the uppermost portion of the windshield if such material does not extend
more than 6 inches down from the top of the windshield.

(a-3) No new or used motor vehicle dealer shall permit a driver to drive a motor vehicle offered for sale or lease off the  premises where the motor vehicle is being offered for sale or lease, including when the driver is test driving the vehicle, with signs, decals, paperwork, or other material on the front  windshield or on the windows immediately adjacent to each side of the driver that would obstruct the driver's view in violation of subsection (a) of this Section. For purposes of this subsection (a-3), "test driving" means when a driver, with permission of the new or used vehicle dealer or employee of the new or used vehicle dealer, drives a vehicle owned and held for sale or lease by a new or used vehicle dealer that the driver is considering to purchase or lease.

(a-5) No window treatment or tinting shall be applied to the windows immediately adjacent to each side of the driver, except:

(1) On vehicles where none of the windows to the rear of the driver's seat are treated

in a manner that allows less than 30% light transmittance, a nonreflective tinted film that allows at least 50% light transmittance, with a 5% variance observed by any law enforcement official metering the light transmittance, may be used on the vehicle windows immediately adjacent to each side of the driver.

(2) On vehicles where none of the windows to the rear of the driver's seat are treated

in a manner that allows less than 35% light transmittance, a nonreflective tinted film that allows at least 35% light transmittance, with a 5% variance observed by any law enforcement official metering the light transmittance, may be used on the vehicle windows immediately adjacent to each side of the driver.

(3) (Blank).
(4) On vehicles where a nonreflective smoked or tinted glass that was originally

installed by the manufacturer on the windows to the rear of the driver's seat, a nonreflective tint that allows at least 50% light transmittance, with a 5% variance observed by a law enforcement official metering the light transmittance, may be used on the vehicle windows immediately adjacent to each side of the driver.

(a-10) No person shall install or repair any material prohibited by subsection (a) of this Section.
(1) Nothing in this subsection shall prohibit a person from removing or altering any

material prohibited by subsection (a) to make a motor vehicle comply with the requirements of this Section.

(2) Nothing in this subsection shall prohibit a person from installing window treatment

for a person with a medical condition described in subsection (g) of this Section. An installer who installs window treatment for a person with a medical  condition described in subsection (g) must obtain a copy of the certified statement or letter written by a physician described in subsection (g) from the person with the medical condition prior to installing the window treatment. The copy of the certified statement or letter must be kept in the installer's permanent records.

the driver which materially obstructs the driver's view.

(d) Every motor vehicle, except motorcycles, shall be equipped with a
device, controlled by the driver, for cleaning rain, snow, moisture or other
obstructions from the windshield; and no person shall drive a motor vehicle

mirrors, which materially obstructs the driver's clear view of the highway.

(e) No person shall drive a motor vehicle when the windshield, side or
rear windows are in such defective condition or repair as to materially
impair the driver's view to the front, side or rear.  A vehicle equipped
with a side mirror on each side of the vehicle which are in conformance
with Section 12-502 will be deemed to be in compliance in the event the
rear window of the vehicle is materially obscured.

(f) Subsections (a), (a-5), (b), and (b-5) of this Section shall not apply to:

(1) is owned and operated by a person afflicted with or suffering from a medical

disease, including, but not limited to, systemic or discoid lupus erythematosus, disseminated superficial actinic porokeratosis, light sensitivity as a result of a traumatic brain injury, or albinism, which would require that person to be shielded from the direct rays of the sun; or

However, no exemption from the requirements of subsection (a-5) shall be granted for any condition for which protection from the direct rays of the sun can be adequately obtained by the use of sunglasses or other eye protective devices.

Such certification must be carried in the motor vehicle at all times. The certification

shall be legible and shall contain the date of issuance, the name, address and signature of the attending physician, and the name, address, and medical condition of the person requiring exemption.  The information on the certificate for a window treatment must remain current and shall be renewed every 4 years  by the attending physician.  The owner shall also submit a copy of the certification to the Secretary of State. The Secretary of State may forward notice of certification to law enforcement agencies.

Section shall be guilty of a petty offense and fined no less than $50 nor more
than $500.  A second or subsequent violation of subsection (a), (a-3), (a-5), (a-10), (b), (b-5), or (g-7) of
this Section shall be treated as a Class C misdemeanor and the violator fined
no less than $100 nor more than $500.  Any person convicted  under subsection
(a), (a-5), (b), or (b-5) of this Section shall be ordered to alter any
nonconforming windows into compliance with this Section.

(k) Except as provided in subsection (a-3) of this Section, nothing in this
Section shall create a cause of action on behalf of a buyer against a
