Is Windshield Tint Legal? Complete Guide to Window Tint Laws 2026

The Short Answer

In most US states, tinting the entire windshield is illegal. However, most states allow a non-reflective tint strip at the top of the windshield (above the AS-1 line, typically the top 4-6 inches). Side and rear window tint laws vary significantly by state.

Understanding VLT (Visible Light Transmission)

Tint darkness is measured as VLT percentage — the amount of visible light that passes through the glass.

• Factory clear glass: 70-80% VLT (already slightly tinted)
• Light tint: 50% VLT (subtle darkening)
• Medium tint: 35% VLT (most common legal limit for front windows)
• Dark tint: 20% VLT (common for rear windows)
• Limo tint: 5% VLT (very dark, illegal on front windows everywhere)

State-by-State Front Side Window Limits (2026)

• California, New York, Pennsylvania, Texas: 70% VLT (essentially no aftermarket tint)
• Florida: 28% VLT
• Arizona, Nevada, New Mexico: 33% VLT
• Colorado: 27% VLT
• Illinois, Indiana: 30% VLT on front sides, any darkness on rear

Clear UV-Blocking Film: Legal Everywhere

Clear ceramic film (70%+ VLT) blocks 99% of UV rays and 50%+ of infrared heat without changing the appearance of your windows. This is legal in every state and provides the most important benefit of tint (UV and heat protection) without legal risk. Cost: $200-400 for front two windows.

Medical Exemptions

Many states offer medical exemptions for drivers with photosensitivity conditions (lupus, melanoma, certain medications). You need a doctor's letter and state DMV approval. The exemption allows darker tint than normally permitted, but still requires some minimum VLT (typically 20-35%).

Consequences of Illegal Tint

Fines ($50-500 depending on state), required removal, and possible vehicle inspection failure. In some states, illegal tint can void your insurance if an accident is attributed to reduced visibility.
