FMCSA quietly turned off its legacy registration portal on May 14, 2026 and replaced it with a completely new system called Motus. If you have not logged in to update your MCS-150 since then, the first time you do, you will be redirected to Login.gov, asked to complete multi-factor authentication, and required to have your Company Official's email match exactly what was on file in the old portal. Many carriers are finding out the hard way -- when a biennial update deadline hits and the account cannot be claimed. This is the practical 2026 walkthrough of what Motus is, what it does not change, and the 5-step prep every bus carrier should complete before their next filing.

FMCSA Motus Registration Guide for Bus Companies
The system that replaced the legacy FMCSA Portal, the 5 prep steps every carrier needs, and the MCS-150 biennial deadlines that still trigger a $10,000 penalty when missed.
Phase I Launch
Motus opened to supporting companies for testing and validation.
Federal Register Notice
FMCSA officially announced Motus availability via FR-2026-08334.
Legacy Portal Retired
Legacy FMCSA Portal registration systems yielded to Motus. Old system decommissioned.
Open to All Users
Motus opened to all new and existing registrants. Company Officials began claiming records.
Live for All Carriers
Every bus company must use Motus for USDOT registration, MCS-150 updates, and operating authority actions.
What Motus Replaces (And What Stays Exactly the Same)
Three legacy systems collapse into one. The regulations behind them do not change at all.
Unified Registration System
URS · retired 2026MCMIS Registration Functions
Motor Carrier Management Info SystemLicensing & Insurance
L&I · est. 1994MOTUS
USDOT Registration System- Login.gov identity + MFA
- Real-time data validation
- Auto-population, smart logic
- Consolidated dashboard
- Stronger business verification
What has NOT changed
Same number identifies the same carrier. No re-issuance.
Continues to exist and remains valid.
Still due every 2 years. Same schedule based on USDOT number.
49 CFR requirements unchanged. Motus is the front door, not new law.
Existing registrations remain valid. Do NOT apply for a new USDOT just because Motus launched. See BusCMMS track existing USDOT + MC numbers per carrier → book a demo.
The 5-Step Prep Every Bus Carrier Should Complete
Straight from FMCSA official guidance. Miss step 2 and the account will not link.
- 1
Verify FMCSA Portal account is active
Foundation checkLog in to the legacy portal one last time to confirm the account exists and is accessible. If the account is locked, deactivated, or the password reset link fails, resolve that before attempting Motus. Deactivated portal accounts create Motus verification failures.
- 2
Confirm Company Official is an internal employee
CRITICAL · MOST-MISSEDThe Company Official on file must be an employee of the carrier, not a third-party service provider or outside consultant. If the current Portal listing shows a filing service, change it to an internal employee before Motus migration. Only the Company Official's Login.gov email can claim the USDOT record in Motus for the first time.
- 3
Match Login.gov email across systems
Identity gateThe Login.gov email used for the FMCSA Portal must match the Login.gov email used to log into Motus. Different emails means the USDOT record cannot be claimed on first login. Set up Login.gov with the same email as the Portal now, not at deadline pressure.
- 4
Submit an MCS-150 update to clean data
Data hygieneBefore migration, submit a Biennial Update (MCS-150) via the Portal "Registration" tab so the current data on file for your business is accurate. Motus's real-time validation catches inconsistencies -- fix them at the source now.
- 5
Claim your USDOT record in Motus
First loginOnce Motus is available, the Company Official logs in with Login.gov and multi-factor authentication, then claims the existing USDOT record. The record is validated against Portal data via matching email. From that point forward, all FMCSA registration actions happen inside Motus.
The 5-step prep is one-time work. The MCS-150 calendar it protects lasts the life of your USDOT number. See BusCMMS track Motus prep status per carrier → book a demo.
MCS-150 Biennial Update Rules Under Motus
Same rule as before. New system. Missing it still costs up to $10,000.
The MCS-150 biennial update is the federal registration refresh every motor carrier -- including every interstate bus operator -- must file every two years. Motus does not change the underlying requirement. It changes only where and how you submit it. The filing month is determined by the last digit of your USDOT number, and the odd or even year is determined by the second-to-last digit. Miss it and the penalties are real.
The 2-year cycle
Every 2 years, on your assigned filing month, even if nothing changed. A clean carrier with no updates still owes the biennial confirmation.
Your filing month by USDOT digit
Last digit of USDOT = month. Second-to-last digit odd = odd year, even = even year.
Missing your assigned filing month is the #1 reason USDOT numbers get deactivated. A deactivated number stops all interstate operation immediately. Reactivation requires a fresh MCS-150 and can take days.
You also must file within 30 days of any major change -- address, fleet size, operations, or out-of-business status. See BusCMMS auto-schedule MCS-150 by USDOT digit → book a demo.
The Login.gov + Company Official Trap
The identity piece that quietly locks bus fleets out of their own USDOT record.
The single biggest issue tripping up bus carriers on Motus first-login is the Company Official + Login.gov email match. Motus uses Login.gov (the federal government's single sign-on with multi-factor authentication) for identity verification. When you sign in for the first time, Motus checks whether the Login.gov email matches the Company Official email on file in the old FMCSA Portal. If it does, you claim the USDOT record and you are in. If it does not match, you cannot access your own registration -- and you have to work through FMCSA support to resolve it, which can take days or weeks. Miss a biennial deadline during that gap and you are into penalty territory.
Fixes that work
Verify Company Official today
Log in to the old Portal, check the Company Official listed. If it is a filing service or ex-employee, change it now.
Set up Login.gov with matching email
Create a Login.gov account using the same email address that appears as the Portal Company Official. MFA is required.
Assign a backup employee
Add a second internal Company Official as backup. If the primary leaves, your USDOT record is not held hostage.
Watch for the TSP registration scam
Some carrier email addresses are being registered as Transportation Service Provider (TSP) accounts in Motus without the carrier's knowledge. If you receive Motus notifications addressed to a TSP role you did not create, FMCSA provides a formal process to close the TSP account. Do not ignore it -- it can block legitimate access to your own USDOT record.
Login.gov mismatches and TSP scam traps are the two hidden risks driving most 2026 Motus support tickets. See BusCMMS log Company Official + Login.gov email per carrier → book a demo.

My USDOT number ends in 4, so my biennial was due in April. We had been using an outside filing service listed as our Company Official, and when Motus launched I couldn't claim our own record -- the Login.gov email didn't match anything internal. It took nearly three weeks working through FMCSA support to get Company Official transferred to me and the record claimed. We paid a $1,500 penalty during that gap. Moved every USDOT and MCS-150 date into BusCMMS the same week. Next biennial is scheduled with alerts 60 days out, and my name is on the record.

Frequently Asked Questions
What is FMCSA Motus and when did it launch?
Motus is the new FMCSA USDOT Registration System that replaces three legacy platforms: the Unified Registration System (URS), the registration functions of MCMIS (Motor Carrier Management Information System), and the legacy Licensing & Insurance system dating from 1994. FMCSA announced Motus in Federal Register Notice FR-2026-08334 on April 29, 2026. Phase I opened to supporting companies on December 8, 2025. The legacy FMCSA Portal registration systems yielded to Motus on May 14, 2026, and Motus opened to all new and existing registrants on May 19, 2026. Every motor carrier -- including every interstate bus company -- now uses Motus for USDOT number applications, MCS-150 biennial updates, operating authority changes, and other FMCSA registration actions. Motus does not change any underlying regulation; it is a new front door built for stronger identity verification and consolidated management.
Does Motus change my USDOT number or MCS-150 requirements?
No. Motus is a system change, not a regulatory change. Your USDOT number stays the same -- it continues to identify your carrier and requires no re-issuance. Your MC (operating authority) number, if you have one, also continues to exist and remains valid. The MCS-150 biennial update requirement is unchanged: every motor carrier must file an MCS-150 update every two years to keep the USDOT number active, even if no business information has changed. The filing month is still determined by the last digit of your USDOT number (1 = January, 2 = February, and so on, with 0 = October), and the second-to-last digit determines whether it is due in an odd or even year. What Motus changes is how you sign in (Login.gov with multi-factor authentication), how identity is verified, and where the record lives. The 49 CFR regulations behind all of this are unchanged.
What happens if I miss my MCS-150 biennial update?
Missing your MCS-150 filing deadline triggers a chain of consequences under 49 CFR. Civil penalties can reach up to $1,000 per day, capped at $10,000 per violation. Your USDOT number gets flagged for deactivation, and once deactivated, all interstate operating authority ceases -- you legally cannot operate an interstate bus route until reactivation is complete, which requires filing a fresh MCS-150 and can take days. Missing the assigned filing month is the #1 reason USDOT numbers get deactivated across the country. You also must file within 30 days of any significant change, including a business address update, fleet size shift, change in operations, company structure change, or notification that the business has ceased operating. Bus carriers with mixed interstate and intrastate operations often lose interstate authority first, then face secondary state-level consequences.
How do I prepare my bus company for Motus?
FMCSA's official guidance sets out five steps. First, verify your existing FMCSA Portal account is active and accessible -- resolve any locked or deactivated accounts before touching Motus. Second, confirm the Company Official on file is an internal employee, not a third-party filing service or outside consultant -- this is the most-missed step and the one that causes the most first-login failures. Third, ensure the Login.gov email used for Motus matches the Company Official email in the old FMCSA Portal -- mismatched emails prevent the USDOT record from being claimed. Fourth, submit a Biennial Update (MCS-150) through the Portal Registration tab to clean up any stale data before migration -- Motus's real-time validation catches inconsistencies. Fifth, once Motus is available, the Company Official logs in with Login.gov and multi-factor authentication, then claims the existing USDOT record. From that point forward, all registration actions happen inside Motus.
How does BusCMMS help bus companies stay compliant with Motus and MCS-150?
BusCMMS auto-schedules the MCS-150 biennial calendar per carrier based on the last digit of your USDOT number, with alerts 60 days before each carrier's assigned filing month. Company Official is tracked per carrier record with Login.gov email, verification status, and a backup employee tag so a single departure never locks you out of your own USDOT record. Every USDOT and MC number lives in a central reference during Motus first-login and audit prep. Fleet size changes, address moves, out-of-business status, and operations shifts trigger a 30-day MCS-150 filing reminder. Motus claim status tracks whether each carrier record has been claimed by the correct Company Official, so nothing gets forgotten during transition. Federal Motus registration and state DPU / RMV requirements sit in one carrier profile alongside driver certifications, DVIRs, and preventive maintenance -- no more spreadsheet plus email plus calendar. One 18-bus Southeast motorcoach operator reported eliminating their next biennial risk after moving USDOT and MCS-150 dates into BusCMMS with 60-day forward alerts.
