The legal percentage of window tint you can use on your car varies significantly depending on your location. Each state (and sometimes even specific localities) has its own laws regarding Visible Light Transmission (VLT), which dictates how much light must be able to pass through the window after the tint is applied. Before tinting your car windows, understanding these regulations is crucial to avoid fines and legal issues.
Understanding VLT and Window Tint Laws
Visible Light Transmission (VLT) is the percentage of visible light that passes through a tinted window. A lower VLT percentage means a darker tint. For example, a 5% VLT tint allows only 5% of visible light to pass through, making it very dark. Conversely, a 70% VLT tint allows 70% of visible light to pass through, making it a much lighter tint.
State laws dictate the allowable VLT percentage for each window on your vehicle, typically specifying different restrictions for the windshield, front side windows, and rear windows. It’s important to note that even “untinted” glass has a slight tint, usually around 70-80% VLT. Therefore, any film applied will lower the overall VLT. Failing to comply with state regulations can result in hefty fines, mandatory tint removal, and even failure to pass vehicle inspections.
The Importance of Knowing Your State’s Laws
Researching your state’s specific window tint laws is the first and most vital step before getting your windows tinted. Many state DMV (Department of Motor Vehicles) websites offer detailed information, and reputable tinting shops are typically knowledgeable about local regulations. Ignoring these laws can lead to legal repercussions. Laws are subject to change, so ensure you have the most up-to-date information. Resources like the International Window Film Association (IWFA) can also be helpful in finding general information, but always verify with your local authorities.
How to Find Your State’s Window Tint Laws
Finding the specific regulations for your state is relatively straightforward:
- State DMV Websites: Most state Department of Motor Vehicles (DMV) or equivalent agencies have sections dedicated to vehicle equipment regulations, including window tint laws.
- Legal Databases: Websites that provide legal information, such as state legislature websites, often contain the full text of traffic laws and regulations.
- Professional Tinting Shops: Reputable tinting businesses are generally well-versed in local window tint laws and can provide guidance.
- Law Enforcement Agencies: Your local police department or sheriff’s office can also provide information on window tint regulations.
Factors Affecting Window Tint Legality
Several factors, beyond just the VLT percentage, can affect the legality of your window tint:
- Reflectivity: Some states regulate the reflectivity of the tint, which can be influenced by the type of film used. Reflectivity can impact visibility, especially at night.
- Color: Certain states prohibit specific tint colors, such as red or amber, as they can interfere with traffic signals.
- Certifications: Some states require the tint film to be certified and display a sticker indicating its compliance with local laws.
- Medical Exemptions: Many states offer medical exemptions for darker tints if a physician certifies a medical need, such as photosensitivity.
Window Tint FAQs: Addressing Your Concerns
Here are some commonly asked questions about car window tint legality:
FAQ 1: What is VLT and how does it relate to window tint?
VLT stands for Visible Light Transmission. It represents the percentage of visible light that can pass through a tinted window. A lower VLT percentage indicates a darker tint. For example, a 35% VLT tint allows 35% of visible light to pass through, blocking 65%. Understanding VLT is crucial for complying with state window tint laws.
FAQ 2: What are the general VLT limits for front side windows?
The VLT limits for front side windows vary widely by state. Some states allow as low as 35%, while others require 70% or higher. It’s essential to check your specific state’s regulations. Keep in mind that most factory glass already has a slight tint, so adding any film will further reduce the VLT.
FAQ 3: Can I use different tint percentages on different windows?
Yes, in many states, the allowable tint percentage differs for different windows. Rear side windows and the rear windshield often have less strict regulations compared to the front side windows and windshield. Always refer to your state’s specific laws to understand the permissible VLT for each window.
FAQ 4: What happens if my window tint is illegal?
If your window tint is found to be illegal, you could face fines, a requirement to remove the tint, and potential failure to pass vehicle inspections. In some cases, illegal tint can also lead to secondary offenses if it obstructs law enforcement visibility.
FAQ 5: Are there any medical exemptions for darker tints?
Yes, many states offer medical exemptions for darker window tints if a licensed physician certifies a medical need, such as photosensitivity or certain skin conditions. The exemption typically requires documentation carried in the vehicle.
FAQ 6: How can I measure the VLT of my window tint?
Professional tint shops often have VLT meters that can accurately measure the light transmission of your window tint. You can also purchase aftermarket VLT meters, but their accuracy may vary. Using a professional service is recommended for ensuring compliance.
FAQ 7: Does window tint void my car warranty?
Generally, installing window tint will not void your entire car warranty. However, if the tint installation directly causes damage to the window or other car components, those specific damages might not be covered under warranty. It’s always best to check with your car manufacturer or dealership for clarification.
FAQ 8: What is the legal limit for windshield tint?
Windshield tint laws are typically very strict. Most states prohibit tinting below the AS-1 line (a marked line on the windshield) or allow only a non-reflective strip at the top of the windshield. Some states completely prohibit any tinting on the windshield beyond this strip.
FAQ 9: Does the type of window film affect its legality?
Yes, the type of window film can affect its legality. Some states regulate the reflectivity of the film, while others prohibit certain colors. Using metallic or highly reflective films can be problematic in some jurisdictions. Consult your state’s regulations and a professional installer for guidance.
FAQ 10: How often do window tint laws change?
Window tint laws are subject to change, although significant overhauls are relatively infrequent. It is advisable to check for updates annually, especially before getting new tint installed. Stay informed by monitoring state legislative websites or consulting with reputable tinting shops.
FAQ 11: What are the benefits of using legal window tint?
Legal window tint offers several benefits, including reduced glare, decreased interior heat, protection from UV rays, and enhanced privacy, without violating the law. It can also help protect your car’s interior from fading.
FAQ 12: Where can I find a reputable window tinting installer?
Look for installers who are certified by organizations like the International Window Film Association (IWFA) or have positive reviews and a strong reputation in your local area. A reputable installer will be knowledgeable about local laws and use high-quality films. They should also offer a warranty on their work.
