In California, the consequences of vehicular assault are nothing short of life-altering. A single moment of gross negligence, a reckless turn behind the wheel, or an act that endangers human life can quickly shift from a car accident to a criminal charge.
Many ask, “What is the max sentence for vehicular assault in CA, and what defines vehicular manslaughter?” The answer depends on a web of factors, such as intent, the harm caused, and the exact circumstances of the accident.

What Does California Penal Code Section 191.5(a) Say About Involuntary Manslaughter?
Under California Penal Code sections, particularly Penal Code 192(c) and Penal Code 191.5(a), offenses like gross vehicular manslaughter, vehicular manslaughter while intoxicated, and even assault with a deadly weapon, when that weapon is a motor vehicle, can carry severe legal outcomes.
These include sentences ranging from up to one year in county jail for misdemeanor charges to several years in state prison for felony offenses involving great bodily injury or death.
Can Gross Vehicular Manslaughter Be Counted as Attempted Murder?
Gross vehicular manslaughter involves a driver who causes another person’s death through gross negligence, often while under the influence of alcohol or drugs.
The motorist does not intend to kill but acts in a way that a reasonable person would recognize as extremely dangerous. This offense is charged under California Penal Code Section 191.5(a) and carries a felony conviction, often resulting in state prison sentences.
By contrast, attempted murder requires proof that the defendant acted with the deliberate intent to kill, which is something rare in most traffic-related cases.
Prosecutors must show not just reckless driving but a clear desire or plan to produce great bodily harm or unlawful killing.
Unless there is evidence of road rage, premeditation, or a deliberate act such as using a car as a deadly weapon, it’s uncommon for a vehicular manslaughter charge to be elevated to attempted murder under California law.
That said, prosecutors can and do push for more serious charges in extreme cases if the automobilist has a history of DUI convictions, was driving at dangerous speeds, or showed clear disregard for human life.
What If the Deadly Weapon Was Used as Self-defense Against Great Bodily Injury?
In cases where a driver uses a car to escape a violent threat or serious injury, such as an armed assailant approaching the window or someone attempting to pull them from the vehicle, California’s self-defense laws may apply.
The burden falls on the defense team to show that the driver truly believed they were in immediate danger. As a result, they must show that using the car as a defensive measure was proportional and necessary under the circumstances.
The Difference Between Ordinary and Gross Negligence
Ordinary negligence refers to a momentary lapse in judgment, such as a failure to use reasonable care that a typical person would exercise under similar circumstances.
Examples include failing to signal a turn or slightly speeding. While still dangerous, such actions are not necessarily criminal unless they result in a fatal accident or substantial physical injury.
Gross negligence involves behavior that goes beyond carelessness. Grossly negligent conduct shows a reckless disregard for others.
It involves a driver acting in a way that any reasonable person would find dangerous and irresponsible. Running red lights at high speed, racing on public roads, or driving under the influence may all qualify as gross negligence if they lead to death or injury.
California's vehicular manslaughter law defines traffic violations differently based on the type of negligence involved.
Charges rooted in ordinary negligence may result in misdemeanor consequences, whereas the defendant may face felony charges and the possibility of state prison time for gross negligence.
Common Criminal Defenses Used During Trial
A powerful angle is challenging whether an unlawful act took place. If the incident was caused during a lawful act, such as stopping quickly to avoid another car accident, the legal grounds for a felony can weaken.
In fact, some cases rely heavily on proving that no unlawful killing took place, especially when the accident caused only a physical injury rather than death.
One of the most common and effective defenses is built on reasonable doubt. Prosecution carries the burden of proof.
If the defense team can highlight inconsistencies, lack of clear evidence, or missing details, jurors may hesitate to convict in complex vehicular manslaughter cases.
Defendants facing a felony offense may also invoke California’s "Three Strikes" law, particularly if prior convictions are involved.
A skilled legal team will seek to prevent further strikes or extended sentences, which can lead to up to six years or more in prison. They can help answer questions like What is the penalty for vehicular assault in CA?
Are Vehicular Manslaughter Lawsuits Judged by Jury Instructions?
In such trials, jurors are not expected to be legal experts. Instead, they are provided with precise jury instructions, which outline the law and the standards that must be met to find someone guilty.
Ultimately, the jury must decide beyond a reasonable doubt whether the driver’s actions were so careless that they crossed the line into criminal behavior.

Seeking Legal Representation from a Reputable Law Firm
The consequences of a felony conviction can be life-altering, with the possibility of state prison, driver’s license suspension, and a permanent record in the criminal justice system. In these high-stakes cases, a reputable law firm can make all the difference.
