Understanding Window Tint Measurements

Window tint darkness is measured by Visible Light Transmission (VLT) percentage. The higher the VLT percentage, the more light passes through the window. For example, a 70% VLT means 70% of visible light passes through the tint and glass combined.

Common VLT Requirements

Windshield: 70-100% VLT (AS1 line)
Front Side Windows: 30-70% VLT
Back Side Windows: 30-50% VLT
Rear Window: 30-50% VLT

Key Measurements

Net VLT: Combined tint and glass
Reflectivity: Mirror-like appearance
AS1 Line: Windshield tint boundary
Tolerance: Measurement margin

Common Window Tint Regulations

Medical Exemptions

Many states offer medical exemptions for darker tint. These typically require documentation from a licensed physician and state approval.

Certification Requirements

Some states require tint shops to be certified and tint installations to include certification stickers on the vehicle.

Enforcement & Penalties

Violations can result in fines, failed inspections, or requirements to remove non-compliant tint.

Important Considerations

•
Multi-State Travel: If you frequently travel between states, consider complying with the strictest applicable tint laws.
•
Professional Installation: Using certified installers helps ensure compliance and proper documentation.
•
Law Updates: Tint regulations can change. Regular verification of current laws is recommended.
•
Documentation: Keep any relevant certificates, medical exemptions, or legal documentation in your vehicle.
