The penalties for killing someone while driving drunk are quite severe. Typically, a motorist who's convicted of a DUI-related (or BUI-related (boating under the influence)) killing is looking at felony charges that carry jail or prison time, fines, and license suspension or revocation.
Generally, a motorist who causes the death of another person while driving under the influence of drugs or alcohol faces felony charges. However, state laws differ on how DUI-related killings are charged. In many cases, the prosecutor will have several options.
Some states have DUI statutes that specify more severe penalties for DUI offenses involving deaths. In Michigan, for instance, a standard first OWI (operating while intoxicated) is a misdemeanor and carries up to 93 days in jail and a maximum of $500 in fines. But a Michigan OWI offender who causes the death of another person is guilty of a felony and faces up to 15 years in prison and $2,500 to $10,000 in fines.
Lots of states have laws that are specific to driving-related unlawful killings. For example, in Florida, a motorist can be convicted of "vehicular homicide" for causing the death of another while driving in a "reckless manner." The vehicular homicide statute applies to all killings that result from driving in a reckless manner—not just those that involve driver intoxication. Generally, a Florida vehicular homicide conviction is a second-degree felony and carries up to 15 years in prison and a maximum of $10,000 in fines. Florida law also provides a DUI enhancement that makes a DUI-related killing a second- or first-degree felony. So, for DUI-related killings, Florida prosecutors can choose whether to charge vehicular homicide, the DUI-death enhancement, or both.
California, on the other hand, doesn't have a DUI-death enhancement (unless multiple victims were killed or injured) but does have vehicular manslaughter laws specific to DUI-related offenses. A California DUI offender who—with negligence or gross negligence—violates a traffic law or does a lawful act which might produce death in an unlawful manner and kills another person can be charged with "negligent vehicular manslaughter while intoxicated" or "gross vehicular manslaughter while intoxicated." Depending on the circumstances, a convicted motorist faces four years to life in prison.
Even if a state has laws that specifically apply to driving- or DUI-related killings, someone who kills another while driving under the influence can typically be convicted of a more general crime—like involuntary manslaughter or second-degree murder.
