Legal Window Tint Limits in New Mexico: Fighting Equipment Violation Tickets

With over 300 days of intense high-elevation sunshine a year in Albuquerque, Las Cruces, Santa Fe, and Roswell, aftermarket window tint is a practical necessity for New Mexico drivers. However, darkly tinted windows are also one of the most common pretexts used by New Mexico State Police, county sheriffs, and municipal officers to initiate traffic stops and conduct roadside photometer inspections.

Understanding the exact statutory differences between sedans and SUVs, knowing whether New Mexico's tint law even applies to out-of-state license plates, and following the court clerk's fix-it dismissal procedure can keep an equipment violation off your record without costing you a single dollar in court fines.

Visible Light Transmission (VLT) Percentages for Front, Back, and Side Windows

New Mexico regulates automotive window tint (officially called sun screening material) under N.M. Stat. Ann. § 66-3-846.1 and N.M. Stat. Ann. § 66-3-846. Visible Light Transmission (VLT) measures the percentage of total outside light that passes through both the aftermarket film and the factory automotive glass combined. Crucially, New Mexico sets different rules for passenger cars versus SUVs, pickup trucks, and vans:

• Front Windshield (All Vehicles): Under N.M. Stat. Ann. § 66-3-846.1 Subsection B(1), sun screening material applied to the front windshield must be non-reflective, cannot be red, yellow, or amber in color, and may be used only along the top strip of the windshield-never extending downward beyond the glass manufacturer's AS-1 (ASI) line or more than 5 inches from the top of the windshield, whichever is closer to the top.
• Front Side Windows (Driver and Front Passenger): Under N.M. Stat. Ann. § 66-3-846.1 Subsection B(2), the front left and front right side windows on all motor vehicles must allow a light transmission of not less than 20% VLT and must be non-reflective. Because factory automotive glass already blocks 15% to 25% of light, applying a 20% aftermarket film over factory glass will often drop the combined reading to 15% or 16% VLT-triggering a citation when tested by an officer's tint meter!
• Rear Side Windows and Back Windshield on Sedans and Coupes: For standard passenger cars (sedans, coupes, and hatchbacks), the 20% minimum VLT rule applies to every side window and the rear window (N.M. Stat. Ann. § 66-3-846.1 Subsection B(2)).
• Rear Side Windows and Back Windshield on SUVs, Pickup Trucks, and Vans: Under N.M. Stat. Ann. § 66-3-846.1 Subsection F, the 20% VLT restriction does not apply to any windows behind the driver on multipurpose passenger vehicles (SUVs, minivans, and crossovers), pickup trucks, truck tractors, buses, recreational vehicles, and motor homes. On these vehicles, rear passenger windows and the back windshield can legally be tinted to any darkness (including 5% limo tint).
• Mandatory Dual Outside Mirrors & Compliance Stickers: Any vehicle with tinted windows in New Mexico must be equipped with both a left and right outside rearview mirror (N.M. Stat. Ann. § 66-3-846.1 Subsection B(2)), and installers must permanently place a compliance certification sticker between the film and glass on each tinted window under Subsection C.

The Out-of-State License Plate Defense

What if you are driving through New Mexico with valid Texas, Arizona, or Colorado plates, or you are an out-of-state student or temporary worker? Subsection A of N.M. Stat. Ann. § 66-3-846.1 explicitly states that New Mexico's window tint law applies only to a motor vehicle that is registered or required to be registered in this state. Under the plain language of N.M. Stat. Ann. § 66-3-846.1(A), an out-of-state vehicle that is not required to be registered in New Mexico under the 180-day nonresident rule (N.M. Stat. Ann. § 66-3-301) cannot violate N.M. Stat. Ann. § 66-3-846.1-making a stop or citation based solely on that statute legally invalid.

Medical Exemptions for Darker Tint in New Mexico

If you or a family member who regularly rides in your vehicle suffers from lupus, melanoma, solar urticaria, porphyria, albinism, or severe photosensitivity, New Mexico provides a statutory exemption allowing window tint darker than 20% VLT. Under N.M. Stat. Ann. § 66-3-846.1 Subsection E, you do not have to pay an application fee to the Motor Vehicle Division for a special sticker, provided you follow three strict legal rules:

1. Licensed New Mexico Physician or Optometrist: You must obtain a written, signed affidavit from a physician (M.D. or D.O.) or optometrist (O.D.) licensed to practice in the State of New Mexico (drivers updating medical restrictions on their license file may also use Form MVD-10124, New Mexico, Motor Vehicle Division, Medical Report Form or Form MVD-10125, New Mexico, Motor Vehicle Division, Request for Ophthalmologic or Optometric Information Form with the New Mexico Motor Vehicle Division, Santa Fe).
2. Specific Statement of Medical Necessity: The signed affidavit must explicitly state that the named patient has a physical condition that makes it medically necessary to equip the motor vehicle with sun screening material that exceeds the standard limits of N.M. Stat. Ann. § 66-3-846.1.
3. Must Be Carried Inside the Vehicle at All Times: Under N.M. Stat. Ann. § 66-3-846.1 Subsection E, the medical affidavit must be in the possession of the person with the physical condition (or their legal guardian) at all times while being transported in the vehicle. If a family member drives the car alone without the medically exempt passenger inside, the exemption does not protect that solo trip.

Step-by-Step on How to Resolve a 'Fix-It' Ticket for Illegal Tint and Pay the Dismissal Fee

If you are cited for illegal window tint under N.M. Stat. Ann. § 66-3-846.1, New Mexico Magistrate Courts and the Bernalillo County Metropolitan Court allow you to resolve the citation as a correctable equipment ('fix-it') ticket without a court hearing:

• Step 1: Verify Your 30-Day Response Window: Look at the bottom of your Uniform Traffic Citation to confirm your 30-day deadline under N.M. Stat. Ann. § 66-8-116 and identify the court of jurisdiction-such as Bernalillo County Metropolitan Court, Albuquerque, Doña Ana County Magistrate Court, Las Cruces, Santa Fe County Magistrate Court, Santa Fe, or Otero County Magistrate Court, Alamogordo. Do not pay the penalty assessment online if you want the ticket dismissed, because paying the fine acts as a guilty plea!
• Step 2: Have a Commercial Auto Shop Remove or Replace the Tint: Under New Mexico Magistrate Court Local Rules (such as Rule 12-MCLR-101), self-removal in your driveway is often rejected unless a court clerk personally inspects the vehicle. Take your car to a commercial auto glass, tinting, or repair shop to strip the illegal film (or install legal 20%+ VLT film) and get an official shop invoice showing the business name, date, your vehicle's VIN/plate, and confirmation that the window tint violation was remedied (for MVD VIN/equipment verifications, inspectors use Form MVD-10053, New Mexico, Motor Vehicle Division, Vehicle Equipment Affirmation).
• Step 3: Submit Proof of Repair to the Court Clerk: Present your citation and the commercial repair receipt (or your pre-existing notarized medical affidavit under N.M. Stat. Ann. § 66-3-846.1 Subsection E) to the court clerk's walk-in window or online compliance portal before your 30-day deadline.
• Step 4: Pay the Dismissal Fee ($0 in State Courts / Up to $10 in Municipal Courts): Once the clerk verifies the commercial repair receipt, the citation is dismissed. In all New Mexico Magistrate Courts and the Bernalillo County Metropolitan Court, the dismissal fee is $0 (following the repeal of N.M. Stat. Ann. § 66-8-116.3). If your ticket was written by city police into a local Municipal Court under a municipal traffic ordinance, an administrative fee of $0 to $10 under N.M. Stat. Ann. § 66-8-130 may apply.

How Much Does it Cost in New Mexico?

Here is the exact breakdown of costs when resolving a New Mexico window tint citation:

• State Penalty Assessment Fine (If You Do Not Fix It): $25 base penalty assessment in state Magistrate or Metropolitan Court under N.M. Stat. Ann. § 66-8-116 (since New Mexico repealed the $52 to $61 in add-on court fees formerly charged under N.M. Stat. Ann. § 66-8-116.3).
• Municipal Court Ordinance Fine (If Cited in City Court): $50 to $75 (plus a $10 municipal fee under N.M. Stat. Ann. § 66-8-130) in cities such as Albuquerque, Santa Fe, Las Cruces, or Hobbs that prosecute tint violations under the New Mexico Uniform Traffic Ordinance.
• Court Dismissal Fee (Fix-It Ticket): $0 in state Magistrate and Metropolitan Courts upon presenting a commercial shop receipt showing the illegal tint was removed.
• Commercial Tint Removal Cost: $40 to $120 at a local New Mexico tint shop to professionally steam off and remove non-compliant film from two front windows.
• Traffic Attorney Fees (For Pretextual Stop Suppression): If an unlawful window tint stop led to a vehicle search or criminal charges, hiring a New Mexico defense attorney from our directory (typically $1,500 to $4,000+) can help you file a Motion to Suppress Evidence under Article II, Section 10 of the New Mexico Constitution.

How Long Does the Process Take?

From the date the officer hands you a window tint citation, you have 30 days to either present proof of commercial tint removal for a fix-it dismissal, pay the penalty assessment, or request a court hearing. Having a local tint shop remove the film takes about 30 to 60 minutes, and the court clerk can process your dismissal at the counter in 10 minutes.
