Connecticut: Everything You Need to Know

• Connecticut Window Tint Exemption Laws

  Connecticut's medical window tint exemption is authorized under Connecticut General Statutes § 14-99g and administered by the Connecticut Department of Motor Vehicles (DMV). Individuals with qualifying photosensitive conditions can receive certification from licensed physicians or optometrists and legally install darker window tint.

  • The exemption allows window tint between 32% and 20% VLT on side and rear windows (standard limit is 35% VLT).
  • Exemption applies to vehicles you own or in which you are a "usual passenger."
  • Exemption certificates have no expiration date specified in Connecticut law.
  • A licensed physician or optometrist must complete and sign Form E-220.
  • Qualifying conditions include being "required for medical reasons to be shielded from direct rays of the sun."
  • After receiving your physician-signed Form E-220, you must have your windows tinted and then bring your vehicle to the Wethersfield or Hamden DMV inspection lane for validation.
  • The validated Form E-220 must be carried in your vehicle at all times.
  • Compliance stickers are NOT affixed to exempted vehicles.
  • Window tint darker than 20% VLT will fail measurement and will not be granted an exemption.
• Documents You'll Need

  To apply for a new medical window tint exemption in Connecticut, you'll need:

  • Form E-220 (Application & Special Permit for Exemption from Tinted Window Requirements), completed and signed by a licensed MD, DO, or Optometrist in Connecticut

  After Receiving Your Completed Form E-220:

  1. Take your Form E-220 to a window tint installer and have your windows tinted (must be between 20% and 32% VLT)
  2. Bring your tinted vehicle and completed Form E-220 to the Wethersfield or Hamden DMV inspection lane
  3. The Commercial Vehicle Safety Division will measure your tint and validate your Form E-220 on site

  Important: Window tint darker than 20% VLT will fail measurement and you will be referred to the Medical Review Unit.

  Note: The validated Form E-220 must be carried in your vehicle at all times and presented to law enforcement upon request.

• Legal Tint Limits

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

  Standard Connecticut Tint Limits (Without Exemption):

  • Windshield: Non-reflective tint permitted only above the AS-1 line (at least 29 inches above the driver's seat). Tint below this line is prohibited.
  • Front Side Windows: Must allow more than 35% of visible light (35% VLT ±3%). Anything darker is illegal without an exemption.
  • Back Side Windows: Must allow more than 35% of visible light (35% VLT ±3%) on sedans; SUVs and multipurpose vehicles may use any darkness on rear side windows.
  • Rear Window: Any darkness allowed when equipped with left and right side mirrors (per C.G.S. § 14-99g).
  • Front Side Reflectivity: No more than 21% reflective.
  • Back Side Reflectivity: No more than 27% reflective.

  With a Medical Exemption:

  • You may install window tint darker than the standard 35% VLT limit, down to a minimum of 20% VLT.
  • Exemption allows tint between 32% and 20% VLT on side and rear windows.
  • Tint darker than 20% VLT will not be approved and will be referred to the Medical Review Unit.
  • Windshield tinting below the AS-1 line is generally not permitted even with exemption.
