Wyoming DVIR and vehicle inspection rules

Last reviewed November 12, 2026.

This page summarizes what we could verify from official sources about how Wyoming applies driver vehicle inspection and related vehicle-inspection rules. It is not a complete reprint of Wyoming law.

Interstate operations

If you operate a commercial motor vehicle in interstate commerce to, from, or through Wyoming, the federal Motor Carrier Safety Regulations (FMCSRs) apply, including 49 CFR Part 396 and the DVIR rules in § 396.11 and § 396.13. State rules do not replace those federal interstate requirements. Start with What a DVIR is and who must complete one.

State agency

For Wyoming-specific questions, including how the rules apply to operations that stay entirely inside Wyoming, contact Wyoming Highway Patrol.

What official sources say about state adoption

As of the date this page was reviewed, we did not independently verify a current official Wyoming statute or administrative-rule section adopting 49 CFR Part 396 from an official text we could quote here.

Intrastate operations and variations

Confirm current Wyoming adoption of Part 396, including any intrastate weight threshold or DVIR exception, with the Wyoming Highway Patrol and by reading the current official Wyoming motor-carrier safety rules.
