Vehicular manslaughter is a criminal offense defined as the unintentional killing (homicide) of another person as a result of criminal negligence or recklessness while operating a motor vehicle—often while the operator is intoxicated by alcohol or drugs, engaged in a high risk activity such as street racing, or committing a misdemeanor or infraction offense (speeding) with ordinary negligence.

Vehicular manslaughter is usually a felony offense and often includes significant jail or prison time as potential punishment. Vehicular manslaughter laws vary from state to state and are generally located in a state’s statutes—often in the penal or criminal code.
