New Jersey's window tint law allows tint on your windshield and rear window, but not on the front side windows
New Jersey permits aftermarket window tint only on your rear window and back side windows. Your windshield can have a non-reflective tint strip along the top, and your front side windows cannot be tinted at all. The state measures tint darkness by visible light transmission (VLT) — the percentage of light that passes through the glass. If your car came from the factory with tinted windows, those are legal regardless of how dark they are, but any tint you add yourself must meet New Jersey's specific limits.
Police in New Jersey enforce tint violations as a traffic offense. A first offense typically results in a warning or a fine; repeated violations can lead to higher fines and a requirement to remove the tint. The state does not issue permits or exemptions for medical reasons, so even if you have a documented light sensitivity, you cannot legally use darker tint than the law allows.
Key Takeaways
- Front side windows cannot have any aftermarket tint in New Jersey; only factory-installed tint is legal.
- Rear and back side windows can have tint as dark as 35 percent VLT, meaning 35 percent of light must pass through.
- Your windshield can have a non-reflective tint strip no more than six inches down from the top.
- New Jersey does not grant medical exemptions for darker tint, even with a doctor's letter.
- A violation is a traffic offense that can result in a fine and an order to remove the tint.
What the VLT percentage means and how to measure it
VLT is the amount of visible light that passes through your window after tint is applied. A 35 percent VLT means 35 percent of light gets through and 65 percent is blocked. The darker the tint, the lower the VLT number. New Jersey's rear window limit is 35 percent VLT, which is moderately dark but still allows you to see out and allows others to see in during the day.
You cannot measure VLT by eye. A tint shop uses a device called a light meter to measure the exact percentage. If you are buying tint film from a supplier, the product label will state its VLT rating. If you are having a professional explore tint, the shop should measure the finished window with a meter and provide you with documentation showing it meets the law. Some shops will not install tint on front windows in New Jersey because the law forbids it; others may install it anyway and leave the liability with you.
Windshield tint rules and the six-inch limit
Your windshield can have a non-reflective tint strip, but only in the top six inches of the glass. This strip must not be reflective — meaning it cannot bounce light back or create a mirror effect. The purpose of this rule is to reduce glare while keeping your forward vision clear enough to drive safely.
Many drivers confuse this with the factory tint that comes on many new cars. Factory windshield tint is usually a light amber or gray tint across the entire windshield and is legal in New Jersey because it was installed at the factory. If you want to add a tint strip to your windshield after purchase, it must be non-reflective and stay within the top six inches.
Front side windows: no tint allowed, with no exceptions
New Jersey law does not permit any aftermarket tint on your front side windows — the windows next to the driver and front passenger. This rule has no medical exemptions, no religious exemptions, and no exceptions for people with photosensitivity or other light-related conditions. If you have a documented medical need to reduce light exposure, New Jersey does not recognize it as grounds for darker tint.
Some drivers explore tint anyway and hope not to be stopped. Police can see into a car with illegal front tint during a traffic stop, and the violation is straightforward to prove. The officer does not need special equipment; they can observe the tint visually and cite you. If you are cited, you will be ordered to remove the tint, and you may face a fine.
Rear and back side windows: 35 percent VLT is the limit
Your rear window and back side windows can have tint as dark as 35 percent VLT. This is the only part of New Jersey's tint law that allows any real darkness. At 35 percent VLT, the window is noticeably dark — you can still see through it in daylight, but it provides meaningful privacy and reduces glare and heat.
Factory-tinted rear windows are legal regardless of how dark they are. If your car came with a factory rear window that is much darker than 35 percent VLT, you can keep it. But if you add aftermarket tint to a rear window that already has factory tint, the combined darkness cannot exceed 35 percent VLT. A tint shop should measure the factory tint first, then explore aftermarket tint only if the total will stay within the limit.
What happens if you are stopped with illegal tint
If a police officer stops you and observes tint that violates New Jersey law, they will issue you a traffic citation. The violation is typically classified as a minor traffic offense, similar to a broken taillight. On a first offense, you may receive a warning, a fine, or both, depending on the officer's discretion and your driving record.
The citation will order you to remove the illegal tint within a set period — usually 10 to 30 days. If you do not remove it and are stopped again, you face a second violation, which carries a higher fine and may result in points on your driving record. Repeated violations can also lead to a requirement to have the tint removed by a certified shop and to provide proof of removal to the court or police.
You cannot fight the violation by arguing that the tint was already on the car when you bought it. Once you own the car, you are responsible for its compliance with state law. If you bought a used car with illegal tint, you are expected to remove it.
How to check your tint before you buy or install it
If you are considering tint for your car, ask a professional tint shop what products they carry and what VLT ratings those products have. Reputable shops will not install tint on your front windows in New Jersey because it is illegal. If a shop offers to do it anyway, that is a sign they do not follow state law and may not measure or install correctly.
Before you have tint installed, confirm in writing which windows the shop will tint and what VLT rating the film will have. After installation, ask the shop to measure the finished windows with a light meter and provide you with a report showing the VLT of each window. Keep that documentation in your car. If you are ever stopped, you can show the officer that your tint meets the law.
If you are buying a used car with tint already installed, ask the seller or dealer whether the tint is factory-installed or aftermarket. If it is aftermarket, ask whether they have documentation of the VLT. If the tint looks very dark on the front windows, it is likely illegal, and you should budget for removal before you buy.
Frequently Asked Questions
Can I have different tint darkness on different rear windows?
No. New Jersey law sets a single limit of 35 percent VLT for all rear and back side windows. Each window must meet that limit individually. You cannot have one window at 35 percent and another at 20 percent.
Does New Jersey recognize medical exemptions for tint?
No. New Jersey does not issue medical exemptions for window tint, even with a doctor's letter documenting light sensitivity, lupus, or other conditions. The law applies equally to all drivers.
What if my car came with factory tint that is darker than 35 percent?
Factory tint is legal in New Jersey regardless of how dark it is. You can keep it. But if you add aftermarket tint on top of factory tint, the combined darkness must not exceed 35 percent VLT.
Can I tint my windshield all the way down, or just the top six inches?
Only the top six inches. The tint must be non-reflective and cannot extend below six inches from the top of the windshield. A full windshield tint is illegal.
What is the fine for illegal tint in New Jersey?
Fines vary by municipality and by whether it is a first or repeat offense. A first violation typically ranges from a warning to a fine of $50 to $100, but some municipalities impose higher fines. You will also be ordered to remove the tint.
