How these rates are calculated
Period: Oct 19, 2024 – Oct 19, 2026. Vehicle rate = vehicle inspections with a vehicle out-of-service order ÷ vehicle inspections (levels 1, 2, 5 and 6). Driver rate uses levels 1, 2, 3 and 6. The California average covers 398,742 vehicle and 510,354 driver inspections of all California-based carriers in this period. It mixes every type of operation, so compare with care; rates based on a handful of inspections say little. FMCSA's own SMS measures are weighted differently: SMS profile ↗ · SAFER snapshot ↗

Questions about CHANG WON PAK
What does CHANG WON PAK's operating authority allow?
FMCSA records show no active operating authority for CHANG WON PAK (FF58575), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about CHANG WON PAK is old or missing?
Operating authority is the last known status from the FMCSA snapshot of May 14, 2026, not a current check. No insurance filings were found in the public data. FMCSA has not issued a safety rating, which means no compliance review is on record, not that the carrier is unsafe. The MCS-150 was last updated Jul 4, 2024, so fleet size and contact details may be out of date.
What should I verify before booking CHANG WON PAK?
Confirm the authority and insurance on the Motus record for USDOT 4020327. Call the company back on the phone number on file, (415) 518-9172, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches FF58575, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
