Kentucky DVIR and vehicle inspection rules

Last reviewed November 12, 2026.

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

Interstate operations

If you operate a commercial motor vehicle in interstate commerce to, from, or through Kentucky, 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 Kentucky-specific questions, including how the rules apply to operations that stay entirely inside Kentucky, contact Kentucky State Police and Kentucky Transportation Cabinet.

What official sources say about state adoption

The official Kentucky Administrative Regulations include 601 KAR 1:005, which is the state’s regulation on adoption of federal motor carrier safety regulations. During this review we identified that official regulation on the Legislative Research Commission site, but we did not independently retrieve and quote its full current text here.

Intrastate operations and variations

Read the current official text of 601 KAR 1:005 for which 49 CFR parts Kentucky adopts and for any intrastate modifications. Confirm coverage, weight thresholds, and any DVIR exceptions with Kentucky State Police or the Kentucky Transportation Cabinet. This page does not invent those details.

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

The current full official text of 601 KAR 1:005, including any Kentucky-specific vehicle threshold or DVIR exception.

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