Michigan Window Tint Laws: What's Allowed on Each Window

What are the window tint laws in Michigan?

Michigan's window tint law is MCL 257.709, and it covers where film can go and how reflective it can be rather than how dark it can be. In front, tinted film is limited to a strip along the top edge; behind the driver, the statute exempts nonreflective smoked or tinted glass and nonreflective film. It sets no darkness percentage.

The statute's only figures for window film are the 4-inch limit in front and the 35% reflectance limit behind the driver, and neither is a darkness percentage. The section is short, and you can read it yourself on the Legislature's website. If you're pricing a job, our window tint cost guide explains how these rules shape a quote.

Can you tint your windshield and front windows in Michigan?

Yes, along the top edge. MCL 257.709 allows a strip of tinted film along the top of the windshield and of the front driver and passenger windows, no more than 4 inches from the top of the windshield or lower than the shade band, whichever is closer to the top.

Below that strip, the statute doesn't allow film on those windows, whether the film is reflective or nonreflective. The one exception that isn't tied to a particular window is the medical exemption, covered below. Our window tinting page covers the two films we install.

Can you tint your back windows and rear window in Michigan?

Yes. MCL 257.709 exempts nonreflective smoked or tinted glass and nonreflective film on a side window to the rear of the driver and on the rear window. The one limit it sets there is on reflectance: material with a total solar reflectance of 35% or more in the visible light range is barred, including silver or gold reflective film.

That makes the back of the vehicle the part of the statute with the most room, and it's where choices about shade, heat and privacy mostly happen. Our carbon vs ceramic tint guide compares the two films we install. Separately, the statute bars driving with the driver's view through the rear window obstructed unless the vehicle has two rearview mirrors, one on each side, adjusted for a clear view of the highway behind.

What is the darkest legal tint in Michigan?

Michigan's statute doesn't name a darkest legal tint, because it sets no darkness percentage for any window. The only percentage it gives for window film is a total solar reflectance of 35% or more behind the driver, and that measures how mirror-like a film is, not how dark it is.

Darkness is usually described as visible light transmission, the share of light a window lets through. MCL 257.709 doesn't use that measure. It decides where film can go and how reflective it can be, which is why this guide is organized by window instead of by percentage.

When you choose a shade, you're choosing for heat, glare, privacy and looks. Ceramic is our premium film and the one we recommend for most drivers, because it reduces interior heat, and carbon is the other film we install. We go over what's allowed on your vehicle when you choose your film.

Can I have 5% tint in Michigan?

Michigan's statute doesn't mention 5% or any other darkness percentage, so the same rules apply to every shade: where the film goes and how reflective it is. In front, only a top-edge strip is allowed, and behind the driver the statute exempts nonreflective film and bars material with a total solar reflectance of 35% or more.

Shade names such as 5% or 35% describe how much light a film lets through, and the statute doesn't use that language. The 35% in MCL 257.709 is reflectance, which is easy to mix up with a 35% darkness level. If you have a specific shade in mind, tell us the vehicle and which windows you'd like to tint, and we go over what's allowed on it when you choose your film.

How do you get a medical window tint exemption in Michigan?

Michigan's statute allows a special window treatment when a physician or optometrist has determined it is necessary to protect a light-sensitive or photosensitive person. The owner or operator needs to have in their possession a letter signed by the physician or optometrist stating that it is a medical necessity, and the treatment can't obstruct the driver's clear vision of the highway or an intersecting highway.

Start with your physician or optometrist, who decides whether the treatment is necessary for you. If you think you may qualify, mention it when you book, and we'll go over film options for your vehicle.

Do Michigan's tint laws apply to out-of-state vehicles?

MCL 257.709 exempts a vehicle registered in another state, territory, commonwealth of the United States, or another country or province. A vehicle registered in Michigan isn't covered by that exemption, so the rules in this guide apply to it.

If you're about to register a vehicle in Michigan, it's worth checking its tint against the windows above first.

Have Michigan's window tint laws changed in 2026?

The version of MCL 257.709 on the Michigan Legislature's website on October 14, 2026 lists 2010 Act 258, effective December 14, 2010, as its most recent amendment.

Laws can change, so the Legislature's page is the place to confirm the current text. This guide was last checked against it on October 14, 2026.

How do you choose legal tint for your car in Michigan?

Start with the windows, then pick the film. Confirm which windows the statute lets you tint, ask whether the film is nonreflective, and ask which windows each quote covers.

• Which windows does this quote cover? In Michigan that means the top-edge strip in front and the rear side windows and rear window behind the driver.
• Is the film nonreflective? Total solar reflectance of 35% or more is the statute's limit behind the driver.
• Is the installer authorized by the film's manufacturer? Elite Auto Lab is a manufacturer-authorized installer.
• What does the warranty cover? A manufacturer can treat an installation that doesn't follow state law as misuse, so ask how a shop's film is covered.

Elite Auto Lab installs only carbon and ceramic film at our Madison Heights shop, which also serves Detroit and Warren drivers, and we go over what's allowed on your vehicle when you choose your film. To compare prices, see our window tint cost guide.

Do Michigan's tint laws affect my window tint warranty?

They can. Our film's manufacturer treats an installation that violates state law as misuse under its warranty, so a job that follows MCL 257.709 also keeps your coverage in place.

Our window tint is backed by the manufacturer's lifetime limited warranty, for as long as the original customer owns the vehicle. Our Detroit window tint page lists what the warranty covers.
