Subd. 2. Windshield wiper. The windshield on every motor vehicle shall be equipped with a device for cleaning rain, snow or other moisture from the windshield, which device shall be so constructed as to be controlled or operated by the driver of the vehicle.

Subd. 3. Defrosting requirement. No person shall drive any motor vehicle with the windshield or front side windows covered with steam or frost to such an extent as to prevent proper vision.

Subd. 4. Glazing material; prohibitions and exceptions. (a) No person shall drive or operate any motor vehicle required to be registered in the state of Minnesota upon any street or highway under the following conditions:

(1) when the windshield is composed of, covered by, or treated with any material which has the effect of making the windshield more reflective or in any other way reducing light transmittance through the windshield;

(2) when any window on the vehicle is composed of, covered by, or treated with any material that has a highly reflective or mirrored appearance;

(3) when any side window or rear window is composed of or treated with any material so as to obstruct or substantially reduce the driver's clear view through the window or has a light transmittance of less than 50 percent plus or minus three percent in the visible light range or a luminous reflectance of more than 20 percent plus or minus three percent; or

(4) when any material has been applied after August 1, 1985, to any motor vehicle window without an accompanying permanent marking which indicates the percent of transmittance and the percent of reflectance afforded by the material. The marking must be in a manner so as not to obscure vision and be readable when installed on the vehicle.
