Nothing in the FMCSA record matched our risk signals. That is not a guarantee; follow the checks below. Authority and insurance are last known from May 14, 2026.
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, (806) 930-0489, not a number from an email or load board.
- Check that the MC number you were given is MC1170363.
- 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 Texas average covers 347,521 vehicle and 460,200 driver inspections of all Texas-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 DIEGO YACIEL SANTIESTEBAN CASTELL
What does DIEGO YACIEL SANTIESTEBAN CASTELL's operating authority allow?
MC1170363: Common carrier (may haul regulated property for hire for the general public).
Which information about DIEGO YACIEL SANTIESTEBAN CASTELL 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. There are too few vehicle inspections in the last 24 months to judge the out-of-service rate. 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 DIEGO YACIEL SANTIESTEBAN CASTELL?
Confirm the authority and insurance on the Motus record for USDOT 2955318. Call the company back on the phone number on file, (806) 930-0489, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1170363, and ask the insurer for a certificate of insurance naming you as certificate holder.
