When can plates be transferred from a customer's vehicle to an inventory vehicle using DMV form VSA 39?

The correct response indicates that plates can be transferred from a customer’s vehicle to an inventory vehicle using DMV form VSA 39 specifically when the customer’s vehicle is in the dealer’s shop for service. This situation allows for a temporary reassignment of the license plates while the original vehicle is being worked on. The transfer of plates in this scenario is permitted under Virginia law and is seen as a way to facilitate service work and maintain legal compliance concerning vehicle registration and licensing.

In contrast, the other options do not conform to the regulatory guidelines. Transferring plates solely based on a customer request or only during a sale doesn’t provide the specific context required for such a transfer. Additionally, stating that plates can be transferred "whenever needed" lacks the necessary specificity and structure defined by the laws governing vehicle plate transfers. Adhering to the designated circumstances outlined in option A ensures both compliance with DMV regulations and the protection of customers' registrations during vehicle servicing.
