States simply use different abbreviations and terms to mean the same thing. DWI is used as shorthand within multiple states to stand for “driving while intoxicated.” For example, in Colorado, the courts use DUI to mean “driving under the influence” or DWAI for “driving while ability impaired.” In Colorado, law enforcement has the right to request consent to take a blood, breath, saliva, or urine test when they suspect that you may be intoxicated.
