(1) A person shall not drive a motor vehicle with any of the following:
(a) A sign, poster, nontransparent material, window application, reflective film, or nonreflective film upon or in the front windshield, the side windows immediately adjacent to the driver or front passenger, or the sidewings adjacent to and forward of the driver or front passenger, except that a tinted film may be used along the top edge of the windshield and the side windows or sidewings immediately adjacent to the driver or front passenger if the material does not extend more than 4 inches from the top of the windshield, or lower than the shade band, whichever is closer to the top of the windshield.
(b) A rear window or side window to the rear of the driver composed of, covered by, or treated with a material that creates a total solar reflectance of 35% or more in the visible light range, including a silver or gold reflective film.
(c) A dangling ornament or other suspended object that obstructs the vision of the driver of the vehicle, except as authorized by law.
(2) A person shall not drive a motor vehicle if driver visibility through the rear window is obstructed, unless the vehicle is equipped with 2 rearview mirrors, 1 on each side, adjusted so that the operator has a clear view of the highway behind the vehicle.
(3) This section shall not apply to:
(a) The use of draperies, louvers, or other special window treatments, except those specifically designated in this section, on the rear window, or a side window to the rear of the driver if the vehicle is equipped with 2 outside rearview mirrors, 1 on each side, adjusted so that the driver has a clear view of the highway behind the vehicle.
(b) The use of a nonreflective, smoked or tinted glass, nonreflective film, perforated window screen, or other decorative window application on the rear window or a side window to the rear of the driver.
(c) The placement of a necessary certificate or sticker that does not obstruct the driver's clear view of the roadway or an intersecting roadway.
(d) A vehicle registered in another state, territory, commonwealth of the United States, or another country or province.
(e) A special window treatment or application determined necessary by a physician or optometrist, for the protection of a person who is light sensitive or photosensitive, if the owner or operator of a motor vehicle has in possession a letter signed by a physician or optometrist, indicating that the special window treatment or application is a medical necessity. However, the special window treatment or application shall not interfere with or obstruct the driver's clear vision of the highway or an intersecting highway.
(4) Except as provided in subsection (5), the windshield on each 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. A vehicle licensed as an historical vehicle is exempt from this subsection if the vehicle was not originally equipped with such a device. Each windshield wiper upon a motor vehicle shall be maintained in good working order.
(5) A truck with a gross weight over 10,000 pounds, a truck tractor, a bus, or a truck regardless of weight carrying hazardous materials on which a placard is required to be posted pursuant to 49 C.F.R. parts 100 to 199 having a windshield shall be equipped with not less than 2 automatically operating windshield wiper blades, 1 on each side of the centerline of the windshield, for cleaning rain, snow, or other moisture from the windshield. The blades shall be in such condition as to provide clear vision for the driver, unless 1 blade is so arranged as to clean an area of the windshield extending to within 1 inch of the limit of vision through the windshield at each side. However, in driveaway-towaway operations, this subsection shall apply only to the driven vehicle. In addition, 1 windshield wiper blade suffices under this subsection when the driven vehicle in a driveaway-towaway operation constitutes part or all of the property being transported and has no provision for 2 blades. A truck and truck tractor, manufactured after June 30, 1953, that depends upon vacuum to operate the windshield wipers, shall be so constructed that the operation of the wipers is not materially impaired by change in the intake manifold pressure.
(6) A truck with a gross weight over 10,000 pounds, a truck tractor, a bus, or a truck regardless of weight carrying hazardous materials on which a placard is required to be posted pursuant to 49 C.F.R. parts 100 to 199 shall not be operated on the highways at any time unless it is equipped with a hot air windshield defroster or an electrically heated windshield or other device to heat and maintain the windshield in operable condition at all times.
