New Hampshire: Everything You Need to Know

• New Hampshire Window Tint Exemption Laws

  New Hampshire's medical window tint exemption is authorized under RSA 266:58-a and RSA 266:61-a, IX, and administered under Administrative Rules Saf-C 2500. Individuals with qualifying photosensitive conditions can receive a medical waiver from the Commissioner of the Department of Safety and legally install darker window tint.

  • The exemption allows aftermarket tinting on the windshield and the windows to the left and right of the driver.
  • A physician licensed to practice in any U.S. state must complete Form DSMV 603.
  • Qualifying conditions include extreme intolerance to light, allergic reactions to the sun, melanoma, lupus, porphyria, or any other medical condition aggravated by sun exposure that sunglasses or other protective equipment will NOT alleviate.
  • Medical waivers are valid for 2 years, or up to 4 years if the physician documents a lasting medical necessity.
  • Up to 2 vehicles may be listed on a single waiver.
  • The waiver permit (Form DSMV 473) must be kept in the vehicle at all times.
  • The DMV must respond within 20 days of receiving the application.

• Legal Tint Limits

  New Hampshire 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 waiver, your darker window tint becomes legally recognized, protecting both your health and your compliance with New Hampshire law.

  • Windshield: No aftermarket tinting allowed (only non-reflective tint on top 6 inches, minimum 35% VLT).

  • Rear Window: Must allow at least 35% VLT (sedans); any darkness allowed (SUVs/MPVs).
