New Jersey Window Tint Laws (2026): Legal VLT Limits

In New Jersey, aftermarket tinting on the front side windows and windshield is prohibited by law for most drivers. The back side windows and rear window may be tinted to any darkness.

What is the legal tint limit in New Jersey?

New Jersey's front window tinting rule is the strictest in the United States in one key respect: it does not simply require a high VLT percentage for the front side windows. It prohibits aftermarket tint on those windows entirely. Under NJSA 39:3-74, placing any non-transparent or obscuring material on the windshield or front side windows is banned. That means no film, no spray, and no aftermarket treatment that reduces visibility from the driver or front passenger windows is legal for the vast majority of New Jersey drivers.

A higher VLT percentage means lighter (less dark) tint; a lower VLT percentage means darker tint. In New Jersey, the concept of a minimum VLT percentage for the front does not apply because the starting point is zero aftermarket film.

The rear of the vehicle is handled very differently. Back side windows and the rear window may be tinted to any darkness, giving drivers with SUVs, vans, trucks, and passenger sedans wide flexibility behind the driver's seat. New Jersey's mirror statute, NJSA 39:3-71, is not written as a tint rule: it requires every passenger automobile manufactured after January 1, 1965 and registered in the state to have an interior mirror and an exterior mirror on the driver's side whether or not the rear glass is tinted.

Windshield tint rules in New Jersey

No aftermarket tinting is permitted on the windshield in New Jersey. The same NJSA 39:3-74 prohibition that covers the front side windows applies to the windshield: no material may be applied that reduces transparency or obstructs the driver's view through the glass.

The general prohibition in NJSA 39:3-74 is not written as a VLT percentage or a reflectivity number. It bans non-transparent material outright. Numeric transmittance, reflectance and color limits do exist in New Jersey, but they sit in the MVC rules that govern vehicles holding a medical exemption, and they are covered in the next section. In practice, for a vehicle with no exemption, any film applied to the windshield or front side glass that measurably reduces light transmission or creates a mirrored appearance would be unlawful.

Factory-installed features such as UV-blocking embedded in the glass itself are not aftermarket films and are not affected by this statute. The prohibition applies to products installed after the vehicle leaves the factory.

Medical exemptions

New Jersey does provide a path for drivers who have a genuine medical need for sun-screening on the front glass. Under NJSA 39:3-75.1, the owner or lessee of a vehicle that is driven by or regularly used to transport a person with a medical condition involving ophthalmic or dermatologic photosensitivity may apply to the MVC for permission to have the windshield and windows treated. The application must include a written certification from a certified ophthalmologist or a physician holding a plenary license to practice medicine and surgery in New Jersey or a bordering state. The statute names qualifying conditions including polymorphous light eruption, persistent light reactivity, actinic reticuloid, porphyrins, solar urticaria and lupus erythematosus, along with other photosensitive disorders the director determines.

The exemption is not permission for dark front glass. The rules adopted under NJSA 39:3-75.2 and published by the MVC at NJAC 13:20-1 set ceilings that apply even to an exempt vehicle:

• Windshield film may not reduce visible light transmittance below 70 percent, except on the portion of the windshield above the AS-1 line (NJAC 13:20-1.2(a) and (b)).
• Front side window film may not reduce visible light transmittance below 60 percent (NJAC 13:20-1.2(c)).
• A readily removable strip on the uppermost six-inch portion of the front side windows may go down to 35 percent visible light transmittance, but only between sunrise and sunset (NJAC 13:20-1.2(d)).
• Visible light reflectance of film on the windshield or front side windows may not exceed eight percent (NJAC 13:20-1.3).
• Windshield film must be clear film; front side window film may be clear or tinted (NJAC 13:20-1.4).

The exemption must be obtained from the New Jersey Motor Vehicle Commission (MVC) before any film is applied to the front side windows. Simply having a doctor's letter in the glove box is not enough. The formal MVC exemption is required, the certificate or card is valid for no more than 48 months under NJSA 39:3-75.2(b), and it must be kept in the vehicle and exhibited to a law enforcement officer or a motor vehicle examiner on request.

Without this formal exemption, any aftermarket front side tint is illegal regardless of medical circumstances. Drivers who believe they qualify should contact the MVC and have their physician prepare the required certification before scheduling the installation.

How tint is measured and certified

For a vehicle with no medical exemption, New Jersey's front window rule is a flat prohibition rather than a VLT percentage floor, so enforcement does not depend on a meter reading confirming a specific percentage. An officer can cite a vehicle if any film is observed on the front side windows or windshield.

For the rear windows, where any darkness is permitted, there is no VLT measurement requirement. No measurement tolerance is specified in the statute because no minimum percentage applies to those windows.

There is no compliance sticker or installer certification label for ordinary rear window tinting. A label requirement does exist, but it is scoped to medical exemption installs. NJSA 39:3-75.2(c) directs the MVC to require an appropriate label on each windshield and window to which an approved material is applied, and NJAC 13:20-1.8 implements it: a one inch by one inch label carrying the sun-screening product manufacturer's name and the registration number of the installation facility, attached to the lower right corner of the windshield and to the lower corner of each front side window. For vehicles that do have rear tinting, keeping the installer's documentation noting the film type and VLT can help demonstrate that no prohibited front window film is present.

Penalties for illegal tint in New Jersey

Front tint that is not covered by a medical exemption is charged as a violation of NJSA 39:3-74, the windshield obstruction provision. The New Jersey Courts Statewide Violations Bureau Schedule (updated July 29, 2021) lists that offense, "Obstruction of windshield for vision," at $55.00 payable. NJSA 39:3-79, the general penalty provision for this article of Title 39, sets a fine not exceeding $25 for violations of the article.

A much larger fine schedule exists in NJSA 39:3-75.3, but it applies to a different situation. Subsection (b) sets fines not to exceed $1,000 for a first offense and $5,000 for a second or subsequent offense only for violations of the regulations adopted under subsections c. and d. of NJSA 39:3-75.2. Those subsections govern how approved sun-screening material is installed and labeled and the registration of the businesses that install it, so that schedule reaches installers and registered installation facilities operating under the medical exemption program rather than an ordinary driver who tinted the front windows with no exemption at all. The driver-facing penalty in that program is in subsection (a): failing to exhibit a valid exemption certificate carries a fine not exceeding $100, and the municipal court judge may dismiss the charge if the driver produces a certificate that was valid on the day of the charge.

Officers may cite a driver during any traffic stop or vehicle inspection. There is no automatic fix-it ticket mechanism described in the statute. Removing the film promptly after a citation is advisable to avoid a repeat offense.

If you want to tint your windows in New Jersey

If you own a vehicle registered or driven in New Jersey, the safest approach is to leave the front side windows and windshield entirely free of aftermarket film unless you hold a valid MVC medical exemption.

For the rear windows, any VLT darkness is legal, giving you broad choices for privacy and UV protection. When selecting a rear film, confirm that your installer understands the front prohibition and will not apply film to any window forward of the driver's seat.

If you have a photosensitivity condition, start the exemption process before booking an installation appointment. Contact the New Jersey MVC, have your physician or ophthalmologist prepare the NJSA 39:3-75.1 certification, submit the documentation to the MVC, and carry the approved permit in the vehicle at all times. Note that the exemption still limits how dark the film may be, so discuss the NJAC 13:20-1 transmittance and reflectance ceilings with your installer.

If you purchased a vehicle from out of state that already has front side tint installed, note that out-of-state tint is not grandfathered under New Jersey law. You may need to have non-compliant film removed to avoid a citation once the vehicle is operated in New Jersey.
