An arrest for DWI in New Mexico sets two separate legal clocks running at the same time. One is the criminal case, which moves through district or magistrate court and can take months. The other is the administrative license revocation handled entirely by the Motor Vehicle Division, and it moves much faster, on its own schedule, regardless of what happens in the criminal case.
Under NMSA § 66-8-112, you have 10 days from receiving the Notice of Revocation to submit a written request for an MVD hearing. Those are two different numbers doing two different jobs: 10 days is the deadline to act, and 20 days is the point at which your license is automatically revoked if no timely request was filed. Missing the 10-day window does not just weaken your position, it typically ends it. Patrick J. Martinez has represented Albuquerque drivers at MVD hearings for over 25 years and files the request the day a client calls.
Refusing a breath or blood test after arrest triggers a different statute with its own, often longer, revocation period. See DWI Breath Test Refusal for how implied consent and refusal penalties work under New Mexico law.
The 10-Day Deadline Under NMSA § 66-8-112
The deadline to request an MVD hearing is 10 days, not 20. The arresting officer serves a Notice of Revocation at the time of arrest, and the clock on your written hearing request starts immediately. If that request is not received by the Motor Vehicle Division within 10 days, the automatic revocation takes effect 20 days after the date of arrest, whether or not the criminal DWI case has even gone to a first hearing.
Patrick's office treats this deadline as absolute because the statute treats it as absolute. A late request is not accepted the way a late filing sometimes can be in civil court. The safest move after any DWI arrest is to have the hearing request filed the same day, before the 10 days start to feel like plenty of time.
Already Facing a License Revocation Hearing?
You have 10 days from the Notice of Revocation to request your MVD hearing under NMSA § 66-8-112. Miss that window and your license is automatically revoked 20 days after arrest. Full details on the process, along with the request form, are on the firm's resources page.

The MVD hearing is a civil administrative proceeding, not a criminal trial, and it asks a narrower set of questions than your criminal case does. A hearing officer considers whether the officer had reasonable grounds to believe you were driving while impaired, whether you were lawfully arrested, and whether the chemical test (or your refusal of it) was handled according to the statute. Guilt or innocence on the DWI charge itself is not decided here.
Patrick represents clients at these hearings directly, cross-examining the arresting officer and challenging the paperwork the same way he would in court. Winning the hearing keeps your driving privileges intact while the criminal case proceeds. Losing the hearing means the revocation goes into effect, and depending on your record, an ignition interlock license may still be available to keep you driving under restriction. Either way, the hearing itself often produces sworn testimony from the officer that becomes useful later in the criminal case.
