FMCSA insurance file as of November 15, 2026.
Insurer names and policy numbers appear here once our nightly copy has them. Run the live check for the current FMCSA filing.
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 #4459918: 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 15, 2026.

USDOT status changed
Active → Inactive
Why it may matter: An inactive USDOT number should not be used for interstate commercial trucking.
What it doesn't show: USDOT status is not operating authority. An active USDOT can still have no active MC authority.
Next step: Run a live check, and confirm with the company using the phone number on its FMCSA record.

Motor carrier operating authority changed
Pending → Inactive
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.

Why it may matter: Fleet size shows roughly how big the operation is.
What it doesn't show: These are the company's own MCS-150 numbers, not a count FMCSA checked.
Next step: Nothing needed unless other details changed too.

MCS-150 updated
FMCSA's file dates the update November 11, 2026
Why it may matter: Carriers must update the MCS-150 every two years. A fresh update means the fleet and contact details are recent.
What it doesn't show: The MCS-150 is filled in by the company itself; FMCSA doesn't check the numbers.
Next step: Nothing needed unless other details changed too.

MC number changed
MC 1758665 → MC 1793454
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.
