What is Tint Laws?

Tint laws are regulations that govern the darkness of window tints for vehicles. The laws are different from state to state. However, they are designed to ensure that motorists have enough visibility and emergency personnel can be able to see through vehicles in the event of an accident.

In the United States, window tint laws are typically determined by the percentage of Visible Light Transmission (VLT). The VLT represents the percentage of sunlight flowing through the window film. A higher percentage of VLT indicates that more light passes through the film, whereas a lower percentage of VLT indicates that less light gets through.

Legally, the VLT percentage for tinting windows differs from state to state. In certain states, different VLT percentages apply to different kinds of windows. For instance, the percentage of VLT for the windshield might be different from the percentage of VLT for side windows.

Tint Laws

It is generally accepted that the legally-required VLT percentage for windshields can be 70% or greater. This means that the glass must permit 70% of visible light to go through. The legally required VLT percentage for side windows is usually lower and can range between 25% and 50%. This means that side windows need to let 25 to 50% of the visible light pass through.

There are a few exemptions from the law regarding window tints. Some states, for instance, permit medical exemptions. This means that those who suffer from certain medical conditions, like sensitivity to light, might be permitted to wear a dark tint than is typically permitted.

If you’re considering getting your car tinted, it is essential to research the window tint laws of your state before doing this. You can locate the window tint law for your state by going to the state’s Department of Motor Vehicles (DMV) website.

  • To protect law enforcement officers and emergency personnel.
