DUI Causing Death Nevada

DUI causing death in Nevada is one of the most serious criminal charges a person can face. Under NRS 484C.430, a driver who operates a vehicle while under the influence and proximately causes the death of another person faces a Category B felony carrying two to twenty-five years in prison, a mandatory fine of two thousand to five thousand dollars, and a three-year driver’s license revocation. Probation is not available — a conviction means mandatory prison time. If you or a family member has been charged, the criminal defense team at De Castroverde Law Group has the experience to evaluate the evidence, challenge the prosecution’s case, and protect your rights throughout the legal process. Our DUI defense team handles the most serious impaired driving cases in Clark County.

DUI Causing Death vs. Vehicular Homicide vs. Vehicular Manslaughter

Nevada law creates three distinct charges when a motor vehicle accident results in death. Understanding the differences between these charges is essential because the penalties, elements of proof, and long-term consequences vary dramatically. For a detailed analysis of how these charges compare, see our blog post on DUI manslaughter vs. vehicular homicide.

Charge NRS Statute Classification Prison Range Key Requirement
DUI causing death (no prior DUIs) NRS 484C.430 Category B felony 2–25 years DUI + proximate cause of death
DUI causing death (1–2 prior DUIs) NRS 484C.430 Category B felony 5–25 years DUI + death + 1–2 prior convictions
Vehicular homicide (3+ prior DUIs) NRS 484C.130 Category A felony 25 years – life DUI + death + 3+ prior DUI convictions
Vehicular manslaughter NRS 484B.657 Misdemeanor Up to 6 months Simple negligence + death (no DUI required)

DUI causing death under NRS 484C.430 applies when a person drives under the influence and that impaired driving proximately causes someone’s death. The charge does not require prior DUI convictions, but prior convictions increase the mandatory minimum sentence. Vehicular homicide Nevada under NRS 484C.130 is a separate and significantly more severe charge reserved for defendants who have three or more prior DUI convictions — regardless of when those convictions occurred. There is no lookback period, meaning a DUI from decades ago still counts. Vehicular manslaughter under NRS 484B.657 is fundamentally different because it does not require any DUI element — only simple negligence while driving that results in death. A vehicular manslaughter Las Vegas conviction is a misdemeanor, making it dramatically less severe than either DUI-related death charge.

What Prosecutors Must Prove for DUI Causing Death

To secure a conviction under NRS 484C.430, the prosecution must prove two core elements beyond a reasonable doubt. First, the defendant was driving or in actual physical control of a vehicle while under the influence of alcohol or a controlled substance, or with a blood alcohol concentration of 0.08 percent or higher. Second, the defendant’s impaired driving was the proximate cause of another person’s death.

Proximate causation is often the most contested element. The prosecution must establish that the defendant’s DUI was a substantial factor in causing the death — not merely that the defendant was impaired at the time of the accident. If an independent intervening cause such as another driver’s reckless behavior or a mechanical failure contributed to the fatality, the causation element may be challenged. This is where accident reconstruction evidence and expert testimony become critical to the defense. Understanding the full range of DUI penalties in Nevada provides important context for how this charge fits within the broader penalty framework.

Notably, DUI causing death does not require any intent to kill. The charge is based on the combination of voluntary intoxication and the resulting death. This distinguishes it from murder charges, which require malice or premeditation, and from involuntary manslaughter under NRS 200.070, which is a Category D felony carrying one to four years in prison and may apply as an alternative charge theory when the facts do not clearly support DUI-specific prosecution.

Penalties and Sentencing for DUI Causing Death in Nevada

As of January 2026, the Safe Streets and Neighborhoods Act (Assembly Bill 4) increased the maximum prison sentence for DUI causing death under NRS 484C.430. A defendant with no prior DUI convictions faces two to twenty-five years in Nevada state prison, a mandatory fine of two thousand to five thousand dollars, a three-year revocation of driving privileges, and potential restitution to the victim’s family. Probation and suspended sentences are not available under any circumstances — a convicted defendant must serve prison time.

If the defendant has one or two prior DUI convictions, the mandatory minimum increases to five years with the same twenty-five-year maximum. The fine and license revocation remain the same. For defendants with three or more prior DUI convictions from any point in their lifetime, the charge escalates to vehicular homicide under NRS 484C.130 — a Category A felony carrying twenty-five years to life in prison with parole eligibility after ten years. When an impaired driving accident causes serious harm but the victim survives, a DUI with injury charge under a related statute applies instead.

Defense Strategies for DUI Causing Death Charges

A felony DUI causing death charge demands aggressive and thorough defense. Several strategies may apply depending on the specific facts of the case.

Challenging the DUI element. The prosecution must prove impairment or an unlawful BAC. Defense attorneys challenge blood and breath test results by examining whether testing equipment was properly calibrated, whether the blood draw followed required procedures, whether the chain of custody was maintained, and whether the sample was contaminated or improperly stored. Rising blood alcohol — where the defendant’s BAC was below the legal limit while driving but rose above it by the time of testing — is another viable defense. An experienced felony DUI attorney can evaluate whether the BAC evidence is reliable.

Challenging causation. Even if the defendant was legally impaired, the defense may argue that the DUI was not the proximate cause of the death. If another driver ran a red light, if road conditions or vehicle defects contributed to the accident, or if the deceased’s own negligence was a substantial factor, the causal chain between the DUI and the death may be broken. In some cases, a sober driver would have been unable to avoid the same accident under the same conditions — which undermines the prosecution’s theory that impairment caused the fatality. Accident reconstruction experts analyze physical evidence — skid marks, vehicle damage patterns, speed calculations, and point of impact — to build or challenge the causation theory.

Expert witnesses. Fatal DUI cases frequently involve toxicologists who testify about BAC levels and impairment, accident reconstructionists who analyze the crash dynamics, and medical examiners who address the actual cause of death. The defense may retain independent experts in each of these fields to challenge the prosecution’s conclusions. De Castroverde Law Group’s criminal defense team works with qualified experts across these disciplines.

Collateral Consequences of a DUI Causing Death Conviction

Beyond prison time and fines, a DUI causing death conviction carries permanent consequences that affect virtually every area of the defendant’s life.

Record sealing is impossible. Under NRS 179.245, a conviction for DUI causing death under NRS 484C.430 can never be sealed — regardless of how much time passes, whether the sentence is completed, or whether the defendant has no other criminal history. The same permanent prohibition applies to vehicular homicide under NRS 484C.130 and to felony DUI under NRS 484C.400. This means the conviction will appear on every background check for the rest of the defendant’s life, affecting employment opportunities, housing applications, and professional licensing permanently.

DUI Court ineligibility. Nevada’s DUI Court program offers qualifying defendants an alternative to standard sentencing through intensive treatment and supervision. However, defendants charged with vehicular homicide Nevada cases are ineligible for DUI Court, and judges have discretion to exclude DUI causing death defendants depending on the circumstances.

Immigration consequences. For non-citizens, a DUI causing death conviction is classified as an aggravated felony under federal immigration law, which triggers mandatory deportation, bars future admission to the United States, and eliminates eligibility for most forms of relief including asylum and cancellation of removal. Even lawful permanent residents with decades of residency in the United States face removal proceedings following an aggravated felony conviction. Non-citizens facing this charge should consult both a criminal defense attorney and an immigration attorney immediately.

Professional license revocation. Medical professionals, attorneys, commercial drivers, teachers, real estate agents, and others who hold state-issued professional licenses face disciplinary action and potential revocation following a felony DUI conviction. The licensing board’s action is separate from the criminal case and may proceed regardless of the criminal outcome.
