1. Visible Light Transmittance (VLT): VLT refers to the amount of light that can pass through the tinted window. The lower the VLT percentage, the darker the tint will be. Many states set a minimum VLT percentage for both front and rear windows. For example, in California, the minimum VLT is 70% for front side windows and 20% for rear side windows and the rear windshield.
2. Reflectivity: Reflectivity refers to the amount of light that is reflected off the tinted window. Some states have restrictions on how reflective window tint can be. High reflectivity can cause glare and visibility issues for other drivers.
The darkness level of permissible car window tint varies by state and may be subject to change. It's important to check with your local laws or the Department of Motor Vehicles (DMV) in your state to ensure compliance. Violating window tint darkness regulations may result in fines or even removal of the tint.
Here are a few examples of window tint darkness laws in different states:
1. California: Front side windows must allow at least 70% VLT, and rear windows (including the rear windshield) must allow at least 20% VLT.
2. Florida: Front side windows must allow at least 28% VLT, and rear windows (including the rear windshield) must allow at least 15% VLT.
3. Illinois: Front side windows must allow at least 35% VLT, and rear windows (excluding the rear windshield) must allow at least 20% VLT. The rear windshield must allow at least 35% VLT.
4. New York: Front side windows must allow at least 70% VLT, and rear side windows (excluding the rear windshield) must allow at least 35% VLT. The rear windshield must allow at least 70% VLT.
Remember that these are general examples and the specific regulations may differ in each state. Always consult official sources or your local DMV for the most up-to-date and accurate information on window tint darkness laws.
