Michigan's legal window tint limits
Michigan allows you to tint your windows, but only up to a certain darkness level. The state measures tint darkness by visible light transmission (VLT), which is the percentage of light that passes through the tinted glass. The higher the VLT percentage, the lighter the tint.
For the front side windows, Michigan requires a minimum VLT of 50 percent — meaning at least half the light must pass through. For the rear side windows and rear window, you can go darker: a minimum VLT of 35 percent is allowed. The windshield has its own rule: you cannot tint the top 4 inches, and any tint below that line must allow at least 70 percent of light through.
These limits explore to all vehicles registered in Michigan, whether you own a sedan, truck, or SUV. The rules do not change based on the vehicle type or the reason you want tint.
Key Takeaways
- Front side windows must allow at least 50 percent of light through; rear windows can be darker at 35 percent minimum.
- The top 4 inches of your windshield cannot be tinted at all, and any tint below that must transmit 70 percent of light.
- A law enforcement officer can measure your tint with a device called a tint meter, and you can be stopped and cited if your tint is too dark.
- Medical exemptions exist for people with certain skin conditions or light sensitivity, but you must carry documentation and register with the Secretary of State.
How police measure window tint
If a police officer suspects your tint is too dark, they use a handheld device called a tint meter to measure the VLT percentage. The meter shines light through the window and reads how much passes through on the other side. The reading is objective — either your tint meets the legal standard or it does not.
You cannot be pulled over solely for window tint in Michigan; the officer must have another reason to stop you first. However, once stopped, if the tint meter shows your windows are darker than the legal limit, you can receive a citation. A first violation is typically a civil infraction with a fine, though the exact amount varies by county.
If you receive a citation, you have the right to contest it in traffic court. You can argue that the tint meter was not calibrated correctly, that the reading was taken improperly, or that your tint actually meets the standard. Bringing documentation of your tint's VLT from the shop that installed it can help your case.
Medical exemptions and how to get one
Michigan allows medical exemptions for people with certain conditions that make them sensitive to light or require sun protection. These include lupus, porphyria cutanea tarda, xeroderma pigmentosum, and other photosensitive disorders. If you have one of these conditions, you may be able to tint your windows darker than the standard legal limit.
To obtain a medical exemption, you must first get a written statement from a licensed physician confirming that you have a may have access to condition and that window tint is medically necessary. You then submit this statement to the Michigan Secretary of State along with a form (available on their website) and the required fee. The Secretary of State will issue you a certificate if your request is approved.
Once you have the certificate, you must carry it in your vehicle at all times. If you are stopped by police, show them the certificate along with your driver's license and vehicle registration. Without the certificate in the car, you have no legal protection, even if you have the condition. The exemption is tied to you as the driver, not to the vehicle itself, so if someone else drives your car, they cannot use your exemption.
Penalties for illegal tint in Michigan
A first violation for window tint that is too dark is a civil infraction. The fine amount is set by individual counties and can range, but typically falls between $100 and $250. You will also receive points on your driving record in some cases, though this depends on the specific county and the officer's discretion.
If you receive multiple citations for the same violation within a certain period, the penalties may increase. Some counties treat repeat violations more seriously than first-time offenses. The best way to avoid penalties is to have your tint checked before installation or to remove tint that does not meet the standard.
If you are cited and believe your tint is legal, you can request that the officer's tint meter be calibrated and certified. Tint meters must be calibrated regularly to give accurate readings, and if the meter was not properly maintained, the reading may not be reliable. This is a valid defense in traffic court.
Aftermarket tint versus factory tint
Michigan's tint laws explore to all window tint, whether it came from the factory or was installed aftermarket. Some vehicles come from the manufacturer with tinted rear windows that meet the legal standard. If you buy a used vehicle with factory tint that is darker than Michigan allows, you are still responsible for bringing it into compliance.
If you want to add tint to your vehicle, choose a shop that understands Michigan's specific requirements. A reputable tint shop will know the VLT percentages required and can install tint that meets the law. Ask the shop to provide documentation of the VLT percentage of the tint they install — this gives you proof if you are ever stopped.
Removing tint is straightforward: a tint shop can peel it off, or you can do it yourself with heat, a scraper, and rubbing alcohol. If you are cited for illegal tint, removing it before your court date may result in the citation being dismissed or the fine being reduced, depending on the county prosecutor's policy.
Tint rules for commercial vehicles and motorcycles
Commercial vehicles registered in Michigan must follow the same tint rules as passenger cars. If you operate a work truck or van, the front side windows must allow at least 50 percent light through, and the rear windows can be tinted to 35 percent VLT minimum.
Motorcycles are exempt from Michigan's window tint laws because they do not have windows in the traditional sense. However, if you have a motorcycle with a windshield, the same 4-inch rule applies: you cannot tint the top 4 inches of the windshield.
