Regarding windows other than the windshield, Indiana law permits any legal tint with at least 30% light transmission applied to side windows and rear glass.

Windshield tinting regulations are more stringent. A legal tint of at least 30% transmitted light is allowed only on the uppermost part of the windshield, specifically above the AS-1 line. This line, typically located a few inches below the top of the windshield, marks the limit for permissible tint.

Exceptions to these rules exist for individuals with medical needs. It may be permitted if a physician or optometrist prescribes a darker tint for medical reasons. However, drivers must carry the doctor’s statement inside their vehicle, and this documentation must be updated annually.

Authorities emphasize the safety concerns associated with windshield tinting below the AS-1 line. Such tinting can significantly reduce visibility, particularly in low-light conditions, creating a hazardous situation for drivers. Imagine driving with sunglasses at night or in poor weather – extremely dark window tint can have a similar effect, making it difficult to see the road, other vehicles, pedestrians, and traffic signs.

Another critical safety issue is the impact of tinted windshields on eye contact. Motorcycle riders, pedestrians, bicyclists, and other drivers rely on eye contact with drivers for safety. Tinted windshields can prevent this crucial form of communication, making it difficult to gauge whether a driver has seen them and potentially increasing the risk of accidents. Drivers are urged to prioritize safety and ensure their window tinting complies with Indiana law.
