Do not book until these are resolved · 1 signal
How risk signals workAt least one fact in the FMCSA record should stop a booking until it is cleared up. Confirm the current record on Motus first; it is not a finding of wrongdoing. Authority and insurance are last known from May 14, 2026.
- Operating authority is not authorized (last known)Without active authority the company may not haul or broker interstate freight for hire.
No cargo cover filed with FMCSA
Green means the FMCSA record shows it. It does not confirm who you are talking to, or that a policy covers your specific load.
Not a live check. FMCSA has not published a Motus record for this carrier, so authority and insurance show the last known status from May 14, 2026. Confirm on Motus ↗ before booking.
What to verify next
- Confirm authority and insurance on the official Motus record ↗: our copy is the last known status from May 14, 2026. Safety record: SAFER ↗.
- Call back on the number on file, (530) 713-7304, not a number from an email or load board.
- Check that the MC number you were given is MC1589964.
- Ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.

How these rates are calculated
Period: Oct 18, 2024 – Oct 18, 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 398,428 vehicle and 509,934 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
5 violations counted in FMCSA's Safety Measurement System (SMS), 0 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 9 violations above?
The inspections section's number counts every violation written on the inspection reports in our Oct 18, 2024 – Oct 18, 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 JTB TANK LINES LLC
What does JTB TANK LINES LLC's operating authority allow?
FMCSA records show no active operating authority for JTB TANK LINES LLC (MC1589964), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about JTB TANK LINES 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. 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 JTB TANK LINES LLC?
Confirm the authority and insurance on the Motus record for USDOT 4144879. Call the company back on the phone number on file, (530) 713-7304, not a number from an email or load board message.
