What is the most serious charge for a driver aged 21 or older who causes death while driving under the influence?

Driving under the influence and causing death is a grave offense, and in Texas, the most serious charge for a driver aged 21 or older in such a situation is Intoxication Manslaughter. This charge reflects the severe consequences of operating a vehicle while intoxicated and resulting in the death of another person. Intoxication Manslaughter emphasizes the reckless disregard for human life that comes with choosing to drive while impaired. The law categorizes this offense as a second-degree felony, which carries substantial penalties, including significant prison time and fines.

Intoxication Assault, while also a serious charge, pertains to causing serious bodily injury to another person while driving under the influence, rather than resulting in death. Driving While Intoxicated is a lesser charge focused solely on the act of driving with an elevated blood alcohol concentration without the added element of causing death. Vehicular Homicide may seem comparable, but in Texas, it typically covers a broader range of fatal accidents that do not necessarily involve intoxication.

Thus, Intoxication Manslaughter represents the most severe repercussions for an impaired driver involved in a fatal incident, distinguishing it as the correct selection in this context.
