Miss. Code § 21-37-31
The governing authorities of any municipality, excepting those in counties bordering on the Gulf of Mexico with a population of more than 80,000, are hereby authorized and empowered to permit the placing of advertising signs upon parking meters or parking meter posts and to contract with any individual or company for the rental or lease thereof, as they may find advantageous to the municipality. The signs shall be placed in compliance with rules and regulations set out by the governing authorities of the municipality, and shall be placed in such manner so as to not obstruct the view of the street, the operation of the meters, or endanger the cars or the drivers thereof parking in front of or near the meters, or pedestrians using the sidewalks upon which the meters are located. The governing authorities shall require any person placing advertising signs upon parking meters or parking meter posts to enter into such contracts of insurance as may be necessary to protect the municipality or any person from any loss or damage caused by the presence of the advertising signs. All monies received by the municipality pursuant to the contract of lease or rental entered into shall be placed in the general fund of the city and expended for such purposes as may be authorized by law.
