What is the purpose of depot plates during normal business hours?

The correct answer focuses on the role of depot plates, which are specifically designed for the transportation of motor vehicles. Depot plates are typically issued to dealerships and allow for the movement of vehicles that are not yet registered or have not been assigned permanent license plates. This facilitates the delivery and transfer of vehicles to and from the dealership without the need for individual registration of each vehicle being moved for business use, thus enabling more efficient operations during normal business hours.

In this context, other options do not accurately reflect the primary function of depot plates. Personal use of a vehicle would not fall under the intended purpose of depot plates, as they are meant strictly for business-related transportation of vehicles. Storing vehicles at the dealership or providing access to repair facilities, while relevant to dealership operations, do not align with the specific utility of depot plates as they pertain to legal vehicle transport within business activities.
