The Most Serious Charge in Utah’s DUI Framework
Automobile homicide in Utah is what the State charges when a death results from impaired driving. It is prosecuted under Utah Code § 76-5-207 — a homicide statute, not a traffic statute — and it carries prison exposure measured in years or decades, not days. These cases are also unlike any other DUI matter: they involve grieving families, accident reconstruction, search warrants executed at hospital bedsides, and prosecutors under enormous public pressure. If you or a family member is under investigation or charged after a fatal crash anywhere in Utah, nothing on this page substitutes for talking to a defense attorney immediately — but understanding the charge, its degrees, and its defenses is the right place to start.
What the State Must Prove Under § 76-5-207
Automobile homicide requires the prosecution to establish three things beyond a reasonable doubt:
- Operation while impaired: the driver operated a vehicle while under the influence of alcohol or drugs, with a BAC at or above Utah’s 0.05% limit, or otherwise in violation of the DUI statute;
- A death: another person was killed; and
- Causation plus negligence: the driver caused the death while operating the vehicle in a negligent or criminally negligent manner.
Degrees: Third-Degree vs. Second-Degree Felony
The level of negligence — and the driver’s history — determines the degree:
- Third-degree felony: death caused with simple negligence while DUI — ordinary carelessness. Exposure: 0 to 5 years in prison and fines up to $5,000 plus surcharge.
- Second-degree felony: death caused with criminal negligence — a gross deviation from what a reasonable person would do — or where aggravating factors such as prior DUI-related convictions apply. Exposure: 1 to 15 years in prison and fines up to $10,000 plus surcharge.
The gap between those ranges is why the negligence element is the central battlefield in most automobile homicide cases. The difference between “drifted with traffic on a dark road” and “grossly deviated from reasonable care” can be ten years of a person’s life — and it is a question of proof, argument, and expert analysis, not a label the State gets to assign for free.
Utah also maintains a separate offense for automobile homicide involving a handheld device under § 76-5-207.5, and prosecutors sometimes charge in the alternative after crashes involving both alleged impairment and phone use. Which theory the State commits to shapes the whole defense, so charging documents in a fatality case deserve line-by-line analysis from the first day.
Related Charges After a Serious Crash
Fatal and near-fatal DUI crashes generate a cluster of charges, and the differences matter:
- DUI with serious bodily injury: when the victim survives with serious injuries, the charge is a third-degree felony DUI under § 41-6a-503.
- Aggravated offenses: depending on facts — fleeing, extreme recklessness, multiple deaths — prosecutors may pursue additional or alternative homicide theories.
- Enhancement forever after: any automobile homicide conviction makes every future DUI a felony and brings a 10-year ignition interlock restriction and long-term alcohol-restricted status.
Beyond Prison: The Full Consequence Picture
A conviction under § 76-5-207 reaches far past the prison term. Expect a lengthy driver license revocation, a 10-year ignition interlock restriction, lifetime alcohol-restricted driver status, restitution obligations to the victim’s family that can be substantial, and a permanent violent-felony record affecting employment, housing, firearm rights, and immigration status. Civil wrongful-death litigation almost always runs alongside the criminal case, which is one more reason every statement made early — to police, insurers, or on social media — must be treated as evidence in two lawsuits at once.
How These Cases Are Actually Defended
Causation is not assumed
The State must prove the defendant’s operation of the vehicle caused the death — not merely that the defendant was impaired and someone died. Fatal crashes routinely involve a second driver’s sudden movement, a pedestrian in dark clothing outside a crosswalk, road design and lighting failures, weather, or mechanical defects. Defense accident reconstruction — downloading the vehicles’ event data recorders, mapping the physical evidence, modeling speeds and sightlines — frequently tells a different story than the initial police narrative written in the first 48 hours.
The blood evidence must survive scrutiny
In fatality cases, blood is usually drawn at a hospital under a warrant obtained in the chaotic hours after the crash. Everything about that process is challengeable: the warrant application’s accuracy, the timing of the draw and retrograde extrapolation back to the time of driving, the draw procedure, chain of custody, and the lab’s analysis. Utah’s history on warrantless blood draws — including the nationally publicized 2017 University of Utah Hospital incident — makes courts attentive to these issues, and suppression motions aimed at the blood evidence can transform the case.
The negligence fight
Where the evidence of impairment holds, the degree fight remains: criminal negligence is a demanding standard, and facts that look damning in a probable cause statement often soften under cross-examination. Reducing a second-degree charge to a third-degree conviction, or defeating the homicide count while resolving a DUI, are real outcomes in these cases.
What to Expect From the Process
Automobile homicide cases are filed in district court and move like the serious felonies they are: bail arguments with victim’s-family input, a preliminary hearing where causation and negligence evidence gets its first test, months of expert discovery, and intense negotiation shaped by the strength of the science on both sides. Sentencing, if it comes to that, is governed by Utah’s indeterminate system — the judge imposes the statutory range and the Board of Pardons and Parole decides actual time served, which makes mitigation preparation and a credible record of accountability enormously consequential. Experienced criminal defense counsel manages both tracks: the courtroom fight and the human one.
Compassion and Defense Are Not Opposites
Most people charged with automobile homicide are not criminals in any ordinary sense — they are people carrying unbearable grief of their own after the worst night of their lives. Insisting that the State prove its case, that the blood evidence be lawful, and that the negligence label be accurate is not disrespect to the person who died; it is what the Constitution requires before the State takes years of someone’s liberty.

Frequently Asked Questions
What is automobile homicide under Utah law?
Automobile homicide, Utah Code 76-5-207, is causing another person's death while driving under the influence of alcohol or drugs and operating the vehicle negligently. It is a third-degree felony when committed with simple negligence and a second-degree felony when committed with criminal negligence or with aggravating factors such as prior DUI convictions.
How much prison time does automobile homicide carry in Utah?
A third-degree felony carries zero to five years in prison; a second-degree felony carries one to fifteen years. Utah uses indeterminate sentencing, so the Board of Pardons and Parole determines actual time served within the statutory range the judge imposes.
What is the difference between simple and criminal negligence?
Simple negligence is ordinary carelessness, the failure to use reasonable care. Criminal negligence is a gross deviation from the standard of care a reasonable person would observe. Because the difference separates a 0-to-5-year felony from a 1-to-15-year felony, the negligence element is usually the most contested issue in the case.
What if the victim survived but was seriously hurt?
A DUI that proximately causes serious bodily injury to another person is charged as a third-degree felony DUI under Utah Code 41-6a-503 rather than automobile homicide. These cases involve many of the same defenses, including causation, accident reconstruction, and blood evidence challenges.
Should I talk to investigators after a fatal crash?
Not before speaking with a defense attorney. Fatal crash investigations begin immediately, statements made in shock are used later, and critical defense evidence disappears within days.
