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

Interstate operations

If you operate a commercial motor vehicle in interstate commerce to, from, or through New Hampshire, 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 New Hampshire-specific questions, including how the rules apply to operations that stay entirely inside New Hampshire, contact New Hampshire State Police, Department of Safety.

What official sources say about state adoption

Official New Hampshire law includes RSA 266:72-a, which addresses motor carriers, equipment, and roadside inspections and authorizes adoption of federal motor carrier regulations. During this review we identified that official statute, but we did not independently retrieve and quote its full current text, or the current official Department of Safety rule, here.

Intrastate operations and variations

Read the current official text of RSA 266:72-a and the Department of Safety’s current adopted motor-carrier safety rules for how New Hampshire applies Part 396. Confirm any intrastate threshold or DVIR exception with New Hampshire State Police. 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 RSA 266:72-a and the current official New Hampshire rule adopting 49 CFR Part 396, including any intrastate threshold or DVIR exception.

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