Michigan regulates window tint through MCL 257.709. Below: the minimum visible light transmission (VLT) for each window, the windshield rule, what counts as too reflective, who can get a medical exemption, and how an officer checks a car at the roadside.
Legal tint limits in Michigan
- Front side windows: no aftermarket film allowed.
- Back side windows: any darkness.
- Rear window: any darkness.
Front door windows take no film at all in Michigan; the percentages that matter are the ones behind the driver.
VLT is measured through film and glass together. Factory glass already blocks some light, usually landing between 70% and 80% VLT before any film, so a roll sold as "35%" on a window that started at 75% ends up darker than 35% once installed. Officers meter the finished window, not the box the film came in.
Windshield
Tint only within the top 4 inches or above the factory shade band, whichever is closer to the top; the same band rule applies to the front door windows.
Federal standard FMVSS 205 sets the baseline for the glass itself: the windshield and front side windows of a new car must transmit at least 70% of visible light. State law decides what film may be added afterwards, which is why the windshield rule is usually a strip above the AS-1 line rather than a percentage.
Reflective and colored film
Film behind the driver may not reflect 35% or more of visible light; silver or gold mirrored film is named as prohibited. Film colors not permitted: silver or gold reflective film.
Medical exemptions
Michigan allows darker tint with a medical exemption. A signed letter from a physician or optometrist stating medical necessity is the exemption; no state permit or sticker exists, so keep the letter in the vehicle.
Stickers, mirrors and enforcement
No sticker or certificate is required for legal tint. If the rear window is tinted, the car must have outside mirrors on both sides. Civil infraction with a fine set by the district court (MCL 257.683(6), applied to 257.709).
In practice
Michigan bans film on the windshield and front door windows except a 4-inch band at the top. Windows behind the driver may be any darkness as long as they are not mirrored and two outside mirrors are fitted when the rear view is blocked. Front-window tint is the usual citation and is handled as a civil infraction. Out-of-state registered vehicles are exempt.

What we don't publish
No reviews, no star ratings, no "best installer" lists. Prices on shop profiles are entered by the owner and checked for format, not negotiated or verified by us; where a shop lists nothing, we say "Quote on request" rather than fill the gap. What a person at Armor Atlas does verify is that the shop exists, installs the service and answers the phone — and that check is dated on every listing.
