A vehicular homicide sentence in Colorado runs from 2 to 12 years in prison, with the exact range turning on whether the driving was reckless or involved alcohol or drugs. Reckless vehicular homicide is a Class 4 felony punishable by 2 to 6 years. DUI vehicular homicide is a Class 3 felony punishable by 4 to 12 years. Both carry three years of mandatory parole after release, fines reaching into the hundreds of thousands of dollars, mandatory restitution to the victim’s family, and a driver’s license revocation of at least one year.1Justia.

Reckless Versus DUI: Why the Classification Decides the Sentence
Colorado’s vehicular homicide statute splits fatal driving into two categories, and the gap between them is substantial.2Justia. Colorado Code 18-3-106 – Vehicular Homicide
Reckless vehicular homicide is a Class 4 felony. The prosecution has to prove you drove in a way that consciously ignored a serious risk of killing someone. For offenses committed on or after July 1, 2020, the presumptive prison range is 2 to 6 years in the Department of Corrections.
DUI vehicular homicide is a Class 3 felony and a strict liability crime. The prosecution does not have to show you intended harm or even that you were driving poorly. If you were under the influence of alcohol, drugs, or both, and your driving caused someone’s death, the elements are met.2Justia. Colorado Code 18-3-106 – Vehicular Homicide The presumptive range is 4 to 12 years.
Within either window, the judge weighs the circumstances: speed, degree of impairment, whether passengers were in the car, whether you fled the scene, your criminal history. Most sentences land somewhere inside the range rather than at the edges, but every case turns on its facts.
How Blood Alcohol Readings Shape the Charge
Because the Class 3 version carries roughly double the prison time, blood alcohol concentration at the time of the crash becomes central evidence. The statute spells out what different readings mean:
- 0.05 or below: the law presumes you were not under the influence of alcohol.
- Above 0.05 but below 0.08: the BAC can be weighed with other evidence but creates no presumption on its own.
- 0.08 or above: the court may infer you were under the influence.3Colorado Revised Statutes. Colorado Code 18-3-106 – Vehicular Homicide
A BAC of 0.08 or higher does not guarantee a Class 3 conviction, but the permissible inference works heavily in the prosecution’s favor. Drug impairment follows a similar analysis without the numeric thresholds, with prosecutors relying on blood tests, officer observations, and expert testimony.
Enhancements That Push the Sentence Higher
Several statutory mechanisms let a judge impose a sentence above the normal presumptive maximum. Colorado courts use them regularly in vehicular homicide cases.
Flight From a Felony
If you were fleeing another felony when the fatal crash occurred, the court must sentence you to at least the midpoint of the presumptive range and can go as high as twice the maximum. For a Class 3 DUI vehicular homicide, that means a floor of 8 years and a ceiling of 24. For a Class 4 reckless vehicular homicide, the floor is 4 years and the ceiling is 12.1Justia. Colorado Code 18-1.3-401 – Felonies Classified – Presumptive Penalties
Pregnant Victim
If the victim was pregnant and you knew or reasonably should have known, the same enhanced range applies: at least the midpoint of the presumptive range, up to twice the maximum. Vehicular homicide is explicitly listed among the offenses that trigger this enhancement.1Justia. Colorado Code 18-1.3-401 – Felonies Classified – Presumptive Penalties
Crime of Violence
When vehicular homicide qualifies as a crime of violence under C.R.S. § 18-1.3-406, the court must sentence under that statute’s mandatory provisions instead of the standard presumptive ranges. The sentencing floor rises substantially, and probation is off the table.1Justia. Colorado Code 18-1.3-401 – Felonies Classified – Presumptive Penalties
Aggravated Range for People on Supervision
If you were on parole, on probation, or had escaped from a correctional facility at the time of the offense, the court can sentence in the aggravated range, which allows up to twice the presumptive maximum. For a Class 3 DUI vehicular homicide, the ceiling reaches 24 years. The judge must state the reasons for the aggravated sentence on the record.
Multiple Deaths in One Crash
When a single crash kills more than one person, the court can impose consecutive sentences for each death. In a 2025 Colorado Supreme Court case, a defendant convicted of DUI vehicular homicide received consecutive prison terms totaling 24 years.
Mandatory Parole After Release
Prison time is not the end. Every person released from the Department of Corrections after a vehicular homicide conviction must serve a mandatory parole period. For offenses committed on or after July 1, 2020, both the Class 3 and the Class 4 versions carry three years of mandatory parole.1Justia. Colorado Code 18-1.3-401 – Felonies Classified – Presumptive Penalties For offenses committed between July 1, 1993, and June 30, 2018, the Class 3 mandatory parole period was 5 years rather than 3, which matters for anyone sentenced under an older version of the statute.
Neither the court nor the defendant can waive mandatory parole. It begins the day you walk out of prison. Violating parole conditions can send you back to finish the remaining term behind bars. The state parole board does have authority to discharge someone early if it finds the person sufficiently rehabilitated, but that is the board’s call.
Fines and Restitution
Financial penalties come in two forms, and both can be heavy.
Fines ranges run from $2,000 to $500,000 for a Class 4 felony and from $3,000 to $750,000 for a Class 3.1Justia. Colorado Code 18-1.3-401 – Felonies Classified – Presumptive Penalties Anyone with two or more prior felony convictions cannot receive a fine instead of incarceration; for those defendants, a fine can only be added on top of prison.
Restitution is separate and mandatory. Colorado law requires every felony conviction to include a restitution determination, and the court cannot skip the step. In a vehicular homicide case, the judge must order restitution for financial losses caused by the crime: medical bills incurred before the victim’s death, funeral costs, insurance deductibles, lost wages, travel expenses the family incurs to attend court, and wages the family loses from participating in the prosecution.4Justia. Colorado Code 18-1.3-603 – Order of Restitution The only way a court avoids an order is to find on the record that no victim suffered any financial loss, which in a fatal crash is essentially impossible.
Driver’s License Revocation
A vehicular homicide conviction triggers an automatic driver’s license revocation of at least one year. The Colorado Department of Revenue must revoke the license immediately upon receiving the conviction record, and the rule applies to both the reckless and DUI forms of the offense.5Justia. Colorado Code 42-2-125 – Mandatory Revocation of License and Permit
The one-year minimum is often academic. Anyone sentenced to prison will be incarcerated longer than a year, and the revocation runs during that time. Reinstatement after release requires meeting whatever conditions the department imposes, which can include SR-22 insurance filings and reinstatement fees.
Is Probation Possible?
Colorado judges have general authority to suspend a sentence and grant probation when it serves the interests of the public and the defendant. Vehicular homicide is not categorically excluded under the standard presumptive sentencing scheme, but probation is uncommon in practice, particularly for DUI-related cases where the presumptive minimum is already four years in prison.1Justia. Colorado Code 18-1.3-401 – Felonies Classified – Presumptive Penalties
Probation disappears entirely if the offense qualifies as a crime of violence or if you were fleeing another felony at the time of the crash. In those scenarios the mandatory minimum prison term eliminates a probation-only outcome. Outside those enhanced scenarios probation remains technically available but difficult to secure.
When the Charge Is Vehicular Assault Instead
If reckless or impaired driving causes serious bodily injury rather than death, the charge is vehicular assault under C.R.S. § 18-3-205, not vehicular homicide. Reckless vehicular assault is a Class 5 felony carrying 1 to 3 years in prison. DUI vehicular assault is a Class 4 felony carrying 2 to 6 years. If a victim who initially survived later dies from their injuries, the charge can be upgraded to vehicular homicide. The distinction between the two offenses comes down entirely to outcome, not conduct.
