Last updated: 2026-03-27

Overview

New Mexico uses both DWI (Driving While Intoxicated) and DUI (Driving Under the Influence) terminology, with DWI being the more common legal term in statutes. The state has historically had some of the highest DWI fatality rates in the nation, leading to aggressive enforcement and penalty reforms. New Mexico uses a lifetime lookback for felony DWI — a fourth DWI offense is always a felony regardless of time elapsed. The state has a robust ignition interlock program and was one of the first states to mandate IID for all first-time DWI offenders. New Mexico also imposes vehicle seizure and forfeiture for repeat offenders.

Implied Consent Law

Under New Mexico's Implied Consent Act (NMSA 1978 § 66-8-107), any person who operates a motor vehicle in the state is deemed to have consented to chemical testing of breath or blood when a law enforcement officer has reasonable grounds to believe the person has been driving while intoxicated.

Refusal penalties: First refusal: 1-year license revocation (administrative). Subsequent refusal: 1-year revocation. No IID license is available during a refusal revocation — the driver cannot drive at all. Refusal can be introduced as evidence in court. The refusal revocation is separate from and may run consecutive to any DWI conviction suspension.

Aggravating Factors

Factor	Impact
BAC of 0.16% or higher (Aggravated DWI)	Mandatory minimum 48-hour jail for first offense; enhanced jail minimums for all offense levels; mandatory community service
Refusal to submit to chemical testing	1-year license revocation with no IID license option; refusal admitted as evidence at trial
Causing great bodily harm or death	Elevated to Great Bodily Harm by Vehicle (3rd-degree felony, up to 6 years) or Homicide by Vehicle (2nd-degree felony, up to 15 years)
Minor passenger under age 18	Additional child abuse or endangerment charges possible; enhanced sentencing consideration
Driving on a revoked license due to prior DWI	Separate misdemeanor charge (Driving While License Revoked for DWI) with additional mandatory jail time; vehicle subject to seizure
Prior felony DWI conviction	Any subsequent DWI is automatically a felony; mandatory 18-month prison sentence; vehicle forfeiture

DUI with Injury

Classification: 3rd-degree Felony — Great Bodily Harm by Vehicle (NMSA § 66-8-101); 2nd-degree Felony — Homicide by Vehicle (NMSA § 66-8-101)

Great Bodily Harm by Vehicle while DWI: 3rd-degree felony carrying up to 6 years imprisonment and up to $5,000 in fines. Homicide by Vehicle while DWI: 2nd-degree felony carrying up to 15 years imprisonment and up to $12,500 in fines. Mandatory license revocation. Restitution to victims required. Vehicle forfeiture is mandatory for DWI-related vehicular homicide.

Underage DUI

Zero tolerance: Yes

BAC limit: 0.02%

Drivers under 21 with BAC of 0.02% or higher face a 1-year license revocation for a first offense and a 2-year revocation for a second offense. Mandatory alcohol screening and education program. Community service of 24 hours for first offense. If BAC is 0.08% or higher, the underage driver faces the same adult DWI criminal penalties in addition to underage sanctions. Any underage DWI conviction delays full license eligibility.

Diversion Programs

Program: DWI/Drug Court / Conditional Discharge

New Mexico operates DWI/Drug Courts in multiple judicial districts (including Bernalillo County Metro Court, which has one of the nation's oldest DWI Courts). These programs provide intensive supervision, mandatory treatment, random testing, frequent court appearances, and graduated sanctions over 12 to 24 months. Successful completion may result in reduced sentences. New Mexico does not offer pretrial diversion for DWI specifically, but the conditional discharge statute allows first-time offenders to plead guilty and have the conviction deferred pending completion of conditions.

Eligibility: DWI Courts generally accept repeat DWI offenders with demonstrated substance abuse issues. Eligibility varies by judicial district. Conditional discharge is available only for first-time DWI offenders with no aggravating factors. Those charged with aggravated DWI (BAC ≥ 0.16%) may be eligible depending on the jurisdiction.

How Long a DUI Stays on Your Record

A DWI conviction remains on your New Mexico criminal record permanently. New Mexico does not allow expungement of DWI convictions. However, the state enacted a record sealing law in 2024 that may apply to certain older misdemeanor DWI convictions after a waiting period. On your driving record (MVD), DWI convictions remain visible for at least 10 years and are accessible to law enforcement indefinitely. Because New Mexico uses a lifetime lookback, old DWI convictions always affect future sentencing.

Frequently Asked Questions

How long does a DWI stay on your record in New Mexico?

A DWI conviction remains on your New Mexico criminal record permanently. The state does not allow traditional expungement of DWI convictions. New Mexico's record sealing law (effective 2024) may allow sealing of some older misdemeanor DWI convictions after a waiting period, but this is limited. For the purposes of penalty enhancement, New Mexico uses a lifetime lookback — meaning any prior DWI conviction, no matter how old, will count toward escalating future charges.

Is a first DWI a felony in New Mexico?

No, a first DWI in New Mexico is a misdemeanor carrying up to 90 days in jail and up to $500 in fines for a standard offense. An aggravated first DWI (BAC ≥ 0.16%) is still a misdemeanor but carries a mandatory 48-hour jail minimum and up to $1,000 in fines. A DWI becomes a 4th-degree felony in New Mexico on the 4th offense.

What happens if you refuse a breathalyzer in New Mexico?

Refusing a chemical test in New Mexico results in a 1-year license revocation with no option for an IID license — meaning you cannot legally drive at all during the revocation period. This is actually more restrictive than the penalty for a failed test (where an IID license is available). The refusal can also be admitted as evidence against you in court. Law enforcement may obtain a warrant to compel a blood draw despite your refusal.

How many DWIs is a felony in New Mexico?

A fourth DWI is a 4th-degree felony in New Mexico. The state uses a lifetime lookback period, so all prior DWI convictions count regardless of how long ago they occurred. A felony DWI carries a mandatory 18-month prison sentence that cannot be suspended or deferred, plus fines up to $5,000 and lifetime license revocation (with petition for reinstatement after 5 years).

What is aggravated DWI in New Mexico?

Aggravated DWI applies when your BAC is 0.16% or higher. For a first offense, aggravated DWI adds a mandatory 48-hour jail minimum and increases the maximum fine to $1,000. It also requires mandatory community service. At all offense levels, aggravated DWI carries enhanced mandatory minimum jail sentences. The aggravated DWI charge is separate from and in addition to the standard DWI charge.

Do I need an ignition interlock device after a first DWI in New Mexico?

Yes, New Mexico mandates an ignition interlock device for all first-time DWI offenders. After your license is revoked, you can obtain an IID license that allows you to drive only vehicles equipped with an approved IID. The IID requirement lasts 1 year for a first offense. New Mexico was one of the first states to require IID for first offenders, and studies have shown this policy significantly reduces repeat DWI rates.

Can New Mexico seize your vehicle for DWI?

Yes, New Mexico has vehicle seizure and forfeiture provisions for DWI offenses. A vehicle can be seized upon arrest for a second or subsequent DWI if the driver's license is already revoked for a prior DWI. For felony DWI (4th or subsequent), vehicle forfeiture is mandatory. The forfeited vehicle becomes property of the state. The vehicle owner may contest the forfeiture in court, but the burden is on the owner to prove the vehicle was not used in a DWI offense.

Do I need an SR-22 after a DWI in New Mexico?

Yes, New Mexico requires an SR-22 certificate of financial responsibility for license reinstatement after a DWI. You must maintain SR-22 insurance for a minimum of 3 years. The SR-22 requirement runs concurrently with the IID requirement. If your insurance lapses during the SR-22 period, the MVD will re-revoke your license.
