Board Certified DUI Defense
Utah Juvenile and Under-21 DUI Defense Attorney
Since 1998Board CertifiedNCDD Faculty
Juvenile and under-21 DUI defense is a different assignment than adult DUI work, and the reason is arithmetic. Utah holds a driver under 21 to any measurable amount of alcohol, so these cases turn on readings far below the range breath instruments were built to measure reliably. A single traffic stop can also open up to three separate proceedings at once, and identifying which one a young person is actually facing is the first real step in the defense.
Glen Neeley has defended DUI cases across Utah since 1998. He is board certified in DUI defense, serves on the NCDD faculty teaching other lawyers the science behind breath and blood testing, and completed the Borkenstein Course on alcohol and highway safety. This page explains the three charges a stop can produce, the license numbers as the statutes actually write them, why the science matters more at ultra-low readings, and why the age of the driver at arrest changes the record timeline more than any other single fact.
Three Charges Can Come From One Stop
Parents are usually told their child got a DUI. Often that is not precisely what happened. A stop involving an underage driver can generate one charge, two, or all three of the following, and each one asks the state to prove something different.
| Charge | Statute | What it is | Maximum or result |
|---|---|---|---|
| Not-A-Drop | Section 53-3-231 | Administrative license action, not a criminal charge, applying at any measurable alcohol concentration shown by a chemical test | Six-month license suspension on a first offense |
| Minor in possession | Section 32B-4-409 | Criminal charge; under Subsection (1)(f) it reaches any measurable alcohol in the body, with no physical possession required | Class B misdemeanor, up to 180 days and a fine up to $1,000 |
| DUI | Section 41-6a-502 | Criminal charge requiring .05 or higher, or impairment that renders the driver incapable of safely operating a vehicle | A reading of .01 or .02 does not by itself establish this charge |
The distinction is not academic. The administrative Not-A-Drop action is handled by the Driver License Division and never requires proof of impairment. The minor in possession charge under Section 32B-4-409 is criminal but, under Subsection (1)(f), needs only a measurable amount in the body. A criminal DUI under Section 41-6a-502 is the one that carries the full penalty structure, and it requires .05 or higher, or impairment that renders the driver incapable of safely operating a vehicle. Our companion page on zero-tolerance BAC rules for drivers under 21 walks through how the administrative and criminal tracks run from the same chemical sample.
Why Under-21 Cases Turn on the Testing Science
At the zero-tolerance threshold, an underage driver faces exposure at concentrations well below the range breath instruments were designed to measure reliably. That single fact reorders the whole defense.
Every breath instrument carries an inherent margin of error. At .08 or .10, a margin of plus or minus .005 rarely changes the result. At .02, that same margin can equal or exceed the entire reading, which turns an unreliable number into the central issue. Mouth alcohol from recent eating, reflux (GERD), or residual mouthwash can produce a false positive that would be immaterial at an adult threshold and decisive here. Calibration drift that nobody would notice at .08 becomes the case at .02.
Glen completed the Borkenstein Course on alcohol and highway safety, the same program forensic toxicologists attend, and holds SFST certification through a program developed by NHTSA-certified instructors. That background is what lets a low reading be challenged on the science rather than argued around. In every under-21 case we request the calibration logs, maintenance records, and operator certification history for each device used, and we examine how the breath and chemical testing was actually conducted, including the observation period and the possibility of alcohol from a non-beverage source.
The License Consequences, With Actual Numbers
The license side of an underage case runs on its own track, separate from the courtroom. For a driver age 20 or under at arrest on a first offense, the Driver License Division applies the following.
| Action (driver 20 or under, first offense) | Governing section | License result |
|---|---|---|
| Not-A-Drop arrest | Section 53-3-231 | Six months |
| Per Se arrest | Section 53-3-223 | Six months, not the 120 days that applies to adults |
| Refusal to submit to a chemical test | Implied consent | Revocation until age 21 or two years, whichever is longer |
| Conviction under 32B-4-409 | Section 53-3-219 | One year on a first order, two years on a second |
The refusal figure deserves emphasis. It is the harshest license outcome available to a young driver, and the decision to refuse the chemical test is made at the roadside, before any lawyer is involved. For a 16- or 17-year-old, refusing can mean no driving privileges until age 21.
Where a DUI conviction or juvenile adjudication follows, Section 41-6a-509 sets the periods by age bracket rather than the adult 120 days. For a driver 19 or 20 at arrest, that is suspension until age 21 or one year, whichever is longer, with revocation until 21 or two years where a qualifying prior falls within ten years. Section 41-6a-509 credits days already served administratively from the same occurrence, so the two actions do not simply stack. A separate conviction under Section 32B-4-409 carries its own suspension under Section 53-3-219, one year on a first order and two years on a second, which is why the charge a family treats as minor can carry the longer license consequence. The full breakdown of underage driving-privilege periods lays each of these out by age.
Two further restrictions attach on a DUI conviction. Under Section 41-6a-518.2, a conviction where the driver was under 21 carries a two-year ignition interlock restriction, longer than the 18 months that applies to a standard adult first offense. And under Section 41-6a-530, every person under 21 is an alcohol-restricted driver until age 21, meaning no measurable alcohol at all while operating a vehicle.
Which Court Hears the Case, and What That Changes
The age of the driver at arrest decides the forum, and the forum shapes almost everything that follows.
For a driver under 18, the case proceeds in juvenile court, which holds exclusive jurisdiction over DUI-related traffic offenses by minors, along with automobile homicide, reckless driving, joyriding, and fleeing an officer. That forum is not something a lawyer can select or argue for: it is where the case belongs. What the juvenile system does offer is different terminology (adjudication rather than conviction, disposition rather than sentence), broader dispositional options, confidentiality protections, and a materially faster path to clearing the record. Its cleanest resolution is a nonjudicial adjustment, which resolves a referral without formal court proceedings.
For a driver who is 18, 19, or 20, the case proceeds in adult criminal court while the under-21 rules still govern the license side. That hybrid creates its own strategy and much higher record stakes. In adult court, a plea in abeyance or a reduction to impaired driving under Section 41-6a-502.5 avoids the license and interlock consequences that are keyed to a Section 41-6a-502 conviction. We work out which of these outcomes is realistically available and negotiate toward it.
The Record Timeline: Age at Arrest Changes Everything
This is the single most important practical point for families, and the strongest reason to take the case seriously from the first day. How the case resolves determines when, and whether, the record can be cleared.
| Case resolved as | Earliest path to clearing the record |
|---|---|
| Juvenile adjudication (driver under 18 at arrest) | Petition under Title 80, once the person is 18 and at least one year has passed since juvenile court jurisdiction ended, subject to the statutory criteria |
| Adult DUI conviction (driver 18 to 20 at arrest) | The full ten-year DUI expungement wait, measured from completion of the entire sentence |
The gap between roughly one year and ten years is why the difference between a DUI conviction and a reduction to impaired driving matters so much for a college-age client. For a young person adjudicated at 16 whose disposition completes at 17, expungement eligibility can arrive in the late teens. An adult DUI conviction instead carries the full ten-year wait, and a felony DUI is ineligible unless it is first reduced to a misdemeanor. Because clearing a juvenile record works differently from clearing an adult one, how a juvenile DUI record is sealed or expunged is worth understanding before the case resolves, not years later.
How a Conviction Follows a Young Person
A juvenile record is not automatically sealed in Utah. Without affirmative legal action, it stays accessible and can surface in background checks long after the case closes. The reach of that record is why non-conviction outcomes are worth fighting for.
- College admissions: most applications ask about criminal history, and a conviction becomes a required disclosure that committees weigh alongside grades.
- Scholarships and institutional aid: many programs carry conduct conditions a conviction can violate. On federal aid, one widely repeated claim is now out of date, because the FAFSA Simplification Act removed the drug-conviction disqualification for Title IV aid and the question came off the FAFSA beginning with the 2023-24 award year. Private scholarships still apply their own standards.
- Insurance: young drivers already pay elevated premiums, and a conviction compounds the cost for years.
- Employment and internships: background checks for internships, licensing programs, and early-career jobs routinely surface these records, with healthcare, education, and finance applying stricter scrutiny.
- School and athletic eligibility: high school and college conduct codes often move faster than the court case, producing activity suspensions before the legal matter resolves.
How the Case Moves, and When to Call
Two proceedings begin at the same time. The criminal or delinquency case addresses the charge, and the Driver License Division action addresses the license. The catch is the deadline: the hearing to contest the license action must be requested within 10 calendar days of the arrest. Weekends and holidays count. Miss it, and the suspension takes effect with no chance to contest it, no matter how the court case ends.
We handle both tracks from the first consultation, reviewing the arrest report, the test results and the method used, the field sobriety documentation, and any body camera or dashcam footage. We assess whether the stop was lawful, whether testing followed protocol, and whether the result is reliable enough to sustain the charge. Where the evidence is vulnerable we challenge it; where a nonjudicial adjustment or a reduction is available we negotiate for it; and throughout, we coordinate with the family around college applications, scholarship deadlines, and enrollment decisions.
Parents should call immediately, before the 10-day deadline passes, because requesting the hearing is what preserves the right to challenge the suspension.
Questions Parents Ask
My child barely had anything to drink. Can they still be charged?
Yes, and what they are charged with depends on the reading. Any measurable amount supports the administrative Not-A-Drop action and can support a class B misdemeanor under Section 32B-4-409. A criminal DUI under Section 41-6a-502 requires .05 or higher, or actual impairment. Whether a low reading is even reliable is a separate question, because at ultra-low levels mouth alcohol, calibration issues, and observation-period problems can all produce a number that does not reflect true blood alcohol concentration.
How long will my child lose their license?
Six months for a first Not-A-Drop or Per Se arrest. A refusal is a revocation until age 21 or two years, whichever is longer. A DUI conviction adds periods under Section 41-6a-509 by age bracket, and a separate conviction under Section 32B-4-409 carries its own one-year suspension under Section 53-3-219.
Does refusing the test help?
No. For a driver under 21 it produces the longest license loss available, and the decision is made at the roadside before any attorney is involved.
Will this show up on college applications?
If the case ends in a conviction, most applications require disclosure, which is a central reason we prioritize non-conviction outcomes. Federal financial aid is no longer affected by a drug-related conviction, but private scholarships and institutional programs may still apply conduct conditions.
Can a juvenile record be expunged in Utah?
Yes, by petition under Title 80, once the person is 18 and one year has passed since juvenile court jurisdiction ended, subject to the other statutory criteria. It is not automatic, and it is separate from the driving record kept by the Driver License Division. Because an adult DUI conviction instead carries a ten-year wait, the age at arrest changes the timeline dramatically.
Do we need a DUI specialist?
Any licensed attorney can take the case. The real question is whether they can challenge testing evidence at ultra-low readings, know juvenile court procedure and nonjudicial adjustment, recognize which of the three possible charges is actually in play, and coordinate strategy with school timelines. A general practitioner may not see the technical weakness in a .02 reading that a DUI specialist spots immediately.
Can parents be held responsible?
Parents are generally not criminally liable for a minor's offense. A parent who knowingly provides alcohol to a minor can face separate charges, however, and we clarify each family member's exposure during the consultation.
