Where Are Tinted Windows Illegal? State By State (2025)

Understanding Visible Light Transmission (VLT)

To understand window tint regulations, it’s important to first get an idea of how the degree of window tint is quantified. This percentage is known as the visible light transmission (VLT), and it’s often expressed as VLT%. Because a smaller VLT% means less sunlight is let in, smaller values correspond to darker windows.

For instance, a 28% tint lets in 28% of visible light. Windows with a 28% tint are darker than those with a 70% tint because the latter windows let in 70% of visible light.

Legal Tint Limits for Different Vehicle Windows

Window tinting laws are significantly more complex than many people realize. For example, the laws in specific states may permit different levels of tint for different windows:

• Front-seat windows are generally required to be much less tinted
• Backseat windows can usually be slightly more tinted
• Rear windows are often allowed the most tint

Windshield tinting laws are a little different than regulations for other windows in the vehicle. In most states, the law stipulates how much of the windshield may be tinted. Commonly, windshields may not be tinted below the windshield’s AS-1 line. This line is usually six inches below the top of the windshield.

State-by-State Window Tint Regulations

Many states have specific designations regarding the reflectivity, color, portion of the windshield affected, and placement of tinted windows on vehicles.

Medical Exemptions for Window Tinting

Most states allow drivers with certain medical conditions to apply for a window tint exemption. If you have a medical condition that causes severe sensitivity to light, you may be able to qualify. These are some examples:

• Lupus
• Solar urticaria
• Albinism
• Erythropoietic protoporphyria
• Xeroderma pigmentosum

Each state has its own exemption process, but generally, you must at least have a doctor’s note to verify the necessity of darker windows on your vehicle.

Penalties for Illegal Window Tinting

Illegal window tint may not be as serious as a DUI or other major traffic offense, but it still comes with consequences. Often, drivers caught with too-dark windows will be issued a ticket and a fine.

Some jurisdictions will instead give you a “fix-it ticket.” This ticket requires you to resolve the issue and provide proof you’ve done so. In many states, illegal window tint is treated as an equipment violation, which can lead to escalating penalties if ignored.

If you receive a ticket, you may also find that your average car insurance cost per month increases.

Tips for Complying With Tint Laws

To avoid accidentally violating tint laws, follow these helpful tips:

• Check your state laws before getting windows tinted or when moving to another state
• Always have your tint done by a professional
• Be cautious when purchasing a vehicle with existing tinting on the windows, especially if you’re buying a car from another state
• If you think your existing tint may be illegal, ask a professional to check

Visiting a professional, licensed installer is critical .These installers use highly accurate tools to verify that the tint falls within the legal allowances.

Impact of Tint Laws on Vehicle Inspections

If your state has required vehicle inspections, it’s essential to pay attention to tint laws. A car with too-dark tint will likely fail inspection, making it impossible to renew your registration until you fix the issue. Without registration, you may not be able to drive the car legally, obtain insurance on it, or sell the car to another party.
