Can depot plates be used during normal business hours to transport a motor vehicle?

The correct interpretation of the use of depot plates during normal business hours is that they can be utilized for any business-related transportation. This reflects the primary purpose of depot plates, which are typically designed to facilitate the movement of vehicles in connection with business activities. As long as the transportation is directly related to the business's operations, using depot plates during regular hours aligns with their intended use.

In contrast, the other options suggest limitations or conditions that do not commonly apply to depot plate usage in general business contexts. For instance, implying that depot plates can only be used within a specific distance unnecessarily constrains their application. The suggestion that they can only be used outside of business hours misrepresents their functionality. Moreover, the need for prior approval in specific situations is not a standard requirement for the general usage of depot plates when used in a business context. Thus, option C accurately reflects the broad and practical use of depot plates for business purposes during normal operating hours.
