Is 50% Window Tint Legal in Tennessee After the 2026 Regulatory Updates?

No. Tennessee prohibits 50% window tint on front side windows and windshields, mandating 70% light transmittance for compliance. Violations risk fines up to $200 per offense under state traffic codes. Local jurisdictions like Nashville and Memphis enforce stricter ordinances, with 2026 revisions potentially increasing penalties for non-compliant vehicles.

Key Regulations for 50% Window Tint in Tennessee

  • Front Side Windows: Must allow ≥70% light transmittance; 50% tint is illegal.
  • Windshield: Non-reflective tint is permitted only above the AS-1 line; 50% tint violates this.
  • Rear Windows: Permitted if vehicle has outside mirrors; 50% tint is legal here but requires compliance labels.

Tennessee’s 2023 amendments to T.C.A. § 55-9-402 codify these standards, with enforcement delegated to local law enforcement and the Tennessee Department of Safety. Vehicles registered out-of-state must comply upon inspection or face registration holds. Aftermarket tint installations require certified documentation proving compliance with SAE J1203 standards. Failure to provide proof during traffic stops may result in citations.
