Arizona DVIR and vehicle inspection rules

Last reviewed November 12, 2026.

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

Interstate operations

If you operate a commercial motor vehicle in interstate commerce to, from, or through Arizona, 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 Arizona-specific questions, including how the rules apply to operations that stay entirely inside Arizona, contact Arizona Department of Transportation (ADOT).

What official sources say about state adoption

Arizona law authorizes the Department of Transportation to adopt motor-carrier safety rules. Official sources and later unofficial reprints commonly point to Arizona Administrative Code R17-5-202 (“Motor Carrier Safety: Incorporation of Federal Regulations; Applicability”) as the rule that incorporates specified Federal Motor Carrier Safety Regulations. We were not able, during this review, to retrieve the current official AAC R17-5-202 text from the Arizona Secretary of State's site (the official title PDF was blocked by the host).

Intrastate operations and variations

Because we could not independently quote the current official rule text, this page does not list an Arizona-specific weight threshold or DVIR exception. Read the current official text of AAC R17-5-202 and confirm with ADOT how Part 396 applies to intrastate operations in Arizona.

What we could not independently verify from official sources in this review:

Current official text of AAC R17-5-202, including which 49 CFR parts are incorporated and any Arizona-specific intrastate thresholds or exceptions for DVIRs.

Please confirm those points with the state agency linked on this page before relying on them.
