Every state also has separate rules for rear windows, the windshield strip, reflectivity and tint color. The number on a shop's tint film box is not automatically legal in your state. A 35 percent ceramic film is legal in most of the country but would get a car pulled over in California or New York, where the front window minimum is 70 percent. ## Key facts - Front side window VLT minimums range from **20 percent** (New Mexico) to **70 percent** (California, New York, Pennsylvania, Delaware, Rhode Island, New Jersey, New Hampshire) - **25 percent** is the most common front window minimum, used by Texas, Arkansas, Louisiana and Oklahoma - Most states allow a **non-reflective tint strip** on the top 4 to 6 inches of the windshield, above the AS-1 line - Rear side and rear windows can usually be darker than front windows, often with **no VLT minimum** once dual side mirrors are installed - Nearly every state **bans red, amber and mirrored or metallic reflective tint**, regardless of VLT percentage - Most states offer a **medical exemption** for darker front tint with a signed physician's letter on file ## What VLT means on a statute VLT, visible light transmission, is the percentage of light that passes through the glass and film combined, not the film alone. A car's factory glass already blocks some light, so a "35 percent" film on factory glass often tests a few points darker than 35 percent VLT overall. States write their laws around the combined reading, which is also how a police VLT meter checks compliance. Lower VLT numbers mean darker glass. A 70 percent VLT law is strict because it only allows a light tint; a 20 percent VLT law is lenient because it allows a much darker film. ## How states compare, strict to lenient This is a sample across the range. Every state also sets separate rules for rear windows, reflectivity and color that do not show up in a front-window number alone, so check your specific state before booking. The full chart for all 50 states, updated for 2026 limits, is at /tools/window-tint-laws. _Front side window VLT minimum, selected states_ | State | Front side window VLT minimum | Category | | --- | --- | --- | | California | 70% | Strict | | New York | 70% | Strict | | Pennsylvania | 70% | Strict | | Florida | 28% | Moderate | | Texas | 25% | Moderate | | Arkansas | 25% | Moderate | | Montana | 24% | Lenient | | New Mexico | 20% | Lenient | > A film percentage that is legal in Texas or Florida can be an automatic ticket in California or New York. Always check the law in the state where the car is registered. ## Windshield, reflectivity and color rules most states share Almost every state follows the same basic windshield rule: a non-reflective strip is allowed above the factory AS-1 line, or within the top 4 to 6 inches if there is no AS-1 line, and that strip usually needs to meet a 70 to 88 percent VLT standard of its own depending on the state. California, for example, requires the glazing material itself to carry at least 88 percent VLT for UV-protective film placed above that line. Reflectivity caps and color bans are nearly universal. Most states cap front window reflectivity at 20 to 35 percent and prohibit red, amber, gold or mirrored finishes outright, regardless of how light the VLT percentage is. A legally dark-enough film can still fail inspection for being too reflective or the wrong color. ## Medical exemptions and how they actually work Most states, including California under Vehicle Code 26708, let a driver or regular passenger use darker front window tint than the general law allows if they carry a signed letter from a licensed physician certifying a medical need to be shielded from direct sun, such as lupus or a photosensitivity condition. A dermatologist's certification can also qualify for UV-protective film exemptions in some states. The exemption usually has conditions: the letter has to be carried in the vehicle, some states require pre-approval or a sticker, and most explicitly state that the exemption does not apply to driving after dark, since the point is sun protection, not general privacy. ## How to check before you book an install Confirm your state's front, rear and windshield VLT limits, and whether your state checks the glass-plus-film reading or the film's labeled percentage alone. Texas, for instance, writes its 25 percent minimum under Transportation Code 547.613 as a combined light transmission and reflectance standard, not just a film rating. Use /tools/window-tint-laws to pull the limit for your exact state, then use /tools/tint-percentage-simulator to see what a legal percentage actually looks like on your vehicle before you commit to a film. A reputable installer will also know the local limit, but the final ticket risk is on the driver, not the shop. Keep a copy of your receipt or installer invoice listing the film's labeled VLT percentage. If an officer's meter reads a point or two different from the labeled percentage due to normal measurement variance, documentation showing you installed a compliant film can help resolve the stop faster. ## Frequently asked questions **Q: What happens if my tint is darker than my state allows?** A: You can be cited for an equipment violation, and in most states you will be required to prove it was removed or brought into compliance, sometimes with a follow-up inspection, on top of any fine. **Q: Does the tint law follow the car or the driver?** A: It follows where the vehicle is registered and primarily driven. If you move to a stricter state, previously legal tint can become a violation and may need to be removed or replaced. **Q: Can I use a darker tint just on the rear windows?** A: Usually yes. Most states set a lighter minimum VLT for front side windows than for rear side and rear windows, and several states have no VLT limit at all for rear windows once dual side mirrors are installed. **Q: Is factory-tinted glass counted differently from aftermarket film?** A: No, VLT laws measure the combined reading of the glass and any film applied to it, so factory-tinted glass still has to meet the same minimum once aftermarket film is added. **Q: Do medical exemptions let me use any tint percentage?** A: No. Exemptions typically allow a darker but still specific percentage or require the fitting to be documented, and nearly all states still bar use of the exemption for night driving. **Q: Where can I check my exact state's limit?** A: The full 50-state chart with current VLT limits is at /tools/window-tint-laws, which is faster and more reliable than relying on a single blog post. **Q: Can I install a tint percentage that's legal in a neighboring state?** A: No, only the law in the state where the vehicle is registered and primarily driven applies, regardless of what a neighboring state allows. ## Sources - [California Legislative Information, Vehicle Code Section 26708](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=VEH§ionNum=26708) - [FindLaw, Texas Transportation Code Section 547.613](https://codes.findlaw.com/tx/transportation-code/transp-sect-547-613/) - [Tint Wiz, vehicle window tint laws by state](https://tintwiz.com/window-tint-laws-by-state) - [Gilroy Blackout, window tint laws in all 50 states, 2026 VLT chart](https://gilroyblackout.com/blog/window-tint-laws-by-state-2026/)
