Dealer license plates may be used on which of the following?

Dealer license plates are specifically designed for use on vehicles that are part of a dealer's inventory. This allows dealerships to operate and display their inventory legally without needing to register each vehicle individually in a customer's name. The intent behind dealer plates is to facilitate test drives, demonstration purposes, or transport of vehicles to and from different locations related to the business, making option B the correct choice.

Using dealer plates on personal vehicles of employees, vehicles owned by customers, or any vehicle temporarily does not align with the regulations governing dealer plates. Those options reflect scenarios that fall outside the permitted use of dealer plates, as they are intended exclusively for inventory vehicles owned by the dealer themselves. The focused use on dealer inventory helps maintain accountability and oversight within the dealership's operations.
