Window Tint Argyle by Autopro DFW: Unveiling the Benefits of Tinted Brilliance


Tinted windows are a popular modification among car owners, offering both aesthetic appeal and functional benefits such as reduced glare and enhanced privacy. However, the legality of windshield tint and front window tints varies significantly by country and state, creating a complex landscape for drivers to navigate. This blog aims to clarify whether windshield tinting, including the two front windows, is legal and what you need to know to stay compliant with local laws.

Understanding Windshield and Front Window Tinting

Window tinting involves applying a thin film to the car’s windows to darken them. This modification is not merely about looks; it provides several advantages, such as reducing heat and UV radiation inside the car, which can protect the interior and improve comfort for passengers. Despite these benefits, the degree of tint allowed, especially on windshields and front windows, is heavily regulated to ensure driver visibility and road safety.

The primary reason behind these regulations is to prevent accidents caused by impaired vision. Legislation on window tints aims to balance the benefits of reduced glare and heat with the need for clear visibility. These laws dictate how much Visible Light Transmission (VLT) a window tint must allow, with variations depending on the specific requirements of each state or country.

Key Points About Window Tinting Laws

Understanding Tint Darkness

What is VLT (Visible Light Transmission)?

Visible Light Transmission (VLT) is a key metric used to determine the darkness of window tints. It measures the percentage of visible light that passes through the window film and the glass. A lower VLT percentage indicates a darker tint, as less light can pass through. For example, a tint with a 35% VLT allows 35% of visible light to penetrate, while blocking the remaining 65%.

Legal Limits for Tint Darkness in Different States

Each state in the U.S. has specific laws regulating the allowable VLT for vehicle windows. These laws are designed to ensure that drivers maintain adequate visibility to safely operate their vehicles.Drivers must familiarize themselves with their state’s specific regulations to avoid penalties and ensure safe driving conditions.

Reflection Rules for Window Tints

What You Need to Know About Tint Reflectivity

Reflective window tints contain metallic elements that help reflect light, reducing heat and glare inside the vehicle. However, there are restrictions on how reflective these tints can be, as excessively reflective tints can impair visibility and create glare for other drivers.

Why Reflective Tints Are Restricted

Reflective tints can cause significant safety hazards by creating blinding glare for both the vehicle’s driver and other motorists. This is why many states impose limits on the reflectivity of window tints.

Color Choices for Tinted Windows

Allowed and Prohibited Colors

While most people opt for standard black or gray tints, some window tint films come in various colors. However, certain colors are prohibited due to safety concerns. For instance, red, yellow, and amber tints are typically banned because they can be distracting and may impair visibility.

Aesthetic and Functional Aspects of Tint Colors

Choosing the right color for window tints is not just about aesthetics; it also affects the vehicle’s functionality. Darker shades offer better privacy and UV protection, while lighter tints might be preferred for a more subtle appearance. It’s important to select a tint color that complies with local laws while meeting your personal preferences and needs.

Importance of Manufacturer Certificates

Why You Need a Certificate for Your Tint

Many states require a certificate from the tint manufacturer stating that the tint film complies with state laws. This certificate ensures that the tint meets the specific VLT and reflectivity standards set by the state.

How to Obtain and Display Certificates

To obtain a manufacturer certificate, you typically need to purchase your tint film from a reputable dealer who provides these documents. Once you have the certificate, it should be kept in the vehicle and presented to law enforcement if requested. Some states also require a sticker indicating compliance to be placed on the tinted windows.

Medical Exemptions for Window Tinting

Who Qualifies for Medical Exemptions?

Certain medical conditions, such as lupus, albinism, or severe photosensitivity, may qualify individuals for exemptions from standard window tint laws. These exemptions allow for darker tints to protect the individual from harmful UV rays.

How to Apply for a Medical Exemption

To apply for a medical exemption, you typically need a physician’s statement detailing the medical necessity for darker tints. This statement, along with a completed application form, must be submitted to the relevant state department (such as the Department of Motor Vehicles). Once approved, the exemption certificate should be carried in the vehicle at all times to avoid legal issues during traffic stops.

Understanding VLT and Tinting Regulations

Windshield Tinting Laws Explained: 

General Rules for Windshield Tints

Windshield tinting laws primarily focus on safety and visibility. Generally, the entire windshield must remain clear to ensure an unobstructed view for the driver and to allow law enforcement to see inside the vehicle. In most states, the use of a tinted film on the main area of the windshield is prohibited. However, certain transparent films that block UV rays without reducing visibility might be allowed.

Specific Regulations for Top Strips and Full Windshield Tints

Many states allow a tinted strip along the top of the windshield, often referred to as an “eyebrow” tint. The allowable width of this strip varies by state, typically ranging from 4 to 6 inches, or it may be dictated by the AS-1 line marked on most windshields.
