Texas Transportation Code - TRANSP § 394.045. Space Between Signs

(a) An off-premise sign that has a face area of 301 square feet or more may not be erected within 1,500 feet of another off-premise sign on the same side of the road.

(b) An off-premise sign that has a face area of 100 or more but less than 301 square feet may not be erected within 500 feet of another off-premise sign on the same side of the road.

(c) An off-premise sign that has a face area of less than 100 square feet may not be erected within 150 feet of another off-premise sign on the same side of the road.

(d) A sign located at the same intersection where one or more other signs are located does not violate this section because of its proximity to another sign if each of the signs is located so that the sign's message is directed toward the traffic flowing in a direction different from the traffic toward which any other sign's message is directed.

(e) In this section, for purposes of measuring distance between signs, each double-faced, back-to-back, or V-type sign is a single sign.
