Who this page is for

This page is for drivers charged in Gilbert or the East Valley, including people cited into Gilbert Municipal Court and people whose case may move into Maricopa County Superior Court. It also applies if you live nearby and the stop or arrest happened in or around Gilbert.

We focus on criminal defense only. We do not handle civil lawsuits, family matters, or business disputes.

First-time, extreme, and aggravated charges in plain Arizona terms

Arizona does not treat every driving under the influence case the same. Your citation or complaint controls what you face; the labels below are general.

Standard (often called a first-time or “regular”) driving under the influence. A typical alcohol-related charge can rest on impairment to the slightest degree, or on an alcohol concentration of 0.08 or higher within the time the statute describes. For many first offenses without extra aggravating facts, this is a class 1 misdemeanor. Jail minimums, fines, ignition interlock, and Motor Vehicle Division consequences can still apply.

Extreme driving under the influence. When the allegation is an alcohol concentration of 0.15 or higher (and related “super extreme” allegations at 0.20 or higher), Arizona uses a separate extreme-influence statute. These cases are often still misdemeanors on a first offense, but mandatory minimum jail ranges are higher than a standard first offense.

Aggravated driving under the influence. This is a felony path. Common triggers include driving under the influence while your license is suspended or revoked for a prior related reason, a third qualifying offense within the statute’s lookback window, a passenger under fifteen in the vehicle, driving while an ignition interlock is required, or driving the wrong way on a highway. Get advice early.

Drug-related impairment can also fall under these laws. Bring the full citation and any toxicology paperwork to your consultation.

Gilbert Municipal Court versus Superior Court

Many first-offense misdemeanor cases that start with a Gilbert stop are set in Gilbert Municipal Court, often where first appearances, disclosure, and negotiation happen.

Maricopa County Superior Court typically enters when the charge is a felony (including many aggravated cases) or when the matter is filed or transferred there. Pinal County filings follow Pinal’s courts. If you are unsure which courthouse is on your paperwork, call us with the citation and court date.

After a Gilbert arrest or citation

Criminal court and Motor Vehicle Division issues often run at the same time. At a high level:

1. Do not discuss the facts of the stop with police without a lawyer.

2. Keep every piece of paper: citation, release conditions, testing notices, and Motor Vehicle Division notices.

3. Calendar your court date and appear as required, or have counsel appear when allowed.

4. Watch separate license deadlines; Motor Vehicle Division processes run on their own clock.

5. Call before the first appearance when you can.

We will not promise that charges will be dismissed, reduced, or “beaten.” We will walk through what the State must prove and what options may exist in your court.

First-offense jail and evidence-based psychotherapy (House Bill 2573)

For some standard first-offense cases, Arizona law describes a sentencing path in which a judge may suspend most of a minimum jail term when court-ordered screening, education, treatment, or evidence-based psychotherapy is completed as ordered. House Bill 2573 (effective September 12, 2026) updated who may provide “evidence-based psychotherapy” for these purposes.

Eligibility is fact-specific and never automatic. Read our published guide, then confirm with counsel whether anything in it could apply to your charge:

Arizona First-DUI Jail Time and Evidence-Based Psychotherapy

That guide is general information. It is not a promise that you qualify for a one-day jail option or any other sentence.

How we approach a driving under the influence case

Brian Garner’s work typically includes reviewing the stop, field exercises, breath or blood testing, and camera video when it exists; checking whether the charge label matches the evidence; coordinating criminal court strategy with Motor Vehicle Division timing; preparing for negotiation when appropriate and for trial when it is not; and explaining options in plain English. Past results for other clients do not guarantee a similar outcome for you.

Frequently asked questions

Do you handle first-time driving under the influence cases in Gilbert? Yes. First-time and other misdemeanor allegations in Gilbert Municipal Court are a core part of the practice, along with extreme and aggravated filings.

What is extreme or aggravated driving under the influence in Arizona? Extreme usually refers to higher alcohol-concentration allegations (commonly 0.15 and above, with a separate higher tier at 0.20 and above). Aggravated driving under the influence is a felony path based on triggers such as a suspended license for a prior related reason, repeat offenses within the lookback window, a young passenger, an interlock requirement, or wrong-way driving. Your complaint controls which statute you face.

Will I lose my license? Driving privileges and Motor Vehicle Division actions often run beside the criminal case. Whether and how long you lose privileges depends on the charge, your record, testing decisions, and Motor Vehicle Division rules. Bring every notice you received.

Can a first offense qualify for the one-day jail / treatment path? Sometimes the statutes allow a judge to suspend most of a minimum jail term after court-ordered programs, including evidence-based psychotherapy under the updated rules. That is not automatic. See our first-offense guide and ask us to check your paperwork.

Do you appear in Gilbert Municipal Court? Yes. We also handle matters in other Maricopa County and Pinal County courts when the case belongs there.
