Frequently asked questions
About trucking companies in Wyoming
How many trucking companies are based in Wyoming?
FMCSA's census database lists 1,811 active motor carriers headquartered in Wyoming (WY) with at least 5 power units and a realistic driver-to-truck ratio. This page shows the top 100 ranked by fleet size; the full 1,811-carrier dataset is searchable on Carrier90.
What is the largest trucking company in Wyoming?
STATE OF WYOMING (headquartered in CHEYENNE) is the largest trucking company in Wyoming by fleet size, operating 1020 power units. View the full safety, insurance, and authority profile at https://c90.io/carrier/523617.
How are these trucking companies ranked?
Carriers are ranked by total power units (the count of self-propelled commercial vehicles in their fleet) as reported to FMCSA on Form MCS-150. Power units include tractors, straight trucks, and buses — but not trailers. We apply a quality filter that requires a driver-to-truck ratio between 0.3 and 5.0 to exclude obviously-erroneous self-reports (for example, 5,000 trucks with 0 drivers).
How is the Carrier90 trust score calculated?
The 0–100 trust score is computed from FMCSA data across five layers: (1) carrier type classification, (2) binary gates for hard rejections (revoked authority, no insurance, out-of-service), (3) confidence-weighted safety, crash, insurance, and authority signals, (4) chameleon-carrier cross-reference detection, and (5) decision floors that cap dangerously high ratings for carriers with red flags. Scores map to APPROVE (75–100), REVIEW (40–74), or REJECT (0–39).
Is this Wyoming carrier directory free to use?
Yes. All carrier lookups, trust scores, safety records, and chameleon-carrier risk flags on Carrier90 are free with no signup required. Paid tiers add carrier monitoring with email alerts, REST API access, and bulk exports.
