How dark your window are allowed to be depends on what state you're driving in. But even then, window tint laws can be confusing.

You may not have realized it, but your car windows are most likely tinted – just about all cars roll off the assembly line with glass featuring some level of tint. Tinting has several benefits, but darker windows also create safety hazards. Because of this, window tint laws exist in every state.

There’s often a great deal of confusion over window tint regulations, primarily because they differ throughout the country. Some states allow for much darker windows than others. It’s important to brush up on these laws, especially if you’re considering adding additional tint to your car’s windows.

What Are Window Tints?

Window tints are thin, dark sheets of film applied to a car’s glass to help keep light out of the cabin. Most new cars come standard with some level of window tinting but aftermarket window tints are available as well.

Tinting serves several purposes. Most notably, it protects against the sun’s harmful UVA rays, which cause skin cancer as well as damage and fading to the vehicle’s interior. Window tints also help keep the cabin temperature cooler, cut down on glare from the sun and headlights, and provide car owners with a level of privacy and security. Some people simply like the way they look.

But with all these benefits comes one major drawback: visibility. The darkness of window tints makes them more difficult to see through, particularly at night, creating a safety hazard.

Window Tint Laws

Are window tints legal?

Laws regulating window tinting in passenger cars are found in every state. These statutes dictate how much light is able to pass through the glass, a measurement known as visible light transmission percentage. The darker the window tint, the lower the percentage. VLT is usually checked as part of your vehicle’s annual state inspection.

The allowable VLT percentage minimum or legal window tint percentage varies from state to state, from 20% in New Mexico to 70% in New York, Rhode Island, California, Pennsylvania, Delaware, Iowa and Washington, D.C. Three states (New Hampshire, New Jersey and Vermont) don’t allow any tinting.

Window tint laws mainly focus on a car’s front side windows, although many states also have rules regarding back side and rear windows. States may allow for more tinting on back side windows, but, if so, usually require a car have dual side mirrors. Rear windows are often permitted to be darker than front side windows, as well.

Nowhere in the country are windshields allowed to be tinted except along the top of the glass pane. How far down the tinting is permitted to extend also varies by state.

Window tint laws can be complicated. For example, Michigan allows any percentage of tinting but only on the top 4 inches of the window. Some states allow tints to include metallic or mirrored elements, but many states ban such products. Further muddling the issue is the fact many states have different tinting laws for sedans than they do for trucks, minivans and SUVs.

It’s best to consult your state’s department of motor vehicles to know the window tint legal limit and what is and isn’t allowed.

Exemptions

Most states allow exemptions to window tints laws for people with medical conditions causing severe light sensitivity. Such conditions include albinism, dermatitis, dermatomyositis lupus, porphyria and drug photosensitivity, among others. If you require a window tint medical exemption, you can apply for one through your state’s department of motor vehicles.

Are Window Tint Laws Applicable if You’re Traveling Through Another State?

When in another state, you’re subject to that state’s laws, including those dictating window tinting. Some states provide exemptions to their tint laws to those just passing through, but many do not. In the latter case, you could be subject to a citation if your windows are too dark. That said, if you explain that you’re only visiting and your windows are in compliance in your home state, you may be able to get off without a ticket.

62 Thoughts on “Everything You Need to Know About Window Tint Laws

  1. While I support the police – why should their windows be tinted if a citizen’s window cannot? Safety is cited- but ambushing of police officers is very rare. We should not have separate laws.

  2. Put all windows half way down as a courtesy to the officer if you are being pulled over and you have tint. They appreciate it. The resulting stop will usually have a different outcome.

  3. Well the story I heard about the NY law was that it began way upstate (possibly Buffalo or at least that far upstate) because a police officer’s wife was concerned that people with nefarious desires might be able to hide weapon(s) when her husband would be approaching a stopped vehicle. With my eyesight, night driving became much easier with the side and rear window tinting that greatly reduced eye strain in one vehicle decades ago.

  4. Article information stating that NJ does not allow any tinting is incorrect. Check the MV regulations: Non-OEM tinting is not allowed on the windshield or driver and passenger side windows. It is allowed on rear side and back windows, with limitations.

  5. As someone who is short, I wish there was a way that windshield and driver side windows could be tinted at least halfway down (or photo-sensitive) to reduce dangerous sunrise/sunset glare problems!! Ciders are never low enough!

  6. I remember when I first moved to Tucson, I got a ticket for tinted windows. When I went to court, there were five others there with the same ticket by the same statie. Bottom line, they were having a training day on “tinted windows” because they had recently had a shooting from the back seat because the officer couldn’t see in.

  7. I don’t understand how I see many NY vehicles w/the blackest of tints…where are they going for inspection. These tints are so black that you can not even identify if theres a driver!!

  8. No tint is legal in NY. A factory window will test at about 75% VLT so any added tint will render the window illegal.
