Wyoming Commercial Truck Insurance: Requirements & Costs

Do You Need Commercial Truck Insurance in Wyoming?

If you haul freight for hire in Wyoming, you need commercial truck insurance. Cheyenne anchors the I-25/I-80 crossroads, Casper is the state's oil and gas hub, and Gillette sits atop the Powder River Basin — the largest coal-producing region in the country. Your required limits depend on your truck's weight, your cargo, and whether you run interstate or intrastate.

Wyoming Commercial Truck Insurance Requirements

Federal (FMCSA) requirements for interstate carriers

• $750,000 — non-hazardous freight in vehicles over 10,001 lbs
• $1,000,000 — transporting oil
• Up to $5,000,000 — certain hazardous materials

Interstate carriers file an MCS-90, plus a Form E or SR-22 where required. Coal, oilfield, and tanker haulers carry higher limits and pollution coverage.

Wyoming (intrastate) requirements

Intrastate carriers must meet Wyoming's financial-responsibility minimums, which vary by vehicle weight and cargo. Check your USDOT or docket number with the FMCSA to confirm what your operation needs.
