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.
Official term: DWI/DUI (both used)
BAC Limits
| Driver Type | BAC Limit |
|---|---|
| Standard (21+) | 0.08% |
| Commercial (CDL) | 0.04% |
| Under 21 | 0.02% |
| Enhanced Penalty | 0.16% — aggravated DWI (also triggered by refusing a test, causing bodily injury, or driving while revoked for DWI — 66-8-102D), which adds mandatory consecutive jail at every offense level |
Penalties by Offense
| Offense | Classification | Jail Time | Fines | License Suspension | IID |
|---|---|---|---|---|---|
| 1st Offense | Misdemeanor | Up to 90 days; no mandatory minimum for a standard first offense (66-8-102F). Aggravated DWI — BAC ≥ 0.16%, refusing a chemical test, causing bodily injury, or driving while revoked for a prior DWI (66-8-102D) — adds a mandatory consecutive 48-hour jail term. | Up to $500 for standard. Aggravated: up to $1,000. Plus screening fees, IID costs, and other assessments. | Administrative revocation by MVD: 6 months for a first failed test (age 21+, 66-8-111C) or 1 year for a first refusal (66-8-111B). A separate 1-year revocation follows a criminal conviction (66-5-29A(2)). An ignition interlock license (66-5-503) allows driving during the revocation period. | Mandatory for all first offenders — IID license issued for 1 year, allowing driving only with IID-equipped vehicle |
| 2nd Offense | Misdemeanor | Mandatory minimum 96 consecutive hours (4 days) up to 364 days (66-8-102F(1)). Aggravated DWI adds a separate consecutive 96-hour jail term on top of the standard minimum — a total mandatory minimum of 192 hours (8 days); neither term can be suspended or deferred. | Up to $1,000 plus assessments and screening fees | 2-year revocation upon conviction (66-5-29A(3)); the administrative revocation for a second failed test or refusal is 1 year. An ignition interlock license (66-5-503) allows driving during the revocation. | Mandatory for 2 years; IID license available to allow driving |
| 3rd Offense | Misdemeanor (still misdemeanor in NM; 4th is felony) | Mandatory minimum 30 consecutive days up to 364 days (66-8-102F(2)). Aggravated DWI adds a separate consecutive 60-day jail term on top of the standard minimum — a total mandatory minimum of 90 days; neither term can be suspended or deferred. | Up to $1,000 plus assessments | 3-year revocation; IID license may be available after a waiting period | Mandatory for 3 years |
| Felony | 4th-degree Felony | 4th offense (4th-degree felony): 18 months, of which 6 months cannot be suspended, deferred, or taken under advisement (66-8-102G). Mandatory minimums escalate with offense number — 1 year for a 5th offense, 18 months for a 6th, 2 years for a 7th; an 8th or subsequent offense is a 2nd-degree felony with a 10-year mandatory minimum (up to 12 years). | Up to $5,000 plus assessments | Revocation forever, with an ignition interlock required for life (66-8-102N(4)). Five years from the date of conviction, and every 5 years thereafter, the offender may apply to the district court for removal of the interlock requirement and restoration of the license (66-8-102P); the court may grant this only for good cause shown. | Ignition interlock required for life (66-8-102N(4)), on all vehicles driven, regardless of any later restoration of driving privileges |
Felony threshold: 4th DWI offense (lifetime lookback — all prior DWI convictions count regardless of when they occurred). Lookback period: Lifetime — all prior DWI convictions count toward enhancement. New Mexico eliminated its lookback period; a 4th DWI is always a felony regardless of when prior offenses occurred..
Additional Penalty Details
| Offense | Community Service | Probation | DUI School |
|---|---|---|---|
| 1st Offense | Up to 48 hours of community service at court's discretion; mandatory 48 hours for aggravated first offense | Up to 1 year; mandatory DWI screening and compliance with recommended treatment | Mandatory DWI school (typically 18–36 hours) and a clinical screening/assessment; completion of recommended treatment program |
| 2nd Offense | 48 hours mandatory community service | Up to 2 years; mandatory DWI treatment program and compliance monitoring | Mandatory DWI education and treatment program (intensive outpatient or outpatient depending on clinical assessment) |
| 3rd Offense | 96 hours mandatory community service | Up to 3 years; intensive supervision and mandatory treatment | Mandatory intensive treatment program; residential treatment may be ordered |
| Felony | At court's discretion as parole condition | Up to 5 years post-incarceration supervised probation; mandatory treatment and monitoring | Mandatory intensive inpatient treatment program |
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 administrative revocation (66-8-111B). Subsequent refusals escalate: 2 years for a second, 3 years for a third, and lifetime for four or more refusals. An ignition interlock license (66-5-503) is available to drive during a refusal revocation — the MVD lists interlock license eligibility alongside the refusal revocation. Refusing the test also makes the offense aggravated DWI (66-8-102D), adding mandatory jail. Refusal can be introduced as evidence in court. The refusal revocation is separate from any DWI conviction revocation.
Aggravating Factors
| Factor | Impact |
|---|---|
| BAC of 0.16% or higher (Aggravated DWI) | Adds a separate mandatory consecutive jail term on top of the base minimum — 48 hours (first offense), 96 hours (second, for a 192-hour total minimum), or 60 days (third, for a 90-day total minimum); these added terms cannot be suspended, deferred, or taken under advisement (66-8-102D, F) |
| Refusal to submit to chemical testing | Escalating administrative revocation — 1 year for a first refusal, then 2 years, 3 years, and lifetime for four or more (66-8-111B); an IID license remains available during the revocation (66-5-503); refusal also constitutes aggravated DWI with added mandatory jail (66-8-102D) and is 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 prison term (6-month minimum for a 4th offense, escalating to a 10-year minimum by the 8th); 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
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.
