The University of California Police Officers generally provide for the peace, safety, and security of persons and facilities on the university campus and those properties owned, controlled, or occupied by the University of California. It is the function of the patrol division to provide twenty-four hour uniformed patrol coverage to all areas of the university. Officers provide preventative patrols on foot, bicycle, and motor vehicles; receive, process, and investigate complaints by citizens; respond to emergencies such as crimes, accidents, injuries, illness, and fires; protect persons and property through crime prevention; arrest offenders; appear in court; provide traffic control and enforcement; attend community meetings; perform miscellaneous services related to public health and safety; safeguard the custody and disposal of evidence and lost and found property.

The Field Operations Division is comprised of the traditional line functions (patrol services and field training unit) of the police department and is managed by a Lieutenant. As such, most sworn personnel are assigned to this area of the department. The Administration Division consists of Investigations, Crime Prevention, Community Service Officers, Communications and Special Units.
The primary function of personnel assigned to Patrol is to provide a uniformed response to calls for service and to act as a visible deterrent to crime. As the most visible part of the department, our officers are called upon to protect the community with customary policing methods and to provide the foundation of resources for other outreach programs to the community. The Bicycle Patrol Units provide a highly visible patrol presence, allowing for a rapid response to call-for-service, and a positive interaction between the Community and the Department.
The officers of the UC Irvine Police Department are deployed equally among two patrol shifts. They provide the base for several specialized communities within UCI. We have officers assigned to primary patrol responsibilities in the following area: University housing, University apartments, and the Fraternity and Sorority apartments.
