How these rates are calculated

Period: Oct 20, 2024 – Oct 20, 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 398,391 vehicle and 509,953 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

Violations in FMCSA's SMS last 24 months

10 violations counted in FMCSA's Safety Measurement System (SMS), 2 of them serious enough to put the driver or vehicle out of service.

Why is this different from the 12 violations above?

The inspections section's number counts every violation written on the inspection reports in our Oct 20, 2024 – Oct 20, 2026 window. The SMS count comes from FMCSA's own monthly SMS snapshot, which uses its own 24-month window and only the violations it scores. Both are FMCSA figures; they measure different things.

Questions about Gilmore Liquid Air Co

What does Gilmore Liquid Air Co's operating authority allow?

FMCSA records show no active operating authority for Gilmore Liquid Air Co (MC421377), so it may not haul regulated interstate freight for hire or broker loads under these dockets.

Which information about Gilmore Liquid Air Co 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.

What should I verify before booking Gilmore Liquid Air Co?

Confirm the authority and insurance on the Motus record for USDOT 1004102. Call the company back on the phone number on file, (626) 443-1361, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC421377, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
