What it is
The CHP was established "to provide uniform traffic law enforcement throughout the state", and its remit runs statewide. That combination — state level, narrow subject matter — is common in the United States and is routinely misread: a primary state agency is not a state equivalent of a national police force, and does not supersede the municipal and county agencies operating in the same places.
What it covers
The State of California, for the purposes of its remit.

SCOPE: the California Highway Patrol only. The agency’s own page, read directly. Supports the official name "California Highway Patrol (CHP)", that it was established in 1929 "to provide uniform traffic law enforcement throughout the state", that its remit runs statewide, and its stated mission "to provide the highest level of Safety, Service, and Security". The page did NOT name the state department it sits within, and none is asserted from it. Establishes nothing about municipal or county agencies in California.

Reference date June 2018. Supports that 17,541 general-purpose state and local law-enforcement agencies performed law-enforcement functions in the United States, of which about 67% were local (municipal) police departments, 17% sheriffs' offices, and 15% primary state, tribal, special-jurisdiction agencies, constables and marshals, together employing about 1,214,000 full-time personnel. Supports the FRAGMENTATION of US policing across thousands of separately governed agencies. Does NOT support any per-state figure or any claim about a specific agency.
