In Massachusetts, a motorist can be convicted of "homicide by motor vehicle" (also called "vehicular homicide") for causing the death of another person while driving:
Negligence. A person acts with negligence by doing something that a reasonably careful person would not.
Under the influence. For purposes of Massachusetts's vehicular homicide law, "under the influence" means the motorist:
Causation. A driver can be convicted of homicide by motor vehicle only if there's proof that the driver was a legal cause of the death. It's not enough to merely show the defendant drove negligently or while under the influence and someone died—there needs to be a direct link between the defendant's driving and the death.
The consequences of a homicide-by-motor-vehicle conviction depend on the circumstances. However, the possible penalties are:
For a first vehicular homicide conviction, there's a 15-year license revocation. And motorists who are convicted of vehicular homicide for a second time face lifetime revocation.
HOW MUCH TIME WOULD YOU ACTUALLY SPEND IN JAIL?
Sentencing law is complex. For example, a statute might list a "minimum" jail sentence that's longer than the actual amount of time (if any) a defendant will have to spend behind bars. All kinds of factors can affect actual punishment, including credits for good in-custody behavior, "suspended" sentences, and jail-alternative work programs.
