No, 35% window tint is not universally legal in Tennessee. State law mandates front-side windows allow ≥35% light transmittance, but local jurisdictions may impose stricter limits. Nashville’s 2024 ordinance caps front windows at 35%, while Memphis enforces 27%—creating a patchwork of compliance requirements. Non-compliant vehicles risk citations under Tennessee Code Annotated § 55-9-403.
Key Regulations for 35% Window Tint in Tennessee
- Front-side windows: Must transmit ≥35% visible light (VLT) unless local ordinances mandate higher thresholds. Nashville’s 2024 amendment aligns with state minimums, but Shelby County (Memphis) enforces 27% VLT.
- Rear windows: No state-mandated VLT minimum, but law enforcement may challenge tint deemed “excessively dark” under § 55-9-403’s “safety” provisions.
- Medical exemptions: Tennessee permits waivers for drivers with physician-certified conditions requiring reduced light transmittance, valid for up to 3 years per § 55-9-404.
Local enforcement varies; Knoxville and Chattanooga default to state minimums but may issue warnings for non-reflective tints below 20% VLT. The Tennessee Department of Safety and Homeland Security (TDOSHS) conducts random compliance checks, particularly in Davidson and Shelby Counties. Vehicles modified post-2026 must adhere to updated VLT standards pending legislative review.
