CALCRIM No. 580 defines criminal negligence as follows: "Criminal negligence involves more than ordinary carelessness, inattention, or mistake in judgment. a person acts with criminal negligence when: He or she acts in a reckless way that creates a high risk of death or great bodily injury; AND A reasonable person would have known that acting in that way would create such a risk. In other words, a person acts with criminal negligence when the way he or she acts is so different from the way an ordinarily careful person would act in the same situation that his or her act amounts to disregard for human life or indifference to the consequences of that act."
