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 Utah, vehicular manslaughter is referred to as 'Automobile Homicide' and is codified under Utah Code § 76-5-207. This offense is considered a second-degree felony if the driver was found to be operating the vehicle in a criminally negligent manner and under the influence of alcohol, drugs, or a combination of both, resulting in the death of another person. The statute also covers situations where the driver has a blood alcohol content level of .08 grams or higher at the time of the accident. If convicted, the penalties can be severe, including potential imprisonment, fines, and a suspension of the driver's license. The specific circumstances of the incident, such as prior convictions or the level of negligence involved, can influence the severity of the punishment. It is important for individuals facing such charges to consult with an attorney who is experienced in criminal defense and understands the complexities of Utah's automobile homicide laws.
