MVD
Interlock licenses are issued by the New Mexico MVD
The application and approval process goes through MVD, separate from any criminal court requirements.
DUI / DWI Defense
Interlock License
An ignition interlock license allows certain drivers charged with or convicted of DUI or DWI to continue driving legally while complying with court or Motor Vehicle Division (MVD) requirements. While restrictive, an interlock license is often the only way to maintain lawful driving privileges after a DUI-related license action.
Important
This is general information, not legal advice. If an arrest happened recently or you believe you are under investigation, do not explain anything to law enforcement before speaking with counsel.
Overview
An interlock license allows limited legal driving while an ignition interlock device is installed and monitored.
If your driver's license is revoked or restricted due to a DUI or DWI, you may be eligible for an ignition interlock license. This license permits driving only in vehicles equipped with an approved ignition interlock device. Compliance is mandatory, and violations can result in additional penalties or extended restrictions.
An ignition interlock license is a restricted driver's license that requires the driver to use a breath-testing device before starting the vehicle. The device prevents the car from starting if alcohol is detected. The license is tied to compliance with both criminal court and MVD requirements.
Who typically needs one: drivers convicted of DUI or DWI; drivers who refused chemical testing; drivers seeking limited driving privileges after revocation; drivers required by statute to use ignition interlock. Eligibility depends on the charge level, prior history, and compliance with required steps.
Once required, the driver must obtain an approved ignition interlock device, gather the required documentation, and apply through the MVD. A temporary paper license is usually issued while the permanent interlock license is processed.
Key points
Device
You must install an approved ignition interlock device
Only authorized providers may install interlock devices. Using an unapproved device is a violation.
Restriction
Driving without the device is not permitted
Operating any vehicle not equipped with the interlock is a violation, regardless of whose vehicle it is.
Violations
Violations can extend interlock requirements
Failed tests, missed calibrations, or tampering restart the compliance clock and may trigger additional penalties.
Requirements & Process
What the MVD requires
To apply for an interlock license, you generally must provide: valid proof of identification; proof of insurance; a contract from an authorized ignition interlock provider; a notarized MVD Ignition Interlock Affidavit; payment of the required license fee.
You may apply in person at: New Mexico MVD Field Office – Santa Fe, 2546 Camino Entrada, Santa Fe, NM 87507 (Hours: Monday–Friday, 8:00 AM–4:00 PM, Phone: (505) 476-1599); or MVD Express – Santa Fe, 850 St Michaels Dr, Santa Fe, NM 87505 (Phone: (505) 217-0024, Hours: Monday–Saturday, 8:00 AM–6:00 PM).
The annual fee for an ignition interlock license is $113.00. Additional costs apply for installation, monthly monitoring, and maintenance of the interlock device, which are paid directly to the provider.
After applying, you will typically receive a temporary paper interlock license, which is valid until your permanent license is mailed.
Compliance & Risks
Driving restrictions and violation consequences
You may only drive vehicles equipped with an approved ignition interlock device. Driving any other vehicle is a violation and can result in additional penalties.
Missed calibrations, failed tests, tampering, or driving without the device can: extend the length of the interlock requirement; trigger additional MVD action; create new criminal or probation violations.
Interlock requirements can last months or years depending on the offense level. Full compliance is essential to avoid restarting or extending the restriction period.
How legal guidance helps
Common issues we address
Eligibility
Determining eligibility for an interlock license
Not everyone qualifies automatically. Prior offense history, charge level, and compliance status all factor in.
Coordination
Coordinating court orders with MVD requirements
Court and MVD timelines often diverge. Coordinating them avoids gaps that can trigger violations or extensions.
Violations
Addressing alleged violations or extensions
If MVD alleges a violation or attempts to extend your requirement, legal guidance can help you respond effectively.
Timelines
Ensuring compliance timelines are accurate
MVD records can contain errors. Verifying your timeline and required compliance period is essential before you are deemed complete.
Common Questions
Interlock license — frequently asked
Quick answers to the questions we hear most often. Every case is different — call for a private consultation.
How long do I have to keep the ignition interlock device installed?
The required interlock period depends on your offense level and prior history. First-offense DUI may require one year; higher offenses or aggravated charges require longer periods. If a violation occurs during the interlock period, the requirement may be extended. MVD tracks your compliance and determines when you have completed the requirement.
Can I drive someone else's vehicle while on an interlock license?
Only if that vehicle is also equipped with an approved ignition interlock device. Operating any vehicle without the device — including a rental car or a family member's vehicle — is a violation. This applies regardless of whose vehicle it is or the reason for driving it.
What happens if the interlock device fails or gives a false positive?
If the device records a failed or skipped test, MVD will receive that data. False positives can occur due to certain foods, mouthwash, or medical conditions. You should document the situation and contact your provider and counsel immediately. Challenging a false positive requires prompt action and supporting documentation.
Do I need an interlock license even if my criminal case was not convicted?
Possibly. MVD's administrative revocation process is separate from criminal court. Even if criminal charges are reduced or dismissed, the administrative license revocation may still require an interlock device as a condition of reinstating driving privileges. The two proceedings operate independently.
How do I apply for an interlock license?
You must apply in person at an MVD field office with required documentation: valid ID, proof of insurance, a signed contract with an authorized interlock provider, a notarized MVD Interlock Affidavit, and the license fee. Processing time varies. A temporary paper license is typically issued immediately while the permanent license is prepared.
