Every roadside inspection in FMCSA's file for USDOT #4937402: 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.
Noticed by THC November 1, 2026 (changed after our October 31, 2026 copy)
First seen in FMCSA's census file
FMCSA lists this USDOT as added October 28, 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
The USDOT number is active, but FMCSA's records show no active for-hire carrier operating authority as of November 15, 2026. Without it the company can't haul brokered freight across state lines for hire.
