Understanding Window Tint Percentages

What is VLT?

VLT stands for Visible Light Transmission. It measures the percentage of light that passes through your window tint film. A lower VLT percentage means darker tint — 5% VLT is a very dark "limo tint" while 70% is nearly clear.

Why Do Tint Laws Vary?

Each state sets its own window tint regulations. Laws typically differ between front side windows (stricter) and rear windows (more lenient). SUVs and trucks may have different limits than sedans in some states.

Medical Exemptions

Most states offer medical exemptions for drivers with conditions like lupus, photosensitivity, or melanoma. A physician's certificate is typically required and must be kept in the vehicle.

Tint-Friendly States

States like Michigan, Texas, and Arizona allow any darkness on rear windows, making them popular with tint enthusiasts.

Strictest

Heavily Regulated States

States like New York, Pennsylvania, and Rhode Island require 70% VLT on all windows — essentially no aftermarket tint on front windows.
