Manslaughter is the unlawful killing of a human being without malice. It is of three kinds:
(a) Voluntary -- Upon a sudden quarrel or heat of passion.
(b) Involuntary-- In the commission of an unlawful act, not amounting to felony; or in the commission of a lawful act which might produce death, in an unlawful manner, or without due caution and circumspection. This subdivision shall not apply to acts committed in the driving of a vehicle.
(c) Vehicular --
(1) Except as provided in subdivision (a) of Section 191.5, driving a vehicle in the commission of an unlawful act, not amounting to felony, and with gross negligence; or driving a vehicle n the commission of a lawful act which might produce death, in an unlawful manner, and with gross negligence.
(2) Driving a vehicle in connection with a violation of paragraph
(3) of subdivision (a) of Section 550, where the vehicular collision or vehicular accident was knowingly caused for financial gain and proximately resulted in the death of any person. This provision shall not be construed to prevent prosecution of a defendant for the crime of murder.
This section shall not be construed as making any homicide in the driving of a vehicle punishable that is not a proximate result of the commission of a lawful act which might produce death, in an unlawful manner.
"Gross Negligence," as used in this section, shall not be construed as prohibiting or precluding a charge of murder under Section 188 upon facts exhibiting wantonness and a conscious disregard for life to support a finding of implied malice, or upon facts showing malice, consistent with the holding of the California Supreme Court in the case of People v. Watson, 30 Cal.3d 290
