In this regulation, “dealer registration plate” means an interchangeable metal license plate used by licensed vehicle dealers, manufacturers, distributors, and factory branches. Display of Dealer Registration Plates by Licensed Dealers. A dealer registration plate may be displayed on a vehicle owned by a licensed dealer and used mainly for the dealer’s business purposes.

An owner, partner, or officer of the corporation who is listed on the application for a vehicle dealer’s license or any employee of the dealership may operate a vehicle displaying a dealer registration plate, subject to the other conditions of this regulation. A dealer registration plate may be displayed on a vehicle owned by the dealership and operated by a prospective buyer for demonstration purposes for a period of not more than 10 days, provided the prospective buyer has written authorization from the dealership for any use of the vehicle exceeding 1 day. A dealer registration plate may be displayed on a vehicle owned by the dealership and loaned to an educational institution as set forth in Transportation Article, §13-621, Annotated Code of Maryland.
