A first DUI has a particular kind of dread to it: you’ve never been in the system, you don’t know what’s serious and what’s routine, and the paperwork you were handed makes it sound like you can just wait for a court date. You can’t — one of your two deadlines is already running. The good news for a genuine first offender is that Arizona’s mandatory penalties, while real, are more manageable than the worst-case numbers online suggest, and first DUIs are among the most defensible cases there are. Here’s the honest version of what you’re facing.
The 15-day clock is the part people miss. Separate from court, the MVD moves to suspend your license after a DUI arrest, and you generally have about 15 days from the arrest to request the hearing that contests it. Miss it and the suspension takes effect automatically — even if your court case later goes well. Handle this first.

What a first standard DUI actually carries
For a first offense under A.R.S. § 28-1381 with a BAC in the standard range (0.08–0.149), the statutory minimums are:
- Jail: a minimum of 10 consecutive days — but a court may suspend up to 9 of them if you complete alcohol screening and any recommended education or treatment. In practice, many first offenders serve close to the minimum after completing the required program.
- Fines: not less than $1,250 before surcharges and assessments (real totals run higher once those and program costs are added).
- License: a 90-day suspension, with a restricted permit often available part-way through.
- Ignition interlock: a certified device on your vehicle for a minimum of a year.
- Alcohol screening and up to five years of probation.
Those are the standard-tier numbers. If your BAC was 0.15 or higher, you’re in Extreme (30-day minimum) or Super Extreme (45-day minimum) territory — see the main DUI guide for those tiers. And the whole framework was updated effective September 26, 2025, which, among other changes, now lets evidence-based psychotherapy count toward the treatment condition for getting your license back.
The two cases you’re actually fighting
A first DUI creates two separate proceedings, and confusing them is the classic first-timer mistake:
- The criminal case — in Flagstaff Municipal Court (if the stop was in city limits) or a Coconino County justice court — decides guilt, jail, fines, and probation. It moves on the court’s calendar, over weeks to months.
- The MVD case — a completely separate administrative track that decides your license, on that 15-day clock. You can win or resolve the court case and still lose your license for months if no one requested the MVD hearing in time.
What it costs — the honest total
The fine is only part of it. Between the base fine, jail costs, screening and any required classes, the ignition interlock installation and monthly lease, higher insurance, and attorney fees, a first DUI commonly runs several thousand dollars all in. That’s a real number worth knowing up front — and part of why fighting to reduce or dismiss the charge, where the facts allow, can pay for itself.
Why a first offense is often defensible
“Mandatory” penalties only apply if there’s a conviction — and first DUIs frequently have soft spots:
- The stop. No lawful reason to pull you over can mean the whole case is suppressible.
- Field sobriety tests, which are unreliable to begin with and even less reliable at Flagstaff’s 7,000-foot elevation, on cold, uneven roadsides.
- The breath or blood test — calibration, maintenance, the 20-minute observation period, chain of custody, and lab procedure all have to hold.
- The math. The two-hour window and rising-BAC science sometimes don’t support the state’s number.
Even when a dismissal isn’t realistic, first offenses are the cases most often reduced — for example to reckless driving, which lands in traffic-violation territory instead — sidestepping the mandatory DUI sentencing scheme. The point of an early review is to find out which of these applies to you before you make any decision.
Two situations change this analysis and have their own guides: if marijuana rather than alcohol was involved, see marijuana DUI in Arizona, and if you’re under 21, the zero-tolerance rules apply on top of everything here. A DUI is also a criminal charge — our Flagstaff criminal defense overview covers how these cases move through the local courts.
What to do in your first week
- Find the MVD/admin-per-se paperwork from your arrest and note the deadline. This is the time-sensitive one.
- Don’t discuss the case with anyone but a lawyer — not the officer’s follow-up, not social media.
- Write down everything while it’s fresh: where you were, what and when you drank, what tests were done and at what time.
- Don’t drive on a suspended license — doing so can turn a misdemeanor first DUI into a felony aggravated DUI.
- Get the arrest reviewed before your first court date, even if you think you’ll just plead.
Frequently asked questions
Will I actually go to jail for a first DUI?
Arizona requires a minimum jail term, but for a standard first offense up to 9 of the 10 days can be suspended when you complete alcohol screening and any recommended program — so many first offenders serve close to the minimum. Extreme (0.15+) and Super Extreme (0.20+) offenses carry longer minimums that are harder to reduce.
What’s the 15-day deadline I keep seeing?
It’s the MVD administrative case, separate from court. You generally have about 15 days from the arrest to request a hearing that pauses and contests the license suspension. Miss it and the suspension is automatic. It’s the single most common thing first-timers lose by waiting.
Can a first DUI be dismissed or reduced?
Sometimes dismissed (for example, if the stop was unlawful or the test evidence is thrown out), and fairly often reduced to a lesser charge like reckless driving, which avoids the mandatory DUI penalties. Whether either is realistic depends entirely on the facts of your stop and testing.
How much will a first DUI cost me?
More than the fine. Between the $1,250-plus fine, jail costs, screening and classes, the ignition interlock, insurance increases, and attorney fees, a first DUI commonly runs several thousand dollars total.
Do I need a lawyer for a first offense?
At minimum, get the free consultation before you decide anything. A lawyer can protect the MVD hearing, review the stop and testing for defenses, and tell you honestly whether fighting or resolving the case makes sense — a short delay to do that forecloses nothing.
Will a first DUI stay on my record forever?
Arizona doesn’t expunge DUI convictions, but it does allow many to be “set aside” under A.R.S. § 13-905 after you complete the sentence — which formally notes the judgment was vacated and can help on background checks, though it isn’t a full erasure. Keeping the conviction off your record in the first place (through a dismissal or a reduction to a non-DUI charge) is a stronger outcome where the facts allow it, which is one more reason the early review matters.
How long will the whole thing take?
The MVD license track moves on its own short timeline, while the criminal case can run anywhere from a few weeks to several months — longer if there are pretrial motions to suppress evidence. A quick guilty plea is the fastest path but also the one that locks in every mandatory penalty, so “getting it over with” and “getting the best outcome” are usually not the same thing.
