Michigan: Everything You Need to Know

• Michigan Window Tint Exemption Laws

  Michigan allows medical exemptions for window tint under MCL 257.709(3)(e). Individuals who are light sensitive or photosensitive can obtain darker window tint with proper medical documentation.

  • The exemption allows special window treatment on front side windows beyond the standard 4-inch limit.

  • A licensed Michigan physician or optometrist must sign a letter stating the window treatment is a medical necessity.

  • The letter must be in possession of the owner or operator while driving.

  • No specific VLT percentage is mandated – your physician determines the appropriate darkness level.

  • Window tint cannot interfere with or obstruct the driver's clear vision of the highway.

  • Reflectivity must remain below 35% even with a medical exemption.

  • No expiration date – your letter remains valid as long as your condition exists.
• Documents You'll Need

  Michigan has one of the simplest medical exemption processes in the country. You need:

  • A letter signed by a licensed Michigan physician OR optometrist

  • The letter must state that the window treatment is a medical necessity

  • The letter must indicate you are light sensitive or photosensitive

  The letter should include:

  • Your name and the physician's name

  • Date of issuance

  • Your diagnosis/medical condition

  • Statement that window tint is medically necessary

  • Physician's signature and credentials

  If applying through a telehealth service like TintedMD, you can get your evaluation done completely online. You'll receive:

  • A signed physician letter delivered via email within 24-48 hours, ready to keep in your vehicle

  Note:

  Keep the letter in your vehicle at all times. Present it to law enforcement if stopped. No DMV filing is required – the letter itself is your exemption.

• Legal Tint Limits

  Michigan law sets specific limits on window tint. With a medical exemption, you can legally exceed these limits while maintaining safety standards.

  Standard Michigan Tint Limits (Without Exemption):

  • Windshield: Tint permitted only on top 4 inches (or below shade band, whichever is closer to top).

  • Front Side Windows: Tint permitted only on top 4 inches.

  • Back Side Windows: Any darkness permitted (must be nonreflective, under 35% reflectivity).

  • Rear Window: Any darkness permitted (requires dual side mirrors if visibility obstructed).

  • Reflectivity: Maximum 35% on all windows. No gold or silver reflective film permitted.

  With a Medical Exemption:

  • You may install window tint on the full front side windows beyond the 4-inch limit.

  • No specific VLT percentage is mandated by law – your physician determines appropriate darkness.

  • Reflectivity must still remain under 35%.

  • Tint must not obstruct driver's clear vision of highway or intersecting highway.

  • Windshield rules (top 4 inches) generally still apply unless specifically addressed in your letter.
