Window Tint
IC 9-19-19-4 — light transmittance of at least 30 percent on the windshield, front side and rear windows
No one drives a motor vehicle whose windshield, side wing, front door side window or rear back window is covered or treated with material that has a total solar reflectance of visible light of more than 25 percent, or a light transmittance of less than 30 percent. Any allowed windshield treatment is on the uppermost part only, no lower than the AS-1 line.
Who handles this in Indiana: legal aid programs and the state offices, listed in the Indiana directory.
A vehicle may be stopped to check its tint, but the vehicle, its contents, its driver and its passengers may not be inspected, searched or detained solely because of a tint violation.
- A driver of a vehicle owned by, or habitually carrying, someone who for medical reasons must be shielded from the sun is exempt, with a certificate from a physician or optometrist licensed in Indiana carried in the vehicle and renewed annually.
- Factory tint that complies with the federal standard is exempt, with proof of compliance carried in the vehicle.
- Applying tint so that driving the vehicle breaks the rule is a Class A infraction, unless the work is done for someone who gives the installer a physician's or optometrist's statement.
