DUI lawyers in Arizona (AZ)
Arizona charges drunk driving as DUI — driving under the influence. You will also see it written Extreme DUI or Super Extreme DUI: neighboring states use their own labels for the same conduct, and search results mix them freely. 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.
Arizona calls it DUI, not DUI
DUI stands for driving under the influence. That is the term on the charge sheet and the one Arizona attorneys use, so a search for «DUI lawyer» here returns firms doing the same work under a different name.
Arizona splits the charge by reading, and the interlock term goes up with it. Extreme DUI covers 0.15 to under 0.20 and carries 12 months on the device; Super Extreme DUI starts at 0.20 and carries 18 months on a first conviction, 24 on a second within seven years. Both bring mandatory jail that cannot be suspended — 30 days and 45 days respectively (A.R.S. 28-1382).
The consequences Arizona sets by statute
These are not negotiable with a prosecutor — they follow the conviction. Knowing them is how you judge whether fighting the charge is worth it.
- Interlock term: At least 12 months on a standard first conviction; longer at higher readings — 12 months for Extreme DUI at 0.15%, 18 months for Super Extreme at 0.20% (A.R.S. 28-1382)
- Lockout threshold: 0.020% — the engine will not start at or above that reading
- Program run by: Arizona MVD (Department of Transportation)
What each step carries in Arizona: second offense penalties in Arizona, first offense penalties in Arizona and when it becomes a felony penalties in Arizona.

How common drunk driving cases are in Arizona
Federal crash records give the backdrop to how Arizona writes and enforces its DUI law. Read the share with care: it depends heavily on how often police obtain an alcohol test, and that varies enormously between states.
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. Counts crashes where police recorded a drinking driver — narrower than the federal 0.08 BAC measure, so the real figure is higher.
What happens, and when
Exact windows are set by Arizona law — confirm yours with an attorney licensed there, because the first one is short.
The administrative clock starts immediately
Separate from any criminal charge, the licensing agency in most states starts its own process to suspend your license. You normally have a short window — in some states as little as seven days — to request a hearing. Miss it and the suspension proceeds regardless of what happens in court. This deadline is the single most common thing people lose by waiting.
Your first court appearance
The arraignment is where the charge is read and a plea is entered. It is usually short. What matters is what has been prepared before it — whether the stop, the testing procedure and the calibration records have been examined.
Evidence and negotiation
Breath and blood testing depends on equipment being maintained and procedures being followed. Records of both are obtainable. Most cases resolve at this stage rather than at trial.
Resolution and what follows
Beyond any fine or jail exposure, a conviction usually brings an interlock requirement, higher insurance through an SR-22 filing, and a record that follows you. The license side and the criminal side are resolved separately, and finishing one does not finish the other.
The AZ counties that see the most of these
Cases are heard where the stop happened, and volume shapes local practice: a county that handles hundreds of these has settled routines, diversion programs and known judges. A quiet one may have none of that.
These five counties account for 83% of every alcohol-involved fatal crash in Arizona, so the state’s caseload is concentrated in a handful of courthouses and local practice varies sharply between them. Statewide the figure is 19% against 26% nationally, but that gap is not what it looks like: Arizona police obtained an alcohol test for 25% of drivers in fatal crashes, against 40% nationally. Across all 51 jurisdictions the two move together closely — states that test more, record more. Comparing states on this number measures testing practice at least as much as drinking.

Finding a DUI lawyer near you in Arizona
«Near me» matters more here than in most legal work, and not for convenience. The prosecutor, the diversion program and the judge are all county level, so an attorney who works that courthouse weekly knows things that do not transfer from the next county over.
Distance to the courthouse matters less than how often the attorney appears in it. A firm two hours away that regularly handles AZ DUI cases in your county is a better bet than the nearest office that rarely does.
What «best» can and cannot mean
We do not publish a top list, do not rank firms and do not call anyone recommended — anyone who does is selling placement, and star reviews on legal directories are easy to buy. An affordable attorney who rarely fights this charge is not the bargain it looks like. What you can check yourself: whether they are licensed and in good standing with the Arizonabar, how much of their practice is DUI work rather than general criminal defense, and whether they appear in your county specifically.

What Arizona does about the device
Whatever happens in court, the licensing side ends the same way for most people: an interlock as the condition of driving again. Arizona sets its own trigger, its own length and its own list of companies allowed to fit it.
Arizona is one of the few states that publishes what a provider may charge, so the quote is checkable against the regulation rather than against another quote. See the Arizona figures and centers →
Before paying anyone, check the company against the state’s own register: Arizona Department of Transportation, MVD — provider, phone and the exact device model each one is authorized to fit. An installation by a company that is not on it does not count towards your term.
Cities in Arizona
DUI cases are heard in the county where the stop happened, so local practice matters. These are the Arizona cities we cover.
Injured in a Arizona drunk driving accident?
Then you need the opposite of this page: a AZ drunk driving accident lawyer, that is a personal injury attorney, who acts against the driver rather than for them.
Attorney advertising. InterlockDeviceNearMe is not a law firm, does not practice law, and does not give legal advice. Nothing here creates an attorney-client relationship. Requesting a consultation connects you with an independent attorney or a legal referral service, who decide separately whether to take your case. Case outcomes depend on facts we do not know, and no result is ever promised. Deadlines in DUI cases are short and vary by state — speak to a licensed attorney in your state before relying on anything you read here.
