Case Result — Mesa Municipal Court
Second Offense Super Extreme DUI (ARS 28-1382) • 0.20% BAC
Mandatory Minimum: 180 Days Jail → 4 Days Jail
Prior conviction struck. Case reduced to first offense. Client home for his newborn child.
If you are facing a second offense Super Extreme DUI in Arizona — especially one that involves an out-of-state prior conviction — the mandatory minimum sentence can feel crushing. This case study explains exactly how Phoenix DUI attorney Gordon Thompson reduced a 180-day mandatory jail sentence to just 4 days for a client in Mesa Municipal Court, and what legal strategies made that result possible.
The Case: Second Offense Super Extreme DUI, ARS 28-1382 (.20% or Above)
Client S.N. came to Gordon Thompson facing a second offense Super Extreme DUI charge in Mesa Municipal Court under ARS 28-1382(A)(2), with a recorded blood alcohol concentration (BAC) of 0.20% or above. Under Arizona law, this carries a mandatory minimum sentence of 180 days in jail.
Adding to the stakes:
- COVID-19 had eliminated work release at the time, meaning any jail time would be served without the ability to go to work.
- A judge could have substituted 36 days in jail plus 144 days on home detention — but that option was also at risk (explained below).
- The client’s wife had just had a newborn baby. A 180-day incarceration would have left the family without any income or support.
Why Home Detention Was at Risk: Prior Manslaughter Conviction
Under Arizona law, home detention is not available to defendants with a prior violent offense. S.N. had a prior manslaughter conviction on his record — a disqualifying factor that gave the sentencing judge grounds to deny home detention entirely. Without that alternative, the client could have faced the full 180 days in custody, with no work release and no ability to support his newborn and spouse.
This made it critical to address the second issue in the case: whether the out-of-state DUI conviction could legally be counted as a prior offense in Arizona at all.
Arizona’s Elements Test for Out-of-State DUI Prior Convictions
Arizona does not automatically treat every out-of-state DUI conviction as a “prior DUI” for sentencing purposes. The controlling legal standard is the elements test: an out-of-state conviction counts as a prior only if the conduct that violated the other state’s law would also have violated Arizona’s DUI law if it had occurred in Arizona.
In practical terms: if there is any way someone could have violated the other state’s DUI statute without violating Arizona’s DUI statute, then the out-of-state conviction is not a valid prior for Arizona sentencing purposes.
Gordon Thompson’s 47 years of experience handling Arizona DUI cases — including cases involving out-of-state DUI prior convictions — positioned him to spot exactly this kind of argument.
The Winning Argument: Definition of “Vehicle” in Arizona vs. the Prior State
After analyzing the other state’s DUI statute, Thompson identified a critical difference: the other state’s definition of “vehicle” included bicycles, meaning a person could receive a DUI for riding a bicycle while impaired under that state’s law.
Arizona law does not include bicycles in its definition of “vehicle” for DUI purposes. This means a person could have violated the other state’s DUI statute (by riding a bicycle while impaired) without having committed any DUI offense under Arizona law.
Thompson filed a motion to strike the prior conviction, arguing it did not satisfy Arizona’s elements test and therefore could not be used to elevate S.N.’s charge to a second offense.
After hearing arguments from both sides, the judge granted the motion.
Case Outcome: 4 Days in Jail Instead of 180
With the prior conviction struck, the case was treated as a first offense Super Extreme DUI. S.N. pleaded guilty to a first offense 0.20% Super Extreme DUI and received:
- 4 days in jail (vs. the 180-day mandatory minimum he faced)
- 15 days on home detention
Although the prior manslaughter conviction could have disqualified S.N. from home detention, the State did not object to it — and the client received home detention as part of the sentence. He was home with his wife and newborn child.
The difference between the worst-case outcome and the actual result: 176 days of freedom.
Why Experienced Arizona DUI Representation Matters
This case illustrates that challenging a second offense DUI in Arizona is not simply about contesting the traffic stop or the breath test. In cases involving out-of-state prior convictions, the outcome can turn entirely on a careful statutory comparison between Arizona law and another state’s DUI statute — a comparison that requires both legal knowledge and courtroom experience to execute effectively.
Very few attorneys will examine the specific definition of “vehicle” in another state’s code, compare it element-by-element with Arizona’s statute, and file a motion on that basis. Gordon Thompson has been doing exactly this kind of work for 47 years as a DUI and criminal defense attorney in Phoenix, Arizona.
Frequently Asked Questions: Second Offense Super Extreme DUI in Arizona
What is the mandatory minimum sentence for a second offense Super Extreme DUI in Arizona?
Under ARS 28-1382, a second offense Super Extreme DUI (BAC of 0.20% or above within 84 months of a prior DUI) carries a mandatory minimum of 180 days in jail. Arizona law permits a judge to substitute 36 consecutive days in jail plus 144 days on home detention — but home detention can be denied if the defendant has a prior violent conviction. Fines, fees, and assessments typically total several thousand dollars, and a two-year ignition interlock device requirement also applies.
Can an out-of-state DUI conviction count as a “prior” in Arizona?
Only if it passes Arizona’s elements test. An out-of-state DUI conviction qualifies as a prior in Arizona only if the conduct that violated the other state’s law would also have violated Arizona’s DUI law. If the other state’s statute is broader than Arizona’s — for example, if it covers vehicles or situations that Arizona’s law does not — an experienced DUI attorney can file a motion to strike that prior conviction.
How does the definition of “vehicle” affect an Arizona DUI prior conviction challenge?
Arizona’s DUI statutes do not include bicycles in the definition of “vehicle.” Some other states do. If a client’s out-of-state prior DUI could have been committed on a bicycle — conduct that would not constitute a DUI in Arizona — that prior may be legally invalid for Arizona sentencing purposes. Identifying this discrepancy requires a detailed comparison of both states’ statutes and the filing of a motion to strike the prior conviction in court.
Who qualifies for home detention on an Arizona DUI sentence?
Home detention allows a DUI defendant to serve part of their sentence at home with electronic monitoring while still being permitted to go to work. Under Arizona law, defendants with a prior violent offense are disqualified from home detention — the sentencing judge may deny it in those cases. However, if the State does not object to home detention even when a defendant is technically disqualified, a court may still impose it. Every case is different, and the outcome depends heavily on how the defense presents the issue.
What is the difference between a first and second offense Super Extreme DUI in Arizona?
A first offense Super Extreme DUI (BAC 0.20%+) carries a mandatory minimum of 45 days in jail, with an option to substitute a reduced jail term plus home detention. A second offense within 84 months dramatically increases the mandatory minimum to 180 days in jail, with 36 days minimum before any home detention can begin. Fines and ignition interlock requirements are also more severe on a second offense. Successfully challenging whether a prior conviction qualifies under Arizona law can be the difference between these two sentencing tiers.
How can a Phoenix or Mesa DUI attorney reduce a second offense Super Extreme DUI sentence?
An experienced Arizona DUI attorney can pursue several strategies, including: challenging whether an out-of-state prior conviction satisfies the Arizona elements test; filing motions to strike an invalid prior; negotiating with the State on sentencing alternatives such as home detention; and identifying statutory or procedural arguments that reduce mandatory minimum exposure. The right approach depends on the specific facts of each case — which is why experience with Arizona DUI statutes, case law, and local court procedures matters enormously.
