43 Tex. Admin. Code § 21.451 – Spacing Requirements

(a) An off-premise sign having 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 roadway.
(b) An off-premise sign having a face area of at least 100 but less than 301 square feet may not be erected within 500 feet of another off-premise sign on the same side of the roadway.
(c) An off-premise sign having 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 roadway.
(d) Signs located at the same intersection are not in violation of these spacing rules because of their nearness to one another if they are located so that their messages are directed toward traffic flowing in different directions and if they are not visible from the main-traveled way of an interstate or federal-aid primary highway.
(e) For spacing purposes, all measurements shall be made along the nearest edge of the highway right-of-way and shall be made from the midpoint of the sign structure nearest such right-of-way.
(f) No off-premise sign may be erected within five feet of any rural road right-of-way line.
(g) An off-premise sign may only be erected within 800 feet of at least one recognized commercial or industrial activity, or the office of a governmental entity. The commercial or industrial activity or office building must be on the same side of the rural road as the sign.
(h) Signs may not be located in such a manner as to create a safety hazard. They shall not be so located as to be likely to cause a driver to be unduly distracted in any way or so as to obscure or otherwise interfere with the effectiveness of an official traffic sign, signal, or device, or obstruct or interfere with the driver's view of approaching, merging, or intersecting traffic whether the intersection be of two or more roads or the intersection of a road with a railroad.
