A more thorough explanation:

DUI

DUI stands for driving under the influence, which means driving after drinking alcohol or taking drugs that affect your ability to drive safely. It is also called driving while intoxicated (DWI). It is a criminal offense and can result in fines, license suspension, and even jail time.

1. John was arrested for DUI after he was caught driving erratically and failed a breathalyzer test.

2. Sarah was charged with DUI after she was found asleep in her car with the engine running and a bottle of vodka in the passenger seat.

These examples illustrate how DUI involves driving while under the influence of alcohol or drugs, which impairs a person's ability to drive safely. In both cases, the individuals were arrested and charged with a criminal offense because they were operating a vehicle while impaired.
