n. the crime of causing the death of a human being due to illegal driving of an automobile, including gross negligence, drunk driving, reckless driving, or speeding. Vehicular manslaughter can be charged as a misdemeanor (minor crime with a maximum punishment of a year in county jail or only a fine) or a felony (punishable by a term in state prison) depending on the circumstances. Gross negligence or driving a few miles over the speed limit might be charged as a misdemeanor, but drunk driving resulting in a fatality is most likely treated as a felony. Death of a passenger, including a loved one or friend, can be vehicular manslaughter if due to illegal driving. (See: manslaughter, reckless driving, gross negligence)
