Michigan mainly restricts where film may be placed on front glass. It does not give ordinary full front-side tint a legal VLT percentage.

| Window | Requirement |
|---|---|
| Windshield | Film only along the top edge, no lower than four inches from the top or the shade band, whichever is closer to the top. MCL 257.709(1)(a). |
| Front side | Ordinarily film only along the top four inches of the side windows/sidewings beside the driver or front passenger. No general full-window VLT allowance. |
| Rear side | No numerical VLT minimum. Section 257.709(1)(b) prohibits total solar reflectance of 35% or more. |
| Rear window | No numerical VLT minimum; reflectance must stay below 35%. Use both outside mirrors when rear visibility is obstructed. |
Darkness and reflection are different
Michigan State Police confirms that darkness is not numerically specified. That does not authorize front film below the allowed strip. The statute’s rear-reflectance wording is 35% or more prohibited, so exactly 35% is not a safe stated maximum. It expressly includes silver or gold reflective film.
Medical-necessity letters
A physician or optometrist may determine that special treatment is medically necessary for a light-sensitive or photosensitive person. The owner or operator must possess the signed letter. Treatment must still preserve the driver’s clear view. State Police confirms another person may drive when the statutory conditions are satisfied.
Before you rely on this guide
This is general information, not legal advice, a vehicle inspection, or permission to install a particular film. Exceptions and enforcement procedures can depend on your circumstances.
- No ordinary film certification-label requirement was found in the reviewed tint section.
- Michigan restricts where ordinary front-window film may be placed. A product labeled 35% does not make full-front-window tint lawful.
