Highway Patrol duties
The agency has specific jurisdiction over all California state routes, U.S. Highways, Interstate highways freeways in the state and all public roads in unincorporated parts of a county. Local police or the local sheriff's department having a contract with an incorporated city have responsibility to investigate and enforce traffic laws in incorporated cities. However, the CHP can still enforce traffic laws on any public road anywhere in the state regardless if it is in an incorporated or unincorporated city.
Its officers enforce the California Vehicle Code (including laws against speeding), pursue fugitives spotted on the highways, and attend to all significant obstructions and accidents within their jurisdiction. They patrol in various vehicles including Ford Crown Victoria Police Interceptors, Chevrolet Camaros, BMW R1150RT-P motorcycles, Cessna 206 airplanes, and helicopters which include Bell OH-58As, Bell 206L-IVs and Eurocopter AS-350B-3s. The CHP has a fleet of 73 Chevrolet Camaros, which are used for commercial vehicle patrols.
CHP officers are responsible for investigating and disposing of car accidents, debris, dead animals and other impediments to the free flow of traffic. They are often the first government officials at the scene of an accident (or obstruction), and in turn summon paramedics, tow truck drivers or Caltrans personnel. The CHP files traffic collision reports for state highways and within unincorporated areas.
