New Mexico DWI Penalties: Fines, Jail Time, and What the Court Actually Imposes
What a First-Offense DWI Actually Costs You in Court
A first-offense DWI in New Mexico is prosecuted as a misdemeanor under NMSA 1978 § 66-8-102. The penalties the court can impose depend entirely on one thing: whether your charge is classified as a standard DWI or an aggravated DWI.
For a standard first offense — meaning your blood alcohol concentration (BAC) tested between 0.08% and 0.15% — the statutory maximum is 90 days in jail and a $500 fine. But here's the part most people miss: there is no mandatory minimum jail time for a standard first offense. The court can suspend the entire jail sentence, and in practice, most judges do exactly that for drivers who enter the First Offender Program.
For a driver placed in the First Offender Program, the required conditions include 24 hours of community service, a 12-hour DWI school, a substance abuse screening, attendance at a MADD Victim Impact Panel, one year of supervised probation, and one year with an ignition interlock device.
Standard vs. Aggravated: The Line That Changes Everything
The moment your BAC hits 0.16% or higher, New Mexico reclassifies the offense as an aggravated DWI. The same reclassification can apply if you refused the chemical test and the state presents evidence of intoxication at trial, or if the incident caused bodily injury to another person.
| Penalty | Standard First-Offense DWI | Aggravated First-Offense DWI |
|---|---|---|
| Maximum jail time | 90 days | 90 days |
| Mandatory minimum jail | None (can be suspended) | 48 consecutive hours (cannot be suspended) |
| Statutory fine | $300 standard, up to $500 maximum | $300 standard, up to $500 maximum |
| Community service | 24 hours minimum | 24–48 hours minimum |
| Supervised probation | Up to 1 year | Up to 1 year |
| Ignition interlock | 1 year mandatory | 1 year mandatory |
| License revocation (MVD) | 6 months (BAC fail) | 6 months (BAC fail); 1 year (test refusal) |
That 48-hour mandatory minimum for aggravated DWI is non-negotiable — the judge cannot defer it, suspend it, or convert it to community service. It is consecutive jail time, meaning you serve two full days.
The Fines and Fees Nobody Warns You About
The $300 standard fine, up to the $500 maximum, is the smallest piece of the financial hit. New Mexico layers mandatory court fees on top that most drivers do not see coming until sentencing.
In Bernalillo County Metropolitan Court, the total mandatory fee assessment runs approximately $377. That figure includes a $65 Crime Lab Fee, a $75 Community DWI Fee, a $10–$20 Corrections Fee, a $10 Court Automation Fee, a $3 Traffic Safety Fee, a $3 Judicial Education Fee, a $5 Jury and Witness Fee, a $5 Brain Injury Fee, and a $10–$24 Court Facilities Fee. Other courts across the state assess similar fee structures, though the exact breakdown varies by jurisdiction.
Combined with the statutory fine, the court-imposed financial penalties alone run $677 to $877 before you factor in the cost of the ignition interlock device, insurance increases, or attorney fees.

Community Service and Treatment Requirements
Every first-offense DWI conviction requires a minimum of 24 hours of community service. For an aggravated offense, the court can impose up to 48 hours. These hours must be completed through an approved organization and documented for the probation officer.
The court also orders a substance abuse screening through the Impaired Driving Assessment (IDA). Based on the results, you may be required to complete outpatient counseling, an intensive treatment program, or both. This is in addition to the mandatory 12-hour DWI school and the MADD Victim Impact Panel — both must be completed as conditions of probation.
What Happens When You Complete Everything
If you complete the First Offender Program — meaning you fulfill every condition of your deferred sentence over the one-year probation period — the court enters a formal dismissal of the criminal charges. Since the July 2026 C.T. ruling by the New Mexico Court of Appeals, drivers who receive this dismissal may be eligible to petition for expungement of the arrest record after one additional year.
This path is only available through a deferred sentence that ends in dismissal. A straight guilty plea without a deferred sentence counts as a conviction and remains permanently ineligible for expungement under NMSA 1978 § 29-3A-5(G).
Planning Your Way Through the Process
The penalty structure for a New Mexico DWI is designed around compliance, not incarceration — especially for first offenders who qualify for the First Offender Program. The timeline runs roughly 12 to 18 months from arrest to full reinstatement of an unrestricted license.
The New Mexico First-Offense DUI Guide maps every step of that timeline: the administrative MVD track, the criminal court track, interlock licensing, and the reinstatement sequence. It breaks each requirement into the specific forms, fees, and deadlines you need to meet.
