FMCSA insurance file as of November 15, 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 #4731284: when, where, and which vehicles (type, make, VIN) the inspector recorded.

Why it may matter: Load scams often start with a phone or email that doesn't match the FMCSA record, so a recent change is worth knowing about.
What it doesn't show: Companies change numbers for ordinary reasons. The change doesn't show who made it.
Next step: Call the number now on file to confirm any load, not a number from an email or text.

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
