Getting your own authority is exciting and confusing in equal measure. Between the FMCSA, filings with names like BMC-91 and BOC-3, and insurers who all say something slightly different, it's easy to lose track of what you actually need. Here's the plain-English version.
The numbers: USDOT and MC
Most interstate for-hire carriers need both a USDOT number (your safety identifier) and an MC number (your operating authority). You apply through the FMCSA's Unified Registration System. Your authority isn't active until the required insurance and process-agent filings are on record.
The BMC-91 (or 91X): proof of liability
This is the filing that proves you carry the federally required public liability insurance. Your insurance company files it electronically with the FMCSA on your behalf, you don't file it yourself. For most general freight carriers the federal minimum is $750,000 in liability, but $1,000,000 is the practical standard most brokers and shippers require.
Higher minimums apply to certain commodities, hazmat in particular can require $5,000,000. The right limit depends on what you haul.
The BOC-3: your process agents
The BOC-3 designates a process agent in each state where you operate, someone who can receive legal documents on your behalf. It's filed by a process-agent service, not your insurer, and it's a one-time requirement to activate authority.
What insurers look at for a new authority
- Your driving history and years of verifiable experience.
- The equipment you'll run and its value.
- What you plan to haul and your operating radius.
- Whether you're truly new, or an experienced driver starting your own authority (which prices better).
The reality of new-authority pricing
New authorities pay more, there's no way around it. Insurers have no loss history to price against, so the first 12 months are the most expensive. The good news: a clean first year, and time in business, brings rates down meaningfully at renewal.
A broker who works with new authorities regularly knows which carriers actually want new-venture business instead of declining it. That's the difference between getting placed and getting stuck.
