Driving while intoxicated (DWI) and driving under the influence (DUI) in some states are separate crimes. Generally, DWI is a more serious crime that involves a person who is under a lot of poisoning. DUI usually refers to a person who is driving with a moderate amount of intoxication.
Another approach is separating these crimes by a procedure used to convict someone. For example, sometimes the term DWI is used to refer to a statutory test "per se".
