Is There a DUI Causing Death Law in Arizona?
Quick answer: In Arizona there is no single “DUI causing death” statute. A fatal impaired-driving crash is charged as negligent homicide, manslaughter, or second-degree murder depending on the driver’s mental state, with aggravated DUI (A.R.S. § 28-1383) stacked on top. Exposure ranges from 4 years to 25 years. The defense attacks the stop, the blood draw, causation, and the charge level.
Key Takeaways
- A fatal DUI crash is charged as negligent homicide, manslaughter, or second-degree murder, plus aggravated DUI (A.R.S. § 28-1383).
- Exposure depends on the homicide charge: 4–8 years (negligent homicide) up to 10–25 years (second-degree murder), most of it flat time.
- The State uses a high BAC or prior DUIs to push the charge up toward second-degree murder; we fight to keep it at manslaughter or lower.
- Blood-draw, warrant, chain-of-custody, and rising-BAC challenges can undercut the DUI core of the entire case.
- The strongest defenses attack causation, the charge level, and the State’s reconstruction and toxicology.
- Your case is handled by a full team of attorneys, not associates, including Michael Tamou, available 24/7 at 623-321-4699.

Arizona Homicide Law, Charge by Charge
After a fatal crash, the charge depends almost entirely on the driver’s mental state. Statutes link to azleg.gov.
Vehicular Manslaughter, A.R.S. § 13-1103
Arizona has no separate “vehicular manslaughter” statute, a fatal crash caused by reckless driving is charged as vehicular manslaughter under A.R.S. § 13-1103. “Recklessly” means the driver was aware of and consciously disregarded a substantial and unjustifiable risk, such as extreme speeding, street racing, or running red lights. Manslaughter is a Class 2 felony, and because a vehicle is a dangerous instrument it is a dangerous offense carrying flat-time prison.
Negligent Homicide, A.R.S. § 13-1102
When a driver causes a death through criminal negligence, a failure to perceive a substantial risk that a reasonable person would have perceived, the charge is negligent homicide, a Class 4 felony. The distinction from manslaughter is the mental state: negligence (should have known) versus recklessness (knew and disregarded). Persuading the State or a jury that the conduct was negligent rather than reckless can cut the sentence dramatically, and is one of the most important defense goals.
Second-Degree Murder, A.R.S. § 13-1104
A fatal crash can be charged as second-degree murder when the State alleges the driver acted with “extreme indifference to human life.” This typically arises with a very high BAC, prior DUI convictions, wrong-way driving, or extreme speed. Second-degree murder is a Class 1 felony with a 10 to 25 year range under A.R.S. § 13-710. Defeating the “extreme indifference” theory to move the case down to manslaughter is often the central battle.
DUI Causing Death & Aggravated DUI, A.R.S. § 28-1383
When alcohol or drugs are involved in a fatal crash, the State frequently stacks aggravated DUI charges on top of the homicide count, and uses impairment to push the homicide charge higher. Challenging the stop, the blood draw, the chain of custody, and rising-BAC science is therefore central to the entire defense, not just the DUI.
Endangerment & Leaving the Scene, A.R.S. §§ 13-1201, 28-661
Surviving occupants and nearby drivers can support endangerment counts (A.R.S. § 13-1201) for each person placed at substantial risk. Failing to stop and remain at a crash involving death or serious injury is a separate, serious felony under A.R.S. § 28-661, often charged alongside the homicide count. Reducing the overall count structure is part of the defense.
What the State Must Prove for DUI Causing Death
To convict you of DUI Causing Death under A.R.S. § 28-1383 / 13-1103, the prosecutor must prove every one of these elements beyond a reasonable doubt. If even one fails, the charge fails.
- 1Impairment (the DUI). You were driving under the influence, with a BAC of .08 or more, or impaired to the slightest degree by alcohol or drugs.
- 2Causation. Your driving, not another driver or an intervening event, actually caused the death.
- 3A resulting death. Another person died as a result of the crash.
- 4The homicide mental state. Negligence, recklessness, or extreme indifference, which determines whether the charge is negligent homicide, manslaughter, or second-degree murder.
Examples of Conduct Charged as DUI Causing Death
- A fatal crash with a driver BAC over .08
- A fatal crash involving drug or prescription-medication impairment
- A high-BAC or repeat-DUI fatal crash charged as second-degree murder
- A wrong-way or extreme-speed impaired-driving collision
Negligence vs. Recklessness vs. Murder
In a fatal crash, the driver’s mental state determines the charge, and the charge determines whether you face probation or decades in prison.
| Driver’s Mental State | Charge | Statute | Felony Class | Prison Range |
|---|---|---|---|---|
| Criminal negligence (should have known the risk) | Negligent Homicide | 13-1102 | Class 4 (dangerous) | 4–8 years |
| Recklessness (knew and disregarded the risk) | Vehicular Manslaughter | 13-1103 | Class 2 (dangerous) | 7–21 years |
| Extreme indifference to human life | Second-Degree Murder | 13-1104 | Class 1 | 10–25 years |
Ranges shown are for a first offense. Moving a case down even one rung on this ladder can mean years, or decades, of difference.
Penalties for DUI Causing Death in Arizona
A fatal DUI is sentenced under whichever homicide charge the State proves, negligent homicide (4–8 years), manslaughter (7–21 years flat), or second-degree murder (10–25 years), with aggravated DUI penalties added on top. The charge level decides everything.
Class 4
Negligent Homicide
Class 2
Vehicular Manslaughter
Class 1
Second-Degree Murder
| Charge | Felony Class | Minimum | Presumptive | Maximum |
|---|---|---|---|---|
| Negligent Homicide | Class 4 (dangerous) | 4 years | 6 years | 8 years |
| Vehicular Manslaughter | Class 2 (dangerous) | 7 years | 10.5 years | 21 years |
| Second-Degree Murder | Class 1 | 10 years | 16 years | 25 years |
⚠ “Dangerous Offense” Means Flat Time
A dangerous-offense designation under A.R.S. § 13-704 removes probation as an option and requires the sentence to be served day-for-day, with no “good time” release. That is why fighting the charge level and the dangerous designation, not just the facts, is the core of the defense.
Collateral Consequences
Beyond prison, a vehicular homicide conviction brings driver’s license revocation, a permanent felony record, loss of firearm and civil rights, immigration consequences for non-citizens, and almost always a parallel civil wrongful-death lawsuit from the victim’s family. Coordinating the criminal defense with that civil exposure matters from day one.
Common Defenses in Arizona Vehicular Homicide Cases
The State must prove your driving caused the death and that you acted with a culpable mental state. Each of those is a place to fight.
Attacking Causation & the Crash
Lack of Causation. The State must prove your driving, not another factor, caused the death. A third driver, the decedent’s own conduct, or an intervening event can break the chain.
Faulty Accident Reconstruction. Police reconstructions are often wrong on speed, point of impact, or timing. Our independent experts frequently reach the opposite conclusion.
Unavoidable Accident. If a reasonable driver could not have prevented the crash, there is no crime, only a tragedy.
Mechanical Failure or Road Conditions. Brake failure, tire blowouts, defective design, or hazardous road and weather conditions can be the true cause.
Sudden Medical Emergency. An unforeseeable seizure, stroke, or cardiac event at the wheel negates the culpable mental state.
Attacking Mental State & the Evidence
Accident, Not Recklessness. Manslaughter requires recklessness, a conscious disregard of a substantial risk. Ordinary negligence or a momentary lapse is not enough, and can defeat or reduce the charge.
Fighting the Charge Level. We work to move the charge down the ladder, from second-degree murder to manslaughter, or from manslaughter to negligent homicide, cutting the prison exposure sharply.
Blood Draw & BAC Challenges. Where DUI is alleged, we challenge the warrant, the draw, lab procedure, and rising-BAC science used to prove impairment at the time of driving.
Unlawful Stop, Search & Statements. Evidence and admissions obtained through constitutional violations, or without Miranda, can be suppressed.
Event Data Recorder Disputes. “Black box” data can be misread or incomplete. We bring in EDR analysts to test what it really shows.
After reviewing your case, we will explain which defenses apply and the best path forward.
CALL 623-321-4699The Experts We Bring to the Table
The State builds fatal-crash cases with police reconstructionists and crime labs. We answer with the same caliber of specialists, so the government’s science gets challenged by people who do this for a living.
Accident Reconstructionists
Crash Dynamics
Independently analyze speed, braking, point of impact, sight lines, and timing, often reaching conclusions that contradict the police report and break the State’s causation theory.
Forensic Toxicologists
BAC & Impairment
Challenge blood draws, lab protocol, and rising-BAC science used to allege impairment at the time of driving, central to fighting DUI-homicide and murder theories.
Event Data Recorder Analysts
“Black Box” Data
Extract and interpret the vehicle’s EDR data, speed, throttle, braking, and seatbelt use, and expose where the State has misread or cherry-picked it.
Biomechanical Engineers
Injury Causation
Assess whether the injuries and forces are consistent with the State’s account of how the crash happened, and who was driving.
Medical Examiners & Pathologists
Cause of Death
Provide independent review of the autopsy and cause of death, including pre-existing conditions and alternative causes the State overlooked.
Human Factors Experts
Perception & Reaction
Evaluate driver perception-reaction time, visibility, distraction, and whether a reasonable driver could have avoided the collision at all.
What to Do If You’re Under Investigation
What you do in the first hours after a deadly crash can decide whether you are charged, and with what.
Do Not Admit Fault
At the scene, to police, or to anyone, do not apologize or speculate about what happened. “I’m sorry” can be used as an admission. Provide license and registration and otherwise stay silent.
Do Not Consent to a Blood Draw Without Counsel
Police often seek blood after a fatal crash. You can require a warrant. Anything you say about drinking or drugs will be used to push the charge higher.
Preserve the Vehicle & Black Box
Do not repair or release your vehicle, it holds event-data-recorder evidence critical to reconstruction. Counsel will move to preserve it immediately.
Write Down What You Remember
As soon as you safely can, note road and weather conditions, the other driver’s actions, witnesses, and the sequence of events. Memory fades fast.
Do Not Post on Social Media
Photos, check-ins, and comments are all evidence. Set accounts to private and post nothing about the crash.
Call Tamou Law Group at 623-321-4699
The earlier we are involved, the more we can do, preserving evidence, retaining reconstructionists, and engaging prosecutors before charges are filed. Available 24/7.
Mitigation: Shaping the Outcome
In a fatal-crash case, mitigation can move a charge down the homicide ladder or off the dangerous-offense range entirely.
We build mitigation packages that include a complete personal history, lack of prior record, employment and family ties, genuine remorse, counseling and treatment records where substance use is involved, and a proportionality review showing reduced charges and sentences in comparable Arizona cases. Presented early and credibly, mitigation can be the difference between a negligent-homicide probation outcome and a decade of flat time.
The Pre-Charge Window
Fatal-crash investigations often take weeks or months. That window is your best opportunity.
While detectives are still investigating, we can conduct our own reconstruction, preserve evidence, and present prosecutors with the science before they decide what to charge, sometimes the difference between negligent homicide and manslaughter, or between charges and no charges at all. The sooner Michael Tamou is involved, the more leverage we have.

Protecting Your Freedom When the Stakes Could Not Be HigherA Proven Defense Process for Arizona Fatal-Crash Cases
- Challenge Causation & Recklessness
- Reduce the Charge Level & Prison Exposure
- Build an Independent Reconstruction
A vehicular homicide charge is among the most serious a person can face in Arizona. Because a vehicle is treated as a dangerous instrument, manslaughter becomes a dangerous offense, meaning flat-time prison with no probation and no early release. The difference between negligent homicide, manslaughter, and second-degree murder, often years or decades, comes down to proving the driver’s state of mind.
When you work with Tamou Law Group, you get a team that includes former prosecutors and law enforcement officers who have built and investigated fatal-crash cases. We bring in our own accident reconstructionists, toxicologists, and event-data-recorder analysts to test the State’s theory before it ever reaches a jury.
A fatal crash is not automatically a crime. Tragic accidents happen without recklessness, and the State must prove a culpable mental state beyond a reasonable doubt. We force them to, with independent science, not assumptions.

623-321-46991 Immediate Response & Scene Preservation
Call before you speak to police. We move fast to preserve the vehicle, the event data recorder (“black box”), skid and scene evidence, and witness accounts before they disappear or degrade.
2 Independent Accident Reconstruction
We retain our own reconstructionists to analyze speed, point of impact, sight lines, and timing, often contradicting the police report and showing the crash was unavoidable or caused by another factor.
3 Attack Causation & Mental State
The State must prove your driving caused the death and that you acted recklessly, not merely negligently. We challenge both, the heart of reducing or defeating a manslaughter charge.
4 Toxicology & DUI Challenges
Where alcohol or drugs are alleged, we challenge blood draws, rising-BAC science, lab procedure, and impairment evidence that the State uses to push the charge toward second-degree murder.
5 Mitigation & Trial Readiness
We prepare every case for trial while pursuing charge reductions and mitigation. If resolution is the right path, we fight to move the charge down the homicide ladder and off flat-time exposure.

Arizona Vehicular Manslaughter FAQs
Common questions about fatal-crash charges, penalties, and defenses in Arizona.
Is there a DUI causing death law in Arizona?
There is no single statute. A fatal impaired-driving crash is charged as negligent homicide (A.R.S. 13-1102), manslaughter (A.R.S. 13-1103), or second-degree murder (A.R.S. 13-1104) depending on the driver’s mental state, with aggravated DUI (A.R.S. 28-1383) charged on top.
Can a fatal DUI be charged as murder in Arizona?
Yes. With a very high BAC, prior DUIs, or wrong-way driving, the State may allege extreme indifference to human life and charge second-degree murder (10 to 25 years). Defeating that theory to reduce it to manslaughter is often the central goal.
What are the penalties for a fatal DUI in Arizona?
They depend on the homicide charge proved: negligent homicide is 4 to 8 years, manslaughter 7 to 21 years (flat time), and second-degree murder 10 to 25 years, with aggravated DUI penalties added on top.
Is a fatal DUI a dangerous offense with flat time?
When charged as manslaughter, yes, because the vehicle is a dangerous instrument, so prison is mandatory and served day-for-day with no early release. The exact exposure tracks the homicide charge level.
Can the DUI or blood test be challenged in a fatal-crash case?
Yes, and it is central to the defense. We challenge the stop, the warrant, the blood draw, chain of custody, and rising-BAC science. Undercutting the DUI core weakens the entire homicide case.
What if drugs or prescription medication, not alcohol, were involved?
Arizona’s DUI law covers impairment by any drug, including prescription medication. The same homicide framework applies, and we challenge the impairment evidence and whether it actually caused the crash.
Can a fatal DUI charge be reduced or dismissed?
Yes. Through challenges to causation, the charge level (murder down to manslaughter), and suppression of an unlawful stop, search, or blood draw, the charge can be reduced or, where causation fails, dismissed.
Will I lose my driver’s license?
Aggravated DUI carries a license revocation through the MVD that is separate from the criminal case. We address both the criminal exposure and the license consequences.
Will the victim’s family sue me too?
Usually, yes. A fatal crash typically triggers a civil wrongful-death lawsuit in addition to the criminal case, so coordinated defense matters.
Should I consent to a blood draw or talk to police?
No. You can require a warrant for a blood draw, and you should politely decline questions and ask for a lawyer. Do not admit to drinking or to fault.
Will I get a real attorney or a junior associate?
At many large firms the name on the door is a figurehead and your case goes to a rotating associate. At Tamou Law Group your defense is handled by a full team of experienced attorneys, not associates, including founding attorney Michael Tamou. Call 623-321-4699, 24/7.
