How FMCSA authority and insurance records actually work, and what they do and do not tell you before you tender a load. Figures come from our own reading of the FMCSA files.
- Active authority does not mean insured
FMCSA takes a median of 17 days to suspend a carrier after its insurance is cancelled. For that whole window the public record still reads Active.
- Broker authority and the $75,000 bond — how to tell a broker from a carrier
Brokers hold MC numbers too. The one filing that distinguishes them sits at exactly $75,000, every time, and it is the cleanest signal in the public record.
- Cargo insurance vs liability — why the FMCSA record will not tell you if your freight is covered
Liability covers what the truck does to others. Cargo covers your freight. Every cargo filing in the data sits at $5,000, and that number is not a policy limit.
- Vetting carriers with a spreadsheet — what it catches and what it misses
Most small brokerages run a script into Excel rather than paying for a tool. It works, up to a point. Here is precisely where that point is.
- Looking for a Carrier411 alternative
An honest comparison of the carrier-monitoring options, including where each one is genuinely stronger than us and where the free approach is good enough.
- Certificate of insurance vs FMCSA filing — which one to trust
One is a federal record you can verify independently. The other is a PDF that arrived by email. They answer different questions and are forged at very different rates.
- FMCSA changed its data in May 2026 — your carrier script may have quietly stopped working
The legacy tables were frozen on 14 May 2026 and replaced by a new system. Anything built against the old ones is either broken or serving a snapshot that never changes.
- FMCSA insurance filings explained — BMC-91X, BMC-84, BMC-34 and the rest
What each form code on a carrier's record actually means, and which ones satisfy the federal requirement. Coverage amounts verified against 95,806 live filings.
- How long after an insurance cancellation does FMCSA suspend authority?
We measured it against 273 carriers that lost coverage and were later suspended. The median gap is 17 days — and for that whole window the public record still reads Active.
- How to check whether a carrier is legitimate before you tender
A checklist that survives contact with the actual FMCSA records, including the three places the public data will mislead you.
- How to read an FMCSA carrier record, field by field
What every section actually means, which fields answer the question you are asking, and which ones look authoritative but tell you almost nothing.
- How to spot a double-brokered load before it moves
The signals that show up in public records, the ones that only show up in the conversation, and why the FMCSA file alone cannot settle it.
- MC number vs USDOT number — what each one actually tells you
They are different registrations answering different questions, and only one of them is tied to operating authority. Confusing them is how uninsured carriers pass a check.
- New carrier red flags — what to check when there is no history
About 17,000 carriers hold authority less than a year old. Being new is not a red flag. Here is what actually is.
- Operating authority status explained — Active, Pending, Inactive, Withdrawn
One entity in four with an authority record is Pending, not Active. Here is what each status means and which reason codes matter.
- What happens when a carrier's insurance is cancelled
The sequence FMCSA actually follows, how long each step takes, and the specific window where the public record says one thing and reality says another.
- What insurance limits to require from a carrier, and why $750,000 is not enough
The federal minimum was set in 1980 and has never been raised. Here is what carriers actually carry, and where the gap between the floor and a real claim sits.
- What a BOC-3 filing is, and why it can suspend authority on its own
The process-agent filing nobody checks. It has no dollar amount and no coverage, and losing it takes a carrier's authority as surely as an insurance lapse.
- Why carrier insurance gets cancelled, and what each reason actually means
Most cancellations are not what they look like. Telling a real lapse from an insurer switch is the difference between a useful alert and noise nobody reads.
