Michigan Window Tint Law 2026
Michigan publishes no visible-light-transmittance percentage we have been able to establish for an ordinary passenger car, so this page shows what its law does say and marks the missing figures as gaps rather than guessing at them.
The limits at a glance
Michigan sets the same limits for passenger cars and for SUVs, vans and trucks, so there is nothing to switch between.
This state regulates this glass in words rather than a percentage. There is no figure to filter film against, and we will not translate a written standard into a number.
Every Michigan tint rule we track
| Rule | Applies to | What the law says | Source |
|---|---|---|---|
| Windshield strip — how dark the strip may be | All vehicles | No VLT figure for the permitted top-edge band; the statute regulates its extent, not its darkness. | MCL 257.709(1)(a) — Michigan Compiled Laws · read “a tinted film may be used along the top edge of the windshield” |
| Windshield strip — how far down it may extend | All vehicles | 4 inDetailTwo constraints with the restrictive tie-breaker ("whichever is closer to the top"): 4 inches from the top, or the factory shade band. The same clause governs the permitted band on the front side windows. | MCL 257.709(1)(a) — Michigan Compiled Laws · read “if the material does not extend more than 4 inches from the top of the windshield, or lower than the shade band, whichever is closer to the top of the windshield” |
| Windshield below the strip | All vehicles | unclear No published figure Under review — this dimension is still under review. This is a gap in our research, and it says nothing about what Michigan requires here; the state may set its rule in words rather than a percentage. | — |
| Front side windows | All vehicles | No VLT percentage exists in Michigan law. The rule is positional: tinted film on the front side windows and sidewings is permitted ONLY along the top edge, within 4 inches of the top of the windshield or the shade band, whichever is closer to the top. Below that band, film is prohibited at any darkness.DetailDeliberately NOT encoded as a number. Publishing any Michigan front-side VLT figure would attribute to the statute a rule it does not contain — and would tell a reader that some darkness is lawful on the front doors when none is. The 4-inch band is shared with the windshield rule in the same clause. | MCL 257.709(1)(a) — Michigan Compiled Laws · read “except that a tinted film may be used along the top edge of the windshield and the side windows or sidewings immediately adjacent to the driver or front passenger if the material does not extend more than 4 inches from the top of the windshield, or lower than the shade band, whichever is closer to the top of the windshield” |
| Back side windows | All vehicles | confirmed No VLT limit. Nonreflective smoked or tinted glass, nonreflective film, a perforated window screen, or other decorative window application may be used on a side window to the rear of the driver.DetailAffirmative absence: subsection (3) lists what the section does not apply to, and this is one of the listed items. Behind the driver, Michigan constrains reflectance only. | MCL 257.709(3)(b) — Michigan Compiled Laws · read “The use of a nonreflective, smoked or tinted glass, nonreflective film, perforated window screen, or other decorative window application on the rear window or a side window to the rear of the driver.” |
| Rear window | All vehicles | confirmed No VLT limit on the rear window. Draperies, louvers and other special window treatments are also permitted there where the vehicle has two outside rearview mirrors, one per side, giving a clear view of the highway behind. Two outside rearview mirrors required where rear visibility is obstructed. | MCL 257.709(3)(a) — Michigan Compiled Laws · read “The use of draperies, louvers, or other special window treatments, except those specifically designated in this section, on the rear window, or a side window to the rear of the driver if the vehicle is equipped with 2 outside rearview mirrors, 1 on each side, adjusted so that the driver has a clear view of the highway behind the vehicle.” |
| Reflectivity — front side windows | All vehicles | Reflective film is prohibited outright on the front windshield, the side windows immediately adjacent to the driver or front passenger, and the forward sidewings — no permitted percentage.DetailThe front prohibition reaches reflective AND nonreflective film alike, subject only to the 4-inch top band. | MCL 257.709(1)(a) — Michigan Compiled Laws · read “A sign, poster, nontransparent material, window application, reflective film, or nonreflective film upon or in the front windshield, the side windows immediately adjacent to the driver or front passenger, or the sidewings adjacent to and forward of the driver or front passenger” |
| Reflectivity — back side windows | All vehicles | 35% reflectance maximumDetailExpressed as TOTAL SOLAR REFLECTANCE in the visible light range, and the statute names silver and gold reflective film specifically. This 35% figure is the only percentage in MCL 257.709 — it is a reflectance cap, not a VLT limit, and must never be rendered as one. | MCL 257.709(1)(b) — Michigan Compiled Laws · read “A rear window or side window to the rear of the driver composed of, covered by, or treated with a material that creates a total solar reflectance of 35% or more in the visible light range, including a silver or gold reflective film.” |
| Medical exemption | All vehicles | RequiredDetailCarried letter from a physician or optometrist; no state permit. | MCL 257.709(3)(e) — Michigan Compiled Laws · read “A special window treatment or application determined necessary by a physician or optometrist, for the protection of a person who is light sensitive or photosensitive, if the owner or operator of a motor vehicle has in possession a letter signed by a physician or optometrist, indicating that the special window treatment or application is a medical necessity.” |
| Certification sticker / label | All vehicles | No compliance sticker is required. The section expressly permits placement of a necessary certificate or sticker so long as it does not obstruct the driver’s clear view. | MCL 257.709(3)(c) — Michigan Compiled Laws · read “The placement of a necessary certificate or sticker that does not obstruct the driver's clear view of the roadway or an intersecting roadway.” |
| Restricted colors | All vehicles | No colour list for darkness, but silver and gold reflective films are named within the 35% total-solar-reflectance prohibition for rear glass. | |
| Side mirrors required if the rear window is tinted | All vehicles | Required Required where driver visibility through the rear window is obstructed. | MCL 257.709(2) — Michigan Compiled Laws · read “A person shall not drive a motor vehicle if driver visibility through the rear window is obstructed, unless the vehicle is equipped with 2 rearview mirrors, 1 on each side, adjusted so that the operator has a clear view of the highway behind the vehicle.” |
This state publishes no light-transmittance figure for this glass, so there is no percentage to match a film against. Other rules — colour, reflectivity, obstruction — can still apply, so we are not going to present a shelf as though nothing does.
