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 Massachusetts average covers 21,932 vehicle and 35,941 driver inspections of all Massachusetts-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 KNOWLES ENTERPRISES LLC
What does KNOWLES ENTERPRISES LLC's operating authority allow?
FMCSA records show no active operating authority for KNOWLES ENTERPRISES LLC (MC1082826), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about KNOWLES ENTERPRISES LLC 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. There are too few vehicle inspections in the last 24 months to judge the out-of-service rate. 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 KNOWLES ENTERPRISES LLC?
Confirm the authority and insurance on the Motus record for USDOT 3375750. Call the company back on the phone number on file, (617) 710-5026, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1082826, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
