This page summarizes what we could verify from official sources about how Maine applies driver vehicle inspection and related vehicle-inspection rules. It is not a complete reprint of Maine law.
Interstate operations
If you operate a commercial motor vehicle in interstate commerce to, from, or through Maine, 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 Maine-specific questions, including how the rules apply to operations that stay entirely inside Maine, contact Maine State Police, Bureau of State Police (Motor Carrier).
What official sources say about state adoption
Official Maine law, 29-A M.R.S. § 555, authorizes the Bureau of State Police to adopt a rule incorporating by reference federal regulations in 49 CFR Parts 40, 382, 383, 385, 390, 391, 392, 393, 395, and 396, as amended, and to adopt amendments to those federal regulations, subject to the procedures in that statute. The bureau may not adopt any rule that exempts motor carriers, vehicles, or drivers transporting hazardous materials of a type or quantity requiring placarding from any federal regulation adopted and incorporated by reference.
Intrastate operations and variations
The statute authorizes incorporation of Part 396; the operative details are in the Bureau’s current adopted rule. We did not independently retrieve that current official rule text during this review. Confirm the current Bureau of State Police motor-carrier safety rule, including any intrastate threshold or DVIR exception, with the Maine State Police and by reading the official adopted rule.
What we could not independently verify from official sources in this review:
- The current official Maine Bureau of State Police rule that actually incorporates 49 CFR Part 396, including any intrastate threshold or DVIR-specific exception.
Please confirm those points with the state agency linked on this page before relying on them.
