If you’ve been on trucking forums or YouTube lately, you’ve probably seen two opposite claims: “MC numbers are eliminated!” and “Nothing changed, ignore the hype.” Both are wrong — and if you’re starting a new authority, the details matter, because your insurance filings are tied directly to your registration.
Here’s what actually changed, straight from FMCSA’s own registration modernization documentation, and what it means for your insurance.
What Motus is
FMCSA replaced its aging registration systems with Motus: USDOT Registration System — a single online platform where carriers, brokers, and freight forwarders apply for and manage their operating authority. The goals are fraud prevention, identity verification, and a faster, mobile-friendly process.
For a new trucking company, the practical experience is different from what drivers who registered years ago went through: one company account, document uploads, real-time validation, and agency letters (like your authority certificate) emailed to you instead of arriving only by mail.
So… do MC numbers still exist?
Mostly, yes — with changes:
- Existing numbers don’t change. If you already have a USDOT and MC number, you keep both, exactly as they are.
- MC/MX/FF prefixes are still being issued. FMCSA has said directly that Motus “will continue to issue docket numbers and prefixes (MC/MX/FF) will remain the same.”
- New numbers are randomized. To fight fraud, newly issued USDOT numbers and docket numbers no longer follow a predictable sequence.
- One docket number per new authority. Under the old system, multiple authorities could share one docket number. In Motus, each newly granted authority gets its own unique docket number with its own history.
- USDOT suffixes are new. Companies registering for the first time see suffixes next to their USDOT number identifying the type of entity and registrations granted. (These are not a truck-marking requirement.)
- Full elimination of docket numbers is only “under consideration.” It would require a formal rulemaking with public comment. It has not happened.
Bottom line: the industry is moving toward the USDOT number as the single identifier, but the “MC numbers are gone” headlines got ahead of reality.
The part that doesn’t change: insurance is the gate
Whatever the registration system looks like, one rule stays constant: FMCSA will not activate your authority until your insurance company files proof of coverage. No filing, no authority.
The federal minimum liability limits (49 CFR Part 387) depend on what you haul:
- General freight, vehicles over 10,001 lbs GVWR: $750,000 — though in practice most brokers and shippers require $1,000,000, so that’s what nearly every new authority buys.
- Oil and certain hazardous materials: $1,000,000.
- Other hazmat classes: $5,000,000.
Your insurance carrier submits the federal filing (the BMC-91 or BMC-91X form) electronically. You don’t file it yourself — but you do need an agent who files it promptly, because of the deadline below.
The 90-day trap
New applicants must have proof of insurance on file within 90 days of applying. Miss the window and the application is dismissed — you start over and pay the registration fee again.
This deadline catches a surprising number of new owner-operators who get their paperwork started, then spend two months truck shopping. The fix is simple: get your insurance quote moving before or at the same time as your authority application, so binding and filing takes days, not weeks.
What a new authority actually buys
A complete first-year program usually includes:
- Auto liability ($750k minimum, usually $1M) — the federally filed coverage.
- Motor truck cargo (typically $100,000) — not federally required for general freight, but brokers won’t load you without it.
- Physical damage — protects your truck and trailer; required if financed.
- Non-trucking liability / bobtail — if you also run leased-on or drive the truck off dispatch.
- General liability — often required by shippers and for some contracts.
New-authority premiums are the highest you’ll ever pay — carriers price the first 12–24 months of a new DOT number cautiously. The good news: with clean inspections and no claims, renewals typically improve significantly.
What to do if you’re starting an authority in 2026
- Apply through FMCSA’s Motus system (portal.fmcsa.dot.gov) — expect identity verification.
- Start your insurance quotes the same week. Have ready: truck/trailer details, radius, cargo type, and driver history.
- Bind coverage and have your agent file the BMC-91/91X immediately — well inside the 90-day window.
- File your BOC-3 (process agent designation).
- Expect the new-entrant safety audit within your first months of operation.
Where a specialist broker earns their keep
New-authority insurance is a specialty market: many standard carriers won’t touch a fresh DOT number at all, and the ones that will price it very differently from each other. As independent brokers, we quote your authority across multiple trucking carriers at once, handle the federal filings, and get COIs out the same day — in English or Russian.
