Idaho: Everything You Need to Know

• Idaho Window Tint Exemption Laws

  Idaho's medical window tint exemption is authorized under Idaho Code § 49-944(4). Individuals who must be protected from exposure to sunlight or heat for medical reasons can obtain written verification from a licensed physician and legally install darker window tint.

  • The exemption allows darker tint on the windshield (70% VLT minimum) and all other windows (20% VLT minimum).
  • Written verification from a licensed physician must be carried in the vehicle at all times.
  • The exemption applies to vehicles operated by, or carrying as a passenger, a person with physician verification.
  • Idaho does not require a state-issued certificate or specific form – only a physician's written verification.
  • There's no expiration date for the exemption.

• Legal Tint Limits

  Idaho law sets specific limits on how dark your vehicle windows can be tinted. With an approved medical exemption, darker window tint becomes legally recognized under Idaho Code § 49-944(4).

  Standard Idaho Tint Limits (Without Exemption):

  • Rear Window: Must allow more than 35% of visible light (35% VLT).

  • Front Side Windows: 20% VLT minimum (15% darker than standard).
  • Back Side Windows: 20% VLT minimum.
  • Rear Window: 20% VLT minimum (15% darker than standard).
