Driving Under the Influence (DUI) is a serious criminal offense that occurs when a person operates a vehicle while impaired by alcohol, drugs, or other intoxicating substances. DUI laws are strictly enforced to prevent accidents, injuries, and fatalities caused by impaired driving. Legal limits for blood alcohol concentration (BAC) vary by jurisdiction, but exceeding the set limit can lead to severe consequences, including fines, license suspension, mandatory alcohol education programs, and even jail time. Repeat offenders or cases involving accidents, injuries, or fatalities face even harsher penalties. Law enforcement agencies use sobriety checkpoints, breathalyzer tests, and field sobriety assessments to detect impaired drivers and enhance road safety.
