(a) The bottom edge of the material is at least twenty-nine inches above the undepressed driver’s seat when measured from a point five inches in front of the bottom of the backrest with the driver’s seat in its rearmost and lowermost position with the vehicle on a level surface.
(b) The material is not red or amber in color.
12. Safety monitoring equipment and driver feedback if mounted in either of the following locations:
(a) Immediately behind, slightly above or slightly below the rearview mirror.

Except as otherwise provided in this section, a person shall not operate a motor vehicle with an object or material placed, displayed, installed, affixed or applied on the windshield or side or rear windows or with an object or material placed, displayed, installed, affixed or applied in or on the motor vehicle in a manner that obstructs or reduces a driver’s clear view through the windshield or side or rear windows.
C. Except as otherwise provided in this section, a person shall not place, install, affix or apply a transparent material on the windshield or side or rear windows of a motor vehicle if the material alters the color or reduces the light transmittance of the windshield or side or rear windows.
D. Each manufacturer shall certify to the director that the product or material the manufacturer manufactures or assembles complies with the reflectivity and transmittance requirements of this section.
E. This section does not allow or prohibit the use and placement of federal, state or local certificates on any window as are required or prohibited by applicable laws.
F. A person who sells or installs objects or materials under this section shall set forth in a conspicuous manner that the installation of the object or material to the driver or passenger side window may be illegal in some states.

H. In this section, unless the context otherwise requires:
1. "Light transmission" means the ratio of the amount of total light, expressed in percentages, that is allowed to pass through the product or material including the glazing to the amount of total light falling on the product or material and the glazing.
2. "Luminous reflectance" means the ratio of the amount of total light, expressed in percentages, that is reflected outward by the product or material to the amount of total light falling on the product or material.
3. "Manufacturer" means either:
(a) A person who engages in the manufacturing or assembling of sun screening products or materials designed to be used in conjunction with vehicle glazing materials.
(b) A person who fabricates, laminates or tempers the glazing material incorporating the capacity to reflect or to reduce the transmittance of light during the manufacturing process.
