If you’ve been arrested for DUI in Colorado, you’re probably wondering if a DUI is a felony. The answer depends on several factors, including your prior record and whether the incident caused injury or death. Below, we break down when a DUI becomes a felony in Colorado, what penalties you could face, and why hiring an experienced Denver DUI lawyer can make all the difference.
When Is a DUI a Felony in Colorado?
Most first and second DUI offenses in Colorado are charged as misdemeanors. However, there are several scenarios in which a DUI becomes a felony, carrying far more severe penalties.
1. Fourth or Subsequent DUI – Class 4 Felony
Under Colorado Revised Statutes § 42-4-1301, a fourth DUI offense—or any DUI after three prior convictions for DUI, DWAI, vehicular assault, or vehicular homicide—is automatically classified as a Class 4 felony. This applies even if the current incident didn’t involve an accident or injury.
Potential penalties:
- 2 to 6 years in Colorado state prison (plus 3 years parole)
- Up to $500,000 in fines
- Mandatory substance abuse treatment
- Revoked driver’s license
2. DUI Causing Serious Injury – Vehicular Assault
If you’re accused of driving under the influence and causing serious bodily injury to another person, prosecutors may charge you with vehicular assault, a felony under C.R.S. § 18-3-205.
Penalties may include:
- Class 4 felony charges
- 2 to 6 years in prison
- Significant fines
- Restitution to the victim
- Long-term loss of driving privileges
3. DUI Causing Death – Vehicular Homicide
If a DUI results in the death of another person, the charge becomes vehicular homicide under C.R.S. § 18-3-106. This is one of the most serious DUI-related felonies and can result in substantial prison time.
Penalties may include:
- Class 3 felony
- 4 to 12 years in state prison (with aggravated sentencing up to 24 years)
- Up to $750,000 in fines
- Permanent criminal record
Misdemeanor vs. Felony DUI in Colorado
Understanding the difference is crucial. A misdemeanor DUI typically applies to first or second offenses with no injury involved. These cases often result in county jail time, fines, probation, community service, and license suspension. A felony DUI, on the other hand, puts you at risk of prison time, higher fines, and long-term consequences that can affect your job, housing, and civil rights. Even a misdemeanor DUI can carry heavy penalties, but a felony DUI can change your life forever.
