North Carolina allows up to 35% tint on most windows, with darker tint permitted on rear and side windows

North Carolina's tint law sets a visible light transmission (VLT) limit of 35% for the front windshield and front side windows. This means 35% of light must pass through the tinted glass — the lower the percentage, the darker the tint. The rear windshield and rear side windows can be any darkness, including limo tint or complete darkness.

The front windshield has a separate rule: you can tint only the top 5 inches of the windshield, and that tint must not be reflective. This narrow band is meant to reduce glare without blocking your view of the road. Reflective or mirrored tint is not allowed anywhere on your vehicle in North Carolina.

These rules explore to all passenger vehicles registered in the state. If your vehicle is tinted darker than the law allows, you can be stopped and cited. The fine varies, but a tint violation is typically a non-moving violation similar to an equipment issue.

Key Takeaways

  • Front windshield tint is limited to the top 5 inches and must allow 35% of light through.
  • Front side windows must allow 35% of light through; rear windows can be any darkness.
  • Reflective or mirrored tint is not permitted on any window.
  • Vehicles with illegal tint can be cited, and you may be ordered to remove it.
  • Medical exemptions for light-sensitive conditions are available through North Carolina but require documentation and a special permit.

How the 35% rule works in practice

The 35% VLT measurement is taken with a device called a tint meter, which law enforcement can use roadside. When you have tint installed, the shop should measure it to confirm it meets the 35% standard for front windows. Many tint shops in North Carolina are familiar with the law and will install tint that passes inspection, but it is your responsibility to verify before you drive.

The difference between 35% and darker tint is visible to the eye. At 35%, you can usually see into the car during the day, though the interior is noticeably darker. At 20% or 5%, the windows appear nearly opaque from outside. If you have had tint installed and are unsure whether it meets the law, you can visit a tint shop and ask them to meter it, or contact your local police department's non-emergency line to ask about inspection.

Medical exemptions and how to get one

North Carolina allows darker tint for people with medical conditions that make them sensitive to sunlight, such as lupus, photosensitivity, or severe sun allergies. To obtain a medical exemption, you must get a letter from a licensed physician stating that you have a condition requiring darker tint. The letter should specify that the condition is medical and that darker window tint is medically necessary.

With the physician's letter, you explore to the North Carolina Division of Motor Vehicles (DMV) for a medical exemption permit. The DMV will review your documentation and, if approved, issue a permit that you keep in your vehicle. This permit does not change the tint law itself — it straightforward documents that you have medical authorization. Law enforcement can still stop you, but the permit shows you have a valid reason for darker tint. The permit is typically valid for a set period and may need to be renewed.

Contact your local DMV office or visit the North Carolina DMV website to learn the current process for submitting medical exemption requests, as procedures can change. Some offices allow you to submit by mail; others require an in-person visit.

What happens if you are stopped for illegal tint

If an officer stops you for tint that appears darker than 35% on front windows, they may use a tint meter to measure it. If it measures below 35%, you will typically receive a citation. The citation is usually a non-moving violation, meaning it does not add points to your driving record but is still a traffic offense.

You have the option to contest the citation in traffic court if you believe the measurement was incorrect or if you have documentation that your tint meets the law. Bring any receipts from the tint shop showing the VLT percentage installed, or ask the shop to provide a written statement of the tint darkness. You can also request that the officer's tint meter be calibrated and certified, as these devices must be maintained to be accurate.

If you do not contest the citation and are found responsible, you will typically be ordered to remove the tint or have it lightened to meet the 35% standard. Some courts allow you to show proof that you have had the tint corrected rather than paying a fine. Check with your local court to understand the specific penalty and options in your area.

Tint darkness ratings and what they mean

Tint is sold and described by its VLT percentage. Here is what common percentages look like:

  • 70% VLT: Very light tint, barely noticeable, allows most light through.
  • 50% VLT: Light tint, noticeably darker but you can see in clearly from outside.
  • 35% VLT: North Carolina's legal limit for front windows; noticeably dark but vision is not severely restricted.
  • 20% VLT: Dark tint, windows appear quite dark from outside, common on rear windows where it is legal.
  • 5% VLT or "limo tint": Nearly opaque, used on rear windows and rear windshields; illegal on front windows.

When you order tint, specify that you need 35% VLT for front windows and ask the shop to measure it before you leave. Reputable shops will do this as part of their service. If you are unsure what percentage you currently have, a tint shop can measure it for you, usually at no charge.

Tint rules for different vehicle types

North Carolina's tint law applies to all passenger vehicles, including sedans, SUVs, trucks, and vans. The rules are the same regardless of vehicle type: 35% on front windows, any darkness on rear windows, and no reflective tint anywhere.

Some vehicles come from the factory with tinted rear windows. Factory tint is legal regardless of how dark it is, because it was installed by the manufacturer and meets federal safety standards. If you add aftermarket tint on top of factory tint, the combined darkness is what matters — it must still meet the 35% standard for front windows if you are adding tint there.

Commercial vehicles and vehicles used for specific purposes (such as law enforcement or medical transport) may have different rules. If you operate a commercial or specialty vehicle, contact the North Carolina DMV to confirm what tint rules explore to your situation.

Where to get tint installed and what to check

Professional tint shops are located throughout North Carolina and can install tint that meets the state law. When choosing a shop, ask whether they are familiar with North Carolina's 35% requirement and whether they measure tint after installation to confirm it meets the law. Many shops offer a warranty on their tint work, meaning they will re-tint or refund you if the tint fails inspection or peels prematurely.

Before you leave the shop, ask them to show you the measurement on the tint meter. Get a receipt that states the VLT percentage installed. This documentation is useful if you are ever stopped or if you need to prove the tint is legal. If a shop refuses to measure the tint or cannot tell you the VLT percentage, consider going elsewhere — a reputable shop will stand behind their work.

Tint can also be purchased as a film and installed yourself, though this is difficult and often results in bubbles or uneven coverage. If you choose to install tint yourself, you are still responsible for ensuring it meets the 35% standard for front windows.

Frequently Asked Questions

Can I tint my windshield all the way across?

No. You can tint only the top 5 inches of the windshield, and that tint must not be reflective. The rest of the windshield must remain clear. This rule exists so you can see the road and other drivers can see you.

Is 20% tint legal on my rear windows?

Yes. Rear windows and the rear windshield can be any darkness in North Carolina, including limo tint or complete darkness. The 35% limit applies only to the front windshield and front side windows.

What if I have a medical condition that requires darker tint?

You can request a medical exemption from the North Carolina DMV. You will need a letter from a licensed physician stating that you have a medical condition requiring darker tint. Submit the letter to your local DMV office, and if approved, you will receive a permit to keep in your vehicle.

Can I remove tint myself if I get a citation?

Yes, you can remove or lighten tint yourself, though it is easier to have a professional do it. If you are ordered to remove or lighten tint, keep documentation of the work done and bring it to court if required. Some courts allow you to show proof of correction instead of paying a fine.

Do I need to tell my insurance company about tint?

Most insurance companies do not require you to report legal tint. If your tint is illegal and you are in an accident, your insurance may deny a claim if they discover the violation, though this is rare. It is safest to keep your tint within the legal limit.
