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
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, (303) 293-2931, not a number from an email or load board.
- Check that the MC number you were given is MC418195.
- 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 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 Colorado average covers 19,021 vehicle and 32,904 driver inspections of all Colorado-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
85 violations counted in FMCSA's Safety Measurement System (SMS), 24 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 120 violations above?
The inspections section's number counts every violation written on the inspection reports in our Oct 19, 2024 – Oct 19, 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.

"Share" is this company's mix of violations; the Colorado column is the mix across all Colorado-based carriers, so you can see which kinds of problems stand out. A high count partly reflects fleet size and how often trucks are inspected.
