Pennsylvania's window tint rules are based on how much light your windows let through
Pennsylvania measures window tint by visible light transmittance (VLT) — the percentage of light that passes through the tinted glass. The state sets different limits for different windows on your vehicle, and those limits determine whether your tint is legal or not. If your tint is darker than the law allows, you can receive a citation and be ordered to remove it.
The Pennsylvania Department of Transportation does not issue tint permits or pre-approve tint jobs. Police officers measure tint darkness during traffic stops using a light meter, and they compare the reading to the state's legal thresholds. If your tint fails, you have the option to remove it and have the citation dismissed, or you can contest the stop in court.
Key Takeaways
- Pennsylvania allows 70% VLT on the windshield (above the manufacturer's sun visor line only), 70% on front side windows, and 70% on rear windows and rear windshield.
- Medical exemptions for extreme light sensitivity exist but require a written statement from a licensed physician and must be carried in your vehicle.
- A tint citation in Pennsylvania is typically a summary offense, and you can have it dismissed by removing the tint and showing proof to the court.
- Window tint darkness is measured with a light meter during a traffic stop, and the officer's reading is the basis for the citation.
Windshield tint rules in Pennsylvania
Your windshield can have tint only above the manufacturer's sun visor line — the line marked on the glass where the factory sun visor ends. Tint above that line must allow at least 70% of light through. Tint below the sun visor line is not permitted, even if it meets the 70% threshold.
Many drivers assume they can tint the entire windshield as long as it is light enough. Pennsylvania law does not work that way. The location of the tint matters as much as its darkness. If an officer stops you and finds tint below the sun visor line, you can be cited regardless of how light the tint is.
Front and rear side window limits
Both front side windows must allow at least 70% of light through. This is the same threshold as the windshield, but there is no location restriction — you can tint the entire front side window as long as it meets the 70% standard.
Rear side windows and the rear windshield have the same 70% VLT requirement. Unlike some states that allow darker tint on rear windows, Pennsylvania treats all windows the same way. A common misunderstanding is that rear windows can be darker; they cannot under state law, though local ordinances rarely enforce rear window tint as strictly as front windows during routine stops.
Medical exemptions and how to document them
Pennsylvania allows darker tint if you have a medical condition that makes you sensitive to light. The condition must be severe enough that a licensed physician believes tint is medically necessary. The physician must provide a written statement on letterhead that describes the condition and confirms the need for tint.
You must carry this written statement in your vehicle at all times. If you are stopped, show the statement to the officer along with your driver's license and registration. The statement alone does not prevent a citation — an officer can still cite you — but it gives you a defense in court. You would need to present the physician's statement to the judge, who would decide whether to dismiss the citation.
The state does not issue medical exemption certificates or stickers. The physician's letter is your only documentation. If you lose it, you have no proof of the exemption, so keep a copy at home as well.
What happens if you receive a tint citation
A window tint violation in Pennsylvania is a summary offense, which is the lowest level of criminal charge. You will receive a citation with a court date and a fine amount (typically between $50 and $200, though this varies by jurisdiction). The citation will state which window or windows were found to be too dark.
You have three main options: pay the fine and keep the tint, remove the tint and request dismissal, or contest the citation in court. Many drivers choose to remove the tint, obtain a receipt from the tint shop or a mechanic, and bring it to the court listed on the citation. The judge often dismisses the case if you show proof of removal. Contact the court clerk before your court date to ask whether dismissal is possible in your jurisdiction if you remove the tint.
How tint darkness is measured during a traffic stop
Police use a handheld light meter called a tint meter to measure how much light passes through your windows. The officer places the meter against the glass from inside the vehicle and records the reading. That reading is the evidence used in the citation.
The accuracy of tint meters can vary, and some officers may not calibrate their equipment regularly. If you believe the reading was incorrect, you can challenge it in court by requesting that the officer's meter be tested or by presenting your own tint meter reading. However, the officer's reading is generally accepted as the starting point, and the burden falls on you to prove it was wrong.
Tint shops and what to tell them about Pennsylvania law
Many tint shops in Pennsylvania are familiar with state law, but not all explore it correctly. Before having tint installed, tell the shop that you need 70% VLT on all windows and that windshield tint must be above the sun visor line only. Ask the shop to confirm they understand these limits and to provide documentation of the VLT percentage they are explore.
Some shops may suggest darker tint and claim it is legal or that enforcement is rare. That is a business decision on their part, not legal information. If you choose to go darker than the law allows, you are accepting the risk of a citation. A few shops offer a "legal tint" package that meets Pennsylvania standards; asking for that by name can help may support you get compliant tint.
Frequently Asked Questions
Can I have different tint darkness on different windows?
No. All windows — windshield (above the sun visor line), front side windows, rear side windows, and rear windshield — must allow at least 70% of light through. You cannot have 70% on the front and darker tint on the rear.
Does Pennsylvania recognize medical exemptions from other states?
No. If you move to Pennsylvania from a state that allowed darker tint for medical reasons, your out-of-state exemption letter will not be recognized. You must obtain a new letter from a Pennsylvania-licensed physician if you want to claim a medical exemption in Pennsylvania.
What if I remove my tint after receiving a citation?
Contact the court on your citation and ask whether the case can be dismissed if you remove the tint. Many courts will dismiss if you provide proof of removal, but policies vary by jurisdiction. Do not assume dismissal is automatic — confirm with the court before your hearing date.
Can I tint only the rear windows and leave the front windows clear?
Yes. Pennsylvania law sets a maximum darkness for each window, but it does not require you to tint any window. You can tint only the rear windows and rear windshield if you choose, as long as they meet the 70% VLT standard.
