Any rescue squad, volunteer fire department, or charitable or eleemosynary organization in this State may solicit funds from motorists on highways and streets located within a municipality with a permit issued by the governing body of the municipality or within the unincorporated areas of a county with a permit issued by the governing body of the county. The governing body may grant or deny a permit. Permits may be issued for more than one day but no organization may be issued more than two permits in any one calendar year. Permits may impose limits upon solicitation as the governing body of the municipality or county determines are necessary to protect the health and safety of motorists, pedestrians, and those soliciting for an organization and to ensure that solicitation does not unreasonably impede the flow of traffic. The governing body issuing the permit shall have responsibility for supervising the solicitation and enforcing the terms of the permit; provided, that the municipality or county is immune from liability as provided in the Tort Claims Act for any loss or injury occurring as a result of these solicitations.
