Aggravated DWI is a step up from an ordinary DWI, and it comes with mandatory jail time that a judge cannot suspend. In New Mexico, a DWI is aggravated if your breath or blood alcohol level is .16 or higher, if you refused testing, or if you caused bodily injury to someone while driving impaired. Even a first aggravated DWI carries a mandatory 48 hours in jail. Call (505) 247-1973 now.
The 10-day clock. If you were arrested for DWI, you have only 10 days from the date of arrest to ask for an MVD hearing. Miss that deadline and the revocation of your license becomes automatic, no matter what happens in court. See how the MVD hearing works →
The word aggravated makes a DWI sound much worse, and in terms of penalties it is. But the label depends on specific facts, a certain breath reading, a refusal, or an injury, and every one of those facts can be challenged. A breath machine can be wrong. A refusal can be disputed. An injury claim can be overstated. Whether your DWI is aggravated at all is often a real fight.
What Makes a DWI Aggravated
New Mexico law. A DWI is aggravated when any one of these is true:
- Your breath or blood alcohol concentration is .16 or higher, twice the ordinary legal limit.
- You refused a chemical breath or blood test after a lawful arrest.
- You caused bodily injury to another person as a result of driving while impaired.
A first aggravated DWI adds a mandatory 48 consecutive hours in jail that cannot be suspended.
The Added Jail Time
Aggravated DWI stacks mandatory jail on top of the regular DWI penalties for each offense level. A first aggravated DWI carries a mandatory minimum of 48 hours. On a second or third aggravated DWI, additional mandatory time is added to the already higher minimums for those offenses. The rest of the DWI consequences, fines, license revocation, probation, DWI school, and the ignition interlock, still apply on top.

Maybe the officer told you your breath test was high, and now the paperwork says aggravated. Maybe you said no to the test because you were scared or confused, and that refusal is being used to bump up the charge. Maybe there was a minor accident and someone claimed to be hurt. You feel like the deck is stacked, and the word mandatory has you terrified of jail.
Here is the truth: aggravated DWI depends on facts that can be wrong or challenged, and Mr. Nieto knows exactly where to look.
Why the Aggravating Facts Can Be Fought
Each path to aggravation has a weak point:
- The .16 reading depends on a breath machine that must be certified, calibrated, and operated correctly, after a proper observation period. Errors happen. See field and breath tests.
- A refusal only counts if the arrest was lawful and you were properly advised of the consequences. A confused or conditional response is not always a refusal. See test refusal.
- An injury must actually be connected to your impaired driving, and the severity is sometimes overstated.
Knock out the aggravating fact, and the mandatory jail that comes with it can fall away.
How Mr. Nieto Defends Aggravated DWI
Mr. Nieto defends the DWI itself and separately attacks the aggravating fact. He challenges the stop, the arrest, the field tests, and the breath or blood evidence, and he digs into whether the .16 reading, the refusal, or the injury holds up. Getting the charge reduced from aggravated to a standard DWI removes the mandatory jail and changes the whole negotiation. And because a DWI cannot be expunged in New Mexico, keeping this charge from sticking is worth every effort.
