What Trucking Insurance Requirements Apply in Wyoming?

A contract carrier transporting people or property for compensation on Wyoming highways needs a WYDOT Letter of Authority and state-filed insurance or other approved security. WYDOT rejects ordinary ACORD certificates, binders, abstracts, and insurance cards for intrastate authority, so have the insurer submit the state’s prescribed form.

What Is Trucking Insurance?

Trucking coverage can address liability, damage to your trucks and cargo losses, but one quote may not include all three. If you haul goods for customers or yourself, compare those protections and check whether the quote needs motor-carrier or other commercial auto coverage. Read the national Trucking guide.

Wyoming Trucking Insurance Requirements

Requirement	Details
Intrastate contract-carrier insurance	File insurance or other approved security for cargo, public liability, and property damage; coverage must stay continuous while authority is active ^2,³
Acceptable proof	WYDOT-prescribed forms filed by an authorized insurer representative; standard ACORD certificates and binders are not accepted for intrastate authority ^1,³

What Should You Watch for With Trucking Insurance in Wyoming?

Use Wyoming’s Prescribed Filing Form
WYDOT lists Forms E, G, H, and other authority forms, and explicitly rejects ACORD certificates, binders, abstracts, and ID cards as intrastate proof. Ask the insurer which state form fits your liability and cargo filing; a certificate supplied to a customer will not replace it. ^1,³
A Filing Lapse Can Stop Wyoming Operations
Wyoming law requires continuous insurance or approved security; when cancellation takes effect, the carrier’s operating authority is suspended and no highway operation may resume until replacement security is approved. Coordinate effective dates and department approval before a renewal or insurer change. ²
Match the Filing to the Authority Applicant
Wyoming’s insurance rules call for the full legal name and any DBA exactly as used for the authority application. Have the broker check the filing name and every partner name, where applicable, before submission. ³
Cross-State Hauls Have a Federal Filing Too
Wyoming’s Letter of Authority addresses intrastate service; FMCSA separately requires interstate carriers with federal operating authority to keep the appropriate financial-responsibility forms on file. Ask the broker to verify both filings if your routes cross state lines. ^1,⁴

Which Trucking Insurance Providers Have Wyoming License Records?

No provider in our research has both a state license record and a listing for this coverage line. This does not establish that providers are unlicensed. Check the regulator’s license lookup and confirm availability with a provider when requesting a quote.

Who Regulates Insurance in Wyoming?

Wyoming Department of Insurance

The Wyoming Department of Insurance administers Wyoming insurance laws, oversees insurers and insurance producers within its authority, and provides regulatory and consumer resources.

Reported tax rate. 3% of premium ^8,⁹

The NAIC's state chart lists a 3% of premium charge for surplus-lines coverage for Wyoming (the chart's state entries were reviewed in October 2025). Your broker may collect the applicable amount with the premium. Surplus-lines insurers are not licensed in the state and generally are outside state guaranty-association protection; ask your broker to explain the insurer's financial protections and any diligent-search requirement that applies to your placement.

Trucking Insurance in Wyoming: Frequently Asked Questions

What insurance proof does Wyoming accept for intrastate trucking authority?

WYDOT requires its prescribed insurance forms and says it does not accept ACORD certificates, binders, abstracts, or insurance cards as proof for intrastate authority. Have an authorized insurer representative submit the proper form. ¹

Can a Wyoming intrastate carrier operate after its insurance filing is canceled?

No. Wyoming law says cancellation suspends the affected authority, and highway operations cannot resume until replacement insurance or security becomes effective and is approved by the department. ²

Does Wyoming intrastate authority replace FMCSA insurance filings?

No. WYDOT issues authority for intrastate transportation, while FMCSA requires financial-responsibility filings for carriers with federal interstate operating authority. Confirm that your filings match both kinds of service. ^1,⁴
