Understanding Pennsylvania Window Tint Law

When it comes to window tinting for vehicles, it’s important to understand the laws and regulations that govern it. In Pennsylvania, there are specific guidelines that dictate how dark you can tint your car windows. By following these regulations, you can ensure that you are driving within the legal limits and avoid any potential fines or penalties.

What is the Pennsylvania Window Tint Law?

The Pennsylvania window tint law sets limits on the darkness of tinting for various windows on a vehicle. These limits are measured by the Visible Light Transmission (VLT) percentage, which refers to the amount of light that can pass through the window. The lower the VLT percentage, the darker the window tint.

According to the Pennsylvania law, the front windshield must allow at least 70% of light to pass through. This means that only a minimal tint strip, commonly known as an “eyebrow,” is allowed at the top of the windshield. The tint on the front side windows must have a VLT percentage of 70% or higher as well.

However, the rear side windows and the rear window can have a darker tint. The law allows for a VLT percentage of 70% or higher on these windows. This means that you can have a darker tint on the back of your vehicle, as long as it complies with the minimum VLT requirement.

Why Does Pennsylvania Have Window Tint Laws?

The purpose of window tint laws is to ensure the safety of both drivers and law enforcement officers. Excessively dark window tint can obstruct the driver’s view, especially at night or in adverse weather conditions. It can also make it difficult for law enforcement officers to see inside the vehicle, which can raise concerns about public safety.

By setting specific guidelines for window tinting, Pennsylvania aims to strike a balance between allowing drivers to personalize their vehicles and maintaining safety on the roads.

Consequences of Violating the Window Tint Law

If you violate the Pennsylvania window tint law, you may face consequences such as fines or even having your vehicle inspected or impounded. The exact penalties can vary depending on the severity of the violation and the discretion of the law enforcement officer.

It’s important to note that ignorance of the law is not a valid defense. As a vehicle owner, it is your responsibility to ensure that your window tint complies with the regulations set forth by the state.

Exceptions to the Window Tint Law

There are a few exceptions to the Pennsylvania window tint law. Vehicles that are used for medical reasons, such as those transporting individuals with light-sensitive conditions, may be granted an exemption. However, this exemption requires proper documentation and approval from the Pennsylvania Department of Transportation.

Additionally, vehicles that were manufactured with tinted windows are also exempt from the law. These vehicles typically have a factory-installed tint that meets the required VLT percentage.


Understanding the Pennsylvania window tint law is essential for all vehicle owners in the state. By following the guidelines and ensuring that your window tint complies with the VLT percentage requirements, you can avoid any legal issues and drive safely on the roads.

Remember, it’s always a good idea to consult with a professional window tinting service to ensure that your tint is within the legal limits and meets all necessary requirements. Stay informed and drive responsibly!
