How to File Your MCS-150 with the FMCSA

Filing MCS-150 is a 15-30 minute task if you have your fleet data handy and access to your FMCSA account. This guide walks through the Motus filing workflow (motus.dot.gov), the fields that trip people up, and the Login.gov sign-in step that now gates every online biennial update.

Before You Start: What You Need

Pull these together before you sign in to Motus so you do not lose the session:

• Your USDOT number — 6 to 8 digits.
• Login.gov credentials — Motus (motus.dot.gov) signs in with a Login.gov account.
• Legal business name and mailing address, matching exactly what the FMCSA has on file.
• Fleet inventory — straight trucks, truck tractors, and trailers, counted owned vs leased.
• Driver counts — split into within-100-miles and beyond-100-miles.
• Last calendar year mileage — total vehicle miles for the full prior year.
• Cargo classifications — what you typically haul (general freight, refrigerated, flatbed, tanker, etc.).
• Safety contact info — name, phone, and email of your designated safety employee or representative.

The Ways to File MCS-150

Method 1: File Yourself Through Motus (Free)

The FMCSA's Motus registration system at motus.dot.gov — which replaced the legacy URS portal in May 2026 — lets you submit MCS-150 online at no government fee. You sign in with your Login.gov account (see our Login.gov sign-in guide if access questions come up), walk through the form fields, and submit. FMCSA controls when the update shows in its records.

The friction is usually not the form itself — it is the sign-in step. If you have never set up Login.gov, create the account and link your USDOT number before your deadline month. If identity verification fails, use FMCSA's help resources or contact FMCSA. Starting early is the key.

Method 2: Use a Professional Filing Service

With a filing service, your MCS-150 is prepared and submitted to FMCSA for you. You provide your USDOT and fleet data; the fields are entered, the data is checked before submitting, and you get a PDF confirmation. FastMCS150 charges $175 standard for a single filing or $400 once for lifetime updates that cover every future biennial filing - plus $25 only if you need Login.gov setup help.

The value is not in the form entry itself — it is in catching the errors that cause rejections (wrong fleet counts, inconsistent mileage, name mismatches) before they hit the FMCSA. Common errors are covered in our MCS-150 mistakes guide.

Signing In With Login.gov

FMCSA no longer uses a USDOT PIN. Since Motus opened on May 19, 2026 (legacy systems were retired May 14), you sign in with Login.gov and link your USDOT number to your account. Where you stand depends on what you already have set up:

• If you already have a Login.gov account, sign in at motus.dot.gov — the MCS-150 filing takes minutes from that point.
• If you do not have Login.gov, create a free account at login.gov first. Identity verification is done online and usually completes in one sitting; once verified, your Login.gov credentials work across federal services.
• If identity verification fails or your USDOT number will not link, use FMCSA's help resources or contact FMCSA — start early.

FastMCS150 charges $25 only if you need Login.gov setup help, because the verification step cannot be fully automated.

Step-by-Step: Filing Through Motus

1. Sign in at motus.dot.gov with your Login.gov account.
2. Open your registration record and choose the option to update it — the MCS-150 / biennial update.
3. Review the pre-populated fields. Business name, USDOT, and address pull from your existing record — correct any data that is stale.
4. Enter fleet counts. Straight trucks, truck tractors, and trailers, with owned and leased counted separately. Do not double-count leased equipment.
5. Enter driver counts. Split into drivers operating within 100 air-miles of the work-reporting location vs drivers operating beyond 100 miles.
6. Enter last-calendar-year mileage. Use actual numbers (ELD, IFTA, odometer) — do not round to a marketing-friendly figure.
7. Confirm cargo classifications. Check every category that applies to freight you actually haul; unchecked categories are treated as “do not carry.”
8. Confirm hazmat status. Mark Yes or No — if Yes, additional hazmat-class questions appear.
9. Enter the designated safety representative. Name, phone, and email of the person who actively manages your regulatory compliance.
10. Review and submit. Motus gives you a confirmation number. Save it. FMCSA controls when the update shows in its records.

Confirming Your Filing

After submitting, look up the record in FMCSA's Motus public search by USDOT number or company name. FMCSA controls when the update shows in its records. Once it does, the “MCS-150 Date” field should show the current submission date, and the “Operating Status” should remain ACTIVE. If the date stays stale, log back into Motus to check whether the filing was rejected and look for a reason code. If the status shows INACTIVE instead, run the deactivation reinstatement process rather than retrying the submission.
