Driving Under the Influence (DUI).

The term “under the influence” refers to the fact that drugs and alcohol affect, or “influence”, a person’s behavior. Alcohol is a depressant, which can slow down a person’s motor skills, thus affecting his or her driving ability. Drugs can be either a depressant or a stimulant. In the U.S. driving while under the influence of drugs or alcohol is illegal.

Some states use other acronyms:

OWI in Indiana and Iowa: Operating While Intoxicated;

OUI in Massachusetts and Rhode Island: Operating Under the Influence;

OVI in Ohio: Operating a Vehicle While Intoxicated;

DUII in Oregon: Driving Under the Influence of Intoxicants.
