The purpose of the current study is to provide empirical data on cases of police driving under the influence (DUI) of alcohol and/or drugs. The study identifies events that may have influenced the decision to arrest, including associated traffic accidents, fatalities, officer resistance, the refusal of field sobriety tests, and the refusal of blood alcohol content tests. The study is a quantitative content analysis of news articles identified through the Google News search engine using 48 automated Google Alerts queries. Data are analyzed on 782 DUI arrest cases of officers employed by 511 nonfederal law enforcement agencies throughout the United States. The study is the only study known to describe police officer DUI arrests as they occur within police agencies across the United States.
