The commissioner is authorized to make use of the facilities and property upon which are located inspection stations, as prescribed in Sections 27-5-71 and 27-5-73, for the purpose of commercial driver's license testing sites under the Mississippi Commercial Driver's License Law. The State Tax Commission shall cooperate with the Commissioner of Public Safety in making such property and facilities available for such use; however, the use of the inspection stations by the Commissioner of Public Safety shall not unreasonably interfere with the duties of the State Tax Commission.
