Is 35% Window Tint Legal in Indiana After the 2026 Law Changes?

No. Indiana prohibits window tint darker than 33% light transmittance on front side windows, making 35% illegal. The state’s 2026 enforcement updates tighten compliance checks, with local law enforcement (e.g., Indiana State Police) prioritizing windshield and front window violations.


Key Regulations for 35% Window Tint in Indiana

  • Front Side Windows: Must allow ≥33% light transmittance; 35% fails this threshold. Violations incur Class C infractions (IC 9-19-1-1).
  • Windshield: Non-reflective tint is permitted only above the AS-1 line (top 4 inches). Any darker application violates IC 9-19-1-3.
  • Medical Exemptions: Require certification from an Indiana-licensed physician, submitted to the BMV. Exemptions do not apply to windshields.

Local ordinances (e.g., Indianapolis/Marion County) may impose stricter rules, including rear window restrictions. The BMV’s 2026 compliance directive mandates sticker verification during inspections, aligning with federal DOT standards. Non-compliant vehicles face fines up to $250 and mandatory tint removal.
