Different states call drunk driving by different names. Some states use the term “Driving Under the Influence” (DUI), and other states use the term “Driving While Impaired” or “Driving While Intoxicated” (DWI). Still other states have other acronyms, such as “Operating Under the Influence” (OUI).
It doesn’t matter what the offense is called. Each state has somewhat different laws about how to treat what is commonly called “drunk driving,” although in every state a blood alcohol concentration of .08 (BAC) is enough to convict the defendant of a DUI, DWI, or OUI.
In North Carolina, the offense is called Driving While Impaired (DWI).
