A.    No license as herein provided shall be issued permitting the operation of any motor vehicle to be used as a taxicab until such taxicab shall have been inspected and found to be in good repair and in a clean and sanitary condition, so as to be capable of safely and comfortably transporting passengers therein. The cost, if any, of such inspection shall be paid by the owner of the motor vehicle inspected. The board of public works and safety may cause such taxicab to be inspected at ninety-day intervals, or as often as deemed necessary by the board during the term of such license issued therefor, and for the purpose of such inspection the police department or some person or firm delegated by such police department is authorized to make such inspections and report the same to the board of public works and safety. If upon inspection such taxicab is found in an unsanitary or unsafe condition, such taxicab may be ordered withdrawn from service until placed in a sanitary and serviceable condition, and upon failure to comply with such order the license of such taxicab may be revoked and no portion of the license fee shall be refunded.

    B.    Taxicabs licensed under the provisions of this chapter shall have no fewer than four doors.

    C.    Every taxicab shall be identified by having painted thereon in letters of not less than three inches in height and the name of the owner or the trade name under which he or it does business, and such name shall be painted on each side and on the rear of the taxicab; and whenever the name of the owner or trade name under which he or it does business does not include any of the words "taxicab," "taxi" or "cab," then the word "taxicab" shall be painted on each side and on the rear of the taxicab immediately beneath such name or trade name; and the license number issued for such taxicab shall also in the same manner be painted upon each side and the rear thereof.
