Michigan Tint Limits at a Glance
Under MCL §257.709, Michigan prohibits ANY aftermarket tint on front side windows. Back and rear windows can be any darkness for all vehicle types.
| Window | Sedan | SUV / Van / Truck |
|---|---|---|
| Front Windshield | Top 4 inches only, must not exceed 35% light reflectance | Top 4 inches only, must not exceed 35% light reflectance |
| Front Side Windows | No aftermarket tint allowed | No aftermarket tint allowed |
| Back Side Windows | Any darkness | Any darkness |
| Rear Window | Any darkness | Any darkness |
| Max Reflectivity | 35% light reflectance maximum | 35% light reflectance maximum |
Michigan's front-window ban is among the strictest in the US. A medical exemption under MCL §257.709(3) is the only way to legally tint front side windows.
How Michigan Compares to Neighboring States
| State | Front Side | Back Side | Rear |
|---|---|---|---|
| Michigan | No tint | Any | Any |
| Ohio | 50% | Any | Any |
| Indiana | 30% | 30% | 30% |
| Wisconsin | 50% | 35% | 35% |
| Illinois | 35% | 35% | 35% |
Michigan is uniquely strict on front windows but lenient on rear windows. Drivers crossing from Ohio or Indiana with tinted front windows are immediately in violation.
No Annual Inspection — Traffic Stops Are the Only Risk
Unlike states such as New York or Texas, Michigan has no annual vehicle safety inspection. Tint enforcement happens exclusively at traffic stops. Michigan State Police (MSP), Detroit Police (DPD), Grand Rapids Police (GRPD), and local agencies enforce tint laws using handheld tint meters.
High-enforcement corridors: I-75 (Detroit to Flint), I-94 (Detroit to Ann Arbor), I-96 (Detroit to Grand Rapids/Lansing), M-10 (Lodge Freeway in Detroit), and US-131 (Grand Rapids). MSP regularly runs enforcement campaigns on these corridors.
Penalties for Illegal Tint in Michigan
A $225 medical exemption costs less than two tint tickets and protects you permanently.
Medical Exemptions Under MCL §257.709(3)
Michigan law allows individuals with qualifying medical conditions to obtain a physician-certified exemption permitting aftermarket tint on front side windows. This is authorized under MCL §257.709(3). No Secretary of State (SOS) filing is required — it is a physician-issued certification.
