USS United Site Services operates as a private property carrier based in Meridian, Idaho, with 218 power units and 164 drivers. The carrier has been registered since 1994 and logged approximately 3.4 million miles in 2025. Vehicle out-of-service inspections occurred at a rate of 22.7%, slightly above the snapshot benchmark of 21.2%, while driver out-of-service inspections were at 7.1%, above the snapshot benchmark of 5.2%. HaulReport-estimated percentiles place the carrier at 9.7 for controlled substances, 11.6 for hours-of-service compliance, and 30.4 for vehicle maintenance—an independent estimate, not an official FMCSA or CSA score.

HaulReport interpretation — automatically generated from the public FMCSA data below and our percentile estimates, and checked against those source figures.

FMCSA sets each carrier's biennial update month from the last two digits of the USDOT number (last digit → month, second-to-last digit → odd/even year) — it is required even when nothing has changed. This is a schedule derived from the public rule, not a compliance determination. Verify and file on FMCSA · Deadline calculator

Independent estimate — not an official FMCSA or CSA score. Highest estimated percentile band: Low.

This percentile is an independent estimate produced by ranking FMCSA's publicly published BASIC measure within a safety-event peer group. FMCSA does not publish percentiles for property carriers; this figure is HaulReport's reconstruction and may differ from any internal FMCSA value. Bands describe percentile ranges among peers, not safety judgments. It is provided for general informational purposes only; it is not a consumer report and may not be used for any purpose governed by the Fair Credit Reporting Act (including credit, insurance, employment, or tenant screening), and it is not a safety rating, a fitness determination, legal advice, or a recommendation to do business with any carrier. Always verify against official FMCSA sources before relying on it.
