(b) The brightness of light emitted from a changeable message sign must not exceed 0.3 foot candles over ambient light levels measured at a distance of one hundred fifty feet (150’) for those sign faces less than or equal to three hundred square feet (300 sq. ft.), measured at a distance of two hundred feet (200’) for those sign faces greater than three hundred square feet (300 sq. ft.) but less than or equal to three hundred eighty-five square feet (385 sq. ft.), measured at a distance of two hundred fifty feet (250’) for those sign faces greater than three hundred eighty-five square feet (385 sq. ft.) and less than or equal to six hundred eighty square feet (680 sq. ft.), measured at a distance of three hundred fifty feet (350’) for those sign faces greater than six hundred eighty square feet (680 sq. ft.), or subject to the measuring criteria in the applicable table set forth in subdivision (h)(4). (c) Any measurements required pursuant to this subsection (h) must be taken from a point within the highway right-of-way at a safe distance from the edge of the traveled way, at a height above the roadway that approximates a motorist’s line of sight, and as close to perpendicular to the face of the changeable message sign as practical. If perpendicular measurement is not practical, valid measurements may be taken at an angle up to forty- five (45) degrees from the center point of the sign face. If measurement shows a level above that prescribed in subdivision (h)(4), the exact calculations must be provided to the sign permit holder. (d) In the event it is found not to be practical to measure a changeable message sign at the distances prescribed in subdivision (h)(2), a measurer may opt to measure the sign at any of the alternative measuring distances described in the applicable table set forth in this subdivision (h)(4). In the event the sign measurer chooses to measure the sign using an alternative measuring distance, the prescribed foot candle level above ambient light must not exceed the prescribed level, to be determined based on the alternative measuring distances set forth in the tables in subdivisions (h)(4)(A), (B), (C), and (D), as applicable. For any measuring distance between the alternative measuring distances set forth in the following tables, the prescribed foot candle level above ambient light must not exceed the interpolated level derived from the following formula: [12 = (D2<2>/01<2>) x 11] Where l1 = the prescribed foot candle level above ambient light for the measuring distance listed in the tables, l2 = the derived foot candle level above ambient light for the desired measuring distance, D1 = the desired measuring distance in feet, and D2 = the alternative measuring distance in feet listed in the tables, as follows: 1.
