§ 31-5-962 — Sunscreening devices

(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.
