Thinking about tinting your car in Indiana, or not sure if your current tint is legal? This page explains the main Indiana window tint laws in clear, simple language so you know what you can safely use.
Quick Rules at a Glance
- Applies to everyone: Indiana’s tint law applies to any motor vehicle driven in the state, no matter where it is registered.
- Windshield: Only non-reflective tint is allowed above the manufacturer’s AS-1 line at the top of the glass. No dark film is allowed below that line under normal rules.
- Front side windows (driver & passenger): Must allow at least 30% of visible light through (about 30% VLT or lighter). Tint may be no more than about 25% reflective.
- Back side windows (behind the driver) – passenger cars: Must also allow at least 30% of light in.
- Rear window (back glass) – passenger cars: Must allow at least 30% of light in.
- SUVs, vans, pickups (multi-purpose vehicles):
- Front side windows: Same 30% VLT rule as cars.
- Rear side & rear windows: Many guides interpret Indiana law as allowing very dark tint on these windows, as long as you can still see occupants and the film is not more than about 25% reflective.
- Reflectivity: Tinted side and rear windows may be no more than about 25% reflective (no mirror or chrome look).
- Colors: No specific colors are banned in the text of the law, but mirror-like and strongly colored films can still draw attention and cause problems.
- Medical exemption: People who must be shielded from the sun for health reasons can qualify for a medical tint exemption with a doctor’s or optometrist’s letter that must be carried in the vehicle and renewed every year.
- Enforcement: A vehicle may be stopped to check tint, but officers may not search or detain you only because of tint. Violations are handled as infractions and usually mean a small fine and an order to fix the tint.
In simple terms: keep side and rear windows at about 30% VLT or lighter, use only a strip above the AS-1 line on the windshield, and avoid mirror-like films.
What Is VLT?
Indiana, like most states, uses Visible Light Transmission (VLT) to measure how dark tint is.
- VLT is the percentage of visible light that passes through the glass and tint film together.
- Higher VLT (for example 70%) means lighter tint.
- Lower VLT (for example 20%) means darker tint.
When you see “30% tint,” it means the glass and tint combined let about 30% of light through and block about 70%.
Indiana law uses 30% as the key legal cutoff for most windows.
Windshield Tint Rules in Indiana
The windshield has the tightest limits because it is your main field of view.
- You may not drive a vehicle with a windshield covered or treated in a way that keeps people inside from being easily recognized from outside.
- Any legal tint or sunscreening material on the windshield:
- Must be non-reflective, and
- May be applied only to the uppermost part of the glass, down to the manufacturer’s AS-1 line (marked on the windshield).
- No dark film is allowed below the AS-1 line under the standard rules.
Think of it as a thin strip along the top of the windshield, with the rest kept clear.
Tint Darkness for Passenger Cars (Sedans, Coupes, Hatchbacks)
For regular passenger cars, Indiana law is fairly simple: the same basic numbers apply to all the main windows.
Front Side Windows
- Front side windows must allow at least 30% of visible light through.
- Tint may not be more than about 25% reflective.
- Shops usually install film labeled around 30–35% VLT on the front doors to stay safely above the legal minimum once you combine film and glass.
- Very dark film like 15% or 5% “limo” on the front doors is almost always too dark for Indiana.
Rear Side Windows & Rear Window
- On passenger cars, the rear side windows and rear window should also allow at least 30% of light in.
- They are held to the same “no more than about 25% reflective” expectation.
- Even on the back glass, officers should still be able to easily recognize occupants from outside the vehicle.
A very common legal setup for Indiana passenger cars is 30–35% tint on all side windows and the rear window, with only a small non-reflective strip at the top of the windshield.
Tint Darkness for SUVs, Vans & Pickups (Multi-Purpose Vehicles)
Indiana’s statute does not spell out a separate number for larger vehicles, but most legal guides treat them with a bit more flexibility in the rear.
Front Side Windows
- Front side windows on SUVs, vans, and pickups must follow the same rule as cars:
at least 30% VLT, and no more than about 25% reflective. - Dark 15% or 5% tint on the front doors is still too dark even on a big truck or SUV.
Rear Side Windows & Rear Window
- Many summaries interpret Indiana law as allowing very dark tint on the rear side windows and rear window of multi-purpose vehicles.
- Even so, the film should not be excessively reflective, and occupants should still be recognizable from outside.
- If your rear window is tinted so heavily that you cannot see straight back clearly, make sure your vehicle has good side mirrors on both sides.
In practice, you will often see SUVs and vans in Indiana with 30% on the front doors and much darker factory or film tint on the back half of the vehicle.
Reflectivity & Color Rules
Indiana limits how shiny your tint can be, not just how dark it is.
- Reflectivity: Side and rear windows should not be more than about 25% reflective.
- No mirror look: Chrome-like, mirror-style films that throw back a lot of light can be treated as unlawful.
- Colors: The law does not list specific banned colors, but bright or odd colors and anything that looks like emergency lighting can still get you pulled over.
- Most people choose neutral gray, charcoal, or black films without strong color or shine.
Medical Tint Exemptions
Indiana does allow special tint for people who must avoid direct sunlight for medical reasons.
- The tint law does not apply to:
- A vehicle owned by a person who must be shielded from the direct rays of the sun for medical reasons, or
- A vehicle in which such a person is a habitual passenger.
- The medical need must be certified by a physician or optometrist licensed in Indiana.
- The doctor’s or optometrist’s certificate:
- Must be carried in the vehicle whenever it is driven, and
- Must be renewed every year.
- With a valid certificate, darker tint and different setups (such as light tint on the full windshield) can be allowed, as long as reflectivity limits are still respected.
Without that certificate in the car, your tint will be judged under the regular 30% rules, no matter what your health situation is.
Penalties & Enforcement
Indiana treats illegal tint as an equipment violation, not a criminal offense.
- A vehicle may be stopped briefly just to check tint and see if it meets the law.
- Officers may not search or detain you solely because of a tint violation, beyond what is needed to issue a ticket.
- Tint violations are usually charged as an infraction (often Class A or Class C, depending on details).
- Typical fines are often in the tens of dollars range (around the size of a small traffic ticket), but amounts can vary by court and county.
- Repeated violations or ignoring orders to fix obvious illegal tint can lead to higher fines and more hassle.
Is Your Tint Probably Legal in Indiana?
Use this quick check as a rough guide:
- Windshield:
- Only a non-reflective strip above the AS-1 line?
- No dark film across the main part of the windshield?
- Front side windows:
- Film labeled around 30–35% VLT? → Usually okay.
- Film labeled 20% or 5%? → Almost certainly too dark.
- Rear side windows & rear window – passenger car:
- Film around 30% VLT or lighter? → Typically legal.
- Rear side windows & rear window – SUV/van:
- Very dark rear tint is common and often allowed, especially with good side mirrors.
- Reflectivity & look:
- No mirror-like chrome finish?
- Neutral charcoal/gray rather than bright or odd colors?
- Medical tint?
- If you rely on a medical exemption, do you have a current doctor certificate in the vehicle?
If your tint is close to the limit, the only sure way to know is to have it checked with a tint meter by a shop, inspection station, or law enforcement.
Important Legal Note
This page is a plain-language summary of Indiana Code 9-19-19-4 and related guidance.
It is not formal legal advice and may not cover every special case or local policy.
For a serious ticket, court case, or very custom tint setup, you should read the current statute text and speak with an Indiana attorney or local law enforcement.
Summary
To stay comfortable and legal on Indiana roads:
- Keep front side windows at about 30% VLT or lighter.
- On passenger cars, keep the rear side windows and rear window at roughly 30%+ VLT.
- Limit windshield tint to a non-reflective strip above the AS-1 line.
- Avoid mirror-like, highly reflective films.
- If you need darker tint for health reasons, use the medical exemption process and keep your doctor’s certificate in the car.
Follow these guidelines and you can enjoy cooler, more private windows without constantly worrying about Indiana tint tickets.
