MCS-150 for restarting a deactivated USDOT
Your USDOT was deactivated — voluntarily, for missed MCS-150, or for an extended period of inactivity. You want to resume operations. We file the MCS-150 to reactivate the USDOT for $100 same-day. Most reactivations land within 24-48 hours of FMCSA processing under 49 CFR §390.19.
How USDOT deactivation works
FMCSA flags a USDOT as inactive in three main scenarios: voluntary deactivation (the carrier requested it), missed MCS-150 biennial update for an extended window (typically 60+ days past due), or extended inactivity with no operational signals. The deactivation is reflected in SAFER as “NOT AUTHORIZED” and the carrier shows as inactive to brokers, shippers, and roadside inspectors.
Reactivation is straightforward in most cases — file a fresh MCS-150 with current carrier info, ensure insurance and BOC-3 are current, and the USDOT typically flips back to ACTIVE within 24-48 hours of FMCSA processing. See the how-to-file walkthrough and the late-filing FAQ for the FMCSA-side detail.
What also needs to be current
- BOC-3 process agent — verify or refile ($75 at FastBOC3)
- BMC-91 insurance — must be active before operations resume
- UCR registration — annual filing for the current year
- State IRP / IFTA — coordinate with state DMV for plate reactivation
- Form 2290 HVUT — current-year stamped Schedule 1 for IRP
What's included
- Form MCS-150 prepared and filed with FMCSA same-business-day
- SAFER monitoring through reactivation
- Reactivation confirmation
Reactivation questions
How long does my USDOT stay valid for reactivation?
Indefinitely under most scenarios. FMCSA does not retire deactivated USDOTs the way some state agencies retire dormant entities. A USDOT deactivated for two years for missed MCS-150 typically reactivates with a fresh MCS-150 filing — same USDOT number, same MC if applicable, same SAFER history. The exception is voluntary surrender — once a carrier formally surrenders the USDOT, restarting requires a new application.
Will SAFER show my old safety scores when I reactivate?
Generally yes, with the BASIC scores carrying forward from the carrier's prior period of activity. The 24-month BASIC measurement window resets gradually as the carrier accumulates new inspection events; old data ages out per the 24-month rolling window. A carrier that was deactivated for two years sees a relatively clean BASIC slate at reactivation because most of the prior data has aged out.
Do I need to refile BOC-3 and insurance to restart?
Both typically need to be current. BOC-3 may still be on file from before deactivation but should be verified through FMCSA L&I — process agents sometimes drop their BOC-91 registrations during the gap. Insurance has to be active before any operations resume; the BMC-91 needs to reflect a current policy. Most restarting carriers refile both BOC-3 (cheap, $75 one-time) and BMC-91 (insurer-side filing) as part of the reactivation.
