The legal tint rules in NJ draw a hard line at the driver’s row: the front windshield and both front side windows must stay factory-clear, while the rear side windows and back windshield can be tinted to any darkness you want. There is no legal VLT percentage that makes aftermarket film on the front glass acceptable. The only route to darkened front windows is a medical exemption from the Motor Vehicle Commission.
Front Windshield and Front Side Windows
N.J.S.A. 39:3-74 prohibits non-transparent material on the front windshield, side shields, deflectors, and front side windows of any motor vehicle.1Justia. New Jersey Code 39-3-74 – Windshields Must Be Unobstructed and Equipped With Cleaners That language covers aftermarket tint film, spray-on coatings, and anything else that reduces how much light passes through the glass. It applies the same way to sedans, SUVs, trucks, and vans.
The one narrow exception is a strip across the top of the windshield. You can tint that strip as long as it doesn’t extend below the AS-1 marking etched into the glass by the manufacturer, or more than six inches down from the top of the windshield, whichever is lower.2U.S. Environmental Protection Agency. New Jersey Administrative Code Title 13, Chapter 20, Subchapter 33 – Section 13:20-33.7 Below that line, the front glass has to stay clear.
Rear Side Windows and Back Windshield
Behind the driver’s row, New Jersey is more permissive than most drivers expect. Passenger cars and multi-purpose vehicles can carry any darkness level on the rear side windows and back windshield.2U.S. Environmental Protection Agency. New Jersey Administrative Code Title 13, Chapter 20, Subchapter 33 – Section 13:20-33.7 The administrative code only restricts tint on the windshield and the windows “to the immediate right or left of the driver.”
One practical catch: if your rear tint is dark enough to obstruct the view through the back windshield, your vehicle needs dual side mirrors. Most modern vehicles already come with mirrors on both sides, but if yours doesn’t, add one before you install the film.
Reflective and Mirrored Film
Even where any darkness is allowed, mirrored and metallic finishes are not. New Jersey’s equipment rules bar glazing that causes “undue or unsafe distortion of visibility,” and reflective film bounces sunlight and headlight glare into other drivers’ eyes.2U.S. Environmental Protection Agency. New Jersey Administrative Code Title 13, Chapter 20, Subchapter 33 – Section 13:20-33.7 Standard charcoal, ceramic, or carbon films in a non-reflective finish keep you clear of that restriction.
Penalties for Illegal Tint
Illegal tint is an equipment violation under N.J.S.A. 39:3-74. The base statutory fine is up to $25,3New Jersey Courts. Fines and Penalties of Common Motor Vehicle Offenses but court fees, surcharges, and processing costs push the real total higher. Officers can also issue an equipment repair order that requires you to strip the film and prove compliance.
Repeated violations draw more scrutiny, and judges have discretion to impose heavier penalties for continued noncompliance. The cheapest path when you’ve been cited is removing the film before the court date and bringing proof of removal.
Medical Exemption for Front Window Tint
A medical exemption from the MVC is the only lawful way to put tint on your front windshield or front side windows. It’s intended for drivers with conditions that make them unusually sensitive to sunlight, and the MVC lists specific qualifying diagnoses along with a catch-all for other photosensitive disorders certified by a physician.4New Jersey Motor Vehicle Commission. Window Sun-screening For Medical Reasons
The application captures your vehicle details (make, model, year, VIN, and plate) and requires your doctor’s certification along with a valid prescription.5New Jersey Motor Vehicle Commission. Application for Sunscreening Exemption Mail the completed form and prescription to:

Once approved, the tint has to be installed by an authorized professional installer rather than applied at home. The exemption is valid for 48 months, and you need to reapply before it expires.5New Jersey Motor Vehicle Commission.
