What does the FMCSA actually require before it grants authority?
Before the FMCSA activates your authority, your insurance company has to file proof of liability coverage directly with the federal government on your behalf. For a motor carrier, that liability filing is generally made on a form called the BMC-91 (or BMC-91X), which certifies you carry public liability insurance at or above the federal minimum for the kind of freight you haul. The required minimum depends on what you carry: $750,000 for general (non-hazardous) freight in vehicles over 10,001 lbs, $1,000,000 for oil and certain hazardous materials, and $5,000,000 for bulk hazardous substances and certain explosives or poison gases (49 CFR 387.9). Your agent files the form; you do not file it yourself.
Two things worth knowing up front. First, the filing is what ties your insurance to your authority — let the policy lapse and the filing falls, and your authority can be put out of service. Second, cargo insurance: the FMCSA only requires a cargo filing for household-goods movers ($5,000 per vehicle / $10,000 per occurrence, via BMC-34). General freight carriers aren't federally required to file cargo insurance — but you'll carry it anyway, because brokers and shippers won't load you without it. (Source: FMCSA, 49 CFR 387.)
What coverage does a brand-new MC actually need to start hauling?
The federal filing is the floor, not the finish line. The coverage that gets you loaded is what your brokers and shippers require, and most won't book you without proof of it. A new authority's working checklist usually runs: primary liability (the filed coverage that protects others when you're at fault), motor truck cargo (protects the freight you're hauling), and physical damage (protects your own truck and trailer). From there, owner-operators often add non-trucking/bobtail for when you're driving without a load under dispatch, trailer interchange if you pull others' trailers, and occupational accident for the driver. This is the same full stack Flatland writes on the trucking pillar — we just front-load the pieces a new MC needs on day one. Brokers will ask for a certificate naming the required limits before your first load, so the goal is to have it in hand, not in process.
Coverage map
What coverage do you need to operate under your own authority?
One table — the working coverage map for a new MC:
| Coverage | Why you need it | Required by |
|---|---|---|
| Primary liability (filed) | Pays others when you're at fault; the FMCSA filing rides on it | FMCSA (BMC-91/91X); $750K general freight, more for hazmat |
| Motor truck cargo | Protects the freight you're hauling | Brokers & shippers (proof required) |
| Physical damage | Protects your own truck and trailer | Lender/lienholder; you, in practice |
| Non-trucking/bobtail | Covers driving without a load under dispatch | You (gap most new MCs miss) |
| Trailer interchange | Covers trailers you pull that aren't yours | Whoever's trailer you're hauling |
| Occupational accident | Injury coverage for the driver | You (workers'-comp alternative) |
(Federal minimums confirmed against 49 CFR 387.9 as of June 2026; re-check before relying on them — these rules change.)
How fast can a new authority get insured — and what does it cost?
New authority is a race against your own start date: the filing has to be on record before the FMCSA activates you, and your brokers want a certificate before your first load. That's the whole point of our new-authority angle — we get the liability filing submitted and the cargo/physical-damage certificate issued quickly, so the paperwork isn't what holds up your first dispatch. Cost depends on your equipment, your driving and CDL history, the freight you'll haul, and your radius — a brand-new MC with no operating history is priced differently than an established carrier, and we'll size it to your actual operation rather than a guess. The fastest way to a real premium is a quote — we don't publish figures that wouldn't match your operation.

FAQ
Getting-your-own-authority FAQs
- Do I have to file anything with the FMCSA myself?
- No — your insurance company files proof of your liability coverage with the FMCSA on your behalf (generally the BMC-91/BMC-91X filing). You buy the policy; the filing rides on it.
- What's the minimum insurance the FMCSA requires?
- For public liability, the federal minimum is $750,000 for general freight, $1,000,000 for oil and certain hazardous materials, and $5,000,000 for bulk hazmat and certain explosives (49 CFR 387.9). Most carriers carry more than the floor — we'll size it to your freight type.
- Is cargo insurance required to get my authority?
- The FMCSA only requires a cargo filing for household-goods movers. For general freight it isn't a federal mandate — but you need cargo coverage anyway, because brokers and shippers won't load you without proof of it.
- How fast can I be insured on new authority?
- Often quickly — getting the liability filing in and the certificate issued is what we move fast on, so paperwork isn't what delays your first load. Timing depends on your equipment and history.
