For clarity, the vehicular manslaughter laws referenced by parent commenter are specifically for when [criminal] negligence is involved (and yes parent commenter’s use of “accident” does imply absence of negligence, so I appreciate your calling them out, they don’t seem to understand the law):

> In cases of criminal negligence, the defendant is commonly charged with unintentional vehicular manslaughter.
