North Dakota Window Tint Laws: Complete Legal Guide

North Dakota Window Tint Laws: Complete Legal Guide

Window tint can enhance your vehicle's appearance and provide protection from UV rays, but North Dakota has specific rules about how dark your tint can be. Violating these laws can result in traffic citations, fines, and failed vehicle inspections. Understanding the regulations before you tint your windows helps you stay compliant and avoid costly penalties.

Quick Reference Table

Understanding VLT (Visible Light Transmission)

VLT percentage measures how much light passes through your window tint. A higher percentage means lighter tint that lets more light through, while a lower percentage means darker tint that blocks more light. For example, 70% VLT allows 70% of sunlight to pass through the tint, while 50% VLT only allows half the light to pass through.

Think of VLT like a dimmer switch for your windows. North Dakota's regulations use VLT percentages to ensure drivers maintain adequate visibility while still gaining some of the benefits of window tinting. The closer you get to the legal limit, the more protection from UV rays and heat you'll achieve without breaking the law.

Front Windshield Rules

North Dakota allows tinting on the front windshield, but only with specific restrictions. You can apply non-reflective tint to the top portion of your windshield above the AS-1 line (the line where the windshield's curvature changes). This tinted area must allow at least 70% of light to pass through.

The AS-1 line is the critical measurement point here. Some vehicles have this line clearly marked by the manufacturer, while others may not. If you're unsure about your vehicle's AS-1 line, a professional tint installer at a certified shop can help you identify it before applying tint. This limitation protects driver visibility while still allowing you to add some tint to reduce glare.

Side Window Rules

North Dakota distinguishes between front and rear side windows with different legal limits. Your front side windows (driver and passenger windows) can be tinted to a minimum of 50% VLT. This means you can apply tint that blocks up to 50% of light, which provides meaningful UV and heat protection while maintaining good visibility.

Rear side windows have no legal restrictions in North Dakota, so you can tint them as dark as you want. This gives you flexibility in the back of your vehicle while keeping the driving area with adequate visibility. Many drivers take advantage of this by going very dark on rear windows for additional privacy.

Rear Window Rules

Your rear window falls under the same rules as rear side windows in North Dakota—there are no darkness restrictions. You can apply tint at any VLT percentage to your rear window, including complete blackout tint if you prefer. Some drivers use this area for maximum privacy and heat reduction since they don't need to see out the back directly while driving.

If your vehicle has dual side mirrors, you have additional flexibility with rear window tinting. Since dual mirrors allow drivers to see behind the vehicle without relying on the rear window, North Dakota's law permits complete freedom in tinting the rear window regardless of mirror configuration.

Restricted Tint Colors

North Dakota restricts certain tint colors to maintain safety and allow law enforcement to identify vehicles. Red tint is prohibited on any windows, as red tint can interfere with the visibility of brake lights and create confusion for other drivers. Amber or yellow tint is also restricted.

You can apply clear, gray, bronze, or neutral-toned tints without legal concerns. Always verify the specific color of any tint product before purchase, as manufacturers sometimes use names that don't accurately describe the actual color. When in doubt, stick with neutral colors like gray or bronze to ensure compliance.

Medical Exemptions

North Dakota does allow medical exemptions for window tint that would otherwise violate state law. If you have a documented medical condition that requires protection from sunlight—such as photosensitivity, lupus, or certain skin conditions—you may be eligible for a medical exemption permit.

To obtain a medical exemption, you'll need a physician's letter documenting your medical condition and explaining why enhanced window tinting is medically necessary. You then submit this documentation to your local law enforcement agency or the North Dakota Highway Patrol. Once approved, you receive a medical exemption permit that you must carry in your vehicle. This permit allows you to exceed the normal VLT limits for medical reasons, but you should still follow best practices by having a certified installer apply your tint.

Penalties for Illegal Tint

Getting pulled over with illegal window tint in North Dakota can result in a citation carrying a fine. Law enforcement officers can issue a fix-it ticket, which gives you the opportunity to correct the violation and have it dismissed if you comply within the specified timeframe.

If you don't address a fix-it ticket, the violation appears on your driving record and a fine is assessed. Illegal tint can also result in your vehicle failing inspection, preventing you from registering it. Some drivers choose to remove illegal tint when stopped by law enforcement to avoid complications during registration renewal. The key is addressing any violations promptly to avoid escalating penalties.
