What offenses count as a third-degree felony for DWI?

The classification of a third-degree felony for DWI typically includes specific and serious offenses. The correct answer identifies that both the third offense and vehicular homicide are considered third-degree felonies.

A third DWI offense usually escalates from previous infractions, signifying repeat offenses that can lead to harsher penalties due to a pattern of unsafe driving behavior. This illustrates a continued disregard for safety and the law. Similarly, vehicular homicide represents a tragic consequence of driving while impaired, making it imperative for legal systems to enforce strict sanctions due to the severe nature of taking another person's life while under the influence.

In contrast, the other options would not satisfy the conditions for third-degree felonies. First and second offenses are typically classified under lesser degrees of felonies or misdemeanors, depending on the jurisdiction. Moreover, defining all DWI offenses or only vehicular homicide as third-degree felonies would neglect the legal distinctions made based on the number of offenses and the specific circumstances involved, such as causing death or serious injury.
