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 Tennessee average covers 76,674 vehicle and 133,842 driver inspections of all Tennessee-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 CERTIFIED CYLINDER LLC
What does CERTIFIED CYLINDER LLC's operating authority allow?
FMCSA records show no active operating authority for CERTIFIED CYLINDER LLC (MC309200), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about CERTIFIED CYLINDER 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.
What should I verify before booking CERTIFIED CYLINDER LLC?
Confirm the authority and insurance on the Motus record for USDOT 104750. Call the company back on the phone number on file, (931) 484-1521, not a number from an email or load board message.
