Statute
Mandatory minimums apply by statute
These are legislatively mandated — courts must impose them upon conviction regardless of the judge's individual assessment of the case.
DUI / DWI Defense
Mandatory Minimum Penalties for DUI
New Mexico law imposes mandatory minimum penalties for DUI convictions. These minimums apply regardless of circumstances and limit a judge's ability to reduce or suspend certain parts of a sentence. Understanding these requirements is critical when evaluating risk, negotiating a case, or deciding how to proceed.

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
Mandatory minimum DUI penalties limit judicial discretion and apply even in first-offense cases.
Mandatory minimum penalties are punishments the court must impose if a DUI conviction occurs. These penalties apply even when the facts are favorable or the offense is a first DUI. While some aspects of a sentence may be negotiable, mandatory minimums set a floor that cannot be avoided once a conviction is entered.
A mandatory minimum is the lowest sentence allowed by law for a specific offense. If a person is convicted of DUI, the court must impose at least the minimum punishment required, regardless of mitigating circumstances.
Mandatory minimum penalties apply after a DUI conviction, including: first-offense DUI; aggravated DUI; repeat DUI / DWI offenses; certain refusal-related cases.
If a case proceeds toward conviction, mandatory minimum penalties shape negotiations, plea options, and sentencing strategy. Avoiding or reducing mandatory minimum exposure is often a central focus of DUI defense.
Key points
Waiver
Judges cannot waive required penalties
Unlike discretionary sentencing, mandatory minimums are not subject to judicial mercy or reduction based on circumstances.
Aggravated
Aggravated DUI carries higher mandatory minimums
A BAC of 0.16 or higher, refusal of testing, or injury to another person elevates the mandatory minimum significantly.
Prior offenses
Penalties increase sharply with prior offenses
Each prior DUI or DWI conviction ratchets up the mandatory minimum — making a first-conviction record critical to manage.
Penalties & Requirements
What applies after a DUI conviction
Certain DUI convictions require mandatory jail or confinement time. The length increases with aggravating factors and prior convictions. In some cases, limited alternatives may be available, but mandatory time cannot be eliminated entirely.
Ignition interlock installation is mandatory for most DUI convictions. The length of the interlock requirement increases with offense level and applies independently of criminal court sentencing.
Mandatory minimum penalties often coincide with administrative license revocation or restriction through the Motor Vehicle Division (MVD). These proceedings occur separately from criminal court and carry their own mandatory timelines.
Mandatory fines and court costs apply to DUI convictions. These amounts increase with repeat offenses and aggravated charges and are separate from administrative fees.
Courts must order alcohol or substance abuse screening and treatment as part of sentencing. Completion is required and monitored as a condition of probation.
Mandatory probation conditions may include: regular reporting; compliance with treatment; abstaining from alcohol or drugs; compliance with all court and MVD orders.
How these penalties affect a case
Limited judicial discretion
Once a DUI conviction occurs, judges have limited authority to reduce mandatory penalties. Negotiation efforts typically focus on charge level, aggravation status, or alternative resolutions where legally available.
Mandatory minimums significantly affect plea discussions. Prosecutors and defense counsel must account for required penalties when evaluating resolutions.
A DUI conviction establishes a baseline for enhanced penalties in future cases. Mandatory minimums increase sharply with subsequent offenses.
Common Questions
Mandatory minimums — frequently asked
Quick answers to the questions we hear most often. Every case is different — call for a private consultation.
Can a judge give me less than the mandatory minimum?
No. Mandatory minimums are required by statute. A judge cannot sentence below the statutory floor, regardless of mitigating circumstances or the judge's personal assessment. Defense strategy must account for these floors when evaluating resolution options.
Do mandatory minimums apply even if it's my first DUI?
Yes. New Mexico imposes mandatory penalties on first-offense DUI convictions, including minimum jail or community service, fines, ignition interlock, and screening or treatment requirements. The mandatory minimums for a first offense are lower than for repeat offenses but cannot be waived if a conviction occurs.
What makes a DUI "aggravated" and how does it affect mandatory minimums?
A DUI is classified as aggravated if you had a BAC of 0.16 or higher, refused chemical testing, or caused bodily injury to another person. Aggravated DUI carries higher mandatory minimums across all categories — jail time, fines, interlock requirements, and probation periods. Avoiding an aggravated classification is often an important goal in plea negotiations.
Can I serve mandatory jail time through a community service program?
In some first-offense cases, limited alternatives to mandatory jail time may be available — such as community service in lieu of certain confinement requirements. These alternatives are fact-dependent, discretionary in some situations, and become less available with aggravated charges or prior offenses. An attorney can evaluate whether alternatives may apply to your case.
How do mandatory minimums affect plea negotiations?
Mandatory minimums set the floor below which any resolution cannot go. Negotiations typically focus on charge level (e.g., whether a DUI can be reduced to a lesser offense) and whether aggravation applies — both of which directly affect which mandatory minimums apply. Understanding the applicable minimums before any discussion is essential to evaluating any offer.
