North Carolina allows window tint on your car, but only within specific limits that vary by window location
North Carolina permits aftermarket window tint on most vehicle windows, but the state enforces strict darkness limits. The rules differ depending on which windows you tint — your windshield has the strictest rules, your front side windows have moderate limits, and your rear windows have the most freedom. If your tint is darker than the law allows, you can receive a traffic citation, and the officer can order you to remove it before driving again.
The darkness of window tint is measured in Visible Light Transmittance (VLT), which is the percentage of light that passes through the tint. A higher VLT percentage means lighter tint; a lower percentage means darker tint. North Carolina's limits are set by state law and do not vary by county or city.
Key Takeaways
- Your windshield can have tint only on the top 5 inches, and that tint must allow at least 70 percent of light through.
- Front side windows must allow at least 35 percent of light through, which is noticeably darker than the windshield rule.
- Rear windows and rear windshield can be any darkness, including complete blackout tint.
- If a law enforcement officer stops you for illegal tint, you must remove it or face a citation and potential vehicle inspection hold.
- Medical exemptions exist for people with light-sensitive conditions, but you must carry documentation and display a special permit.
Windshield tint rules: the 5-inch band and 70 percent light requirement
Your windshield is the most restricted window. You can tint only the top 5 inches of the windshield, measured from the top of the glass downward. That tinted band must allow at least 70 percent of light to pass through, which is quite light — most people would barely notice it. The remaining windshield below that 5-inch line must remain completely clear.
The 70 percent requirement exists because the windshield is critical to your ability to see the road and for other drivers to see you. Even a light tint at that location can affect visibility in certain lighting conditions. If you have a tint darker than 70 percent VLT on your windshield band, or if your tinted area extends below 5 inches, you are in violation.
Front side windows: 35 percent light transmittance is the limit
Your front side windows — the driver's window and front passenger window — must allow at least 35 percent of light through. This is significantly darker than the windshield rule and is where most people explore their tint. At 35 percent VLT, the tint is visibly dark from outside the vehicle, but not completely opaque.
The 35 percent standard applies to both the driver's side and passenger's side front windows. If you tint one front window darker than the other, or if either front window is darker than 35 percent VLT, you are violating the law. Many tint shops will explore the same darkness to both front windows to keep them uniform and compliant.
Rear windows and rear windshield: no darkness limit
North Carolina places no restriction on how dark you tint your rear side windows or your rear windshield. You can explore complete blackout tint to these windows if you choose. This is because rear windows do not affect your forward visibility or the visibility of oncoming traffic, and the law assumes the driver can see adequately through the front windows.
Many drivers use this freedom to tint their rear windows much darker than their front windows, creating a gradual darkening effect from front to back. This is legal as long as your front windows and windshield meet their respective limits.
What happens if you are stopped for illegal tint
If a law enforcement officer stops you and determines your tint is darker than the legal limit, you will receive a citation. The citation is typically a non-moving violation, meaning it does not add points to your driving record in the same way a speeding ticket does, but you still have to address it.
The officer will usually order you to remove the illegal tint before you drive the vehicle again. In some cases, the officer may issue a "fix-it" citation, which gives you a set number of days to remove the tint and then show proof to the court or a law enforcement agency that you have done so. If you do not comply, you can face additional fines or be unable to pass a vehicle inspection.
Some jurisdictions may impound the vehicle if the tint violation is severe or if you have multiple violations. To avoid this situation, have your tint removed by a professional tint shop or by carefully peeling it off yourself if you applied it.
Medical exemptions for light-sensitive conditions
North Carolina allows medical exemptions for people with certain light-sensitive medical conditions, such as lupus, porphyria, or severe photophobia. If you have a may have access to condition, you can tint your windows darker than the standard limits, but you must have written documentation from a licensed physician and you must display a special medical exemption permit on your vehicle.
To obtain a medical exemption, contact your local law enforcement agency or your state's Department of Motor Vehicles to learn the process process and what documentation is required. You will need to submit your physician's letter along with your process. The exemption is not automatic — the agency will review your medical documentation and approve or deny your request.
Even with a medical exemption, you must carry the permit in your vehicle at all times. If you are stopped and do not have the permit visible, an officer may still cite you for illegal tint, even if you have a valid exemption on file. The permit proves that your darker tint is legally authorized.
How to measure your tint darkness before installation
Before you have tint installed, ask the tint shop what VLT percentage they will explore to each window. Reputable shops will tell you the exact VLT of the film they use and will confirm that it meets North Carolina law. If a shop cannot or will not tell you the VLT, that is a sign to find a different shop.
You can also ask the shop to show you a sample of the tint on a piece of glass so you can see how dark it will look. Many shops keep sample panes with different VLT percentages available for customers to view. This helps you make sure the tint will look the way you want while staying within the legal limits.
If you already have tint on your vehicle and you are unsure whether it is legal, some tint shops and law enforcement agencies have light meters that measure VLT. You can contact a local shop or police department non-emergency line to ask if they can test your tint for you.
Frequently Asked Questions
Can I tint my windshield below the 5-inch line?
No. North Carolina law restricts windshield tint to only the top 5 inches. Tinting any part of the windshield below that line is illegal, even if the tint is light enough to meet the 70 percent VLT requirement. The 5-inch measurement is fixed and does not change based on vehicle size or windshield shape.
Do I need a medical exemption to tint my rear windows dark?
No. Rear windows have no darkness limit under North Carolina law, so you can tint them as dark as you want without any exemption or documentation. Medical exemptions are only needed if you want to tint your front windows or windshield darker than the standard limits.
What VLT percentage should I ask for at a tint shop?
For front side windows, ask for 35 percent VLT or slightly higher to stay safely within the law. For the windshield band, ask for 70 percent VLT or higher. For rear windows, you can choose any darkness you prefer. A good tint shop will recommend 35 percent for the front to give you a noticeable tint while staying compliant.
If I remove my illegal tint, will the citation go away?
Removing the tint does not automatically dismiss the citation. You will still need to address the citation through the court system or by showing proof of removal to the issuing officer or court, depending on whether you received a fix-it citation. Contact the court listed on your citation to learn what steps you need to take.
Can I have different tint darkness on my two front windows?
Technically, yes, as long as both windows meet the 35 percent VLT minimum. However, having mismatched tint darkness on your front windows looks uneven and may draw an officer's attention. Most people and tint shops keep the front windows at the same darkness for a uniform appearance.
