Full-use dealer plates cannot be displayed on vehicles used by the dealership for which purpose?

Full-use dealer plates are specifically designated for vehicles that are part of the dealer's inventory and are primarily intended for purposes like test drives, demonstration rides, and vehicle deliveries to customers. However, when it comes to commercial purposes, the use of full-use dealer plates does not align with their intended application.

The primary function of these plates is to allow for the demonstration and testing of vehicles by prospective buyers, which is integral to the sales process. Commercial use, on the other hand, implies that the vehicle is being used for business operations beyond merely showcasing it to potential customers. This usage typically requires a different type of vehicle registration and licensing, as it could lead to complications with insurance coverage and regulatory compliance.

Therefore, the option regarding commercial purposes aligns with the restrictions placed on full-use dealer plates, emphasizing that these plates are not authorized for vehicles engaged in broader commercial activities.
