Facts 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. How this works
- Operating authority is inactive (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, (209) 599-4543, not a number from an email or load board.
- Check that the MC number you were given is MC565733.
- 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
6 violations counted in FMCSA's Safety Measurement System (SMS), 1 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 19 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.

"Share" is this company's mix of violations; the California column is the mix across all California-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.

Questions about SAPPHIRE MATERIALS INC
What does SAPPHIRE MATERIALS INC's operating authority allow?
