No risk signals found
How risk signals workNothing in the FMCSA record matched our risk signals. That is not a guarantee, and it does not confirm who you are talking to; follow the checks below.
MC825355: Broker active
Cargo cover filed: $5,000
Green means the FMCSA record shows it. It does not confirm who you are talking to, or that a policy covers your specific load.
What to verify next
- Confirm authority and insurance on the official Motus record ↗. Safety record: SAFER ↗.
- Call back on the number on file, (210) 661-6791, not a number from an email or load board.
- Check that the MC number you were given is MC80252 or MC825355.
- Ask for a certificate of insurance naming you as holder, with cargo coverage that fits your load; if it brokers your load, ask for proof of its BMC-84/85 bond or trust instead.
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. Cargo cover filed: $5,000.

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 Texas average covers 347,522 vehicle and 460,240 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 ↗
Violations in FMCSA's SMS last 24 months
100 violations counted in FMCSA's Safety Measurement System (SMS), 17 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 140 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 Texas column is the mix across all Texas-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.
