What Tint Is Legal In Nj

Alright, let's talk about window tint in New Jersey. This isn't about aesthetics alone; it’s a legal matter. Exceed the limits, and you’re looking at fines and the hassle of removing the tint. Consider this your guide to staying compliant and avoiding trouble.

Why This Matters: Staying on the Right Side of the Law

Understanding NJ window tint laws is crucial for a few key reasons:

Avoiding Fines: Non-compliance can result in hefty fines.
Vehicle Inspection: Your car won't pass inspection if your tint is too dark.
Legal Trouble: Although rare, excessive tint could be used as a pretext for a traffic stop.
Resale Value: Illegal tint can negatively impact the resale value of your vehicle.

Key Specs and Main Parts: Understanding the VLT

The core concept is Visible Light Transmittance (VLT). VLT is the percentage of visible light that can pass through the tinted film and the window. A lower VLT means darker tint. Here's the breakdown for New Jersey:

Windshield: Non-reflective tint is allowed along the top edge of the windshield above the AS-1 line (typically marked on the windshield).
Front Side Windows: Must allow more than 70% of light in. In other words, you're essentially limited to the factory tint these windows already have. Adding aftermarket tint to the front side windows is essentially illegal.
Rear Side Windows: Any darkness is permitted.
Rear Window: Any darkness is permitted.

Keep in mind that these regulations are subject to change, so it's always wise to double-check with the New Jersey Motor Vehicle Commission (NJMVC) for the most up-to-date information.

Understanding "Any Darkness" and Factory Tint

While "any darkness" is permitted on the rear windows, don't go overboard. Excessive darkness can still attract unwanted attention from law enforcement. Furthermore, many vehicles come with a slight factory tint. This counts toward your VLT. If your factory windows already have a VLT of 75%, applying a 70% tint film will result in a VLT lower than the legal 70%.

You can measure the VLT with a tint meter, a device that shines a light through the window and reads the percentage of light that passes through. Automotive shops and inspection stations usually have these.

How It Works: The Science of Light and Film

Tint films work by absorbing or reflecting sunlight. The darker the film, the more light it blocks. This is achieved through various materials embedded in the film, such as dyes, metals, or ceramics. These materials interact with the photons of light, reducing the amount of visible light that passes through.

The VLT percentage is a measure of the efficiency of this process. A 5% tint, for example, blocks 95% of the light, allowing only 5% to pass through. This provides excellent privacy and heat reduction but is illegal on the front side windows in New Jersey.

Real-World Use: Troubleshooting and Avoiding Problems

Here are some common issues you might encounter and how to address them:

Bubbling or Peeling: This usually indicates poor installation or low-quality film. Remove the old film carefully (using a heat gun and scraper) and have a professional reinstall it.
Hazy Appearance: This could be due to improper cleaning or using abrasive cleaners. Use a microfiber cloth and a dedicated window tint cleaner.
Failing Inspection: If your tint is too dark, you'll need to remove it and replace it with a compliant film. This often involves a heat gun, scraper, and a lot of patience.
Discoloration: Some cheaper films can fade over time, especially if exposed to excessive sunlight. Invest in a high-quality film to avoid this.

DIY Tinting: Proceed with Caution

While applying window tint yourself is possible, it’s a skill that takes practice. You'll need a heat gun, squeegee, spray bottle with soapy water, and a sharp knife. Here's a simplified process:

Clean the window thoroughly.
Cut the film to the approximate size of the window.
Spray the window with soapy water.
Apply the film, smoothing out any bubbles with the squeegee.
Use the heat gun to shrink and conform the film to the window's shape.
Trim the edges with a sharp knife.

However, achieving a bubble-free, wrinkle-free finish requires experience. Consider having a professional do it to ensure a clean and legal job.

Safety: Heat Guns and Sharp Blades

Working with window tinting materials involves some risks:

Heat Guns: These can cause burns if not used carefully. Wear heat-resistant gloves and avoid prolonged exposure to your skin. Also, be careful not to overheat the glass, as this could cause it to crack.
Sharp Blades: Always use a sharp, new blade to avoid tearing the film. Be extremely careful when cutting near window seals and trim.
Chemicals: Some tint cleaners contain harsh chemicals. Wear gloves and eye protection when using them. Ensure proper ventilation.
Glass Shards: Removing old tint can sometimes result in small glass shards. Wear safety glasses and gloves.

Always disconnect the car battery before starting any electrical work, such as wiring in a tint meter or adding electrical components near the windows.

Legal Exemptions: Medical Necessity

New Jersey does offer exemptions to the tint laws based on medical necessity. To qualify, you need a written certification from a licensed physician stating that darker tint is medically necessary to protect you from a specific medical condition. Keep a copy of this certification in your vehicle at all times.

Remember: Double-Check and Stay Informed

Window tint laws can change, so it's essential to stay updated. Always check the NJMVC website or consult with a local tinting professional before making any modifications to your windows. Using a tint meter after application will confirm that you are within legal limits. Don’t assume that a shop that tints windows is necessarily up to date with the latest laws. It is ultimately YOUR responsibility to make sure the tint on your car is legal.

We have assembled this information to help you navigate the complex world of window tinting laws in New Jersey, helping you stay safe and legal on the road. Remember to always prioritize safety, legality, and responsible vehicle modification.
