Every roadside inspection in FMCSA's file for USDOT #1386399: 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
