FMCSA insurance file as of May 14, 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 #4345382: 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.

MC number added
None → MC 1724949
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.
