Arizona First-DUI Jail Time and Evidence-Based Psychotherapy

If you are facing a first-offense DUI in Arizona, one of the first questions is almost always about jail. Arizona law sets a minimum jail term for a standard first DUI, but it also describes a pathway that can allow a judge to suspend most of that time when certain court-ordered programs are completed.

Current Arizona law also defines who may provide “evidence-based psychotherapy” for DUI sentencing purposes. As of September 12, 2026, that list includes more licensed professionals than it did before (HB 2573 / Laws 2026, Ch. 99).

This guide walks through what the statutes say in plain English, without promising any particular outcome.

The basic first-DUI jail rule

Under A.R.S. § 28-1381, a person convicted of a standard (non-extreme, non-aggravated) DUI is generally guilty of a class 1 misdemeanor. Among other penalties, the statute provides that the person:

• Must be sentenced to serve not less than ten consecutive days in jail; and

• Is not eligible for probation or suspension of the sentence unless the entire sentence is served, except as the statute separately allows.

That “except” is the part most people ask about.

The one-day pathway (first offense)

A.R.S. § 28-1381(J) says that, notwithstanding the ten-day minimum, at sentencing the judge may suspend all but one day of the jail sentence if the person completes a court-ordered:

• alcohol or other drug screening,

• education,

• evidence-based psychotherapy or treatment program, or

• evidence-based psychotherapy.

If the person fails to complete what the court ordered and has not been placed on probation, the court is directed to issue an order to show cause about why the remaining jail time should not be served.

Important limits, in practical terms:

• This is a sentencing option for the judge, not an automatic right.

• The program must be court-ordered and completed as the court requires.

• A first DUI still carries other consequences (fines, assessments, possible ignition interlock, traffic survival school, and more) even when jail time is reduced.

Who can provide “evidence-based psychotherapy”

House Bill 2573 (Laws 2026, Chapter 99) amended several DUI statutes, including § 28-1381. It took effect on the Arizona Legislature’s general effective date of September 12, 2026.

The amended definition of “evidence-based psychotherapy” in § 28-1381(R) means psychotherapy that integrates the best available scientific research with clinical expertise in light of the patient’s characteristics, culture, and preferences, and that is offered by any of the following:

1. A psychologist licensed under Title 32, Chapter 19.1;

2. A behavioral health professional licensed under Title 32, Chapter 33 and authorized to engage in the practice of behavioral health; or

3. A health professional licensed in Arizona under Title 32 whose scope of practice authorizes independent psychotherapy, including a psychiatric nurse practitioner (Title 32, Chapter 15), a psychiatric physician assistant (Title 32, Chapter 25), and a psychiatrist (Title 32, Chapters 13 and 17).

Why this matters to clients: someone already seeing a qualifying psychiatrist, psychiatric NP/PA, or licensed behavioral-health clinician may be able to discuss with counsel and the court whether that care can count toward the court-ordered psychotherapy option, rather than assuming only a psychologist can fill that role. Eligibility still depends on the court’s orders, the provider’s license and scope, and the facts of the case.

Related DUI sections (§§ 28-1382, 28-1383, 28-1387, 28-1461, and 28-3319) were updated in the same bill so screening, education, treatment, and evidence-based psychotherapy language stays consistent across extreme and aggravated DUI contexts as well.

Second offenses: a different minimum (and a different suspension floor)

If, within an 84-month lookback window, a person has a second qualifying DUI conviction under § 28-1381 (or certain related convictions), the statute generally requires not less than ninety days in jail, with thirty days served consecutively.

In that setting, § 28-1381(L) allows the judge, at sentencing, to suspend all but thirty days if the person completes the court-ordered screening, education, evidence-based psychotherapy or treatment program, or evidence-based psychotherapy.

Repeat and aggravated DUI cases involve higher stakes. Do not treat a first-offense pathway as a template for every charge.

Ignition interlock timing often tracks program completion

For many alcohol-related DUI convictions, Arizona law also requires a certified ignition interlock device. Under A.R.S. § 28-3319(F) (as amended by HB 2573), the interlock requirement period generally begins on the date the person successfully completes the alcohol or other drug screening, education or treatment program, or evidence-based psychotherapy requirements of Title 28, and is otherwise eligible to reinstate driving privileges.

In other words, finishing the court-ordered program can affect both jail-suspension eligibility and when the interlock clock starts. That is one reason counsel often coordinates sentencing strategy with treatment timing and MVD/driver-license issues.

Practical questions to bring to a lawyer

Every case is different, but people often ask:

• Am I charged under § 28-1381, extreme DUI (§ 28-1382), or aggravated DUI (§ 28-1383)?

• Has the court ordered screening, education, treatment, or evidence-based psychotherapy, and which providers qualify for my order?

• If I already have a treating clinician, does that person’s Arizona license and scope fit the statute?

• How do jail, interlock, license suspension/revocation, and probation interact in my county court?

• Should I complete any program before sentencing, or only as the court orders?
