What document must be submitted with the completed application for an inspection station permit?

The correct answer relates to the requirement for submitting a maintenance agreement copy along with the completed application for an inspection station permit. In Missouri, the maintenance agreement is crucial because it outlines the responsibilities and procedures the inspection station will follow to ensure compliance with regulations. This document serves as a formal commitment to maintaining the equipment and standards required for vehicle inspections. It ensures that the station will be properly serviced and monitored to uphold safety and quality standards for automotive inspections.

In terms of context, the other options, while they may seem relevant, do not specifically pertain to the permit application process for an inspection station in Missouri. A vehicle inspection report is typically generated after an inspection has taken place, proof of insurance is important for operating a business but is not the primary requirement for a permit application, and a financial statement might provide an overview of the business's financial health but is not essential for the permit process specifically.
