Felony DUI in Colorado — When a 4th Offense Becomes a Class 4 Felony

A fourth DUI in Colorado is not another misdemeanor. It is a felony charge with prison time, a permanent record, and immigration consequences that can end your life in this country. Here is what you are actually facing and what can be done about it.

You Just Found Out Your DUI Is a Felony

The DA said the word. Your public defender said it. Now it is on the charging document: felony. You had DUIs before — years ago, in other states, charges you resolved and moved on from. You did not understand why this one was different. You are trying to figure it out on your phone during a work break, and the fear is running on two tracks at once: prison, and everything that follows if you are not a U.S. citizen.

This is not like the DUIs before. Colorado's felony DUI law has no washout period, no forgiveness for distance or time. It counts everything — priors from other states, DWAI convictions, charges from twenty years ago — and when the total hits three prior qualifying convictions, the new charge is a class 4 felony under Colorado law. That is a fundamentally different legal situation than a misdemeanor: different court, different judge, different sentencing range, different immigration exposure.

This page explains what makes a Colorado DUI a felony, what a felony conviction actually costs, how the criminal court process works at the felony level, and — most importantly, for the non-citizens reading this — why a felony DUI is categorically more dangerous to your immigration status than any misdemeanor you have survived before. For the full immigration analysis by status, we route to the dedicated spoke pages. This page gives you the complete picture before you walk into any courtroom or sign any plea.

Why Your 4th DUI Is a Felony — How Colorado's Prior-Offense Threshold Works

Most people arrested for a DUI in Colorado are facing a misdemeanor. A person with three prior qualifying convictions is not. Understanding exactly how Colorado counts prior offenses — and what counts as a prior — is the first question in any 4th-offense defense, because people are frequently blindsided by the felony charge when they assumed their history would not follow them.

The Felony Trigger — Three Prior Convictions Under C.R.S. § 42-4-1301

Under C.R.S. § 42-4-1301(1)(a), a DUI or DWAI conviction with three or more prior convictions — arising from separate and distinct criminal episodes — for DUI, DUI per se, or DWAI is a class 4 felony. The statute also expressly includes prior vehicular homicide (§ 18-3-106(1)(b)) and vehicular assault (§ 18-3-205(1)(b)) convictions in the qualifying-prior list.

Two elements of this rule catch people off guard. First, there is no time limit on prior convictions. Colorado's felony DUI statute has no ten-year lookback, no washout period, no forgiveness for age or rehabilitation. A DUI from 2001 counts the same as a DUI from last year. The statute counts all prior qualifying convictions in the person's lifetime, and all of them count. Second, each prior conviction must arise from a separate and distinct criminal episode — multiple DUIs arising from a single incident would not each count as a separate prior. But separate incidents, no matter how far apart in time, each count individually.

What Counts as a Prior — Including Out-of-State Convictions

This is the provision that blindsides the most people. Colorado does not limit prior-conviction counting to Colorado offenses.

C.R.S. § 42-4-1301(1)(j) states that a person is deemed to have a prior conviction "if the person has been convicted under the laws of this state or under the laws of any other state, the United States, or any territory subject to the jurisdiction of the United States, of an act that, if committed within this state, would constitute any of these offenses."

In plain language: a DUI or DUI-equivalent conviction from New Mexico, Texas, California, or any other state counts as a prior if the conduct would have qualified as a DUI, DWAI, vehicular assault, or vehicular homicide under Colorado law. The statute applies a functional equivalency standard — it asks what the out-of-state conduct was, not what the out-of-state statute called it.

Whether a specific out-of-state conviction qualifies under this standard is a legal determination that requires attorney review of the specific statute of conviction in the other state. Some out-of-state offenses will be clear equivalents; others may not be. That determination matters — a prior that does not qualify drops the count below the felony threshold. A skilled defense attorney challenges out-of-state priors at arraignment, not after a plea is entered.

DWAI Priors Count Too — The Lifetime Lookback Explained

DWAI — Driving While Ability Impaired — is a lesser Colorado charge than DUI, available at BAC levels of 0.05%–0.079% or when driving ability is impaired to the slightest degree. Many people who have DWAI convictions believe those convictions were a lesser matter — a reduction, a compromise — that carries less weight in future proceedings.

Under C.R.S. § 42-4-1301(1)(a), DWAI convictions are expressly included in the prior-conviction count for the felony DUI threshold. A person with two DWAI convictions and one DUI conviction who is now charged with a new DUI has three qualifying priors. The new charge is a felony. The label of the prior offense — DWAI versus DUI — makes no difference for counting purposes.

This also means a person who negotiated a plea from DUI to DWAI in a prior case, thinking they were reducing their exposure, may have created a prior that still counts toward the felony threshold years later. People facing a 4th DUI charge whose history includes any combination of DUI, DWAI, DUI per se, vehicular assault, or vehicular homicide convictions should have an attorney review the full prior-conviction picture before any count is assumed. For the first-offense mechanics and the DUI/DWAI distinction in detail, see our first-offense DUI in Colorado spoke.

What a Felony DUI Conviction Costs You in Colorado

A class 4 felony DUI is not a misdemeanor with a larger fine. It is a fundamentally different category of conviction, with sentencing handled in district court rather than county court, a range that includes years in the Colorado Department of Corrections, and immigration consequences that make the criminal consequences look manageable by comparison. Here is what the criminal side of the ledger looks like.

Criminal Penalties — Class 4 Felony Ranges

Under C.R.S. § 18-1.3-401, a class 4 felony conviction in Colorado carries:

  • Prison term: 2 to 6 years in the Colorado Department of Corrections
  • Fine: $2,000 to $500,000
  • Mandatory parole: 3 years following any DOC prison sentence

These are the statutory ranges for a class 4 felony; actual sentences depend on judicial discretion, the specific BAC level, the facts of the arrest, the defendant's full criminal history, any aggravating circumstances (injuries, child passengers, extreme BAC), and local court practice in the jurisdiction where the case is pending. No attorney can promise a specific sentence, and no reader should assume they will land at any particular point in the range.

The 3-year mandatory parole following any DOC sentence is a significant and often overlooked consequence. A client who serves a DOC sentence is under correctional supervision for 3 additional years after release — a period during which immigration enforcement can intersect with the supervision conditions.

Probation and Community Corrections — The Alternatives to Prison

A class 4 felony DUI sentence does not have to mean DOC prison. Colorado law permits sentencing to probation or community corrections (a residential halfway-house sentence) in appropriate cases. For defendants who receive a probation sentence, C.R.S. § 42-4-1307(6.5) imposes a mandatory minimum jail term as a condition of that probation: at least 90 days but not more than 180 days of imprisonment as a probation condition, or at least 120 days to 2 years if served through a work-release program, plus at least 48 hours of useful public service.

The distinction between probation and DOC prison matters — especially for non-citizens. Probation and community corrections generally keep a client outside federal immigration custody while serving the sentence. A DOC prison sentence may not. But the critical framing for non-citizens is this: it is the conviction that triggers immigration consequences, not only the custody. A probation sentence does not eliminate immigration risk — it affects where you serve time, not what the conviction means.

Driver's License — Revocation, Interlock, and Reinstatement

A felony DUI conviction triggers longer administrative license revocation periods than a misdemeanor DUI, plus mandatory ignition interlock requirements as a condition of any restricted driving privileges during and after the revocation period. The administrative DMV process runs in parallel with the criminal court case and has its own deadlines — including a 7-day window to request a hearing from the date of the notice of revocation.

The Express Consent law mechanics — the 7-day deadline, the hearing process, the refusal consequences — are covered in full on our first-offense DUI in Colorado spoke. The felony DUI adds length and seriousness to every phase of that process; the underlying mechanics are the same.

For non-citizens, administrative license revocation has an additional dimension: some visa categories require a valid driver's license, and the administrative process affects that independently of the criminal case outcome.

Vehicular Assault and Vehicular Homicide — Adjacent Charges That Change Everything

If the DUI arrest involved an accident with serious injury to another person, the DA may file vehicular assault charges under C.R.S. § 18-3-205(1)(b)(I) — a class 4 felony — separately from or in addition to the DUI charge. If the accident involved a death, vehicular homicide while DUI under C.R.S. § 18-3-106(1)(b)(I) is a class 3 felony, carrying a sentencing range of 4 to 12 years DOC under § 18-1.3-401 — a substantially more serious exposure than the class 4 felony DUI.

These are not variations of a DUI charge. They are distinct criminal offenses with their own elements, their own sentencing frameworks, and their own immigration consequences. If your case involves an accident with injuries or a death, the defense analysis is entirely different from a standard felony DUI. Contact an attorney immediately — the complexity compounds at every stage. This page does not provide defense strategy for vehicular assault or vehicular homicide charges; those cases require immediate specialized counsel.

The Colorado Felony DUI Court Process — What Is Different From a Misdemeanor

A misdemeanor DUI is handled in county court. A felony DUI is handled in district court. That distinction matters at every stage — the timeline is longer, the stakes are higher, the procedural steps are more complex, and the decisions made at each stage have larger consequences. Understanding where you are in the process and what each stage means is the difference between walking in blind and walking in prepared.

Felony Arraignment and Bond — Why the Stakes Are Higher

When the DA files a class 4 felony DUI, the case originates in district court. At arraignment, you are formally advised of the charges and enter a plea — almost always "not guilty" at this stage. Bond is set based on the nature of the charge, the defendant's criminal history, and flight risk — felony bond amounts are typically higher than misdemeanor bond amounts, and a prior DUI history is not an argument in your favor at the bond hearing.

If you are not a U.S. citizen, the bond hearing carries an additional layer of urgency. ICE detainers can attach while you are in custody. Having crimmigration counsel present at or before arraignment — not retained after a plea is already on the record — is the single most important timing decision in the case.

Preliminary Hearing and Discovery — Where Cases Are Built or Broken

The preliminary hearing is a stage in a felony DUI case that does not exist in a misdemeanor — it is one of the reasons the felony process takes longer and creates more strategic opportunity. At a preliminary hearing, the prosecution must establish probable cause for each charge. The defense can challenge whether the evidence supports the charge as filed, and can cross-examine witnesses under oath, locking in testimony that can be used at trial.

Discovery in a felony DUI case is more extensive than in a misdemeanor: body camera footage, dashcam footage, field sobriety test records, breathalyzer or blood test chain of custody, officer training and certification records, and any prior-conviction documentation the prosecution intends to use to establish the felony threshold. Every piece of that discovery is a potential challenge. The prior-conviction records — including out-of-state records — may not have been properly authenticated. The chemical test may have procedural vulnerabilities. The traffic stop may have Fourth Amendment problems.

This is where a skilled felony DUI defense attorney earns the outcome. A preliminary hearing is not a formality. It is the moment to apply real pressure.

Plea Negotiation — Can a Felony DUI Be Reduced?

In some cases, a class 4 felony DUI can be negotiated to a lesser charge — potentially a class 1 misdemeanor or a DWAI. Whether that is possible depends on the facts, the jurisdiction, the strength of the evidence, and the specific prior-conviction record.

For non-citizens, the plea negotiation stage is where crimmigration analysis is most critical. A plea to a "lesser" charge may reduce criminal exposure — and may or may not be safer for immigration purposes. The immigration consequences of each possible plea must be evaluated individually before any offer is accepted. A plea that looks like a win in criminal court can be catastrophic for immigration status. See the immigration section below, and do not accept any plea — in a felony DUI or anywhere else — before a crimmigration attorney has reviewed the specific offer and its immigration consequences.

Trial — The Full Defense

Not every felony DUI should resolve through a plea. When the evidence is challengeable — the stop, the chemical test, the prior-conviction authentication, the probable-cause basis for the charge — going to trial may be the right defense. A felony DUI is a jury-triable case. An acquittal is the cleanest possible immigration result: a charge that never results in a conviction never reaches federal immigration analysis.

Our attorneys evaluate every felony DUI case on its evidence before recommending a path. Because for non-citizens, "better than a conviction" is sometimes the only option that protects everything they have built in this country.

How a Felony DUI Threatens Your Immigration Status

If you are not a U.S. citizen, this is the section that determines whether you keep your life in this country. A felony DUI is not a misdemeanor with a bigger fine. It is a categorically different immigration problem. The analysis below explains why — by status — and what is actually at stake.

For the full immigration analysis by status, see our DUI and immigration consequences spoke and our criminal defense for immigrants hub. This page gives the felony-specific picture.

The Felony Line — Why Criminal Felony Is Not Automatically an Immigration "Aggravated Felony"

This is the most load-bearing legal question on this page, and it must be stated precisely.

A class 4 felony DUI in Colorado is NOT automatically an "aggravated felony" under immigration law — even though Colorado classifies it as a felony. The immigration classification "aggravated felony" is defined by the Immigration and Nationality Act at 8 U.S.C. § 1101(a)(43), and that definition has its own categories that do not map onto Colorado's felony classification.

The most commonly raised pathway for classifying a DUI as an aggravated felony is the "crime of violence" category under 8 U.S.C. § 1101(a)(43)(F), which requires both (1) a crime of violence as defined in 18 U.S.C. § 16, and (2) a term of imprisonment of at least one year actually imposed. Under the Supreme Court's doctrine, the standard DUI — including a felony DUI — under current federal law generally lacks a viable pathway to aggravated-felony status through this route. The Court has held that driving under the influence, which involves negligence or recklessness rather than intentional force, does not meet the crime-of-violence definition under 18 U.S.C. § 16(a). The Court has also struck down 18 U.S.C. § 16(b) — the broader residual clause — as unconstitutionally vague. A separate line of Supreme Court decisions has further reinforced that offenses committed with a reckless (rather than intentional) mens rea face significant headwinds under the elements clause of the crime-of-violence definition.

Under current law, no published decision has established that a standard Colorado class 4 felony DUI constitutes an aggravated felony through the crime-of-violence pathway. But that framing has two important limits. First, the aggravated-felony analysis depends entirely on the specific facts of the case — the charges as filed, the sentence actually imposed, and current federal caselaw at the time of any immigration proceeding. A sentence of one year or more, or additional charges that carry different immigration classifications (vehicular homicide, for instance), change the analysis. Second, immigration law is not static: circuit-court decisions and BIA rulings can shift the doctrine, and the current state of the law should be confirmed with an attorney before any plea is entered.

The practical framing for non-citizens: the aggravated-felony question is real, it is fact-specific, it is one of the most consequential questions in crimmigration law, and it is not answered by the criminal court. It is answered by an attorney who understands both systems — before any plea is entered.

Is a Felony DUI a Crime Involving Moral Turpitude?

A crime involving moral turpitude (CIMT) — conduct that is inherently base, vile, or depraved — is one of the most consequential immigration classifications because it can trigger both deportability under INA § 237(a)(2)(A) and inadmissibility under INA § 212(a)(2)(A).

For a standard alcohol DUI, the BIA has generally not found the offense to constitute a CIMT under the categorical approach — the same framework described in our first-offense DUI in Colorado analysis. The categorical approach asks whether the minimum conduct criminalized by the state statute necessarily involves moral turpitude; an alcohol-impairment standard under Colorado's DUI statute does not, on its own, require the kind of mens rea that courts have historically associated with moral turpitude.

At the felony level, however, the aggravating circumstances of a 4th-offense charge may carry more weight in a CIMT analysis. Repeat convictions, elevated BAC levels, and the deliberate choice to drive despite a significant prior history are exactly the facts courts examine when assessing whether conduct rises to moral turpitude. The analysis remains fact-specific and statute-specific — no reader should assume that prior CIMT analysis of misdemeanor DUI governs a felony DUI charge without attorney review of the specific facts and the current state of the law.

The CIMT analysis for a felony DUI is, at a minimum, more complex and more uncertain than for a first-offense misdemeanor. That uncertainty is the argument for fighting the charge — not for assuming any specific outcome.

Green Card Holders — The Permanent Bar Risk

For lawful permanent residents, a standard misdemeanor DUI without aggravating factors generally does not, on its own, trigger the deportability grounds under the INA. A felony DUI is a different story, and that difference needs to be stated clearly.

A felony DUI conviction substantially elevates the immigration risk for green-card holders on two fronts. First, the aggravated-felony question — analyzed above — becomes a live question rather than a remote possibility. A sentence of one year or more, which falls within the class 4 felony range, could in principle trigger an aggravated-felony analysis that does not arise in a misdemeanor context. Second, the CIMT analysis at the felony level — with the repeat-conviction aggravating factors described above — creates more uncertainty than a first-offense misdemeanor.

Beyond deportability, a felony DUI conviction creates a credible barrier to naturalization. The good moral character requirement for naturalization under INA § 101(f) looks at the person's conduct during the statutory period. A felony conviction during that period reflects adversely on the good moral character analysis and may create a bar or a materially more difficult path to naturalization. The specific duration and nature of that impact depends on the facts and is subject to attorney analysis — this page does not state a specific naturalization bar period.

A green card is not a shield against a felony DUI conviction. Fighting the charge — not managing the sentence — is the only strategy that fully protects immigration status. For the full analysis of how criminal charges interact with LPR status, naturalization, and the deferred-judgment question, see our how criminal charges affect your green card page and our DUI and immigration in Colorado analysis.

DACA Recipients — A Felony DUI Likely Ends DACA Eligibility

For DACA recipients, this section must be read as a separate analysis from the first-offense DUI page. A first-offense DUI raises the significant-misdemeanor question under DACA policy — a separate prong that the first-offense spoke addresses in detail. A felony DUI raises a categorically different bar.

Under 8 C.F.R. § 236.22, any felony conviction is an absolute bar to DACA. There is no discretion, no exception, no sentence threshold. A person convicted of a class 4 felony DUI is categorically ineligible for DACA — period. This is not a difficult judgment call requiring analysis of the specific conviction's immigration character. It is a categorical rule that applies regardless of BAC, regardless of sentence, regardless of the specific facts of the arrest.

This bar is separate from and in addition to the significant-misdemeanor DUI analysis that governs first-offense and misdemeanor cases. Both bars exist; they operate independently. A DACA recipient who pleads to a felony DUI has hit the absolute bar — the significant-misdemeanor analysis is no longer the relevant question.

For the full DACA analysis — including the program's current legal posture under ongoing federal court litigation — see our DACA and criminal charges spoke.

Visa Holders — Entry, Renewal, and Inadmissibility Risk

For nonimmigrant visa holders — F-1 students, H-1B workers, L-1 transferees, and others — a felony conviction on the criminal record creates substantial inadmissibility risk at any future port of entry or consulate interview. The inadmissibility analysis that applies at a visa renewal or re-entry encounter is separate from the deportability analysis that applies in removal proceedings, and the felony classification of the conviction is a significant factor in that analysis.

The specific immigration consequence for a visa holder depends on the visa category, the nature of the conviction, and the consular officer or USCIS adjudicator's discretionary analysis. What can be said generally: a felony DUI creates more inadmissibility risk than a misdemeanor DUI, and the risk compounds at every future point of contact with immigration adjudicators.

For the full visa-holder analysis by category, see our DUI and immigration consequences spoke.

Undocumented Individuals — Compounded and Immediate Exposure

For undocumented individuals, a felony DUI creates exposure that is both immediate and long-term — and both tracks are more severe than in a misdemeanor context.

At arrest, the criminal booking process puts a person into law enforcement databases that ICE monitors. The felony charge raises the profile of the enforcement encounter significantly compared to a misdemeanor. Upon conviction, the felony record creates the criminal grounds that removal proceedings can be built on — and the aggravated-felony and CIMT questions analyzed above become live deportation grounds, depending on how the conviction is characterized. The intersection with INA § 236(c) mandatory detention — which applies to certain categories of criminal aliens — is an indirect but serious risk exposure that depends on the underlying immigration grounds charged and the specific sentence imposed.

From the moment of arrest in a felony DUI case involving an undocumented person, having both criminal and immigration defense counsel working together is not optional. The criminal case and the immigration case are running simultaneously from the courthouse door. If you are undocumented and facing a felony DUI charge, do not wait for the criminal case to resolve before consulting an immigration attorney.

The Plea Trap at Felony Level — The Stakes Are Existential

This is the section where we speak directly. A plea to a felony DUI — even one negotiated down from a higher charge, even one that results in probation rather than prison — can trigger immigration consequences that will end a person's life in this country. And those consequences will not be visible to a criminal defense attorney who does not practice immigration law.

Here is what a crimmigration attorney analyzes that a criminal-only attorney does not:

The conviction itself. Under the INA's definition of "conviction" at 8 U.S.C. § 1101(a)(48)(A), any plea of guilty or nolo contendere combined with some form of punishment, penalty, or restraint on liberty — including probation — is a conviction for immigration purposes. A deferred judgment in Colorado requires entering a guilty plea first. That plea, combined with any court-imposed condition, is generally treated as a conviction under federal immigration law regardless of what later happens on the state record. A person who accepts a deferred judgment on a felony DUI believing their record will be clean discovers at a naturalization interview, or at a port of entry, or in removal proceedings, that federal immigration law counted the plea as a conviction all along.

The sentence length. If a plea results in a sentence of one year or more — whether suspended or not — the sentence-length trigger for the aggravated-felony analysis becomes active. The difference between an 11-month sentence and a 12-month sentence, in immigration terms, can be the difference between a green card and a deportation order. A criminal defense attorney who does not practice immigration law will not negotiate with the INA sentence threshold in mind.

The charge as pled. The immigration consequence of a conviction turns on the specific offense of conviction — not the facts of what happened, but the statute the defendant pled to and what elements that statute requires. A plea to a reduced charge may or may not change the immigration consequence. That analysis is statute-specific, case-specific, and requires attorney review of the specific plea language before it is entered.

A felony DUI is not the end — but fighting it demands attorneys who understand that the fight is in two courtrooms at once. If you accept a plea offer in a felony DUI case without crimmigration review, you may be making the most consequential decision of your legal life with only half the information. That is not acceptable to us.

Why a Felony DUI Demands Attorneys Who Fight Both Courtrooms

Criminal Defense and Immigration Defense — Not Two Cases, One Fight

When you come to Novo Legal with a felony DUI, your case gets two analyses from the start. The criminal defense side evaluates the evidence: the stop, the chemical test, the prior-conviction documentation, the charge as filed, the viability of a challenge at the preliminary hearing, and what plea options exist in the specific Colorado county where your case is pending. The immigration side evaluates each of those options against your specific status — green card, DACA, visa, undocumented — and maps what each criminal outcome means for your immigration record, your naturalization timeline, your re-entry rights, and your removal risk.

Those two analyses are not handed off between attorneys. They happen in conversation, on the same file, before any recommendation is made. The path we recommend is one that accounts for both courtrooms. Every time. No handoffs. No gaps.

We have seen clients accept plea offers from well-intentioned criminal defense attorneys and discover only at a naturalization interview that the plea meant their green card was at risk. That is not acceptable to us, and it does not happen in our cases.

For the full framework of how criminal charges interact with immigration status, see our aggravated felonies and deportation analysis and our DUI and immigration in Colorado guide.

Colorado Felony Courts — Local Experience Matters

The most common venues for felony DUI cases involving this page's audience are Adams County District Court (Brighton), Arapahoe County District Court (Centennial), Jefferson County District Court (Golden), and Denver District Court. Each of these courts has its own local prosecution tendencies, its own range of typical plea offers, and its own judicial culture around sentencing in felony DUI cases.

We appear regularly in these courts. We know how prosecutors in Adams County approach prior-offense counting challenges. We know what a Jefferson County judge will and will not accept in a plea structure. We know how to present an immigration-sensitive sentencing argument to a district court judge who has probably never thought about INA sentence thresholds. That local knowledge is not a selling point — it is how we build defenses that actually work in the rooms where your case will be decided.

We also appear in federal immigration court and before USCIS. The two sides of every case are better for it.

Frequently Asked Questions — Felony DUI in Colorado

What makes a DUI a felony in Colorado?

Under C.R.S. § 42-4-1301(1)(a), a DUI or DWAI charge becomes a class 4 felony when the defendant has three or more prior qualifying convictions — DUI, DWAI, DUI per se, vehicular assault, or vehicular homicide — arising from separate and distinct criminal episodes. There is no time limit on prior convictions. A DUI from twenty years ago counts the same as one from last year.

Do out-of-state DUI convictions count toward the Colorado felony threshold?

Yes. Under C.R.S. § 42-4-1301(1)(j), Colorado counts convictions from other states, the federal government, or U.S. territories if the conduct would have constituted a qualifying offense under Colorado law. Two DUIs in New Mexico and one in Colorado, for instance, would generally count as three qualifying priors under this standard. Whether a specific out-of-state conviction qualifies requires attorney review of the particular statute of conviction.

Do DWAI convictions count as priors for the felony threshold?

Yes. DWAI — Driving While Ability Impaired — is expressly included in the list of qualifying prior convictions under C.R.S. § 42-4-1301(1)(a). A defendant with two DWAI convictions and one DUI conviction who is charged with a new DUI has three qualifying priors and faces a felony charge.

What are the penalties for a class 4 felony DUI in Colorado?

A class 4 felony in Colorado carries a general sentencing range of 2 to 6 years in the Colorado Department of Corrections, a fine of $2,000 to $500,000, and 3 years of mandatory parole following any DOC sentence under C.R.S. § 18-1.3-401. In appropriate cases, a court may sentence a felony DUI defendant to probation instead of prison; a probation sentence carries its own mandatory minimum jail condition under C.R.S. § 42-4-1307(6.5). All penalty ranges are subject to judicial discretion, the specific facts, and current statutory text confirmed by an attorney.

Can a felony DUI affect my green card?

Yes — and more seriously than a misdemeanor DUI. A felony DUI conviction creates elevated immigration risk on multiple fronts: the aggravated-felony analysis (depending on the specific charges and sentence), the CIMT analysis at the felony level, and the good moral character bar for naturalization. A green card is not a shield against a felony conviction. For the full analysis, see our how criminal charges affect your green card page.

Can a felony DUI end my DACA?

Under current DACA regulations, any felony conviction is an absolute bar to DACA eligibility. There is no discretion, no exception, and no sentence threshold. A felony DUI conviction categorically disqualifies a person from DACA — this is a different and more absolute bar than the significant-misdemeanor analysis that governs first-offense DUI. For the full DACA analysis, see our DACA and criminal charges page.

Is a felony DUI an "aggravated felony" under immigration law?

Not automatically. The immigration term "aggravated felony" has its own definition under federal law — separate from Colorado's felony classification — and the question of whether a class 4 felony DUI qualifies depends on the specific facts of the case, including the charges and sentence imposed, and the current state of federal caselaw. Under current doctrine, the standard Colorado felony DUI generally lacks a clear pathway to aggravated-felony status through the crime-of-violence route — but this analysis is fact-specific, active in the courts, and requires attorney review before any plea is entered.
