No unmarked law-enforcement vehicle, herein exempted, may engage in routine traffic stops.

(b) A sun-screening device when used in conjunction with the windshield must be nonreflective and may not be red, yellow or amber in color. A sun-screening device may be used only along the top of the windshield and may not extend downward beyond the ASI line or more than five inches from the top of the windshield whichever is closer to the top of the windshield.

(c) A sun-screening device when used in conjunction with the automotive safety glazing materials of the side wings or side windows located at the immediate right and left of the driver shall be a nonreflective type with reflectivity of not more than twenty percent and have a light transmission of not less than thirty-five percent. The side windows behind the driver and the rear most windows may have a sun-screening device that is designed to be used on automotive safety glazing materials that has a light transmission of not less than thirty-five percent and a reflectivity of not more than twenty percent. If a sun-screening device is used on glazing behind the driver, one right and one left outside rear view mirror is required.

(d) Each manufacturer shall:

(1) Certify to the West Virginia State Police and Division of Motor Vehicles that a sun-screening device used by it is in compliance with the reflectivity and transmittance requirements of this section;

(2) Provide a label not to exceed one and one-half square inches in size, with a means for the permanent and legible installations between the sun-screening material and each glazing surface to which it is applied that contains the manufacturer's name and its percentage of light transmission; and

(3) Include instructions with the product or material for proper installation, including the affixing of the label specified in this section. The labeling or marking must be placed in the left lower corner of each glazing surface when facing the vehicle from the outside.

The affidavit must be in the possession of the person so afflicted, or the person's legal guardian, at all times while being transported in the motor vehicle.
