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.
Grade. Class 1 misdemeanor
Confinement. Not less than 10 consecutive days
Fine. Not less than $250

What turns this DUI into something worse
Each line below is a separate provision with its own punishment range. They stack with the arithmetic of prior convictions rather than replacing it.
| The fact | What it makes it | Detail and source |
|---|---|---|
| A reading of 0.15 or 0.20 | Extreme and super extreme DUI — 30 and 45 consecutive days | These are separate offenses under their own section rather than enhancements. On a first conviction the floors are 30 and 45 consecutive days; a judge may suspend all but nine days, or all but fourteen at the higher tier, if you fit an interlock for twelve months.

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.
