No person may drive or operate any bus of a transportation system for the transportation of passengers within any city or town in this state, where the operation of such bus is subject to regulation by the authorities of such city or town under Section 21-27-121, unless he shall first have been licensed so to do as follows: he shall make application to the mayor of such municipality in writing, accompanied by a statement of some reputable citizen thereof, that the applicant is over the age of eighteen years, an experienced driver, of good moral character, and physically and mentally capacitated to drive and operate such motor vehicle. The mayor shall place such application before the board of aldermen, or other governing authorities, whereupon inquiry may be made by such governing authorities into the moral character and mental and physical fitness of the applicant. If the permit shall be granted the applicant shall receive a license, signed by the mayor, together with a metallic badge, which shall have a number and the name of the municipality thereon, and which shall be worn so that the same will be displayed while engaged in or about such occupation.
