Vehicle window tinting has become a customary aspect of vehicle enhancement and serves a practical purpose too. It has gained popularity as a widely adopted car modification, being practically essential in certain states. A specialized polyester material, referred to as window tint, is used to treat contemporary car windows, safeguarding passengers from both UltraViolet (UV) and Infrared (IR) rays of the sun.

How Much Can You Darken Your Vehicle Windows?

Enthusiastic vehicle owners appreciate the advantages of window tinting, which include safeguarding against UV rays, mitigating glare, and maintaining privacy, besides adding an element of style to their vehicle's appearance. Currently, the trend leans towards "black," with a deep tint being a preferred choice for many. However, if you are considering a darker limo-style tint, it is essential to familiarize yourself with your state's regulations. Many states impose restrictions on the permissible degree of tint. Refer to the chart below outlining tint laws to determine the maximum darkness your windows can have.

Window films can be applied to a variety of glass surfaces. They are particularly appreciated for the enhanced aesthetic appeal they lend to vehicles while also reducing sun glare. Tinted windows not only block UV rays, considerably reducing the heat within but also protect materials like leather, steel, rubber, plastics, and aluminum. Passengers also benefit from the shield against potentially carcinogenic UV rays.

Understanding Window Tint Terminology

As you delve into the various laws and regulations governing car window tinting in different states, you'll encounter specific terminology. Understanding these terms will guide you in making informed choices for your vehicle. Keep in mind, when reading these laws, that tint percentages indicate the quantum of light permitted to pass through, otherwise known as Visible Light Transmission (VLT) percent. Windshield tinting laws determine the portion of the windshield that can be legally tinted or the extent of tint permissible on the entire windshield, contingent on the state's regulations.

VLT%: This stands for Visible Light Transmission. VLT% represents the volume of visible light permitted through either the film alone or both the film and window together. Lower VLT% translates into a darker tint, while a higher percentage denotes a lighter tint.

Front-side window tint %: The extent of tinting for the front-side windows must not surpass the VLT% stated in the chart. This percentage is relatively higher than that allowed for rear windows, allowing law enforcement officers to see inside the car.

Back-side window tint %: The extent of tinting for the back-side windows must not exceed the VLT% stated in the chart. The permissible limit will fluctuate depending on whether the vehicle is a car or an MPV (Multi-Purpose Vehicle).

Rear window tint %: This denotes the VLT% that's permissible for your rear window.

Windshield: The information pertains to the AS-1 line, considering complete windshield tinting isn't legally permissible in any state. The AS-1 line is 4-6 inches from the top of the windshield that can be tinted.

Reflectivity: Reflectivity of window tint is the quantum of light that the tinted film deflects away from the window. Lower reflectivity implies less light is either blocked or reflected off the window, aiding in mitigating glare and heat accumulation in the vehicle.

Why Do Some States Prohibit Window Tinting?

The law restricts window tinting in many states mainly for safety and security reasons. Although tinting comes with several benefits, it reduces the amount of light entering the car, potentially impairing the driver's visibility. This lack of clarity can lead to more accidents, particularly when the tint is extremely dark. From a law enforcement perspective, overly dark tinting prevents police and other agencies from seeing inside vehicles, hindering investigations and posing risks during traffic stops. Each state has distinct laws specifying the acceptable levels of tinting to balance between the benefits of tint and public safety.

Can You Be Stopped For Tinted Windows?

The short answer is, it depends. Each state has its unique laws governing window tinting. While many states have legalized some form of tinting, if your tint doesn't comply with those regulations, you might be stopped. In states where tinting is completely forbidden, any tinting attempt will likely attract law enforcement attention. It's crucial, therefore, to understand and adhere to your state's specific laws.

Is Limo Tint (Blacked Out Tint) Legal?
