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 Vermont, vehicular manslaughter is addressed under the state's laws concerning motor vehicle operation resulting in death. Specifically, Vermont Statutes Title 23 (Motor Vehicles), Section 1128, defines 'Negligent Operation' and Section 1091 covers 'Grossly Negligent Operation.' When a death occurs due to negligent operation of a vehicle, it can be prosecuted under these statutes. If the operator is under the influence of alcohol or drugs, the offense may be elevated to a more serious charge under Vermont's DUI statutes, which include penalties for DUI resulting in death. The exact classification of the offense (misdemeanor or felony) and the associated penalties, such as imprisonment, fines, or license suspension, depend on the circumstances of the case and the operator's prior record. It is important to note that Vermont law considers the seriousness of the offense and the level of negligence when determining the appropriate charge and punishment.
