This 21-year-old got 12 years in prison for DUI. Here's what made it so serious. Because of his intoxication, he had an accident where he caused serious bodily injury to another person. That makes it in Tennessee what we call a vehicular. And that's why it's punished on a different level than a DUI. If you cause the serious bodily injury of another person, even if it's your first offense ever, it becomes a defelony, which is punishable by up to 12 years in prison. It's a very serious crime.
