The boards shall be well supported, and shall be placed so as to be easily seen by travelers and not to obstruct travel, and shall contain on each side, in capital letters at least five (5) inches high, the words “Railroad Crossing.”

(2) No person shall erect on or near a public highway any signboard or other contrivance similar to or like the danger signals used by railroads, interurbans and electric railway companies at road crossings.
