Is 15% Window Tint Legal in Texas After the 2026 Regulatory Updates?

Yes, 15% window tint is legal in Texas for rear windows and back side windows, provided it meets state reflectivity and darkness standards. Front side windows must allow over 25% light transmission. Local jurisdictions like Harris County may impose stricter rules; 2026 compliance shifts could tighten reflectivity limits to 20%.

Key Regulations for 15% Window Tint in Texas

  • Front Side Windows: Must transmit more than 25% of light (i.e., darker than 25% VLT is illegal). Texas Transportation Code § 547.613 enforces this.
  • Rear and Back Side Windows: 15% VLT is permissible, but non-reflective tint is required unless the vehicle has side mirrors on both sides (Texas Admin. Code § 217.34).
  • Reflectivity Limits: Tint must not reflect more than 25% of light (measured per ASTM D3334). Exceeding this triggers citations under local ordinances.

Enforcement Context: The Texas Department of Public Safety (DPS) and municipal police (e.g., Dallas PD) conduct roadside checks. Vehicles with aftermarket tint failing front-side compliance face fines up to $200 per violation. The 2026 Texas Rulemaking Agenda (Item 4-12) proposes stricter reflectivity testing protocols, aligning with federal NHTSA guidelines.

Exceptions: Medical exemptions exist under Texas DPS Form VTR-61 (e.g., for conditions like lupus). Documentation must be carried in the vehicle. Dealers installing non-compliant tint risk liability under Texas Occupations Code § 1702.
