Yes, tinted windows are illegal in NJ when the tint is aftermarket film applied to the front windshield or the front side windows. New Jersey allows no minimum darkness on those windows; any visible film violates the statute unless you hold a medical exemption from the Motor Vehicle Commission. Rear side windows and the back window are a different story and can be tinted as dark as you like.
Which Windows the Ban Covers
N.J.S.A. 39:3-74 prohibits placing any “non-transparent material” on the front windshield, front side windows, deflectors, and corner lights adjoining the windshield.1Justia Law. New Jersey Revised Statutes Title 39 Section 39-3-74 For everyday drivers that means no tint of any shade on the windshield or the two front door windows. There is no VLT percentage that makes front-window tint legal in New Jersey. Even a light film violates the statute.
The rule applies the same way to sedans, SUVs, trucks, and vans. Some states carve out multi-purpose vehicles; New Jersey does not.
Behind the driver’s seat, the rules relax. Back side windows and the rear window can carry tint of any darkness because the statute restricts only the front.1Justia Law. New Jersey Revised Statutes Title 39 Section 39-3-74 That is why dark “privacy glass” on SUVs and minivans is common on New Jersey roads.
The Narrow Windshield Exception
The only tint allowed on the windshield itself is a non-reflective strip along the top edge, above the manufacturer’s AS-1 line etched into the glass.2New Jersey Motor Vehicle Commission. Medical Exemption for Vehicle Sun-Screening Information Below that line the windshield must stay clear.
Factory Glass Is Not Aftermarket Film
Factory-installed privacy glass on rear windows is legal. That glass is tinted during manufacturing as part of the glazing itself rather than by applying a film, so it is not “non-transparent material” added to the vehicle. If your car came from the dealer with dark rear glass, you do not need to remove it. The statute targets aftermarket film added after the vehicle leaves the factory.
How Police Enforce Tint Violations
Illegal front-window tint is a primary offense, meaning an officer can pull you over solely because your front windows look too dark. In State v. Smith (2022), the New Jersey Supreme Court held that reasonable suspicion of a tint violation arises when a front windshield or front side window is so darkly tinted that police cannot clearly see people or objects inside the vehicle. Officers do not need a tint meter to justify the stop, and the court rejected the argument that “non-transparent” was too vague to enforce.3Justia Case Law. New Jersey v. Smith 2022 Supreme Court of New Jersey Decisions
Fines and Inspection Consequences
A window tint violation is a non-moving offense and adds no points to your driving record.4State of New Jersey. NJ Points Schedule The fine for driving with illegal tint on the front windshield or front side windows is capped at $100.5New Jersey Legislature. NJ Legislature A2233
The bigger cost usually comes from state inspection. Illegal tint will cause your vehicle to fail. When it fails, the MVC places a red sticker on the windshield, and you have until one month from the last day of the month shown on the sticker to fix the problem and return for re-inspection. Police can issue a separate summons any time they stop you while a failed sticker is displayed.6New Jersey Motor Vehicle Commission. NJ MVC What If My Vehicle Failed Inspection Professional tint removal typically runs $100 to $500 depending on the number of windows and the type of film, so the total cost of illegal tint can be several times the ticket itself.
Medical Exemption for Sun Sensitivity
If a medical condition makes you especially sensitive to sunlight, you can apply to the MVC for permission to tint the front windshield and front side windows. The MVC lists qualifying diagnoses that include lupus erythematosus, solar urticaria, porphyria, polymorphous eruption, persistent light reactivity, and actinic reticuloid.2New Jersey Motor Vehicle Commission. Medical Exemption for Vehicle Sun-Screening Information
Applying and Renewing
You complete the MVC Sunscreening application, have your physician fill out the medical portion and provide a valid prescription, and submit everything to the MVC’s Customer Advocacy Office. The application form is available at SUNSCREENING@mvc.nj.gov or by calling 609-984-2973.7New Jersey Motor Vehicle Commission. NJ MVC Window Sun-Screening For Medical Reasons
If you qualify, the MVC issues a temporary approval valid for 60 days along with a Sunscreening Installation Confirmation form. After professional installation and return of the confirmation, you receive a permanent certificate valid for 48 months.7New Jersey Motor Vehicle Commission. NJ MVC Window Sun-Screening For Medical Reasons Renewal applications must go in no later than 30 days before expiration, and the MVC will not renew if the film has developed haze, discoloration, or other visual distortion.8Legal Information Institute. NJ Admin Code 13-20-1-6 – Medical Exemption Certificate Period Any medical sun-screening on the windshield must still sit above the AS-1 line.2New Jersey Motor Vehicle Commission. Medical Exemption for Vehicle Sun-Screening Information
Keep the Certificate in the Car
The approval document has to travel with the vehicle. If you are stopped, the officer will expect to see it. Driving with an approved exemption but without the certificate is treated as a separate violation, though the court is not permitted to impose court costs for that offense.7New Jersey Motor Vehicle Commission. NJ MVC Window Sun-Screening For Medical Reasons
If You Are Driving Through from Another State
Tint that is legal in your home state will not protect you in New Jersey. State traffic laws apply to every vehicle on New Jersey roads regardless of registration, and an officer who cannot see through your front windows has the same basis to stop a Florida plate as a New Jersey plate.
Commercial Vehicles
Drivers of commercial motor vehicles carry an extra federal layer. Under Federal Motor Carrier Safety Administration rules, windshields and side windows on commercial vehicles may be tinted only if light transmission is at least 70 percent.9Federal Motor Carrier Safety Administration. May Windshields and Side Windows Be Tinted Because New Jersey already bans all aftermarket tint on front windows, commercial drivers in the state face two overlapping prohibitions at once.
