FMCSA insurance file as of November 14, 2026.
Filings are the active or pending insurance policies FMCSA lists for this company; our copy refreshes nightly. Coverage amounts are not shown per policy.
From FMCSA's authority history (its current Motus system, plus the older L&I history it froze on May 14, 2026). "First granted" is the earliest grant on record; "on record since" is the earliest action FMCSA has when the grant itself is older than its electronic records. "Active since" is the latest grant or reinstatement, so a lapse that FMCSA reinstated restarts the clock.
From FMCSA's Safety Measurement System files, October 2024 to October 2026. Crash counts include crashes the carrier didn't cause. Out-of-service rates use only inspections that checked the driver or the vehicle.
Every roadside inspection in FMCSA's file for USDOT #4631999: when, where, and which vehicles (type, make, VIN) the inspector recorded.
THC compares FMCSA's files every night and keeps what changed. Tracked since October 30, 2026, last compared November 14, 2026.
Noticed by THC November 14, 2026 (changed after our November 13, 2026 copy)
MC number added
None → MC 98386427
Why it may matter: The MC (docket) number is what brokers and shippers use to check operating authority.
What it doesn't show: Having an MC number does not mean its authority is active.
Next step: Check the authority status for the new MC number.

Authority granted
FMCSA dates the grant November 11, 2026
Why it may matter: Newly granted authority means the company is just starting that kind of work.
What it doesn't show: A grant date says nothing about how the company operates.
Next step: Check that insurance (or a broker's bond) is on file.

Liability insurance on file changed
None on file → $750,000
Why it may matter: For-hire carriers must keep liability (BIPD) insurance on file with FMCSA to keep authority active.
What it doesn't show: The amount on file is the filing, not the full policy. It doesn't show deductibles or exclusions.
Next step: Ask for a current certificate of insurance and confirm it with the insurance company directly.

Motor carrier operating authority changed
Pending → Active
Why it may matter: Authority status decides what interstate for-hire work a company may legally do.
What it doesn't show: FMCSA's daily file shows the status, not the reason (for example missing insurance, a request by the company, or an order).
Next step: Run a live check, and confirm with the company using the phone number on its FMCSA record.

First seen in FMCSA's census file
FMCSA lists this USDOT as added October 6, 2026
Why it may matter: A newly listed USDOT number is often a new company. New companies have little inspection or payment history yet.
What it doesn't show: This is the night THC first saw the record. It is not the registration date unless FMCSA's add date says so.
Next step: Check whether operating authority is active and insurance is on file before working together.
Source: FMCSA Company Census File (data.transportation.gov).
Dates are when THC noticed the change in FMCSA's files, not when it happened, unless FMCSA's file gives the date. FMCSA's files can lag behind FMCSA's own systems. Check this record on FMCSA SAFER · Daily FMCSA change reports
