage, address, all material changes since last filing). FMCSA controls when the update shows in its records.
MCS-150 updates are made online in Motus (motus.dot.gov) with a Login.gov sign-in linked to your USDOT number. If you would rather not do it yourself, a filing service can help: the MCS-150 is prepared and submitted for you.
