A first DUI in Arizona: what it can result in

Verified · next review

Ten consecutive days, and no fine-only sentence exists. Arizona writes the floor into the sentence and closes the exit: you are not eligible for probation or suspension of the sentence unless the entire term is served. A reading of 0.15 moves you to the extreme division at 30 consecutive days, and 0.20 to 45 — those tiers are separate offenses, not enhancements of this one.

Written any number of ways — a 1st offense DUI, DUI 1st, DUI first offense AZ, or a first DUI in AZ — and the paperwork will use none of them. Arizona charges it under a section number, and that is what decides the range below.

What the statute sets

Grade. Class 1 misdemeanor

Confinement. Not less than 10 consecutive days

Fine. Not less than $250

The other half of the sentence

The device is a separate track

Arizona requires a certified device with a camera and GPS that reports every test to the MVD in real time. The clock starts when your license becomes eligible for reinstatement or when the MVD receives the conviction — whichever is later — so installing early does not shorten anything.

In Arizona the interlock term runs 12 months and is administered by Arizona MVD (Department of Transportation) — which is why a plea that settles the criminal case does not settle the device. What counts as a violation on it, and what an agency adds to the term, is its own arithmetic: violations and lockouts. Getting it off at the end is a procedure of its own too — removal and waivers.

Arizona DUI questions

Is jail time mandatory for a 1st DUI in Arizona?

Arizona writes the floor into the sentence and closes the exit: you are not eligible for probation or suspension of the sentence unless the entire term is served. A reading of 0.15 moves you to the extreme division at 30 consecutive days, and 0.20 to 45 — those tiers are separate offenses, not enhancements of this one.

How likely is jail time for a first DUI in AZ?

Start from what the statute forces and what it leaves to the judge. The floor here is not less than 10 consecutive days, and it moves on the facts: a reading of 0.15 or 0.20 means extreme and super extreme dui — 30 and 45 consecutive days. 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.

What is the punishment range for a 1st DUI in Arizona?

Class 1 misdemeanor: not less than 10 consecutive days, and a fine of not less than $250. The range is set by A.R.S. § 28-1381(I); § 28-1382(D), and the figures on this page come from the statute rather than from a summary of it.

What makes it worse in Arizona?

A reading of 0.15 or 0.20 — extreme and super extreme dui — 30 and 45 consecutive days.

Does an interlock come with it in Arizona?

Arizona requires a certified device with a camera and GPS that reports every test to the MVD in real time. The clock starts when your license becomes eligible for reinstatement or when the MVD receives the conviction — whichever is later — so installing early does not shorten anything. The device requirement and the criminal penalty are separate tracks: one is handled by the court, the other by Arizona MVD (Department of Transportation).

Other steps in Arizona: second offense penalties and when it becomes a felony penalties.
