Michigan's window tint rules depend on which windows you're tinting and how dark you go

Michigan law sets different darkness limits for different windows on your vehicle. The darkness of tint is measured in visible light transmission (VLT), which is the percentage of light that passes through the tinted glass. A lower VLT percentage means darker tint. You can tint your windows darker on some parts of your car than others, and the state allows some tint on all windows — but there are hard limits.

The rules are enforced by police during traffic stops, and violations can result in a ticket. The good news is that Michigan's tint laws are less restrictive than many states, so you have room to customize your windows while staying legal.

Key Takeaways

  • Front side windows must allow at least 50% of light through (50% VLT or lighter), and the windshield can only be tinted along the top visor strip.
  • Rear and back side windows can be any darkness, including completely opaque, with no VLT minimum.
  • Tint darkness is measured by a device called a tint meter, which police can use to check your windows during a stop.
  • Medical exemptions exist for people whose skin conditions require protection from sunlight, but you must carry documentation in your vehicle.
  • A tint violation is a civil infraction that can result in a fine; you can remove the tint and have the ticket dismissed in some cases.

Front windshield and front side window rules

Your front windshield can have tint only in a band along the top, typically called the visor strip. This strip cannot extend more than a few inches down from the top of the windshield — the exact measurement is the manufacturer's sun visor line or 5 inches from the top, whichever is smaller. The rest of the windshield must remain clear.

Your front side windows (the windows next to the driver and front passenger) must allow at least 50% of light through. This means you can tint them, but not very dark. A 50% VLT tint is noticeably darker than untinted glass but still allows you to see clearly through the window from outside. If you go darker than 50% on your front side windows, you are breaking the law.

Rear and back side window rules

Michigan places no darkness limit on your rear window or your back side windows (behind the rear doors). You can tint these windows as dark as you want, including complete blackout tint. This is one of the more permissive parts of Michigan's tint law and gives you significant freedom to customize the back of your vehicle.

The only requirement is that your vehicle must have at least one side mirror on each side if your rear window is tinted so dark that you cannot see out of it. This is a safety rule, not a tint rule — it ensures you can still see behind you while driving. Most vehicles already meet this requirement.

How tint darkness is measured and enforced

Police use a handheld device called a tint meter to measure how much light passes through your windows. The meter gives a reading in VLT percentage. If your front side windows read below 50% VLT, you are in violation. The officer will note the reading on the ticket.

You may be stopped specifically for tint, or an officer may check your tint during a traffic stop for another reason. If you receive a ticket, the citation will state which window was too dark and what the meter reading was. You can contest the ticket in court if you believe the reading was inaccurate, though this is uncommon.

Medical exemptions for sun-sensitive skin conditions

Michigan allows a medical exemption for people with skin conditions that require protection from ultraviolet (UV) light. Conditions like lupus, porphyria, and severe photosensitivity can may have access to. If you have a may have access to condition, you can tint your front side windows darker than the 50% limit.

To use this exemption, you must carry a letter from your doctor in your vehicle stating that you have a medical condition requiring UV protection. The letter should specify that window tint is medically necessary. Without this documentation, you cannot claim the exemption during a traffic stop. If you are stopped and have the letter, show it to the officer along with your license and registration.

The exemption does not allow you to tint your windshield beyond the visor strip, and it does not override other safety rules. You still need to be able to see adequately while driving.

What happens if you get a tint ticket

A window tint violation in Michigan is a civil infraction, not a criminal charge. The fine amount varies by county and court, but typically ranges from $50 to $100 or more. You will receive a ticket with a court date or a notice to appear.

You have several options when you receive a ticket. You can pay the fine and accept the violation. You can remove the tint and request that the ticket be dismissed — some courts allow this, though it is not may provide. You can also contest the ticket in court and argue that your windows meet the legal standard, or that the meter reading was wrong.

If you choose to remove the tint, keep the receipt from the tint shop or the person who removed it. Bring this receipt to court as evidence that you have corrected the violation. Some judges will dismiss the ticket when you show proof of removal, but this depends on the specific court and judge.

Aftermarket tint versus factory tint

Michigan's tint laws explore to all window tint, whether it was installed at the factory or added aftermarket. If your vehicle came from the manufacturer with tint that is darker than 50% on the front side windows, you still cannot legally drive it in Michigan without removing or lightening that tint. In practice, this is rare — most factory tint on new vehicles complies with state law.

If you have aftermarket tint installed, make sure the shop installs it to meet Michigan's 50% VLT standard on your front side windows. A reputable tint shop in Michigan will know the law and install accordingly. If you are unsure whether your current tint is legal, you can ask a tint shop to meter your windows, or you can contact your local police department's non-emergency line and ask an officer to check for you.

Frequently Asked Questions
