These laws may not be current and are often enforced differently by different PD's. In all cases, refer to you local authority for enforcement policies, current laws, rules or regulations. Your current state law is the final authority, not this website! The numbers represent the percentage of light transmitted through the tinted glass, so the lower the number, the darker the film allowed. Generally the films are sold as 5%(limo), 20%(dark), 35%(medium), 50%(light).
S.U.V.s often have different regulations, which are not listed here.

Indiana

IC 9-19-19-4 Sec. 4. (a) This section does not apply to a manufacturer's
tinting or glazing of motor vehicle windows or windshields that is
otherwise in compliance with or permitted by FMVSS205 as promulgated
in 49 CFR 571.205. Proof from the manufacturer, supplier, or installer
that the tinting or glazing is in compliance with or permitted by
FMVSS205 must be carried in the vehicle.
(b) This section does not apply to the driver of a vehicle:
   (1) that is owned by an individual required for medical reasons to be
       shielded from the direct rays of the sun; or
   (2) in which an individual required for medical reasons to be
       shielded from the direct rays of the sun is a habitual passenger.
       The medical reasons must be attested to by a physician licensed to
       practice in Indiana, and the physician's certification of that
       condition must be carried in the vehicle. The physician's certificate
       must be renewed annually.
(c) A person may not drive a motor vehicle that has a:
   (1) windshield;
   (2) side wing;
   (3) side window that is part of a front door; or
   (4) rear back window;

that is covered by or treated with sunscreening material or is tinted to
the extent or manufactured in a way that the occupants of the vehicle
cannot be easily identified or recognized through that window from
outside the vehicle. However, it is a defense if the sunscreening
material applied to those windows has a total solar reflectance of
visible light of not more than twenty-five percent (25%) as measured on
the nonfilm side and light transmittance of at least thirty percent
(30%) in the visible light range.

Notes:

1. Effective Oct 1, 1981 which made front side windows that were too dark
  illegal. The definition of "too dark" was vague and interpretation was
  up to the whim of the police officer.

2. Ammended in 1989 and effective on Jul 1, 1989 to add in specific standards
  on what is too dark based on percentage of light transmission. The rear-back
  window was added into the window tint regulation.

3. Ammended in 1995 through HB1214 sponsored by Rep. L. Jack Lutz, Rep. Gary Cook
  and Senator Adams,  effective Jul 1, 1995 to change the burden of proof
  from the police officer who has to prove the window tint is illegal to
  the driver who has to prove that the window tint is legal.

4. HB1344 sponsored by Rep. Harris would put the burden of proof back on the
  police officer where it belongs. It has died in committee without a hearing.

1       Section 1.  Section 321.438, subsection 2, Code 1995, is
2   amended to read as follows:
3       2.  a.  A Except as provided in paragraph "b", a person
4   shall not operate on the highway a motor vehicle equipped with
5   a front windshield, a side window to the immediate right or
6   left of the driver, or a side=wing forward of and to the left
7   or right of the driver which is excessively dark or reflective
8   so that it is difficult for a person outside the motor vehicle
9   to see into the motor vehicle through the windshield, window,
10   or sidewing sidewings, or side or rear windows which allow for
11   less than seventy percent light tranmittance.  The department
12   shall adopt rules establishing a minimum measurable standard
13   of transparency which shall apply to violations of this
14   subsection.
15       b.  A person suffering from a light=sensitive disorder may
16   operate a motor vehicle equipped with windows with less than
17   seventy percent light transmittance, if that person has made
18   application and has received a waiver of the restriction for
19   the person's motor vehicle and if a light=sensitive disorder
20   permit is properly affixed to the person's motor vehicle.  The
21   department shall waive the restriction and issue an
22   accompanying permit if the applicant files a written statement
23   signed by a licensed vision specialist which certifies that
24   the applicant suffers from a light=sensitive disorder and that
25   it is medically necessary for the person to obtain a waiver of
26   the light transmittance requirements of this subsection.  Any
27   other person operating a motor vehicle with a light=sensitive
28   disorder permit affixed to the motor vehicle shall not be
29   charged with a violation of this section, even though that
30   person does not suffer from a light=sensitive disorder.  As
31   used in this paragraph, "licensed vision specialist" means a
32   physician or osteopath licensed under chapter 148, 150, or
33   150A, or an optometrist licensed under chapter 154.  This
34   exemption does not apply to commercial vehicles or commercial
35   motor vehicles.

EXPLANATION
This bill prohibits a person from operating a motor vehicle with a windshield or other windows which allow for less than 70 percent light transmittance.
This bill allows a person suffering from a light=sensitive disorder to obtain a permit from the state department of transportation allowing the person to operate a motor vehicle with a front windshield, a front side window, or front sidewing with less than 70 percent light transmittance.  The person must make application to the department and present a signed statement from a licensed vision specialist indicating
that it is medically necessary for that person to operate a motor vehicle whose light transmittance is lower than the present requirement.  Any other person operating a motor vehicle with a light=sensitive disorder permit cannot be charged with a violation of section 321.438, subsection 2, even though that person does not suffer from a light=sensitive disorder.  This exemption does not apply to commercial vehicles or commercial motor vehicles.
      A violation of section 321.438 is a scheduled fine of $15. LSB 2305SC 76 js/sc/14

       Windshield wipers.



(1) A windshield in a fixed and upright position, that is equipped with
   safety glazing as required by federal safety-glazing material standards,
   is required on every motor vehicle which is operated on the public
   highways, roads, and streets, except on a motorcycle or implement of
   husbandry.

(2) A person shall not operate a motor vehicle on a public highway, road,
   or street with any sign, sunscreening material, product, or covering
   attached to, or located in or upon the windshield, except the following:

   (a) A certificate or other paper required to be displayed by law;

   (b) Sunscreening material along a strip at the top of the windshield,
       if the material is transparent and does not encroach upon the
       driver's direct forward viewing area as defined in Federal Motor
       Vehicle Safety Standards No. 205 as the AS/1 portion of the
       windshield.

(3) A person shall not operate a motor vehicle required to be registered
   in the Commonwealth, on a public highway, road, or street on which
   vehicle the side wings and side windows on either side forward of or
   adjacent to the operator's seat are composed of, covered by, or treated
   with any sunscreening material or other product or covering which has
   the effect of making the window nontransparent or which would alter the
   window's color, increase its reflectivity, or reduce its light
   transmittance, except as expressly permitted by this section. A
   sunscreening material may be applied to the windows if, when tested on
   one-eighth (1/8) inch clear glass, the material has a total solar
   reflectance of visible light of not more than twenty-five percent (25%)
   as measured on the nonfilm side and a light transmittance of at least
   thirty-five percent (35%) in the visible light range.

(4) A person shall not operate a motor vehicle required to be registered in
   the Commonwealth, on a public highway, road, or street on which vehicle
   any windows behind the driver are composed of, covered by, or treated
   with any sunscreening material, or other product or material which has
   the effect of making the window nontransparent or which would alter the
   window's color, increase its reflectivity, or reduce its light
   transmittance, except as specified below:

   (a) Sunscreen material consisting of film which, when tested on
       one-eighth (1/8) inch clear glass, has a total solar reflectance of
       visible light of not more than thirty-five percent (35%) as measured
       on the nonfilm side and a light transmittance of at least eighteen
       percent (18%) in the visible light range; however, sunscreen material
       which, when tested on one-eighth (1/8) inch clear glass, has a total
       solar reflectance of visible light of not more than thirty-five
       percent (35%) as measured on the nonfilm side and a light
       transmittance of at least eight percent (8%) in the visible light
       range may be used on multipurpose passenger vehicles;

   (b) Perforated sunscreening material which, when tested in conjunction
       with existing glazing or film material, has a total reflectance of
       visible light of not more than thirty-five percent (35%) and a light
       transmittance of no less than thirty percent (30%). For those products
       or materials having different levels of reflectance, the highest
       reflectance from the product or material will be measured by dividing
       the area into sixteen (16) equal sections and averaging the overall
       reflectance. The measured reflectance of any of those sections may
       not exceed fifty percent (50%).

(5) A person shall not operate a motor vehicle required to be registered in
   the Commonwealth, upon a public highway, road, or street, on which
   vehicle the rear window is composed of, covered by, or treated with any
   material which has the effect of making the window nontransparent, unless
   the vehicle is equipped with side mirrors on both sides.

(6) Each installer or seller of sunscreening material shall provide a
   pressure-sensitive, self-destructive, nonremovable, vinyl-type film label
   to the purchaser stating that the material complies with the provisions of
   KRS 189.010(20) to (23) and subsections (1) to (5) of this section. Each
   installer shall affix the required label to the inside left door jamb
   of the motor vehicle. In addition, the label shall state the trade name
   of the material and the installer's or seller's business name. Labeling
   is not required for factory glazing which complies with Federal Motor
   Vehicle Safety Standard No. 205.

(7) Every percentage measurement required by subsections (3) and (4) of this
   section is subject to a tolerance of plus or minus three percent (3%).

(8) A person shall not install window tinting materials on a vehicle that
   fails to meet the minimum standards for light transmission pursuant to
   subsections (3) and (4) of this section. Tinted material that fails to
   meet the minimum standards for light transmission pursuant to
   subsections (3) and (4) of this section shall be removed immediately.

(9) A person who applies sunscreening materials in violation of this section
   shall be guilty upon conviction of a Class B misdemeanor.

(10) Nothing in this section shall prevent the display of a representation
    of the American flag on the rear window of any motor vehicle, including
    any vehicle owned by a local or state government, provided that the
    representation does not exceed a size of five (5) inches by eight (8)
    inches and is placed in a lower corner of the rear window.

(11) The windshield on every motor vehicle shall be equipped with a device
    for cleaning rain, snow or other moisture from the windshield. The device
    shall be so constructed as to be controlled by the operator of the vehicle.

(12) Nothing in this section shall be construed to prevent the use of any
    window which is composed of, covered by, or treated with any material
