WY Stat § 31-5-962 (1997 through Reg Sess) What's This?

(a) As used in this section:

(i) "Dealer" means any person or business engaged in the distribution or installation of sunscreening products or materials designed to be used in conjunction with vehicle glazing materials for the purpose of reducing the effects of the sun;

(ii) "Light transmission" means the ratio of the amount of total light to pass through a product or material to the amount of the total light falling on the product or material;

(iii) "Luminous reflectance" means the ratio of the amount of total light that is reflected outward by the product or material to the amount of the total light falling on the product or materials;

(iv) "Multipurpose passenger vehicle" means a motor vehicle designed to carry ten (10) persons or less which is constructed either on a truck chassis or with special features for occasional off-road operation;

(v) "Nonreflective" means a product or material designed to absorb light rather than to reflect it;

(vi) "Sunscreening device" means film material or device that is designed to be used in conjunction with motor vehicle safety glazing materials for reducing the effects of the sun.

(b) No person may operate an enclosed motor vehicle that is registered or required to be registered in this state on any public highway, road or street that has a sunscreen device on the windshield, the front side wings and side windows adjacent to the right and left of the driver and windows adjacent to the rear of the driver that do not meet the requirements of this section.

(c) A sunscreening device when used in conjunction with the windshield shall be a nonreflective type and may not be red, yellow or amber in color. A sunscreening device may be used only along the top of the windshield and may not extend downward beyond the AS-1 line or more than five (5) inches from the top of the windshield, whichever is closer to the top of the windshield.

(d) A sunscreening device, when used in conjunction with the safety glazing materials of the side wings or side windows, or both, located at the immediate right and left of the driver, shall be a nonreflective type and have total light transmission through both the sunscreening device and glazing of not less than twenty-eight percent (28%).

(e) A sunscreening device, when used in conjunction with the safety glazing materials of the side windows behind the driver and the rearmost window, shall be a nonreflective type and have total light transmission through both the sunscreening device and glazing of not less than twenty-eight percent (28%).

(f) No sunscreening device or tinting film may be applied or affixed to any window of a motor vehicle that has a luminous reflectance of light exceeding twenty percent (20%).

(g) If any sunscreen device or tinting film is added to any windows behind the operator, one (1) left and one (1) right outside rearview mirror shall be required.

(h) The requirements of this section shall not apply to windows behind the driver of trucks, buses, motor homes, ambulances, limousines and multipurpose passenger vehicles, to windshields on motorcycles or motor-driven cycles. Except as provided in subsection (j) of this section, vehicle windows with a sunscreen device or tinting film applied prior to July 1, 1996 which do not meet the specifications established by this section shall be in violation after December 31, 1996.

(j) Notwithstanding the requirements of subsections (d) and (e) of this section, any sunscreening device applied prior to July 1, 1996, when used in conjunction with the safety glazing materials of the side wings or side windows located at the immediate right and left of the driver, the side windows behind the driver and the rearmost window shall be of a nonreflective type and have total light transmission through both the sunscreening device and the glazing of not less than thirteen percent (13%).

(k) No person or firm may apply or affix to the windows of any motor vehicle in this state, a sunscreen device or tinting film that is not in compliance with the requirements of this section.

(m) Notwithstanding the requirements of this section, a motor vehicle operated by or regularly used to transport any person with a medical condition which renders him susceptible to harm or injury from exposure to sunlight or bright artificial light may be equipped, on its windshield and any or all of its windows, with sun shading or tinting films or applications which reduce the transmission of light into the vehicle to levels not less than twenty-five percent (25%). The sun shading or tinting film when applied to the windshield of a motor vehicle shall not cause the total light transmittance to be reduced to any level less than seventy percent (70%), except for the upper five (5) inches of the windshield or the AS-1 line, whichever is closer to the top of the windshield. Vehicles equipped with sun shading or tinting films as provided in this subsection shall not be operated on any highway unless the driver or an occupant of the vehicle has in his possession a certificate issued by the director authorizing such operation. The director shall issue the certificate only upon receipt of a signed statement from a licensed physician or licensed optometrist identifying the person seeking the certificate and stating that, in the physician's or optometrist's professional opinion, the equipping of a vehicle with sun shading or tinting films or applications is necessary to safeguard the health of the person seeking the certificate. Certificates issued by the director under this subsection shall be valid so long as the condition requiring the use of sun shading or tinting films or applications persists or until the vehicle is sold, whichever first occurs. In the discretion of the director, one (1) or more certificates may be issued to an individual or a family.

(n) This section shall apply to multipurpose vehicles as defined in W.S. 31-1-101(a)(xv)(M) when equipped with a windshield and an enclosed cab.
