Window Tint Laws in New Hampshire: What is Legal and How to Fight a Citation
New Hampshire enforces strict window tint standards. Under state law, front side windows must allow at least 70% visible light transmission (VLT), while rear side windows and the rear windshield can be tinted down to 35% VLT. Aftermarket tint on the windshield is prohibited, except for a sunstrip along the top 6 inches with at least 35% VLT or with an approved medical waiver.
Understanding Window Tint Restrictions in New Hampshire
If you enjoy customizing your vehicle, you need to be very careful when driving in the Granite State. Under N.H. Rev. Stat. § 266:58-a, aftermarket tint on windows to the left and right of the driver must allow at least 70% visible light transmission (VLT), while rear side windows and the rear windshield may be tinted down to 35% VLT. Aftermarket windshield tint is illegal, except for a sunstrip along the top 6 inches that allows at least 35% VLT. The state enforces these standards aggressively for officer safety, allowing police to have a clear view into a vehicle during traffic stops. Violating these rules can result in a traffic citation, and noticeable illegal tint gives police reasonable suspicion to initiate a traffic stop.
However, there are strict exceptions to this rule. Residents with specific medical conditions that cause severe light sensitivity, such as photophobia, can apply for a medical exemption. Additionally, the laws can create headaches for people moving to the state or buyers who purchased used cars out-of-state with pre-installed tint. If you have been cited for illegal tint and need help navigating a fix-it ticket, consider reaching out to a local traffic attorney from our directory.
Step-by-Step Guide to Applying for a Medical Exemption
If you have a legitimate medical reason for needing tinted front windows, you cannot simply show a doctor's note to a police officer. You must obtain an official exemption from the New Hampshire Division of Motor Vehicles, Concord.
Step 1: Consult Your Physician
You must schedule an appointment with a licensed physician. The doctor needs to confirm that you suffer from a medical condition (such as lupus, albinism, or severe photophobia) that requires you to be shielded from direct sunlight or UV rays while driving.
Step 2: Complete the Official Exemption Form
You and your physician must fill out Form DSMV 603, New Hampshire, Division of Motor Vehicles, Application for Medical Waiver of After Market Tinting Restriction authorized under N.H. Rev. Stat. § 266:61-a. Your physician must sign the document detailing the medical necessity. Once completed, you mail this form to the DMV headquarters.
Step 3: Carry the Permit in Your Vehicle
If the DMV approves your application, they will issue you a special medical tint certificate. You must keep this certificate inside your glove compartment at all times. If you are pulled over by a state trooper or local police officer, presenting this certificate immediately will prevent you from being cited for an equipment violation.
How to Handle a Window Tint 'Fix-It' Ticket
If you are cited for illegal tint in cities like Manchester, Portsmouth, or Nashua, the ticket often operates as a 'fix-it' ticket (an equipment violation). Here is what you generally need to do:
- Remove the Tint: You must physically remove the illegal film from your windshield or front side windows. You can do this yourself using a steamer and razor blade, or pay a professional auto detailer.
- Get an Inspection: Drive your vehicle to a local police department or certified state inspection station. An officer or mechanic will inspect the vehicle to verify that the illegal tint has been removed and sign off on your citation.
- Submit to the Court: Bring or mail the signed-off citation to the local district court listed on your ticket, such as the 10th Circuit Court - District Division - Portsmouth, Portsmouth, before the deadline. Often, fixing the issue promptly will result in the fine being reduced or the ticket being dismissed entirely.
What if I am an Out-of-State Driver?
Many drivers visiting from neighboring states like Massachusetts or Maine (which allow front window tinting) wonder if they can be ticketed in New Hampshire. Generally, if your vehicle is legally registered in your home state and complies with your home state's equipment laws, you are exempt from New Hampshire's tint rules while briefly visiting. However, if you are pulled over, you may still have to politely explain that your vehicle complies with your home state's regulations. If an officer issues a ticket anyway, an attorney can usually get it easily dismissed by providing proof of your out-of-state registration and compliance.
How Much Does a Tint Citation Cost?
The penalties for driving with illegal tint are primarily financial, but failing to address the ticket can lead to larger problems.
| Standard Fine | Typically $62 to $124 per offense (including penalty assessments) |
| Fix-it Dismissal | Often reduced to $0 or a small administrative fee if fixed promptly |
| Professional Tint Removal | $50 to $150 (Depending on the shop) |
| Failed State Inspection | Your car will fail its annual safety inspection until the tint is removed |
Frequently Asked Questions (FAQ)
Can I have any tint on my front driver and passenger windows?
Yes, but it must be very light. Under N.H. Rev. Stat. § 266:58-a, aftermarket tint on the windows to the left and right of the driver is permitted as long as it has a Visible Light Transmission (VLT) of at least 70%. Darker tint on front side windows is illegal without an approved medical waiver.
What is the legal tint limit for rear windows?
For the rear side windows and the rear windshield, you are allowed to have a window tint with a Visible Light Transmission (VLT) of no less than 35%.
I bought a used car with tinted windows. Am I still liable?
Yes. The driver of the vehicle is legally responsible for ensuring the car complies with state equipment laws. Even if you bought the car with the tint already installed, you can be ticketed and it will fail the state safety inspection.
Does factory tint count as illegal tint?
No. Factory tint (which is a pigment applied directly into the glass during manufacturing, usually reading at about 70% VLT) is federally regulated and perfectly legal. The state law only restricts aftermarket film applied to the glass.
Can a doctor from another state fill out my medical exemption form?
Yes. The official instructions for Form DSMV 603, New Hampshire, Division of Motor Vehicles, Application for Medical Waiver of After Market Tinting Restriction explicitly allow the application to be completed and signed by a physician licensed to practice medicine in any state of the U.S.
