Pennsylvania Window Tint Laws (2026): Legal VLT Limits

Pennsylvania requires front and back side windows on passenger cars to allow at least 70% Visible Light Transmission, effectively matching factory-clear glass and leaving almost no room for aftermarket tinting. Trucks and multipurpose vehicles (SUVs and vans) face no VLT restriction on the windows behind the driver.

What is the legal tint limit in Pennsylvania?

Pennsylvania is among the most restrictive states in the country for window tint. For passenger cars, every side window and the rear window must allow at least 70% VLT. A higher VLT% is lighter; a lower VLT% is darker. Since most factory-installed automotive glass already sits right around the 70% mark, the practical effect is that any additional aftermarket darkening film is off the table for passenger car side and rear windows.

For trucks and multipurpose vehicles (SUVs, vans, and full-size pickups), the 70% rule applies to the front side windows just as it does for sedans. But the windows behind the driver and the rear window face no VLT requirement for trucks and multipurpose vehicles, provided they have the required dual outside mirrors. This is the key exception that gives SUV and truck owners flexibility.

Two details behind that table are easy to miss. First, the pre-1998 passenger car rear window is governed by a labeling rule rather than a percentage: Table X assigns those vehicles a VESC-20 requirement, meaning the material must carry a label, permanently installed between the film and the glazing, containing the manufacturer name or a registration number and the statement "Complies with VESC-20." Second, under 67 Pa. Code 175.264, using a sun screening device requires right and left outside rearview mirrors with a minimum reflective surface of 19.5 square inches each, unless the material is applied only above the AS-1 portion of the windshield.

Pennsylvania's rules are written entirely in terms of light transmittance. Neither 75 Pa.C.S. 4524 nor 67 Pa. Code Chapter 175, including Table X and the PennDOT window tint fact sheet, sets a reflectance limit or separately bans mirrored or metallic film, so a film is judged against the VLT figures above rather than against a reflectivity cap.

Windshield tint rules in Pennsylvania

Pennsylvania permits material along the top edge of the windshield only under the conditions in 67 Pa. Code 175.263(a): the products or materials must be transparent, they must not encroach upon the AS-1 portion of the windshield as provided by FMVSS No. 205, and they must be no more than 3 inches from the top of the windshield. Below that narrow band, the windshield must allow at least 70% VLT.

Because the regulation permits only transparent material at the top edge, a darkening strip is not what the rule describes, even a light one. Spray-on tints and any opaque or colored materials on the windshield below the 3-inch line are not permitted either.

The AS-1 constraint is separate from the 3-inch measurement, and both have to be satisfied. AS-1 refers to the marked portion of the windshield under FMVSS No. 205, and material may not encroach on it. There is also a knock-on requirement worth knowing before you install anything: under 67 Pa. Code 175.264, a vehicle using a sun screening device must have right and left outside rearview mirrors of at least 19.5 square inches of reflective surface each, unless the material is applied only above the AS-1 portion of the windshield.

Medical exemptions

Pennsylvania allows medical exemptions under 75 Pa.C.S. 4524 and 67 Pa. Code 175.265. To obtain one, a licensed physician or optometrist must provide a medical certification of need due to a disability, and PennDOT determines in consultation with its Medical Advisory Board that the use is justified. Conditions commonly raised include lupus and other photosensitivity disorders and post-surgical eye conditions.

One limit catches most applicants by surprise: a Pennsylvania medical exemption does not authorize dark tint. Under 67 Pa. Code 175.265(b)(2), an application for a certificate of exemption "will be granted only for colorless sun screening device or other material," and 175.265(d) describes the certificate as authorizing "a colorless sun screening device or other material which filters ultraviolet light." PennDOT's fact sheet says the same thing: medical exemptions are available for colorless window tint products that filter incoming ultraviolet light. If you are expecting a medical exemption to let you run darker film, it will not.

You apply to PennDOT for the certificate of exemption. Unlike states where you simply keep a doctor's note in the car, Pennsylvania requires an actual state-issued exemption certificate. That certificate must be carried in the vehicle at all times and presented to a law enforcement officer upon request. Without the PennDOT certificate in the vehicle, the material is not protected even if you have a doctor's note.

The exemption is issued for one specific vehicle, not for the person. The application must describe the vehicle by make, year, model and vehicle identification number, and under both 67 Pa. Code 175.265(e) and 75 Pa.C.S. 4524(e)(5) the certificate is void upon the sale or transfer of that vehicle. Before a sale, it is the owner's responsibility to remove any non-complying material, destroy the certificate, and give the buyer a notarized statement identifying the vehicle and the process used to remove the material. Changing vehicles means a fresh application, not a paperwork update.

How tint is measured and certified

VLT is measured with a light-transmission meter that shines a beam through the glass and reads the percentage that passes through. Table X carries a tolerance in its own preamble: "All light transmittance levels listed below assume a 3% accuracy (plus or minus 3%)." A reading a point or two under 70% therefore sits inside the accuracy the regulation itself assumes.

Pennsylvania does not require a compliance sticker on vehicles that do not have special-use or medical exemptions. For vehicles with an exemption, the PennDOT exemption certificate itself serves as the documentation. Standard vehicles with factory-stock glass do not need any paperwork, since factory glass typically meets the 70% standard.

If you are buying a used vehicle, especially a used sedan or wagon, verify the condition of any existing tint. Some prior owners install aftermarket film on passenger cars, not realizing Pennsylvania's restriction is effectively a no-tint rule for those windows. You will be responsible for any non-compliant film on a vehicle you purchase and register in Pennsylvania.

Penalties for illegal tint in Pennsylvania

Section 4524 sets no penalty of its own, so a tint violation falls to the Vehicle Code default. Under 75 Pa.C.S. 6502(a), a person convicted of a summary offense under the Vehicle Code for which no penalty is otherwise provided "shall be sentenced to pay a fine of $25." Figures near $110 that circulate online are the total a defendant pays once court costs and statutory surcharges are added on top, not the statutory fine. The violation carries no jail time, and officers typically issue a citation that can be resolved by paying or contesting it in traffic court.

One appellate decision belongs in any honest description of enforcement here. A roadside tint citation is written under 75 Pa.C.S. 4524(e)(1), which requires only that a person be able to see or view the inside of the vehicle. In Commonwealth v. Brubaker, 5 A.3d 261, 265-66 (Pa. Super. 2010), carried in the Pennsylvania Code's own Notes of Decisions to 67 Pa. Code 175.67, the Superior Court held that the 70% standard in 175.67(d)(4) cannot be incorporated into 4524(e)(1), because 4524(e)(1) requires only that a person be able to see through the windows and does not reference the regulation. A meter reading below 70% is therefore not, on its own, the element the statute a citation is written under makes an officer prove.

Pennsylvania does not have a universal fix-it-ticket program for tint violations. Removing the non-compliant film after a citation will not automatically dismiss the charge, though addressing the problem before a court appearance may be considered in your favor. If you believe your tint is compliant and the officer's reading is incorrect, you can request a meter calibration check and present your own measurement evidence.

Installers who put non-compliant film on Pennsylvania passenger cars expose both themselves and their customers to liability. Because the 70% standard effectively prohibits any visible darkening film on passenger car side and rear windows, reputable installers in Pennsylvania typically decline to apply aftermarket tint to those windows.

If you want to tint your windows in Pennsylvania

If you drive a passenger car (sedan, coupe, wagon, or hatchback), the honest answer is that there is almost nothing you can legally add to your front side windows, back side windows, or rear window. The 70% minimum matches factory glass, so any film that visibly darkens the glass will likely fall below the threshold. Your options for passenger cars are limited to UV-blocking clear films that do not reduce visible light transmission.

If you drive a truck, SUV, or van, you have real options. Your front side windows must still meet the 70% standard, so no dark tint there. But your rear side windows and rear window carry no requirement. You can apply any darkness of film behind the driver, including very dark privacy tints, as long as you have the required right and left outside mirrors. This is the standard setup many Pennsylvania SUV and truck owners use.

If you have a qualifying medical condition, understand what the PennDOT certificate of exemption actually authorizes before you buy film: colorless, ultraviolet-filtering material, not darker tint. Apply before anything is installed, keep in mind that the certificate covers one specific vehicle and goes void if you sell it, and carry the certificate in the vehicle once it is issued.
