The Board may issue a license for a licensed motor vehicle dealer to display for sale or sell vehicles at locations other than his established place of business, subject to compliance with local ordinances and requirements. A license issued pursuant to this section shall not be required for a licensed motor vehicle dealer to display for sale or sell vehicles at wholesale auction; placing vehicles for sale at a wholesale auction shall not be considered a consignment. A permanent supplemental license may be issued for premises less than 500 yards from the dealer’s established place of business, provided a sign is displayed as required for the established place of business. A supplemental license shall not be required for premises otherwise contiguous to the established place of business except for a public thoroughfare. A temporary supplemental license may be issued for a period not to exceed seven days, or 14 days for trailers and motorcycles, provided that the application is made 15 days prior to the sale. The Board shall not issue a temporary supplemental license (i) for the same jurisdiction for a consecutive seven-day period or (ii) for motorcycles for a consecutive 14-day period. The Board shall not issue more than eight supplemental licenses per year to any licensed motor vehicle dealer. A temporary supplemental license for the sale of new motor vehicles may be issued only for locations within the dealer’s area of responsibility, as defined in his franchise or sales agreement, unless proof is provided that all dealers in the same line-make in whose areas of responsibility, as defined in their franchise or sales agreements, where the temporary supplemental license is sought do not oppose the issuance of the temporary license. A temporary supplemental license for sale of used motor vehicles may be issued only for the county, city, or town in which the dealer is licensed pursuant to § 46.2-1510, or for a contiguous county, city, or town. Temporary licenses may be issued without regard to the foregoing geographic restrictions where the dealer operating under a temporary license provides notice by certified mail, at least 30 days before any proposed sale under a temporary license, to all other dealers licensed in the jurisdiction in which the sale will occur of the intent to conduct a sale and permits any locally licensed dealer who wishes to do so to participate in the sale on the same terms as the dealer operating under the temporary license. Any locally licensed dealer who chooses to participate in the sale must obtain a temporary supplemental license for the sale pursuant to this section. The dealer operating under a temporary license shall provide to the Board a copy of the notice required under this section and a list of the dealers to whom the notice was distributed. A temporary supplemental license for sale of used motor vehicles that are late model vehicles as defined by § 46.2-1600 at a new motor vehicle show that is sponsored by a statewide or local trade association of franchised dealers and held within the geographic area of the dealer members of such association may be issued without regard to the foregoing geographic restrictions or notification and approval provisions, provided that the applicant is lawfully participating in such new motor vehicle show. A temporary supplemental license may be issued for the sale of boat trailers at a boat show. Any such license shall be valid for no more than 14 days. Application for such a license shall be made and such license obtained prior to the opening of the show. Temporary supplemental licenses for sale of boat trailers at boat shows may be issued for any boat show located anywhere in the Commonwealth without notification of or approval by other boat trailer dealers.
