If your MCS-150 biennial update is coming due and you have been getting nowhere on FMCSA's website, you are not doing anything wrong. FMCSA has temporarily paused the biennial update requirement while its brand-new registration system, Motus, works through a very bumpy launch. Here is the plain-English version of what happened and what it means for your authority.
The headline: the biennial update is temporarily suspended
On its registration site, FMCSA has temporarily suspended enforcement of the biennial update, and just as importantly, it has stopped inactivating USDOT numbers for carriers who have not completed a required update.
The key line for owner-operators and fleets: if your biennial update was due on or after June 1, 2026, you get additional time, and your USDOT number will not be inactivated for failing to submit it during this window. FMCSA says it will share more guidance as "Motus recovery and stabilization efforts continue."
Translation: nobody is losing their authority right now over a missed biennial update caused by the system being broken. That is a real relief, but it is temporary, so it is worth understanding what is going on behind it.
What Motus actually is
Motus is FMCSA's new USDOT Registration System, and it went live for carriers on May 19, 2026. It is meant to replace the decades-old patchwork of separate FMCSA registration systems with a single online account where a carrier manages everything in one place: your USDOT number, your MCS-150 updates, operating authority, hazmat registration, the single-state registration system, and your financial responsibility filings (your BOC-3 and insurance).
The old setup forced you to bounce between multiple disconnected portals, fill out redundant forms, and wait weeks for anything to process. Motus was pitched as a modern, mobile-friendly, one-stop replacement with real-time data validation and auto-population, so an update that used to take a week of back-and-forth would take minutes.
When it rolled out, and in what order
- December 2025 (Phase 1): Limited access opened for supporting companies only, meaning BOC-3 process agents, insurance companies, and transportation service providers. They could set up accounts, but not file yet.
- May 19, 2026 (Phase 2): The system opened to everyone else, including motor carriers, brokers, and freight forwarders, with full registration and update functionality. This is the launch most carriers actually felt.
- Ongoing (Phase 3): Continuous fixes and added features based on how the first two phases go.
Why FMCSA built it
Two reasons, and both are legitimate on paper.
First, fraud. The legacy registration system had become a playground for chameleon carriers, shell companies, and bad actors reusing identities. Leadership at the Department of Transportation publicly called the old system lax and decrepit and tied it to foreign shell companies gaming registration. Motus adds identity verification through Login.gov and IDEMIA and runs business-verification and edit checks meant to catch suspicious or inconsistent filings before they go through.
Second, modernization. The systems Motus replaces were old, disconnected, and slow. Consolidating them into one account with real-time validation is genuinely overdue.
The goals are good. The execution is where it fell apart.
How bad the rollout has been
Bluntly: rough. The problems started on day one and are still being worked through months later.
- Carriers could not claim their own USDOT numbers. On launch day, May 19, many carriers simply could not link to their USDOT number, which blocked MCS-150 updates, address changes, reinstatements, and reactivations. FMCSA reported the core claim problem fixed the next morning, but that was only the first of many.
- The volume buried it. In its first week the system took on roughly 120,000 new user applications and 13,000 carrier USDOT claims, all while migrating decades of old data, on a platform that clearly had not been stress-tested for that load.
- Verification and login failures. Carriers hit login lockouts, failed DOT-number linking, and identity-verification errors that stopped them cold before they could do anything.
- Wrong data showing on records. Operating authority and insurance status displayed incorrectly for many carriers, which is not a cosmetic problem when brokers and shippers pull your record before giving you a load.
- Slow help. Carriers reported long phone holds and fixes that took days to weeks per case.
FMCSA has been in visible cleanup mode: it paused USDOT deactivations tied to these issues, prioritized insurance and authority fixes, and extended its contact center hours to 8:00 AM to 11:00 PM EST on weekdays plus Saturdays. The biennial update suspension at the top of this article is part of that same damage control.

What you should actually do right now
The suspension buys you breathing room. It is not a reason to ignore your registration.
- Do not panic about a missed biennial update if yours came due on or after June 1, 2026. Your USDOT number is protected during this window. See our full guide on filing your MCS-150 so you are ready to file the moment the system cooperates.
- Check your own record. Use the public Motus search to pull your USDOT number and confirm your operating authority and insurance status are showing correctly. If your record is wrong, that can cost you loads even though it is FMCSA's error, not yours.
- If something is broken, open one ticket and leave it. FMCSA's guidance is explicit: do not open duplicate tickets on the same case, just follow up. The contact center is 1-800-832-5660.
- Sign up for FMCSA registration alerts so you hear about fixes as they land, instead of guessing.
- Keep your own paper trail. Screenshot your filings, confirmations, and any error messages. If your authority or insurance status is displayed wrong, your own records are what get it corrected.
- Do not pay a scam letter. The registration industry's favorite moment is confusion, and there is plenty of it right now. FMCSA does not charge for the biennial update, and no third party is required to "process" your Motus account.
How McClure helps
Your insurance filings live inside this same system, so when Motus shows your authority or your financial responsibility wrong, it is our problem too, and we watch for it. If you are a McClure client and your USDOT record looks off, your biennial window is coming up, or you just cannot tell whether you are compliant right now, call us. We will pull your record with you, confirm your filings match your policy, and help you sort out what is a real issue versus what is just Motus still catching up. You should not have to lose sleep, or loads, over a government system that is still finding its feet.
