Pennsylvania: Everything You Need to Know

• Pennsylvania Window Tint Exemption Laws

  Pennsylvania's medical window tint exemption is authorized under 75 Pa.C.S. § 4524 and administered by the Pennsylvania Department of Transportation (PennDOT). Individuals with qualifying photosensitive conditions can receive certification from licensed physicians or optometrists and legally install sun screening material on their vehicle windows.

  • The exemption allows colorless sun screening material that filters ultraviolet light on the windshield, side windows, and rear window.
  • Pennsylvania only permits colorless (clear) UV-filtering materials—this provides UV protection while maintaining visibility.
  • Exemption certificates have no expiration date and are valid for the lifetime of vehicle ownership.
  • Certificates are vehicle-specific and become void upon sale or transfer of the vehicle.
  • A licensed physician or optometrist must certify your condition on Form MV-402.
  • Qualifying conditions include any photosensitive condition for which protection from ultraviolet light would be beneficial.
  • The exemption certificate must be kept in your vehicle at all times and presented to law enforcement upon request.
  • Upon sale or transfer, you must remove the sun screening material, destroy the certificate, and provide the buyer with a notarized statement.

• Legal Tint Limits

  Pennsylvania 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, you can legally install colorless UV-filtering material on your windows, protecting both your health and your compliance with Pennsylvania law.

  Standard Pennsylvania Tint Limits (Without Exemption):

  • Windshield: 70% VLT required. No tint permitted below the AS-1 line without exemption.
  • Front Side Windows: Must allow at least 70% of visible light (70% VLT). Anything darker is illegal without an exemption.
  • Back Side Windows: Must allow at least 70% VLT for sedans; SUVs and vans have no restriction.
  • Rear Window: Must allow at least 70% VLT for sedans; SUVs and vans have no restriction.

  With a Medical Exemption:

  • You may install colorless sun screening material that filters ultraviolet light on all windows, including the windshield.
  • Pennsylvania permits colorless (clear) UV-filtering products that block harmful UV rays while maintaining visibility.
  • Exemption covers windshield, all side windows, and rear window.
  • Products like crystalline tint offer superior UV protection while remaining colorless.
  • The physician determines appropriate sun screening based on your medical condition.
