How risk signals workFacts from the FMCSA record that call for a closer look. They are not a finding of wrongdoing. Authority and insurance are last known from May 14, 2026.
- Operating authority is pending (last known)FMCSA has not granted the authority yet.
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, (575) 219-1639, not a number from an email or load board.
- Check that the MC number you were given is MC1627443.
- Ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
Insurance on file
Liability (BI&PD) pays for injury and damage to other people and property; it does not cover the freight. Cargo insurance covers the freight. FMCSA only requires cargo filings from household goods carriers and freight forwarders, so most carriers file none: ask for a cargo certificate that fits your load. No cargo cover filed with FMCSA.

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 New Mexico average covers 11,268 vehicle and 16,211 driver inspections of all New Mexico-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
57 violations counted in FMCSA's Safety Measurement System (SMS), 6 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 80 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 FOUR CORNERS TRANSPORT LLC
What does FOUR CORNERS TRANSPORT LLC's operating authority allow?
FMCSA records show no active operating authority for FOUR CORNERS TRANSPORT LLC (MC1627443), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about FOUR CORNERS TRANSPORT LLC is old or missing?
Operating authority is the last known status from the FMCSA snapshot of May 14, 2026, not a current check. Insurance filings are from the same May 14, 2026 snapshot. 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 FOUR CORNERS TRANSPORT LLC?
Confirm the authority and insurance on the Motus record for USDOT 4173159. Call the company back on the phone number on file, (575) 219-1639, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1627443, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
