Tinted windows offer privacy, reduce glare, and keep vehicles cooler. However, Indiana law strictly regulates the darkness and reflectivity of automotive window tint. Violating these rules can result in fines, vehicle inspection orders, and even impact insurance claims after an accident. Knowing the requirements before applying tint helps you stay legal and safe.
Visible Light Transmission (VLT) Basics
Window tint limits are generally measured using visible light transmission (VLT), which is the percentage of light that passes through the window and film combined. Lower VLT means a darker tint. Indiana’s rules vary by vehicle type, window, and reflectivity.
For passenger vehicles such as sedans, coupes, and station wagons:
- Windshield: Only non‑reflective tint is allowed above the manufacturer’s AS‑1 line (usually the top five inches of the windshield). The area below this line must remain untinted.
- Front side windows: Must allow more than 30% of light through. This requirement helps drivers see pedestrians, cyclists, and law enforcement officers clearly.
- Back side windows: Must also allow more than 30% of light through. A darker tint may attract police attention and lead to fines.
- Rear window: Must allow more than 30% of light through.
Multi‑purpose vehicles such as SUVs, minivans, and trucks may have slightly different rules:
- Windshield: Non‑reflective tint above the AS‑1 line only.
- Front side windows: Must allow more than 30% light transmission, similar to sedans.
- Back side windows and rear window: May be tinted to any darkness, allowing for privacy for passengers and cargo.
Some drivers of these types of vehicles may opt for a darker tint on the back side and rear windows, but maintaining visibility remains crucial for safety. It’s also best to consult with the proper authorities if you have questions or concerns about your vehicle’s compliance with Indiana’s window tint laws.
Reflectivity and Colors
Indiana also limits how shiny tint can be. Front and rear side windows cannot reflect more than 25% of light, preventing mirror‑like appearances that can blind other drivers.
While Indiana does not explicitly prohibit specific tint colors, hues such as red, amber, or yellow can attract law enforcement scrutiny because they impair visibility. It may be best to stick with neutral tones, such as charcoal or gray.
Medical Exemptions
Drivers with certain medical conditions may need a darker tint to protect their skin or eyes. Indiana law allows medical exemptions if a doctor certifies that special tint is necessary. The certification must be carried in the vehicle and renewed annually. Without an exemption, police may ticket vehicles with excessively dark tint even if the driver has a legitimate medical reason.
Protecting Your Rights After a Violation
If you receive a ticket for illegal tint, you have options. You can remove the tint and show proof of compliance to reduce or dismiss the fine. If you believe the citation was issued in error, you may contest it in court.
Keep in mind that judges often side with law enforcement, so strong evidence (such as a VLT reading from a certified shop) is essential. If illegal tint contributed to a collision and you face liability claims, consult an attorney who understands Indiana’s negligence laws and insurance regulations.
