California police officers' authority is derived from the California Penal Code (PC) beginning with Section 830. PC 830.1 includes the California Department of Justice (CA DOJ) along with local and county agencies. PC 830.2 includes the California Highway Patrol (CHP) and nine other state agencies. PC 830.3 includes 21 state agencies with law enforcement divisions.[2]
The California Commission on Peace Officer Standards and Training maintains a list of state law enforcement agencies on its website.[3]
