Massachusetts: Everything You Need to Know

• Massachusetts Window Tint Exemption Laws

  Massachusetts' medical window tint waiver is authorized under Massachusetts General Laws Chapter 90, Section 9D and administered by the Registry of Motor Vehicles (RMV) Medical Affairs division. Individuals who are photophobic or photosensitive can obtain a waiver allowing darker window tint with physician certification.

  • The exemption is available for private passenger vehicle owners or operators who are certified as photophobic/photosensitive by a licensed physician.
  • A Massachusetts-licensed physician must provide written attestation certifying the medical necessity.
  • Applications are reviewed by the Medical Advisory Board established under M.G.L. Chapter 90, Section 8C.
  • Upon approval, the RMV Registrar issues an exemption sticker that must be affixed to the side window immediately adjacent to the operator.
  • The waiver applies to the specific vehicle listed on the application.
  • Windshields may not be tinted below the AS-1 line (top 6 inches only) even with a waiver.
  • Standard violations carry fines up to $250, with license suspension up to 90 days for third or subsequent convictions.

• Legal Tint Limits

  Massachusetts law sets specific limits on how dark your vehicle windows can be tinted. However, the Commonwealth recognizes that certain medical conditions require additional protection from sunlight. With an approved tinted glass waiver from the RMV, your darker window tint becomes legally recognized, protecting both your health and your compliance with Massachusetts law.

  Standard Massachusetts Tint Limits (Without Waiver):

  • Windshield: No tinting material allowed except on top 6 inches (AS-1 line).
  • Front Side Windows: Must allow at least 35% of light in (35% VLT minimum).
  • Rear Side Windows: Must allow at least 35% of light in (35% VLT minimum).
  • Rear Window: Must allow at least 35% of light in (35% VLT minimum).
  • Reflectivity: Maximum 35% reflectance allowed.

  With a Medical Waiver:

  • You may have tint darker than 35% VLT on front side windows, rear side windows, and rear window.
  • Windshields may NOT be tinted below the AS-1 line (top 6 inches), even with a waiver.
  • Vehicle must have two outside mirrors if rear window is tinted darker.
  • An RMV-issued sticker must be displayed on the side window adjacent to the operator.
