Facing an underage DUI charge in Tempe can feel overwhelming. You may be wondering whether the charge will follow you permanently or whether a dismissal of underage DUI charges is even possible. The short answer is yes — dismissal is possible in certain situations, but outcomes depend heavily on the facts of each case.
Arizona takes underage drinking and driving very seriously. However, that does not mean every charge automatically leads to a conviction. Understanding how these cases work is the first step toward protecting your future.
This post explains how underage DUI laws work in Arizona, what factors can lead to a dismissal, and why working with an experienced criminal defense attorney matters so much at this stage.
How Arizona’s Underage DUI Laws Work
A.R.S. § 4-244(34) prohibits a person under 21 from driving or being in physical control of a motor vehicle while any spirituous liquor is in the body. This is distinct from a separate DUI charge. Drivers aged 18 through 20 are not juveniles merely because they are below drinking age.
Separate DUI charges under § 28-1381 include impairment to the slightest degree as well as specified alcohol-concentration and drug provisions. A reading below 0.08 does not by itself rule out every DUI charge. Start with the exact statute on the citation.
What Charges Can a Minor Face?
Depending on the circumstances, an underage driver may face one or more of the following charges:
- Underage DUI (Zero Tolerance): Any detectable alcohol while driving under 21
- DUI under § 28-1381: Includes slightest-degree impairment and specified alcohol-concentration or drug allegations; not solely a 0.08 threshold.
- Extreme DUI: BAC of 0.15% or higher
- Minor in Possession (MIP): A separate charge sometimes filed alongside a DUI
Whether the stop occurred near Mill Avenue, Arizona State University or elsewhere in Tempe, preserve its exact location and circumstances. The neighborhood alone does not establish the lawful basis for the stop or which offense can be proved.
Is Dismissal of Underage DUI Charges Actually Possible?
Yes, dismissal is a real outcome in some underage DUI cases. However, it is not guaranteed for anyone. A dismissal generally happens when the prosecution cannot prove its case, when constitutional rights were violated, or when procedural errors undermine the evidence.
Therefore, the quality of the defense matters enormously. An attorney who carefully reviews the facts can identify weaknesses in the state’s case that might lead to a dismissal or a reduction in charges.
Common Grounds for Dismissal
There are several legal grounds that may support a motion to dismiss or suppress evidence in an underage DUI case. These include:
- Unlawful traffic stop: Police must have reasonable suspicion to pull a driver over. If the stop lacked legal justification, evidence gathered during the stop may be suppressed.
- Faulty breathalyzer or testing equipment: Breath and blood testing devices must be properly calibrated and maintained. Errors in testing can challenge the validity of BAC results.
- Improper field sobriety testing: Officers must administer standardized field sobriety tests correctly. Deviations from proper procedures can reduce the reliability of the results.
- Chain of custody issues: Blood samples must be handled and stored properly. Problems in the chain of custody can call the evidence into question.
- Violation of Miranda rights: Miranda concerns custodial interrogation, not every question to a young person. Review custody, the questions, warnings and any waiver with counsel before assessing suppression.
Moreover, in cases involving younger teenagers, the circumstances of how police interacted with the minor may raise additional legal questions. Each case is different, so it is important to consult an attorney about your specific situation.
What Happens If Charges Are Not Dismissed?
If dismissal is not supported, ask counsel about the precise charge and terms of any proposed resolution. Do not assume that a generic “wet reckless” label identifies an available Arizona disposition or that an evidence issue automatically eliminates every count.
Ask whether a specific program accepts the actual under 21 or DUI charge and whether its written eligibility criteria fit the case. First-time status alone does not establish eligibility; a general county diversion description is not proof that a DUI charge can be resolved that way.
Penalties If Convicted
Understanding what is at stake can motivate swift action. If convicted of underage DUI in Arizona, a minor may face:
- Driver’s license suspension
- Fines and court fees
- Mandatory alcohol education or treatment programs
- Probation
- Possible jail time in more serious cases
- A criminal record that can affect future employment, education, and housing
Keep federal aid questions separate from any school conduct, scholarship or enrollment requirements. Federal Student Aid states that drug convictions no longer affect federal student-aid eligibility, while incarceration can affect eligibility. Ask the school to identify the policy that actually applies rather than assume a charge automatically ends funding.
Why Early Legal Help Matters
Time is a critical factor in any DUI defense. Evidence must be reviewed, witnesses interviewed, and legal motions filed within specific deadlines. Because of this, waiting too long to seek legal help can limit the options available to you.
An experienced attorney can begin investigating the case right away. They can request police reports, review dashcam or bodycam footage, and analyze the calibration records for testing equipment. All of this takes time, so acting quickly is in your best interest.

Frequently Asked Questions About Underage DUI Dismissal in Arizona
Can a first-time underage DUI be dismissed in Arizona?
Dismissal depends on the charge, evidence and applicable law, not simply whether this is a first offense. Ask counsel what a stop, statement or testing issue would change in the prosecution’s case. Verify any proposed program’s actual eligibility terms instead of assuming diversion is available.
How long does an underage DUI stay on a record in Arizona?
In Arizona, a DUI conviction can remain on a criminal record indefinitely. However, Arizona does allow for the setting aside of convictions in some cases, which can reduce the impact on background checks. Speaking with an attorney about record relief options is worthwhile after resolving the case.
What is the zero-tolerance law in Arizona?
Arizona’s zero-tolerance law makes it illegal for anyone under 21 to drive with any detectable alcohol in their system. Unlike the standard DUI threshold, there is no minimum BAC required for a charge under this law. Even a small amount of alcohol can lead to arrest and charges.
Can parents be held responsible for an underage DUI in Arizona?
The driving allegation and an adult’s alleged provision of alcohol are separate issues. § 4-244(9) restricts furnishing alcohol to a person under legal drinking age, subject to statutory exceptions. Being a parent alone does not make someone guilty of the driver’s charge; review who allegedly provided what, when and under which provision.
Does an underage DUI affect college financial aid?
Do not assume a drug or alcohol conviction automatically disqualifies a student from federal aid. Federal Student Aid says drug convictions no longer affect federal eligibility, although incarceration can. School conduct and scholarship terms are separate; ask the institution to identify the applicable rule.
