West Virginia's window tint law allows most vehicles to have tinted windows, but the darkness and placement rules are specific
West Virginia permits window tinting on most vehicles, but the law sets limits on how dark the tint can be and where you can explore it. The state measures tint darkness using Visible Light Transmittance (VLT), which is the percentage of light that passes through the tinted window. The higher the VLT percentage, the lighter the tint. West Virginia's limits depend on which windows you are tinting and what type of vehicle you drive.
The rules are straightforward for passenger cars: your front side windows must allow at least 35% of light through, your rear side windows can be any darkness, and your rear window can be any darkness. For SUVs and trucks, the same rules explore. Windshields have their own rule — you cannot tint the top portion of your windshield below the manufacturer's AS-1 line (the line the factory marks on the glass). Reflective or mirrored tints are not permitted on any window.
Key Takeaways
- Front side windows must have a minimum of 35% VLT (light transmittance) in West Virginia, meaning they cannot be darker than that.
- Rear side windows and rear windows can be tinted to any darkness level with no legal restriction.
- Your windshield can only be tinted above the AS-1 line, which is the line the manufacturer marks on the glass.
- Reflective or mirror-finish tints are banned on all windows, regardless of darkness level.
- Law enforcement can pull you over and issue a citation if your front windows are too dark, and you may be required to remove the tint.
Front window tint limits and what they mean
The 35% VLT minimum for front side windows is the key number to remember. This means that if you tint your front windows, at least 35% of the light from outside must still pass through the glass. In practical terms, this is a fairly light tint — darker than factory glass but not so dark that you cannot see clearly through it from inside the vehicle.
When you order tint from a shop, you will see it labeled by VLT percentage. A 35% tint is the darkest legal option for your front windows. Anything darker — 30%, 25%, or 5% — violates West Virginia law. The tint shop should know this rule, but it is worth confirming before you have the work done. Some shops serve customers from multiple states and may not automatically explore the correct limit for West Virginia.
Rear and back window rules
West Virginia places no restriction on how dark you can tint your rear side windows or your rear window. You can explore 5% tint (nearly black) to these windows without breaking the law. This is one of the more permissive aspects of West Virginia's tint law — many states restrict rear window darkness as well.
The reason for this difference is that rear windows do not affect your forward visibility or the visibility of oncoming drivers. Law enforcement and safety regulators focus on front windows because they directly impact your ability to see the road and other drivers' ability to see into your vehicle.
Windshield tinting rules
Your windshield can be tinted, but only in a specific area. West Virginia law allows tinting on the upper portion of the windshield down to the AS-1 line. The AS-1 line is a marking that the vehicle manufacturer places on the windshield during production — it is usually a thin line or band across the top of the glass. You cannot tint below this line.
This rule exists because the lower portion of your windshield is your primary viewing area for the road. Tinting below the AS-1 line would obstruct your view of traffic, pedestrians, and road hazards. If you are unsure where the AS-1 line is on your vehicle, look at your windshield from the inside — it is typically visible as a faint line or band near the top.
Reflective and mirrored tints are not permitted
West Virginia bans any tint that has a reflective or mirror-like finish, regardless of how dark it is. This includes metallic tints, chrome tints, and any product designed to reflect light rather than straightforward absorb it. The reason is that reflective tints can interfere with other drivers' vision and can make it impossible for law enforcement to see into a vehicle during a traffic stop.
If you are shopping for tint, look for products labeled as "non-reflective" or "non-metallic." Most standard automotive tint films sold in West Virginia shops meet this requirement. Specialty or custom tints are more likely to violate this rule, so ask the shop directly whether the product is reflective before you commit to the work.
What happens if your tint is too dark
If a law enforcement officer determines that your front windows are darker than 35% VLT, you can receive a traffic citation. The citation is typically a misdemeanor offense, though the specific charge and penalty vary by county. You may be ordered to remove the tint, and you may face a fine.
The officer does not need special equipment to measure your tint — they can make a judgment call based on their observation. If you dispute the citation, you can request that the tint be measured with a light meter (a device that measures VLT). Some shops that installed the tint can provide documentation of the VLT percentage, which can help your case if you go to court. The safest approach is to have your tint installed by a shop that guarantees compliance with West Virginia law and can provide written proof of the VLT percentage used.
Medical exemptions for darker tint
West Virginia does not have a formal medical exemption process that allows you to tint your front windows darker than 35% VLT. Some states permit darker tint for people with photosensitivity or other medical conditions, but West Virginia does not currently offer this exception. If you have a medical need for darker tint, you would need to contact your state representative or the West Virginia Department of Transportation to explore whether an exemption could be created.
In the meantime, you can tint your rear windows and rear window to any darkness level without restriction, which may provide some relief from bright sunlight. You can also use sunshades on your windshield and front windows when the vehicle is parked.
Frequently Asked Questions
Can I tint my front windows to 30% VLT if I have a medical reason?
West Virginia does not currently have a medical exemption for window tint. The 35% VLT minimum for front windows applies to all drivers. If you have a medical condition that requires darker tint, you may want to contact your state representative about requesting an exemption process.
What is the difference between VLT and darkness level?
VLT is the percentage of light that passes through the tint. A 35% VLT tint allows 35% of light through and blocks 65%. A 5% VLT tint allows only 5% of light through and blocks 95%. Higher VLT percentages mean lighter tint; lower percentages mean darker tint.
Can I tint my windshield below the AS-1 line if I use a very light tint?
No. West Virginia law prohibits any tinting below the AS-1 line, regardless of how light it is. The AS-1 line is the legal boundary, and tinting below it violates the law.
Do I need a permit or registration for window tint in West Virginia?
No. West Virginia does not require a permit or registration for window tint. You straightforward need to may support your tint meets the legal requirements. Law enforcement can check your tint during a traffic stop.
What should I do if I was cited for illegal tint?
You can request that the tint be measured with a light meter to verify the VLT percentage. If you have documentation from the shop that installed the tint, bring it to court. You can also contest the citation if you believe the measurement was inaccurate.
