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 #3143810: 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.
No changes seen in the details THC tracks (status, name, phone, MC number, authority, insurance and bond filings) since October 30, 2026. That covers only what FMCSA's public files show.
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

From public FMCSA records (the Company Census File, FMCSA's daily authority and insurance file and its monthly Safety Measurement System inspection and crash files).
