It shall be the duty of every person, firm, or corporation engaged in the business of plumbing as a master plumber to display his or her certificate of license/registration number on all vehicles while engaged in the business of plumbing as a master plumber. These numbers shall be attached in a legible manner in contrasting colors on both sides of said vehicles with not less than two-inch block numerals. When a vehicle displaying a license/registration number is no longer used in the master plumber's plumbing business, or in the event the master plumber's license/registration expires or is revoked, the master plumber shall either remove the license/registration number from the vehicle or paint over the license/registration number with an opaque paint so that the license/registration number can no longer be seen.
