It is unlikely that a person who has no prior offenses for improperly handling a vehicle will be charged with vehicular homicide.
Prior offenses which may result in charges being upgraded from vehicular manslaughter to vehicular homicide include prior convictions for driving under the influence, or if a person was intoxicated at the time of the crime under investigation.

Vehicular homicide is a special circumstance of negligent homicide. It is not governed by a specific portion of the Model Penal Code, which outlines most criminal laws in effect in the United States.
