§ 25.4. Glare control on roadways.

A.

Glare from luminaires. It shall be unlawful to place or maintain on private property any luminaire of such intensity or brilliance within the field of view of a driver so as to impair his/her vision upon the public roadway, or to interfere otherwise with the operation of a motor vehicle. Every reasonable effort shall be made to ensure that the brilliance of any luminaire less than ten degrees from a passenger car driver's line of sight; either along the roadway ahead or toward each traffic control device, sign, or signal; does not exceed the brilliance of a headlight on an oncoming passenger car whose extended center line lies ten feet to the driver's left, when the car is between 60 and 100 feet from the driver, and when the lowermost distribution of light from the headlight is in use.

B.

Reflected solar glare. No building of more than one story, on which glass constitutes more than one quarter of a side, shall be constructed, until the orientations for the glass have been selected which will avoid sunlight reflections within ten degrees of the driver's field of view upon any public roadway. The orientations for the glass shall account for the bearing and altitude angles of the sun at all times of day on all days of the year.
