Key Takeaways
What to Know About Felony DUI Charges in Colorado
The points below summarize when a DUI becomes a felony in Colorado, the charges that apply, and the penalties involved.
- In Colorado, most first, second, and third DUI offenses are charged as misdemeanors. A DUI is charged as a felony only when specific legal conditions are met.
- A fourth or subsequent DUI in Colorado is a Class 4 felony when the driver has three or more prior convictions for DUI, DUI per se, DWAI, vehicular assault, or vehicular homicide. Out-of-state convictions count toward this total.
- A DUI that causes serious bodily injury is charged as vehicular assault, a Class 4 felony in Colorado. A DUI that causes a death is charged as vehicular homicide, a Class 3 felony punishable by up to 12 years in prison.
- A Class 4 felony DUI conviction in Colorado carries 2 to 6 years in prison, fines up to $500,000, a mandatory 3-year parole period, and the loss of certain civil rights, including firearm ownership.
- Felony DUI convictions in Colorado generally cannot be expunged or sealed, so a felony DUI stays on a person’s criminal record permanently.

Schedule a ConsultationFelony DUI Law in Colorado
Colorado’s felony DUI law went into effect in 2015. Prior to that, all DUI charges were treated as misdemeanors unless someone was seriously injured or killed. The change in law allows prosecutors to seek felony charges once a driver accumulates three prior convictions for impaired driving offenses.
The law does not require that prior convictions be from Colorado. Out-of-state convictions also count as long as the conduct would be considered a DUI under Colorado law. This broad definition catches many people off guard.
When Does a DUI Become a Felony?
Under Colorado law, the prosecutor can elevate a DUI to a felony if the facts of the case meet certain thresholds. This is important for anyone wondering if a DUI is a felony in Colorado.
1. It Is Your Fourth or Subsequent DUI
Do you have three or more prior convictions for any of the following?
- DUI,
- DUI per se,
- DWAI,
- Vehicular assault, or
- Vehicular homicide.
If you have three or more of these convictions from anywhere in the United States, the prosecutor can charge your fourth DUI as a Class 4 felony in Colorado. This holds true regardless of how much time has passed between offenses.
Even if no one was injured and your BAC was only slightly over the legal limit, the fourth offense rule applies automatically.
2. The DUI Involves Serious Bodily Injury or Death
A DUI can also become a felony if it causes harm to another person. These offenses are charged separately under Colorado’s vehicular assault and vehicular homicide statutes.
- Vehicular assault. Causing serious bodily injury while driving under the influence is a Class 4 felony.
- Vehicular homicide. Causing the death of another person while impaired is a Class 3 felony, punishable by up to 12 years in prison.
These charges are among the most serious DUI-related crimes in Colorado. You would be wise to seek immediate legal representation if the State charges you with such an offense.
3. You Have Prior Felony DUI Convictions
If you already have a felony DUI conviction, any new DUI charge may be prosecuted more aggressively. The court can consider your full criminal history when determining sentencing.
In these situations, prosecutors may be less inclined to offer advantageous plea deals, and judges may impose maximum sentences. Having an experienced defense lawyer can make a meaningful difference.
Penalties for a Felony DUI in Colorado
The penalties for a felony DUI in Colorado are significantly more severe than those for a misdemeanor offense. A felony conviction can affect many areas of your life for years to come. Some of the potential penalties include the following:
- Prison time. A felony DUI conviction can lead to a prison sentence of 2 to 6 years if charged as a Class 4 felony.
- Fines. You may face fines of up to $500,000, depending on the circumstances of your case.
- Parole. Upon release from prison, there is a mandatory parole period of 3 years.
- Loss of civil rights. A felony conviction can result in the loss of certain rights, including the right to own or possess firearms.
- Felony record. A felony DUI conviction will remain on your criminal record. This can negatively influence job applications, rental housing approvals, and other aspects of everyday life.
Unlike misdemeanor DUI convictions, felony DUI convictions in Colorado typically cannot be expunged or sealed, which makes early legal intervention critical.
