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.

In Alaska, vehicular manslaughter is referred to as 'negligent homicide' under Alaska Statute 11.41.120. It is defined as the unintentional killing of another person as a result of criminal negligence by the operator of a motor vehicle. Criminal negligence in this context means that the person fails to perceive a substantial and unjustifiable risk that a certain result will occur or that a circumstance exists. This offense is considered a class B felony in Alaska, which can result in significant penalties, including imprisonment. The exact sentence can vary based on the circumstances of the case, the defendant's criminal history, and other factors. If the operator was under the influence of alcohol or drugs, additional charges related to DUI (driving under the influence) may also apply under Alaska Statute 28.35.030. Penalties for vehicular manslaughter can include substantial fines, lengthy prison sentences, and the suspension or revocation of driving privileges.
