Knowing about the tricky window and windshield tinting laws is a must for those who want to use vehicle window tints. Before installing any tint, you must understand the legal window tint percentage for your state. This article breaks down these laws in detail. So, read on!
What Are Window Tint Percentages?

Tint percentages, simply stated, are the percentage of the visible light that a vehicle tint allows to pass through it. In other words, tint percentage defines the Visible Light Transmission (VLT) of the tint material. Window tints with a lower percentage will allow little light to pass through, making the windows dark.
For example, a 20% or 30% tint will allow less light than 50% and 70% tints to cross it. This is because the former will allow only 35% of the total light to pass through them. On the other hand, a 70% tint will let 70% of the visible light inside the vehicle, making it well-lit.
Understanding VLT (Visible Light Transmission)

Understanding VLT is crucial to understanding the science behind tint percentages. VLT determines the level of darkness inside your vehicles after tints are used. A higher VLT percentage means more light will be passed through the window tint film. On the contrary, lower VLT will make the tint dark, allowing little light to pass through.
Your chosen window tint percentage is an important factor that affects the following:
- Visibility: Dark tints with less VLT percentage will reduce significant glare. This will reduce visibility, making it harder to see at night.
- Privacy: Darker tints will also offer more privacy inside the vehicle. These tints won’t allow people from outside to see inside your car.
- Legal Compliance: For each state and region, there are well-defined laws about vehicle window tinting and how dark it can be. The tint you choose must adhere to your local tinting laws.
Different Window Tint Percentages Comparison

Here is a concise, yet insightful, comparison of different tint percentages in terms of what they offer:
Tint Percentages | Description | Used For |

5% (Limo Tint) | Very dark tint that allows little light inside | Limousines, VIP vehicles, privacy |
20% Tint | Common factory tint that is dark and offers privacy | Moderate privacy with great heat and light reduction |
30% Tint | Optimal tint choice for generic use. Offers good visibility while blocking significant light and heat. | Common public vehicles, stylish aesthetic appeal |
50% Tint | Lighter tint that works quite well for glare reduction | UV and heat reduction without hindering visibility |
70%+ Tint | Very light tint. Offers full visibility with little heat reduction | Glare and UV radiation blocking without reducing visibility |

- AS-1 Line – This is a point marked on vehicle windshields to indicate the screen area where tinting can be done.
- Reflectivity – This refers to how much light a window tint can reflect to reduce glare and heat.
Window Tint Types With Pros & Cons

- Dyed Tint – This is a budget-friendly tinting option for added privacy and glare reduction. The dye can fade with time and start offering limited glare and heat rejection.
- Ceramic Tint – Ceramic window tint is a premium tint that offers great heat and UV rejection. It is durable and lasts long. However, its very expensive.
