Windshield Tint Strips and Wisconsin Law

Windshield tint strips can help reduce glare, block harsh sunlight, and make driving more comfortable for those with medical conditions. Wisconsin law is strict when it comes to how much tint you can legally use and where you can use it. This guide covers what you can and can’t do with a windshield tint strip, the state’s legal tint limits, and how to get a medical exemption if you need extra protection due to a health issue.

Wisconsin’s Window Tint Laws: The Basics

Wisconsin has clear rules about how dark your window tint can be. These rules are enforced by law enforcement and are designed to balance driver comfort with safety.

• Front side windows: Must allow at least 50% of light in (50% VLT)
• Back side windows: Can be as dark as 35% VLT
• Rear window: Must also allow at least 35% VLT
• Windshield: Only non-reflective tint is allowed, and it must be above the AS-1 line

The AS-1 line is a mark found on most windshields, usually about five or six inches from the top. Any tint below this line is illegal, unless you have a medical exemption.

What Is a Windshield Tint Strip?

A windshield tint strip is a band of tint running along the top of the windshield. Its main purpose is to cut down on glare from the sun and headlights. While many drivers like the look and function of a tint strip, Wisconsin law only allows non-reflective tint above the AS-1 line. Anything darker below that line can get you a ticket.

If you are stopped with illegal tint, the typical fine in Wisconsin is $175. Repeat violations can lead to more headaches and hassle.

When Medical Needs Make a Difference

Some people are especially sensitive to sunlight because of medical conditions. For them, the standard tint allowance is not enough. That’s why Wisconsin law allows medical exemptions for darker window tint, including windshield tint strips below the AS-1 line.

Qualifying Medical Conditions

Medical exemptions are available for a range of conditions, such as:

• Photophobia (light sensitivity)
• Lupus
• Chronic migraines
• Macular degeneration
• Albinism
• Porphyria
• And others listed on the All qualifying conditions page

If you have one of these or a similar condition, you may qualify for a medical exemption in Wisconsin.

How to Get a Medical Exemption for Window Tint in Wisconsin

The state does not make exemptions automatic. You need a formal evaluation by a licensed physician, who must document the medical need for extra tint. Here’s how the process works:

1. Book a telemedicine consultation: Connect with a licensed physician through a secure online visit. This service costs $225, which includes your evaluation and signed documentation. If you don’t qualify, you get your money back.
2. Medical review: The doctor will assess your health history and symptoms to determine if extra tint is medically necessary. They may ask about your condition, how sunlight affects you, and your driving habits.
3. Documentation: If approved, you’ll get signed paperwork stating your need for a window tint exemption. Wisconsin requires you to keep this documentation in your vehicle at all times.

What to Expect After Getting an Exemption

Your tint exemption lasts as long as your physician recommends. This could be a year, a few years, or longer, depending on your medical needs. Keep the paperwork in your glove box. If you are stopped, you must show it to law enforcement. Without the document, you could still get a ticket for illegal tint.

Some officers may not be familiar with all the qualifying conditions, so having clear and current documentation is important. If your health changes, or your physician’s recommendation expires, you’ll need to update your exemption.

Common Conditions That May Qualify

Here are some of the most common reasons Wisconsin drivers seek a window tint medical exemption:

• Photophobia: Extreme sensitivity to light, which can make driving painful or dangerous
• Lupus: Sunlight can trigger flare-ups and worsen symptoms
• Migraines: Bright sunlight is a major trigger for some sufferers
• Macular degeneration: Eye disease that can worsen with UV exposure
• Albinism: Lack of pigmentation means less natural UV protection

Wisconsin Law Enforcement and Window Tint Checks

Police and state troopers use portable meters to check window tint levels during traffic stops or routine safety checks. If your tint is darker than the legal limit and you do not have an exemption with you, you can be ticketed. The fine for illegal window tint in Wisconsin is usually $175. Don’t rely on verbal permission or outdated paperwork. Only a current, signed physician exemption will protect you.
