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 South Carolina, vehicular manslaughter is referred to as 'reckless vehicular homicide' and is addressed under South Carolina Code of Laws Section 56-5-2910. This statute defines the offense as the killing of a person while driving a vehicle in a reckless manner that demonstrates a willful or wanton disregard for the safety of persons or property. This is considered a felony in South Carolina. Conviction for reckless vehicular homicide can result in imprisonment for up to 10 years, as per Section 56-5-2940. Additionally, if alcohol or drugs are involved, the offender may face charges under South Carolina's felony DUI laws, which include harsher penalties if the impaired driving results in death. These penalties can include fines and a mandatory minimum prison sentence, with the possibility of a longer sentence depending on the circumstances of the case.
