Understanding Vehicular Manslaughter While Intoxicated
When someone dies as a result of a DUI accident in Nevada County, you can be charged with one of several homicide offenses under California law. These are not simple felony DUI charges—they are homicide prosecutions that will change your life forever if you're convicted.
The Two Types of Vehicular Manslaughter While Intoxicated
California Penal Code Section 191.5 creates two separate offenses based on the degree of negligence involved:
Penal Code § 191.5(a): Gross Vehicular Manslaughter While Intoxicated
This is the more serious offense. To convict you, prosecutors must prove beyond reasonable doubt that:
- You drove a vehicle while under the influence of alcohol, drugs, or both
- While DUI, you also committed an illegal act or failed to perform a legal duty
- You committed that act or omission with gross negligence
- Your grossly negligent conduct caused another person's death
Gross Negligence Defined: Acting in a reckless way that creates a high risk of death or great bodily injury, AND a reasonable person would have known the conduct was dangerous. This goes beyond simple carelessness—it requires reckless disregard for human life.
Penalties: 4, 6, or 10 years in state prison
Penal Code § 191.5(b): Vehicular Manslaughter While Intoxicated
This is the lesser offense, though still extremely serious. Prosecutors must prove:
- You drove a vehicle while under the influence of alcohol, drugs, or both
- While DUI, you also committed an illegal act or failed to perform a legal duty
- You committed that act or omission with ordinary negligence
- Your negligent conduct caused another person's death
Ordinary Negligence Defined: Acting in a way that a reasonably careful person would not act in a similar situation. This is a much lower standard than gross negligence.
Penalties: 16 months, 2 years, or 4 years in state prison
The Critical Difference: Gross vs. Ordinary Negligence
The distinction between gross negligence and ordinary negligence can mean the difference between 4 years in prison and 10 years in prison—a 6-year difference that will define the next decade of your life.
Examples of conduct that may constitute gross negligence:
- Driving at extremely high speeds while intoxicated (80+ mph in a 45 mph zone)
- Weaving in and out of traffic at high speed
- Running multiple red lights or stop signs while DUI
- Driving the wrong way on a highway or freeway
- Evading police while intoxicated
- Racing while under the influence
- Extremely high BAC (.15% or higher) combined with dangerous driving
Examples of conduct that may constitute only ordinary negligence:
- Driving at or slightly above the speed limit while DUI
- Making a single traffic violation (running one red light, failing to yield once)
- Driving with BAC just over .08% without other dangerous conduct
- Momentary inattention or misjudgment while intoxicated
One of my primary defense strategies is arguing that even if you were negligent, your conduct did not rise to the level of gross negligence. This can reduce your prison exposure from 10 years to 4 years—and potentially make you eligible for probation.
| Charge | Statute | Negligence Required | Prison Sentence |
|---|---|---|---|
| Gross Vehicular Manslaughter While Intoxicated | PC § 191.5(a) | Gross negligence (reckless disregard) | 4, 6, or 10 years state prison |
| Vehicular Manslaughter While Intoxicated | PC § 191.5(b) | Ordinary negligence | 16 months, 2, or 4 years state prison |
| Watson Murder (Second Degree) | PC § 187 | Implied malice (conscious disregard) | 15 years to life in state prison |
⚠️ WATSON MURDER: 15 YEARS TO LIFE
If you have a prior DUI conviction and received a "Watson advisement" during sentencing, prosecutors can charge you with second-degree murder instead of manslaughter if someone dies in a subsequent DUI accident.
- What is a Watson advisement? A warning given during prior DUI sentencing that driving under the influence is extremely dangerous to human life, and that if you kill someone while DUI in the future, you can be charged with murder
- Implied malice: With a Watson advisement on record, prosecutors argue you had implied malice—you knew driving drunk could kill someone but did it anyway, showing conscious disregard for human life
- Sentence: Second-degree murder carries 15 years to life in state prison—meaning you'll serve at least 15 years before even becoming eligible for parole
- Parole hearing: Even after 15 years, the parole board may deny release, meaning you could spend the rest of your life in prison
- Strike conviction: Murder counts as a serious and violent felony "strike" under California's Three Strikes law
Defending against Watson murder charges requires attacking the validity of the prior DUI conviction, challenging whether you actually received proper Watson advisement, and presenting evidence negating implied malice.
Penalties and Consequences
Beyond prison time, vehicular manslaughter while intoxicated convictions carry devastating collateral consequences that will affect you for the rest of your life.
Criminal Penalties
Prison Sentences
- PC 191.5(b): 16 months, 2, or 4 years in state prison
- PC 191.5(a): 4, 6, or 10 years in state prison
- Watson Murder: 15 years to life in state prison
- Reality: Judges typically impose upper-term sentences in vehicular manslaughter cases given the loss of life involved
Additional Enhancements
- Multiple deaths: Each additional death can add 4-6 years consecutive
- Surviving victims with injuries: +1-6 years per injured survivor
- Prior DUI convictions: Can increase sentence within the statutory range

License Consequences
- Lifetime driver's license revocation possible
- Minimum 3-5 year revocation more typical
- May eventually become eligible for restricted license after serving time
Life-Altering Collateral Consequences
- Permanent felony record: Homicide conviction follows you forever

- Professional licenses: Permanent revocation for doctors, lawyers, nurses, contractors, real estate agents
- Housing barriers: Nearly impossible to find housing with homicide conviction
- Loss of gun rights: Permanent prohibition on firearm ownership
- Immigration consequences: Deportation is virtually certain for non-citizens
- Parental rights: Custody and visitation severely restricted
- Social stigma: Labeled as someone who killed another person
- Emotional trauma: Living with the knowledge you caused someone's death
- Victim's family: Potential harassment and threats from victim's family and community
Defense Strategies for Vehicular Manslaughter
Defending vehicular manslaughter while intoxicated charges requires a sophisticated, multi-layered approach. These are homicide cases, and prosecutors will aggressively pursue maximum penalties. However, numerous defense strategies can result in reduced charges, shorter sentences, or even acquittal.
Defense Strategy 1: Challenge Causation
Prosecutors must prove beyond a reasonable doubt that YOUR conduct caused the death. Causation is often the weakest element in these cases and provides powerful defense opportunities:
Victim's Conduct Caused the Death
- Victim ran red light or stop sign: If the deceased violated traffic laws causing the collision, you may not be the proximate cause
- Victim was speeding or driving recklessly: Victim's dangerous driving may be the superseding cause
- Victim was also intoxicated: If the victim was DUI, their impairment may have caused the accident
- Pedestrian jaywalking or in roadway illegally: Victim's illegal conduct may be the cause
- Victim's vehicle mechanical failure: If the victim's car malfunctioned, that may be the true cause
Third-Party Conduct Caused the Death
- Another driver caused the collision through negligence or traffic violations
- Road hazards or defective road design caused the accident
- Government negligence (missing traffic signals, inadequate signage)
Unavoidable Accident
- Even a completely sober driver could not have avoided the collision under the circumstances
- Sudden emergency (animal in road, debris, another car swerving into your lane)
- Victim darted into traffic with no time to react
Your Vehicle Malfunction Caused Accident
- Brake failure that you couldn't have known about
- Tire blowout
- Steering failure
- Other mechanical defect
Strategy: I hire expert accident reconstructionists who analyze all physical evidence—skid marks, vehicle damage, road conditions, sight lines, weather—to determine the true cause of the accident. If I can establish that factors other than your intoxication caused the death, you cannot be convicted of vehicular manslaughter while intoxicated.
Defense Strategy 2: Challenge the DUI Element
Prosecutors must prove you were actually driving under the influence. All traditional DUI defenses apply in vehicular manslaughter cases:
- Illegal traffic stop: If police lacked reasonable suspicion, all evidence gets suppressed
- Breath test errors: Calibration issues, operator error, mouth alcohol, medical conditions affecting results
- Blood test problems: Chain of custody gaps, improper storage, contamination, fermentation, lab errors
- Rising BAC defense: Your BAC may have been under .08% during the accident but rose by testing time
- No impairment: Even if BAC was .08%+, evidence may show you were not actually impaired
- Post-accident drinking: You consumed alcohol after the accident to cope with trauma, not before
- Medical conditions: Diabetes, GERD, or other conditions created false high BAC reading
If I can create reasonable doubt about whether you were DUI, the charge must be reduced to vehicular manslaughter without intoxication (PC § 192(c)), which carries significantly lighter penalties and may be eligible for probation.
Defense Strategy 3: Challenge Gross Negligence
In PC 191.5(a) cases, I argue that even if you were negligent, your conduct did not constitute gross negligence:
- Speed was at or near the limit: Not grossly negligent if driving reasonably
- Single traffic violation: One mistake is ordinary negligence, not gross
- Low BAC: .08-.10% BAC shows minimal impairment, not reckless disregard
- No prior dangerous conduct: You weren't weaving, speeding excessively, or driving recklessly
- Momentary inattention: Brief lapse is ordinary negligence
- Unclear circumstances: If it's not clear exactly what you did wrong, gross negligence cannot be proven
Successfully arguing that only ordinary negligence existed reduces your maximum prison exposure from 10 years to 4 years—and makes probation theoretically possible, though still unlikely.
Defense Strategy 4: Challenge Watson Murder Charges
If prosecutors charge Watson murder, I attack the implied malice element:
Challenge the Prior DUI Conviction
- Prior conviction may be invalid due to lack of counsel or constitutional violations
- Prior may have been wet reckless, not DUI
- Prior occurred more than 10 years ago (weakens implied malice argument)
Challenge the Watson Advisement
- Court records may not show you actually received Watson advisement
- Advisement may have been inadequate or improperly given
- You may not have understood the advisement due to language barriers or mental condition
Negate Implied Malice
- Your BAC was low (.08-.10%), negating "conscious disregard for human life"
- You completed alcohol treatment after prior DUI, showing you took it seriously
- Significant time elapsed since prior DUI (5+ years)
- No dangerous driving conduct suggesting conscious disregard for life
- Evidence you didn't realize you were too impaired to drive
If I successfully defeat Watson murder charges, the case is reduced to vehicular manslaughter—reducing your sentence from 15-to-life to 4-10 years maximum. This is the difference between dying in prison and eventually regaining your freedom.
Defense Strategy 5: Negotiate Charge Reduction
Through aggressive negotiation with Nevada County prosecutors, I work to reduce charges to lesser offenses:
- Gross to ordinary: Reduce PC 191.5(a) to PC 191.5(b) (10 years max to 4 years max)
- Watson murder to manslaughter: Reduce murder charge to PC 191.5(a) or (b)
- Manslaughter to DUI causing injury: If death resulted from complications rather than direct trauma, argue for injury charge instead
- Remove intoxication element: Reduce to non-DUI vehicular manslaughter (PC 192(c))
Charge reductions depend on weaknesses in the evidence, strength of causation defenses, your criminal history, and mitigation evidence.
What to Do After Being Charged
CRITICAL: Take These Steps Immediately
Being charged with vehicular manslaughter while intoxicated is a life-or-death legal situation. You must act decisively:
- Invoke Right to Remain Silent: Do NOT give any statements to police about the accident, your drinking, where you were, or what happened. Police are building a homicide case—everything you say will be used to put you in prison. Say only: "I'm invoking my Fifth Amendment right to remain silent and I want my attorney."
- Hire an Attorney BEFORE Arraignment: Do not wait for a public defender. Vehicular manslaughter cases require immediate investigation, expert retention, and evidence preservation. The earlier I'm involved, the better your defense.
- Do Not Discuss the Case: Don't talk to anyone about the accident or case except your attorney—not family, not friends, not cellmates, not anyone. Conversations in jail are recorded. Witnesses will testify about what you said.
- Preserve Evidence: If you have dashcam footage, GPS data, phone records, or any other evidence, preserve it immediately and give it to your attorney.
- Do Not Contact Victim's Family: Any contact can be viewed as intimidation or obstruction of justice. Let your attorney handle all communications.
- Do Not Post on Social Media: Prosecutors monitor social media. Any posts will be used against you. Deactivate accounts if possible.
- Mental Health Support: These charges are traumatic. Seek counseling or therapy to process the emotional weight—this also demonstrates remorse and rehabilitation for sentencing purposes.
Why Experience Matters in Homicide Cases
Vehicular manslaughter while intoxicated is not a typical DUI case—it's a homicide prosecution. You need an attorney with serious felony trial experience who understands:
- Accident reconstruction: Working with expert witnesses to analyze the accident
- Causation evidence: How to challenge whether your conduct caused the death
- Forensic toxicology: Attacking blood and breath test results in homicide context
- Homicide jury trials: How to select juries and present defense in death cases
- Negotiating with prosecutors: How to negotiate charge reductions in homicide cases
- Mitigation at sentencing: Presenting evidence to minimize prison time when conviction is likely
- Local court experience: Understanding how Nevada County judges handle vehicular manslaughter cases
With 25+ years defending serious felony cases in Nevada County Superior Court, I have the experience necessary to handle these devastating charges.
Common Questions About Vehicular Manslaughter
What is the difference between gross vehicular manslaughter and vehicular manslaughter while intoxicated?
Gross vehicular manslaughter while intoxicated (PC 191.5(a)) requires proof that you drove under the influence with gross negligence, meaning reckless disregard for human life. It carries 4, 6, or 10 years in state prison. Regular vehicular manslaughter while intoxicated (PC 191.5(b)) requires only ordinary negligence and carries 16 months, 2, or 4 years in state prison. The distinction between gross and ordinary negligence is critical and can mean 6 additional years in prison.
What is Watson murder and when can I be charged with it?
Watson murder refers to second-degree murder charges (15 years to life) for DUI causing death when you have a prior DUI conviction and received a Watson advisement. This advisement, given during prior DUI sentencing, warns that driving drunk is extremely dangerous to human life and that killing someone while DUI in the future can result in murder charges. With this prior warning, prosecutors argue you had implied malice—conscious disregard for human life—making the death murder rather than manslaughter.
Can vehicular manslaughter charges be reduced or dismissed?
Yes, in certain cases. An experienced attorney can challenge whether you were actually driving under the influence, whether your conduct caused the death, whether gross negligence existed, and whether the death was truly your fault or resulted from the victim's actions, other drivers, or road conditions. If causation or gross negligence cannot be proven, charges may be reduced from gross vehicular manslaughter to regular vehicular manslaughter, or from manslaughter to DUI causing injury, or dismissed entirely.
Will I definitely go to prison for vehicular manslaughter while intoxicated?
Most likely, yes. Vehicular manslaughter while intoxicated is a serious felony, and judges rarely grant probation when someone died. However, in cases involving ordinary negligence (not gross), minimal impairment, significant victim fault, or extraordinary mitigation, probation with county jail time is theoretically possible though uncommon. The focus is often on reducing the charge severity and minimizing prison time rather than avoiding custody entirely.
What should I do immediately after being arrested for DUI causing death?
First, invoke your right to remain silent immediately and request an attorney. Do not give any statements about the accident, your drinking, or what happened—police are building a homicide case against you. Second, hire an experienced criminal defense attorney immediately, before your arraignment. Third, do not discuss the case with anyone except your attorney. Fourth, preserve any evidence like dashcam footage, phone records, or witness information. Fifth, do not post anything on social media. These cases require immediate, aggressive legal representation.
How is vehicular manslaughter different from DUI causing injury?
The critical difference is whether someone died. DUI causing injury (VC 23153) applies when victims are injured but survive. Vehicular manslaughter while intoxicated (PC 191.5) applies when someone dies as a result of the DUI accident. The penalties are dramatically different: DUI causing injury carries 16 months to 3 years prison (before enhancements), while vehicular manslaughter carries 16 months to 10 years prison depending on the level of negligence. Vehicular manslaughter is treated as a homicide offense.
Can the victim's family sue me in civil court?
Yes, absolutely. In addition to criminal prosecution, the victim's family will almost certainly file a wrongful death civil lawsuit against you. This is separate from the criminal case and can result in millions of dollars in civil liability. You'll need both a criminal defense attorney (for the criminal charges) and a civil attorney (for the lawsuit). Any statements you make in the criminal case can be used against you in the civil case, which is why invoking your right to remain silent is critical.
What if I wasn't the only person at fault in the accident?
Comparative fault can be a powerful defense. If the victim, another driver, or other factors substantially contributed to causing the accident, this can reduce or eliminate your criminal liability. Even if you were somewhat at fault, if someone else's conduct was a more significant cause, you may not be guilty of vehicular manslaughter. An experienced attorney will conduct a thorough investigation to identify all contributing factors and alternative causes.
