Rear Side Windows and Rear Window Have no fixed darkness limit; any darkness is allowed.

If the rear window is tinted, the vehicle must have side mirrors that provide adequate rear visibility on both sides.

Exemptions Exist for medical reasons with proper documentation; other exemptions may apply for certain vehicle types.

What New Hampshire Law Allows

New Hampshire tint regulations are designed to preserve driver visibility while allowing some tint for privacy. For passenger vehicles, the key constraint is on the front side windows, which must admit a minimum level of light. The windshield must remain non-reflective, and tinting on the windshield is generally restricted to a clear band at the top rather than a full tint. The rear windows, including the rear windshield, may be tinted more darkly, but the vehicle must be equipped with two functional side mirrors if the rear window is tinted. This ensures safe lane changes and a clear view of traffic behind the vehicle.

Exemptions And Documentation

Medical exemptions are available in New Hampshire. The process typically requires a diagnosis from a licensed medical professional and formal documentation to be kept in the vehicle record. Some exemptions may be granted for temporary or permanent medical conditions that necessitate reduced glare or enhanced privacy. Vehicles with exemptions should carry the appropriate paperwork to present to law enforcement if questioned. It is important to verify the current forms and submission requirements with the state’s department of motor vehicles or a trusted legal resource, as procedures can change.

Compliance Tips For Vehicle Owners

  • Measure VLT accurately: Use a certified tint installer who can provide a written VLT specification for front side windows (minimum 35%).
  • Check windshield tint: Keep tint non-reflective and ensure any permitted top-band tint complies with local guidelines and does not violate visibility standards.
  • Rear windows and mirrors: If the rear window is tinted, confirm that side mirrors are installed and in good working order to meet visibility requirements.
  • Medical exemptions: Obtain and carry the required documentation. Confirm that the documents are current and accepted by NH authorities.
  • Documentation: Retain receipts, permit numbers, and manufacturer or installer specifications in the vehicle—ready for inspection.
  • State updates: Tint laws can change; check the New Hampshire Department of Transportation or DMV for the latest rules before a tint purchase.

Enforcement And Penalties

Law enforcement officers may inspect window tint during traffic stops or vehicle inspections. If the tint on the front side windows fails to meet the 35% VLT requirement or the windshield tint violates the non-reflective rule, a citation may be issued. The penalties can include a corrective order to remove or alter the tint to meet compliance and, in some cases, fines. Vehicles failing to have functional side mirrors when rear windows are tinted may also incur penalties. Addressing non-compliance promptly reduces the risk of repeated stops and monetary fines.

Practical Considerations For Buyers

When shopping for window tint in New Hampshire, consider these practical points:

  • Choose reputable installers: Seek installers with verifiable certifications and clearly documented tint specifications.
  • Request written guarantees: Ensure the installer provides a written statement of the tint’s VLT and a policy for corrections if the tint is later deemed non-compliant.
  • Plan for future inspections: If you anticipate changes in law or exhaustively check for updates, schedule periodic reviews of your vehicle’s tint status.
  • Medical exemption readiness: If applying for an exemption, start the documentation process early to avoid delays in permit approval.
  • Vehicle type considerations: SUVs and passenger cars may face different enforcement emphasis; verify the rules for your specific vehicle class.

Common Mistakes To Avoid

  • Assuming all tinted windows must meet a single darkness standard; NH allows darker rear windows but not on the front side.
  • Installing tint that appears compliant but exceeds the 35% VLT on the front side windows.
  • Neglecting to verify that the windshield tint is non-reflective and restricted to a permissible top band.
  • Relying on outdated or non-official sources for the latest exemptions or procedural steps.
  • Forgetting to carry documentation for medical exemptions when driving or undergoing inspections.
