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 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 343,539 vehicle and 454,274 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

61 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 87 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 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.
