Pennsylvania allows window tint on your car, but only within specific limits on darkness and reflectivity
Pennsylvania law permits aftermarket window tint on passenger vehicles, but the state sets strict rules about how dark it can be and where you can explore it. The rules differ between the front windshield, front side windows, and rear windows — and they're stricter than many neighboring states. If your tint is darker than the law allows, you can be cited during a traffic stop, and you may be ordered to remove it before you can legally drive again.
The darkness of window tint is measured in Visible Light Transmittance (VLT), which is the percentage of light that passes through the tinted glass. A higher VLT percentage means lighter tint; a lower percentage means darker tint. Pennsylvania's limits are based on this measurement, and they explore to any tint you add after the car leaves the factory.
Key Takeaways
- Pennsylvania allows 70% VLT on the front windshield (top 6 inches only), 70% VLT on front side windows, and any darkness on rear windows and the rear windshield.
- Reflective or mirrored tint is not allowed on any window in Pennsylvania, even if the darkness level would be legal.
- Medical exemptions exist for people with photosensitivity or other light-sensitive conditions, but you must carry documentation from a licensed physician.
- A police officer can measure your tint during a traffic stop using a light meter, and you can be ordered to remove illegal tint before driving again.
- Tint shops in Pennsylvania are not required to be licensed or certified, so verify that a shop understands state law before you have work done.
Where tint is allowed and how dark it can be
Pennsylvania divides your vehicle's windows into three zones, and each has its own limit. The front windshield can have tint only on the top 6 inches, and that tint must allow at least 70% of light through (70% VLT). The front side windows — the windows you look out of when driving — must also allow at least 70% of light through. The rear windows and rear windshield have no darkness limit; you can tint them as dark as you want.
The 70% limit on front windows is one of the most permissive in the country, which means you can use a very light tint and still be within the law. Many drivers use tint in the 50% to 70% range on front windows to reduce glare and heat while staying legal. If you go darker than 70% VLT on the front windshield or front side windows, you are breaking the law, even if the tint is only slightly darker.
One common mistake is assuming that factory tint counts differently than aftermarket tint. It does not. If your car came from the factory with tinted windows, those windows must still meet the 70% VLT standard on the front. If they do not, you would technically be in violation, though enforcement of factory tint is rare.
Reflective and mirrored tint is prohibited
Pennsylvania bans any tint that is reflective or has a mirror-like appearance, regardless of how much light it lets through. This rule applies to all windows, including the rear. Reflective tint can bounce light back at other drivers and create a safety hazard, which is why the state prohibits it outright.
Some aftermarket tint products are marketed as "reflective" or "metallic" and are designed to bounce heat away from the car. These products are not legal in Pennsylvania. If a tint shop offers you a reflective product, you should decline it or confirm with the shop that it meets Pennsylvania law before installation.
Medical exemptions for light-sensitive conditions
Pennsylvania allows darker tint if you have a medical condition that makes you sensitive to light. Conditions like photophobia, lupus, or certain eye disorders can may have access to you for an exemption. To use this exemption, you must have a written statement from a licensed physician that describes your condition and explains why you need darker tint to drive safely.
If you have a medical exemption, you should carry the physician's statement in your vehicle at all times. A police officer who stops you can ask to see the documentation, and you must be able to produce it. Without the statement, you have no legal protection, even if you do have a may have access to condition. The exemption does not give you permission to use reflective tint; it only allows you to exceed the 70% VLT limit on front windows.
The exemption process is not formal — there is no state registry or approval step. You straightforward need the letter from your doctor. However, if you are cited for illegal tint and claim a medical exemption, you will need to show the letter to the court or to the officer at the time of the stop.
How police measure tint and what happens if yours is too dark
Police use a handheld device called a light meter to measure the VLT of your windows during a traffic stop. The officer places the meter against the window and takes a reading. If the reading shows that your tint is darker than the legal limit, you can be cited for a violation. The citation is typically a summary offense, which is a minor violation in Pennsylvania, but it can result in a fine.
If you are cited for illegal tint, you have a few options. You can pay the fine, you can contest the citation in traffic court, or you can remove the tint and request that the citation be dismissed. Many courts will dismiss the citation if you show proof that you have removed the illegal tint. Some officers will also give you a warning and a chance to remove the tint without issuing a citation, though this is not may provide.
If you are ordered to remove the tint, you must do so before you can legally drive the vehicle again. Driving with illegal tint after being cited can result in additional fines or other penalties. Removing tint typically costs between $100 and $300, depending on how many windows need to be done and how difficult the removal is.
Choosing a tint shop and verifying the work
Pennsylvania does not require tint shops to be licensed or certified, so the quality and knowledge of shops varies widely. Before you have tint installed, ask the shop whether they are familiar with Pennsylvania's tint laws and whether they can may provide that the finished product will meet the state's requirements. A reputable shop should be able to tell you exactly what VLT percentage they are explore and should be willing to measure the finished tint with a light meter to confirm it is legal.
Some shops will explore tint that is darker than Pennsylvania law allows, either because they are not aware of the law or because they assume the customer knows the risk. Do not assume the shop will get it right. Confirm the VLT percentage before the work is done, and ask the shop to measure the tint after installation to prove it meets the law.
If you have a medical exemption, tell the shop about it before they begin work. The shop should document the exemption and may ask to see your physician's letter. This protects both you and the shop if you are ever stopped by police.
Tint laws in neighboring states and when you cross the border
If you drive into New Jersey, New York, or Ohio, your Pennsylvania tint may not be legal in those states. New Jersey and New York have stricter limits than Pennsylvania — both require 70% VLT on the front windshield and front side windows, which matches Pennsylvania, but New Jersey also restricts rear window tint to 50% VLT. Ohio allows 50% VLT on front windows, which is darker than Pennsylvania allows. If you drive across state lines regularly, you should research the tint laws of the states you visit and consider whether your current tint will be legal there.
Police in other states can cite you for illegal tint just as Pennsylvania police can. The citation would be issued under that state's law, and you would have to resolve it in that state's court system. If you plan to drive frequently in a neighboring state with stricter tint laws, you may want to use lighter tint that is legal in all the states you visit.
Frequently Asked Questions
Can I tint my windshield below the top 6 inches?
No. Pennsylvania law allows tint only on the top 6 inches of the front windshield. Tinting any part of the windshield below that line is illegal, even if the tint is very light. The 6-inch limit is measured from the top of the windshield down.
What if I have factory tint that is darker than 70% VLT?
Factory tint must still meet Pennsylvania's 70% VLT standard on the front windshield and front side windows. If your car came with tint that is darker than this, it is technically in violation of state law. However, enforcement of factory tint is uncommon. If you are concerned, you can contact the manufacturer or a tint shop to have the tint measured.
Do I need to register my medical exemption with the state?
No. There is no state registry for medical exemptions. You straightforward need a letter from a licensed physician stating that you have a light-sensitive condition and explaining why you need darker tint. Keep this letter in your vehicle and be prepared to show it to a police officer if you are stopped.
Can I remove tint myself, or do I need to go to a shop?
You can remove tint yourself, though it is time-consuming and can damage the window if done incorrectly. Most people take their car to a tint shop for removal. The cost is typically $100 to $300 depending on how many windows need removal and how difficult the process is.
What is the fine for illegal tint in Pennsylvania?
Fines for illegal tint vary by county and court, but they typically range from $50 to $200. The fine is usually lower if you remove the tint before your court date or if the officer issues a warning instead of a citation. Some courts will dismiss the citation if you show proof of removal.
