Underage DUI in Colorado — What a UDD Charge Actually Means

Colorado treats a 0.03 BAC very differently than a 0.09 BAC for a driver under 21 — but for DACA recipients and mixed-status families, both can carry consequences that go far beyond points and fines. Here is the full picture, in one place.

When the Call Comes at 11 p.m.

Your daughter was stopped on the way home. The officer said something about a breath test, handed her paperwork, and now there is a court date and a number you do not recognize. She is seventeen. She has DACA. And the questions stacking up in your head do not have simple answers: Does this go on her immigration record? Does it affect her DACA renewal? Does it follow her onto a college application? Is it even safe for you to walk into that courthouse with her?

If you searched "underage DUI Colorado" or "UDD Colorado DACA" tonight, you have probably already found a dozen pages that explain the fine and the points and nothing else. None of them mention immigration. None of them speak to a family. That gap is exactly where the worst decisions get made — a plea that closes the case fast in traffic court and quietly reshapes a young person's future in this country.

This page fills that gap. It walks through the full picture of an underage drinking and driving (UDD) charge in Colorado: the three different charges an under-21 driver can face depending on their BAC, what happens to their license and their record, how expungement works — and, most importantly, how a UDD charge interacts with immigration status for DACA recipients, green card holders, and mixed-status families. Where a specific status needs deeper analysis, we route you to the page that handles it in full. This is the map. Read it, then talk to someone who understands both sides of the courtroom.

Colorado's Three-Charge Framework for Under-21 Drivers

Here is the single most important thing to understand, and the thing almost every competitor page gets wrong: an under-21 driver in Colorado does not face one charge. They face one of three, depending entirely on their blood alcohol concentration (BAC). The charge determines everything downstream — the penalty, the license consequence, and, for non-citizens, the immigration analysis. Knowing which tier you are in is the first strategic question in any UDD case.

For the broader DUI landscape that applies to every driver, see our DUI defense in Colorado hub. This page focuses on what changes when the driver is under 21.

UDD — Underage Drinking and Driving (BAC 0.02% to 0.05%)

This is the tier unique to under-21 drivers. Under C.R.S. § 42-4-1301(2)(d), a driver under 21 who tests at a BAC of at least 0.02% but not more than 0.05% — within two hours of driving — can be charged with UDD. The 0.02% floor is the key: it is well below the adult 0.08% limit, and it means that essentially any measurable amount of alcohol can trigger UDD liability for a young driver.

The classification matters enormously. A first-offense UDD is a class A traffic infraction — not a misdemeanor. This distinction is not a technicality; it is the hinge on which the entire immigration analysis turns, as we explain below. A second or subsequent UDD violation escalates to a class 2 traffic misdemeanor. So the same conduct that is an infraction the first time becomes a misdemeanor if it happens again — and that shift changes the immigration picture materially.

DWAI for Under-21 Drivers (BAC 0.05% to 0.079%)

Once an under-21 driver's BAC rises above 0.05%, they are no longer in UDD territory. At a BAC in the 0.05% to 0.079% range, the driver faces a DWAI (Driving While Ability Impaired) charge under C.R.S. § 42-4-1301(1)(b) — the same charge an adult would face at that BAC. DWAI is a class 2 traffic misdemeanor, not an infraction. That is a meaningful step up from UDD, both in criminal exposure and, critically, in the immigration analysis. Because DWAI is a misdemeanor and reaches the "driving under the influence" family of offenses, its immigration treatment is closer to that of an adult DUI. For the full DWAI analysis, see our first-time DUI in Colorado spoke — we do not duplicate it here.

Adult DUI When Under 21 (BAC 0.08% or Higher)

An under-21 driver who tests at 0.08% or higher faces the same adult DUI charge as any other driver under C.R.S. § 42-4-1301(1)(a) — a class 2 traffic misdemeanor for a first offense. There is no separate "youth discount" at this BAC level. This is the highest-stakes tier and the one most likely to reach the immigration consequences that make a criminal-only defense dangerous for a non-citizen. This section also marks the boundary of this page's scope: we cover UDD mechanics in depth, and we route the full adult-DUI treatment — penalties, plea strategy, immigration exposure — to the first-time DUI in Colorado spoke.

What Happens After a UDD Charge in Colorado

A UDD charge sets several processes in motion at once — the criminal or traffic case, the DMV license process, and, depending on the driver's age, either juvenile or adult adjudication. Each runs on its own clock. Understanding them is how you avoid missing a deadline that cannot be reopened.

Penalties for UDD — The Infraction Track

For a true first-offense UDD (BAC 0.02%–0.05%, no aggravating factors), the penalties reflect the class A traffic infraction structure, not the DUI/DWAI penalty regime under C.R.S. § 42-4-1307. In general terms that means: a base fine in the range of $100 as a statutory baseline; up to 24 hours of useful public service; and a mandatory alcohol evaluation, education, or treatment program completed at the driver's expense. There is generally no jail exposure at the infraction level for a first offense.

One caution the fine figure hides: the base fine is a statutory baseline, not the actual out-of-pocket cost. Colorado adds court costs, surcharges, and mandatory fees that frequently push the real total well above the base fine. And a UDD citation generally puts points on the young driver's license — reported as roughly 4 points under Colorado's points schedule — which carries its own suspension risk for a driver who accumulates too many points in a short window.

Your Driver's License — The Seven-Day Window

This is the deadline almost nobody hears about until it is too late. Colorado's Express Consent law, C.R.S. § 42-2-126, treats every driver on a Colorado road as having consented to chemical testing when lawfully arrested on probable cause — and it applies to UDD stops. When an under-21 driver tests at or above the UDD threshold (or refuses testing), the DMV process starts immediately and runs separately from the court case.

From the date on the notice of revocation, the driver has 7 days to request a DMV hearing in writing. Miss that window and the right to contest is generally forfeited — the revocation becomes final without a hearing. For a first UDD violation at a BAC not exceeding 0.05%, the revocation is generally three months, with a possible alternative track (a shorter revocation followed by a suspension period, sometimes with probationary driving privileges). Refusing the test carries its own, longer revocation — generally one year for a first refusal — and that refusal creates a separate record. See the Colorado DMV express-consent overview for the administrative side.

Colorado law requires drivers to submit to testing, and refusal carries its own consequences — including a separate revocation track and an immigration dimension worth discussing before any decision is made. This page explains the framework; it does not advise whether to refuse or submit. That is a case-specific decision only an attorney who knows your facts can help with.

Juvenile vs. Adult Adjudication — Which Track Is Your Child On?

Whether the case runs through juvenile or adult court is one of the most consequential facts for an immigrant family — and it usually turns on the driver's age. A driver under 18 who receives a UDD citation is, in many Colorado jurisdictions, handled in juvenile court rather than adult criminal court. That distinction matters far beyond the courtroom: juvenile adjudications are generally not treated as "convictions" for most purposes, including — critically — under federal immigration law. We explain that carve-out in detail in the immigration section below.

The line is real and it has hard edges. The moment a case is transferred to adult court, or the driver is already 18 or older, the juvenile framework generally no longer applies, and an adult conviction is analyzed as an adult conviction. There is also a wrinkle specific to UDD: because a first-offense UDD is a traffic infraction, some jurisdictions may process it in traffic court rather than juvenile court, and whether that changes the federal analysis is not settled.

Expungement and Record Sealing — Your Options After UDD

Colorado gives young drivers a path to clear a UDD from their record — but the rules are specific and the immigration caveat is essential. Under C.R.S. § 42-4-1715, the UDD-specific sealing statute, a person may generally petition to seal a UDD record once they are over 21, provided they were not convicted of any other offense under C.R.S. § 42-4-1301 committed while under 21, they have paid all fines and completed all court requirements, and they have never held or operated a commercial driver's license. The statute does not set a fixed waiting period in its text; instead, a court may delay consideration until enough time has passed to be confident there are no further offenses. So the honest answer to "how long do we wait?" is: once you are 21 and have met the eligibility conditions, subject to the court's discretion.

Now the caveat that matters most for non-citizen families: sealing a UDD under Colorado law does not necessarily erase it for federal immigration purposes. Federal immigration law defines "conviction" its own way, at 8 U.S.C. § 1101(a)(48)(A), and that definition can reach a state matter even after the state seals it — particularly where there was an admission of guilt and some form of punishment, penalty, or restraint, such as a fine. Whether an infraction-level UDD resolved by paying a fine meets that federal definition at all is itself an unsettled, fact-specific question. The takeaway is not that sealing is worthless — it has real value under state law — but that a family should never assume a sealed Colorado record is invisible to immigration authorities.

How a UDD Charge Affects Your Immigration Status

This is the section no competitor page has, and it is the reason families call us. A UDD charge does not affect every non-citizen the same way — the analysis depends sharply on the driver's status, their age, and which of the three charge tiers they are actually facing. What follows is a status-by-status frame, drafted carefully and hedged where the law is genuinely uncertain. For the comprehensive treatment across statuses, see our DUI and immigration consequences spoke and our DUI and immigration in Colorado analysis.

The analysis depends sharply on status, age, and which of the three charge tiers is actually in play. The items below cover the juvenile adjudication carve-out, DACA, green card holders, mixed-status families, and the single most preventable harm on this page — the plea accepted without crimmigration review.
The Juvenile Adjudication Carve-Out — What It Means for Minors

For a family whose child is under 18, this is the most important legal concept on the page. Federal regulation — specifically 8 C.F.R. § 236.22(b)(6), which governs the DACA criminal analysis — provides that, for purposes of that paragraph, juvenile delinquency adjudications are not counted as disqualifying convictions. In plain terms: where a case is genuinely resolved as a juvenile delinquency adjudication (a matter handled in juvenile court for a defendant under 18), that adjudication generally does not count as a disqualifying criminal conviction in the way an adult conviction would.

This is powerful, and it must not be overstated. Three limits define it. First, it applies to juvenile adjudications, not to adult convictions of young people — the moment a case is transferred to adult court, or the defendant is 18 or older, the carve-out generally does not apply. Second, the carve-out we are citing lives in the DACA regulation at § 236.22(b)(6); it is authority scoped to that context and should not be casually generalized to every immigration purpose. Third, as noted above, whether a traffic-infraction UDD against a minor is processed as a "juvenile delinquency adjudication" or in traffic court can affect whether the carve-out reaches it at all. This is precisely the kind of question that requires an attorney's read of the specific case.

DACA Recipients — What a UDD Actually Means for Your Status

For a DACA recipient over 18 cited for UDD, precision matters more here than anywhere else on the page — so read this carefully. The DACA criminal framework treats "driving under the influence" as a per-se significant misdemeanor. But a first-offense UDD at the infraction level (BAC 0.02%–0.05%) is not a DUI under Colorado law, and it is not a misdemeanor — it is a distinct, separate traffic infraction. Because it is neither, an infraction-level UDD does not, on its own, straightforwardly meet the "significant misdemeanor" standard in the DACA regulation, which requires a misdemeanor in the first place. In other words, we do not characterize a first-offense infraction-level UDD as a per-se significant misdemeanor — the regulation's per-se DUI category does not cleanly reach it.

That is not the same as "no immigration consequence." Whether an infraction-level UDD matters to USCIS in a renewal — as part of the broader discretionary and criminal-history analysis — is a case-specific question that requires attorney review. And the analysis shifts materially the moment the facts change: a second or subsequent UDD (a class 2 traffic misdemeanor), or a driver who actually faces DWAI or adult DUI at a higher BAC, moves into the misdemeanor-and-DUI territory where the significant-misdemeanor risk is real and much higher. For that escalated analysis, route to the first-time DUI in Colorado spoke for the DUI/DWAI mechanics and to our DACA and criminal charges spoke for the full DACA/criminal analysis.

Green Card Holders Under 21 — UDD and Good Moral Character

For a lawful permanent resident under 21, an infraction-level UDD is, on its own, unlikely to be a crime involving moral turpitude or to trigger deportability — a UDD does not carry the kind of culpable mental state that moral-turpitude analysis looks for, and a single infraction generally does not reach the deportability thresholds. But "unlikely on its own" is not "irrelevant." A UDD still enters the record, and it must be disclosed on a naturalization application. The good moral character standard under INA § 101(f) applies to the statutory period before naturalization, and how a UDD is weighed depends on the nature of the offense as adjudicated, the BAC, and the applicant's overall record. This is fact-specific analysis, not a checkbox. For the full treatment, see our how criminal charges affect your green card spoke.

Mixed-Status Families — When Your Child's Case Is Your Concern

Let us speak directly to the fear a lot of undocumented parents carry into this: that simply walking into a courthouse with your child exposes you. Here is what we can say, carefully. A minor's UDD matter is typically heard in traffic or juvenile court — not adult criminal court — and a parent's own immigration status is not put at issue by a child's UDD charge. A parent appearing as a legal guardian is not, on its own and by itself, a proceeding against the parent. What a UDD does to your child's record is a question about your child; it is not a question about you.

That said, this is 2026, and the enforcement environment is real. We will not hand you a blanket guarantee that no court-related contact ever carries any risk — that would not be honest. What we will say is this: your child's case can be handled, and it can be handled without compounding risk to your family, by attorneys who see both the criminal side and the immigration side of the room at once. That is a conversation worth having before anyone sets foot in a courthouse.

The Plea Trap — Never Accept Without Crimmigration Review

Here is the most preventable harm on this page. A plea that looks like a fast, clean resolution in traffic court can quietly reshape a young person's immigration future. For a minor, accepting certain admissions — even in juvenile court — can still touch the immigration record depending on how the matter is charged and resolved. For a driver who is 18 or older, the difference between pleading to a UDD (infraction) and pleading to a DWAI or DUI (misdemeanor) can be the difference between preserving DACA eligibility and jeopardizing it. The label on the plea is not a detail. It is the whole case.

The right plea on a UDD charge is not the one that closes the file fastest. It is the one that protects your child's future in this country. A criminal-only attorney who does not practice immigration law can give advice that is perfectly sound in traffic court and quietly wrong for immigration — because the most consequential question in the case is one they were never trained to ask. The correct move, every time, is to have a crimmigration attorney evaluate the plea offer before it is accepted — not at the next court date when it is already on the record.

What Parents Need to Know — Protecting Your Child and Your Family

If you are the parent reading this, you are very likely the one who has to act — and act quickly. This section is for you.

Acting Fast — The 7-Day DMV Hearing Window

The most urgent clock is the DMV's. Your child has 7 days from the date on the notice of revocation to request a hearing in writing, and missing that window generally means an automatic license revocation with no chance to contest it. That is not a lot of time when you are also absorbing the shock of the call. If your child has been cited for UDD, the license question deserves attention right away — not after the first court date. An attorney can request the hearing and preserve the option to fight the revocation while the rest of the case is still being evaluated.

Bilingual Representation From the First Call

Novo Legal Group is a Spanish-first immigration practice — every attorney and every staff member is bilingual in English and Spanish. For many of the families we serve, the most important legal conversation of their lives should not have to happen in a second language. When you call, the intake, the consultation, and the immigration analysis can all happen in the language where you are most precise. That is not an add-on service. It is who we are.

When the Criminal Defense Team and Immigration Team Work Together

Most firms would hand you a criminal defense attorney and tell you to go find your own immigration attorney. That handoff is exactly where UDD cases involving non-citizen young people go wrong — because the plea decision has to account for both sides of the room, in real time, before anything is on the record. At Novo Legal, the criminal defense side and the immigration side work the same file from day one. We appear in Colorado's traffic and criminal courts and before USCIS and the immigration courts, and the two analyses happen in conversation, not in sequence. The recommendation we bring you accounts for both courtrooms. Every time.

Fight for Your Child's Future — Schedule a Consultation

A UDD charge does not have to define a young person's future — but the right defense, from the first call, makes all the difference. The DMV clock is running. A court date is coming. And a plea offer may arrive before your family has understood what it really means. This is the exact situation we fight for: a young person with everything ahead of them, and a family that deserves attorneys who understand both what happens in traffic court and what happens to an immigration case.

Call us at (888) 746-5245 or schedule a consultation. We handle consultations by phone, video, and in person at our Denver office, and every member of our team is bilingual.

A UDD charge is not the end of your child's story.

Frequently Asked Questions — Underage DUI (UDD) in Colorado

What is a UDD charge in Colorado?

UDD stands for Underage Drinking and Driving. Under C.R.S. § 42-4-1301(2)(d), a driver under 21 who tests at a BAC of at least 0.02% but not more than 0.05% can be charged with UDD. A first-offense UDD is a class A traffic infraction — not a misdemeanor — and generally carries a base fine, useful public service, a mandatory alcohol education or treatment program, and points against the driver's license. A second or subsequent UDD escalates to a class 2 traffic misdemeanor.

Is a UDD the same as an adult DUI in Colorado?

No. Colorado uses a three-tier framework for under-21 drivers. A BAC of 0.02%–0.05% is a UDD (a traffic infraction on a first offense). A BAC of 0.05%–0.079% is a DWAI (a misdemeanor). A BAC of 0.08% or higher is a standard adult DUI (a misdemeanor). The charge — and its consequences — depends on the BAC.

Does a UDD affect DACA?

It depends on the facts, and this is a question to bring to an attorney. A first-offense UDD at the infraction level is not a DUI under Colorado law and is not a misdemeanor, so it does not, on its own, straightforwardly meet the "significant misdemeanor" standard used in the DACA criminal analysis. But a second-offense UDD (a misdemeanor), a DWAI, or an adult DUI moves into higher-risk territory. Whether any UDD affects a specific DACA case requires case-specific attorney review. See our DACA and criminal charges page.

My child is under 18 — does a juvenile UDD count for immigration?

Federal regulation at 8 C.F.R. § 236.22(b)(6) provides that, for the DACA criminal analysis, juvenile delinquency adjudications are not counted as disqualifying convictions. So a matter genuinely resolved as a juvenile adjudication generally does not count the way an adult conviction would. Important limits: this applies to juvenile adjudications, not to adult convictions of young people; it is authority scoped to the DACA context; and whether a traffic-infraction UDD is processed as a juvenile adjudication can affect the analysis. Have an attorney review the specific case.

Can a UDD be sealed or expunged in Colorado?

Yes, under C.R.S. § 42-4-1715, generally once the person is over 21, has no other C.R.S. § 42-4-1301 conviction from when they were under 21, has paid all fines and completed all requirements, and has never held a commercial driver's license. The statute does not set a fixed waiting period. But note: sealing a UDD under Colorado law does not necessarily erase it for federal immigration purposes, which uses its own definition of "conviction." A family should never assume a sealed Colorado record is invisible to immigration authorities.

Is it safe for me to go to court with my child if I am undocumented?

A minor's UDD case is typically heard in traffic or juvenile court, and a parent's own immigration status is not put at issue by a child's UDD charge — a parent appearing as a legal guardian is not, by itself, a proceeding against the parent. We will not promise that no court-related contact ever carries any risk in the current environment, but your child's case can be handled without compounding risk to your family. This is exactly the kind of conversation to have with a crimmigration attorney before anyone goes to court.
