What Does VLT Mean?
VLT stands for Visible Light Transmission. It measures the percentage of light that passes through your window tint film. Each state sets its own legal VLT limits.
A higher VLT means more light passes through (lighter tint). A lower VLT means less light passes through (darker tint).
Example: A 70% VLT tint allows 70% of light through (very light), while a 5% VLT tint only allows 5% of light through (very dark — often called “limo tint”).
Reflectivity & Restrictions
Reflectivity: Front and back side windows must not be more than 35% reflective (no more reflective than standard glass)
- Red, amber, and blue tint colors are not permitted
- Dual side mirrors required if rear window is tinted
- Aftermarket tint on front side windows must meet the 70% VLT requirement combined with factory glass
Sticker Requirements
Film manufacturer must certify the film, and the certification label must be visible
Penalties
First offense: "fix-it" ticket (correction required). If not corrected, fines of $25 for first offense, $197+ for subsequent offenses.
