In Pennsylvania, window tint laws are in place to ensure road safety, visibility, and clear communication between drivers and law enforcement. However, if you have a medical condition that makes exposure to sunlight or ultraviolet (UV) rays harmful, the state offers a legal pathway to get darker tint through a medical exemption.
But even with this exemption, many residents ask: is there a limit to how dark my tint can be with a medical exemption in Pennsylvania?
Let’s break down exactly what Pennsylvania law says about medical exemptions for window tint, what limitations still apply, and how to stay legal while protecting your health.
Understanding Standard Tint Limits in Pennsylvania
Before diving into medical exemptions, it’s important to understand Pennsylvania’s baseline tint laws. These apply to vehicles that do not have a medical exemption:
- Windshield: Only non-reflective tint is allowed above the AS-1 line or top 3 inches.
- Front Side Windows: Must allow more than 70% of visible light in.
- Back Side Windows: Must also allow more than 70% visible light transmission (VLT) for passenger vehicles. SUVs and vans have more flexibility.
- Rear Window: Same rule—must allow more than 70% of light in unless you are driving a multi-purpose vehicle (MPV) with side mirrors.
Without a medical exemption, any tint darker than these thresholds could result in fines, failed vehicle inspections, or being forced to remove the tint entirely.
What Is a Medical Tint Exemption?
A medical window tint exemption in Pennsylvania allows individuals with qualifying health conditions to legally install window film that exceeds the state’s standard darkness limits.
The exemption is granted based on a prescription or written recommendation from a licensed physician or optometrist. This document must explain:
- The medical necessity for darker tint
- The nature of the condition
- Whether the exemption is permanent or temporary
Pennsylvania does not require residents to file this exemption with the DMV or submit a special form. You simply need to carry the physician’s signed statement in your vehicle at all times to prove your tint is legal.
So, Is There a Limit with a Medical Exemption?
Here’s the key: there is no exact numerical limit defined in Pennsylvania law for how dark your tint can be with a valid medical exemption.
However, this doesn’t mean there are no practical limits.
Because the law does not define a strict percentage (like 20% or 5% VLT), your physician’s discretion plays a critical role. The level of tint you install should be reasonably aligned with the medical condition documented in your exemption note. If your condition calls for maximum UV protection, a much darker tint may be justified.
That said, the tint must still allow for safe operation of the vehicle, and your visibility cannot be reduced to a dangerous level—especially at night. Law enforcement or inspection stations may question your tint if it appears extremely dark and you cannot provide a valid medical certificate.
How Law Enforcement Views Dark Tint with a Medical Exemption
During a traffic stop, if an officer notices your windows are darker than legally permitted, they may pull you over to verify your exemption.
At that point, it is your responsibility to show your signed physician’s statement, which should include:
- The reason you need darker tint
- The condition being treated
- Duration (temporary or permanent)
If you cannot produce this documentation, you may receive a citation—even if you genuinely have a qualifying condition.
If you can produce valid documentation, the officer is required to honor your exemption and allow you to continue without penalty, assuming your tint does not create a visibility hazard.
Can I Go as Dark as 5% or Limo Tint?
Many people ask whether they can go all the way down to 5% VLT (commonly known as limo tint) with a medical tint exemption.
While technically the law doesn’t prohibit it if you have a valid exemption, it is not guaranteed that this level of darkness will be viewed as reasonable by law enforcement or during a vehicle inspection. If your physician states that this level of darkness is required and justifies it in the medical certificate, you’re more likely to be in compliance.
Still, it’s wise to consult your tint installer and medical provider before going to the extreme end of the spectrum. For most individuals with conditions like lupus, photophobia, or other UV-related issues, tints in the 20% to 35% VLT range are typically sufficient for protection without severely compromising visibility.
Does the Type of Tint Matter?
Yes. While VLT percentage is the most visible factor, the type of tint matters too. Many medical exemptions are specifically for UV protection, not necessarily for darker tint.
This is where ceramic window films come into play. These advanced films block up to 99% of UV rays without having to be extremely dark. For some individuals, especially those with eye conditions, ceramic films provide the medical protection they need without overly reducing visible light transmission.
If your goal is to manage a skin or autoimmune condition, you may not need extremely dark film—just one that blocks harmful rays effectively. This can help keep you compliant and safe without sacrificing nighttime visibility.

Choosing the Right Tint Level for Your Medical Condition
