The Legal BitYou will need to make sure you know the relevant laws regarding window tinting in your state. It is not really possible to give a definitive guide as the rules differ from state to state, but this is how it works. It is all about visible light transmission – or VLT.
VLT is a measurement of the amount of light that gets through a window. It is worked out by looking at a combination of the factory tint plus any tinting film you apply. The laws in your state will determine what level of tint you can apply to each window of your car.
Higher numbers mean more light can get in the window. For example:
- 70% VLT – This means 70 percent of light will get in the window so this is a relatively light tint.
- 5% VLT – Only 5 percent of light will get through the window in this example so this is quite a dark tint.
Let’s look at some state-by-state examples:
California Tint Law
- Windshield – A non-reflective tint is allowed in the top 4 inches of the windshield, but the rest must be left clear.
- Front Side Windows – 70 percent of light must come in through front side windows so the tint film used on cars in California has to be 70% VLT or lighter.
- Rear Side Windows – Any percentage of VLT can be applied so window tints can be as dark as you want them to be.
- Other Rules – The tinting films applied to both the front and side rear windows cannot be reflective and certain colors are not allowed, specifically red, amber and blue.
- Windshield – A non-reflective tint is allowed in the top 6 inches of the windshield but the rest must be left clear.
- Front Side Windows – Nothing can be applied to these windows.
- Rear Side Windows - Any percentage of VLT can be applied so window tints can be as dark as you want them to be.
- Other Rules – Any tinting films used must be non-reflective, but there are no restrictions on color.
