Section 445.4 - Signs in zoned or unzoned commercial or industrial areas

(i) The maximum area for one sign shall be 1200 square feet with a maximum height of 30 feet and maximum length of 60 feet, inclusive of a border and trim but excluding the base or apron, supports and other structural members.

(ii) The area shall be measured by the smallest square, rectangle, triangle, circle or combination thereof which will encompass the entire sign.

(iii) A sign structure may contain one or two signs per facing and may be placed double-faced, back to back or V-type.

(iv) Signs which exceed 600 square feet in area may not be double-faced (abutting and facing the same direction).

(i) Along the interstate system and limited access highways on the primary system, no two sign structures may be spaced less than 500 feet apart; and outside the boundaries of cities of all classes and boroughs, no structure may be erected adjacent to or within 500 feet of an interchange or safety rest area, measured along the interstate or limited access primary from the beginning or ending of pavement widening at the exit from or entrance to the main-traveled way.

(ii) Along nonlimited access highways on the primary system, no two structures shall be spaced less than 300 feet apart if outside cities of all classes and boroughs, nor less than 100 feet apart if within the cities and boroughs.

(iii) These spacing provisions do not apply to sign structures separated by a building or other obstruction in such a manner that only one sign facing located within these spacing distances is visible from the highway at any one time.

(iv) Official and on-premise signs may not be counted nor may measurements be made from them for purposes of determining spacing requirements.

(v) The distance between sign structures shall be measured along the nearest edge of the pavement between points directly opposite the signs along the same side of the traveled way.

(i) A sign may not be permitted which is not effectively shielded so as to prevent beams or rays of light from being directed at a portion of the traveled ways of the interstate or primary systems or which is of such intensity or brilliance as to cause glare or to impair the vision of the driver of a vehicle, or which interferes with a driver's operation of a motor vehicle.

(ii) A sign may not be so illuminated that it interferes with the effectiveness of or obscures an official traffic sign, device or signal.

(iii) Lighting of signs shall be subject to other provisions relating to lighting of signs along highways under the jurisdiction of the Department.

(iv) Signs which contain, include or are illuminated by a flashing, intermittent or moving light or lights shall be prohibited, except those giving public service information such as time, date, temperature, weather or similar information.

(i) Signs may not be erected or maintained in such a manner as to obscure or otherwise physically interfere with an official traffic sign, signal or device or to obstruct or physically interfere with the driver's view of approaching, merging or intersecting traffic.

(ii) Signs may not be erected or maintained which imitate or resemble any official traffic sign, signal or device.

(iii) Signs may not be erected or maintained upon trees or painted or drawn upon rocks or natural features.

(iv) Signs which are structurally unsafe may not be erected or maintained. If a sign is determined by the Department to be structurally unsafe, a reasonable time will be accorded the owner to make necessary repairs. If necessary repairs are not made within a reasonable time following notice given by the Department, the signs will be subject to removal by the Department under section 10 of the act (36 P. S. § 2718.110).
