What Is Vehicular Manslaughter While Intoxicated in California?

Under California Penal Code Section 191.5, vehicular manslaughter while intoxicated is a separate and more serious charge than regular vehicular manslaughter — because it involves driving under the influence of alcohol or drugs at the time of the fatal accident.

There are two levels of this charge in California:

Gross Vehicular Manslaughter While Intoxicated — PC § 191.5(a) This is the more serious version. It means driving under the influence AND acting with gross negligence — meaning your driving was so reckless that it showed a complete disregard for human life.

• Classification: Felony
• Sentence: 4, 6, or 10 years in state prison
• Strike: Yes — counts as a serious or violent felony
• DMV: Mandatory license revocation

Vehicular Manslaughter While Intoxicated — PC § 191.5(b) The less serious version where the driving was negligent but not grossly so.

• Classification: Wobbler — charged as misdemeanor or felony
• Sentence: Up to 1 year (misdemeanor) or 16 months, 2, or 4 years (felony)
• Strike: No for misdemeanor, potentially yes for felony

The Watson Murder Rule — When DUI Manslaughter Becomes Murder

This is the most critical thing to understand if you have prior DUI convictions in California. Under the Watson Murder Doctrine (People v. Watson, 1981) — if you have a prior DUI conviction and you cause a fatal accident while driving under the influence — San Diego prosecutors can charge you with second-degree murder under California Penal Code Section 187.

This means:

• 15 years to life in state prison — not manslaughter
• A serious felony strike on your record
• No possibility of parole for at least 15 years

When you were convicted of a prior DUI in California you were given a Watson admonishment — a warning that future DUI causing death could be charged as murder. San Diego prosecutors use this admonishment as evidence of implied malice.

Jason Ronis Law defends both gross vehicular manslaughter and Watson murder allegations — and challenges the implied malice element aggressively.

How Jason Ronis Law Defends Vehicular Manslaughter While Intoxicated

Challenging “Gross Negligence” The difference between gross vehicular manslaughter (up to 10 years) and ordinary vehicular manslaughter while intoxicated (up to 4 years) hinges on whether your driving rose to the level of “gross negligence.” Jason Ronis Law challenges this element vigorously — presenting evidence that your driving, while negligent, did not show a complete disregard for human life.

Disputing Causation For a conviction the prosecution must prove your intoxication caused the fatal accident — not the actions of another driver, a road defect, a mechanical failure, or poor weather conditions. Jason Ronis Law retains accident reconstruction experts to challenge the prosecution’s causation theory.

Challenging the Blood Alcohol Evidence Breathalyzer results and blood tests must meet strict chain of custody and calibration requirements. Jason Ronis Law challenges BAC evidence — looking for testing errors, improper handling, timing issues, and calibration failures.

Fighting the Watson Murder Allegation If the DA attempts to charge second-degree murder under the Watson doctrine, Jason Ronis Law challenges the implied malice element — arguing that you lacked the subjective awareness that your conduct was dangerous to human life at the time of the accident.

Accident Reconstruction Jason Ronis Law works with top forensic accident reconstruction experts to challenge the prosecution’s accident narrative — including speed analysis, point of impact, sightlines, road conditions, and other driver behavior.
