A first DUI in New Mexico: what it can result in

An ordinary first DWI in New Mexico carries no mandatory custody: up to ninety days or a fine of up to $500 or both, with probation of up to a year if the sentence is suspended or deferred. What is mandatory is not jail but work — at least twenty-four hours of community service, a screening programme, and the driver rehabilitation course the statute itself calls DWI school. The picture changes on an aggravated DWI, which the section defines three ways: an alcohol concentration of sixteen one-hundredths or more within three hours of driving, causing bodily injury, or refusing chemical testing where the court finds on the evidence that the driver was under the influence. That carries not less than forty-eight consecutive hours in jail, and the statute says plainly that this time may not be suspended, deferred or taken under advisement. The same forty-eight hours attaches to failing to finish the community service, screening, treatment or DWI school. A deferred sentence still counts as a first conviction when a later offence is counted.

Start from what the statute forces and what it leaves to the judge. The floor here is up to 90 days; not less than 48 consecutive hours on an aggravated first offence, and it moves on the facts: aggravated dwi: 0.16 or more, bodily injury, or a refusal means a mandatory jail term that cannot be suspended or deferred. Everything above that floor is argued, and the same conviction can end up served in custody, on work release or as a condition of probation depending on the county and the judge. What no one can promise you is a sentence below the statutory minimum — that is not a question of persuasion.

Misdemeanor: up to 90 days; not less than 48 consecutive hours on an aggravated first offence, and a fine of up to $500, plus a $300 fine the court may add. The range is set by N.M. Stat. § 66-8-102(D), (E), (L), and the figures on this page come from the statute rather than from a summary of it.

Aggravated DWI: 0.16 or more, bodily injury, or a refusal — a mandatory jail term that cannot be suspended or deferred.

New Mexico requires an interlock license after every DWI conviction, first offense included — the MVD says so in as many words. The state also runs a legislatively mandated Indigent Fund, paid for by fees charged to convicted drivers, which helps eligible offenders with the cost of installing, leasing and removing the device. The device requirement and the criminal penalty are separate tracks: one is handled by the court, the other by New Mexico Motor Vehicle Division.
