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 BN average covers 11,269 vehicle and 14,883 driver inspections of all BN-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
15 violations counted in FMCSA's Safety Measurement System (SMS), 3 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 24 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.

Questions about MARIO ALBERTO VARGAS DEMARA
What does MARIO ALBERTO VARGAS DEMARA's operating authority allow?
MX1523549: Common carrier (may haul regulated property for hire for the general public).
Which information about MARIO ALBERTO VARGAS DEMARA 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. 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. The MCS-150 was last updated Aug 7, 2024, so fleet size and contact details may be out of date.
What should I verify before booking MARIO ALBERTO VARGAS DEMARA?
Confirm the authority and insurance on the Motus record for USDOT 4014747. Call the company back on the phone number on file, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MX1523549, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
