Indiana window tint laws require at least 30% VLT on regulated windows. Window film may not exceed 25% solar reflectance under state law. Most violations are a Class C infraction with judgments up to $500. Coverage here includes windshield rules penalties enforcement and medical exemptions. These rules come from the Indiana Code and Indiana General Assembly.
Tint Terms Defined
Window tint law relies on a few core terms. VLT means visible light transmittance through the glass and film. A higher VLT number means lighter tint and more visible light. So 30% VLT allows more light than a darker film. Solar reflectance measures how mirror like the film appears.
The statute calls window film sunscreening material. The AS 1 line sits near the top of the windshield. Tint above that line stays legal on the windshield. A Class C infraction is a minor civil violation. A Class A infraction is a more serious civil violation.
What Indiana Window Tint Laws Cover
Indiana sets a 30% VLT minimum on the regulated windows. This applies to the windshield front side wing and front door window. It also applies to the rear back window. Each named window must allow at least 30% light through. These limits come from Indiana Code Section 9-19-19-4.
The same statute caps film at 25% solar reflectance. Reflectance is measured on the nonfilm side of the glass. Mirrored or metallic film that exceeds 25% is not allowed. The 25% reflectance cap differs from the 30% VLT rule. Indiana also places no ban on tint colors.
Indiana keeps one VLT number across front and rear windows. The front side wing falls under the 30% VLT rule. The front door window falls under the same 30% rule. The rear back window also requires 30% VLT. This uniform approach is simpler than many other states.
Windshield Tint Rules Explained
Windshield tint must stay above the AS 1 line. Only non reflective tint is allowed on the windshield. The statute limits this tint to the uppermost part. It may extend no further than the AS 1 line. You can read the rule on Justia for Indiana Code Section 9-19-19-4.
Some windshields show no visible AS 1 line. In that case tint stays within 5 inches from the top. The AS 1 line carries small markings on the glass. It usually sits near the side edges of the windshield. Only non reflective film is allowed in that top band.
Who The Law Covers
The tint rules apply to people who drive on public roads. Indiana applies the 30% VLT rule to all four named windows. The statute text lists no darker option for the rear window. It does not carve out a separate rule for SUVs. Vans fall under the same 30% VLT standard.
Factory glazing follows a federal standard called FMVSS 205. That standard appears at 49 CFR Section 571.205. Indiana Code Section 9-19-19-4 defers to that federal rule. Manufacturer tint that meets FMVSS 205 stays compliant. Drivers must carry proof of that compliance in the vehicle.
Documents Drivers Must Carry
Indiana ties some tint allowances to paperwork in the car. Proof of FMVSS 205 compliance must stay in the vehicle. That proof can come from the manufacturer supplier or installer. Proof must be available during a compliance stop. Missing proof can expose a driver to a tint citation.
A medical exemption also depends on carried documentation. The driver must keep the certification inside the vehicle. A physician or optometrist licensed in Indiana must attest the condition. The certificate must be renewed every year. Without current paperwork the standard 30% VLT limit applies.
Tint Colors And Stickers
Indiana places no ban on tint colors. Drivers may use red amber or other colored film. Color choice does not change the 30% VLT minimum. Colored film still must meet the 25% reflectance cap. Banned colors are not part of Indiana tint law.
Indiana requires no sticker to mark legal tint. Other states sometimes require a compliance sticker. Indiana film makers must certify tint sold in state. Reputable installers carry only certified compliant film. Buyers can confirm certification with the installer.
Medical Exemption Rules
Indiana allows darker tint for documented medical needs. The exemption covers a driver shielded from direct sun rays. It also covers a habitual passenger with that medical need. The condition must be attested by a licensed physician or optometrist. The certificate must be renewed annually under Indiana Code Section 9-19-19-4.
The exemption only covers the darkness the clinician justifies. It is not automatic and it is not permanent. Installers may apply darker film when a valid statement exists. The film must match the authorized darkness. A driver may consult a licensed attorney about exemption questions.
Penalties For Illegal Tint
Most tint violations are a Class C infraction in Indiana. Indiana Code Section 9-19-19-7 sets that general classification. A Class C infraction carries a judgment up to $500. That ceiling comes from Indiana Code Section 34-28-5-4. Many drivers pay less than the $500 ceiling.
Indiana reduces required amounts for many moving violations. An early admission can lower what a driver pays. Court costs still apply on top of any judgment. Repeat violations within five years can raise the amount. The full schedule sits in Indiana Code Section 34-28-5-4.
A separate offense carries a heavier penalty. Indiana Code Section 9-19-19-8 covers tint that hides occupants. Tinting so occupants are not easily identified is a Class A infraction. A Class A infraction carries a judgment up to $10000. This offense targets hiding occupants from outside view.
Stops And Enforcement Limits
Police may stop a vehicle to check tint compliance. Indiana Code Section 9-19-19-4 subsection f allows that stop. Officers often use a tint meter to measure VLT. The meter reads how much light passes through the window. A reading under 30% can support a violation.
The same subsection limits what officers may do next. A tint violation alone does not justify a search. It does not justify detaining the driver or passengers. The vehicle contents may not be searched for tint alone. You can review the statute on the Indiana General Assembly site.
Common Tint Law Misconceptions
Some sources claim SUVs get unlimited rear window darkness. The current statute text does not support that claim. It lists the rear back window under the 30% VLT rule. Vans and SUVs follow the same named window limits. Readers can check darker rear claims against the statute.
Another mistake mixes up reflectance and light transmittance. The 25% figure is a reflectance cap not a VLT rule. The 30% figure is the visible light minimum. Some pages also quote a single flat fine. Indiana instead uses Class C and Class A infractions.
When Indiana Tint Laws Change
Laws and enforcement may change over time. Check official state sources for the latest rules. The most recent chapter amendment was Public Law 164-2018. No newer change to the 30% VLT limit was found. The 2025 Indiana Code reflects the current text.
Public Law 12-2003 added the Class A tint offense. Public Law 164-2018 later amended that same section. The offense now references Section 9-19-19-4 subsection e. Earlier versions pointed to a different subsection. Checking the current code avoids relying on outdated text.
Indiana window tint laws sit in Indiana Code Section 9-19-19-4. Penalty rules sit in Section 9-19-19-7 and Section 9-19-19-8. Judgment amounts come from Section 34-28-5-4. Readers comparing nearby states can review Iowa window tint laws next. Verifying current rules against official sources keeps tint choices compliant.
