Miss. Code § 27-71-15
Except as otherwise provided in Section 67-9-1 for the transportation of limited amounts of alcoholic beverages for the use of an alcohol processing permittee, if transportation requires passage through a county which has not authorized the sale of alcoholic beverages, such transportation shall be by a sealed vehicle. Such seal shall remain unbroken until the vehicle shall reach the place of business operated by the permittee. The operator of any vehicle transporting alcoholic beverages shall have in his possession an invoice issued by the commission at the time of the wholesale sale covering the merchandise transported by the vehicle. The commission is authorized to issue regulations controlling the transportation of alcoholic beverages.
When the restrictions imposed by this section and by the regulation of the commission have not been violated, the person transporting alcoholic beverages through a county wherein the sale of alcoholic beverages is prohibited shall not be guilty of unlawful possession and such merchandise shall be immune from seizure.
