Just a little more. CSP also has a CSI unit in Sacramento and individual CSi officers in other offices. CSP had 21 offices from Redding to San Diego. The photo of the 1988 Chevy is technically the 3rd version. The first two were CSP shoulder patches on the front doors. One patch style from the early 50's to 1973. Then the patch was redesigned. That lasted until 1984 when the pictured markings were used. Around 1989-90 a new chief was appointed and started new patrol vehicle markings.

The CSP provided the full range of police services to state agencies and property. They were not limited to buildings and grounds. A lot of states have a state police/highway patrol and a capitol police. But I think California was the only one with two full peace officer power/authority agencies.

Before the merger of the two agencies, the California Highway Patrol was responsible for the enforcement of the vehicle code. While this may sound rather simplistic in nature, this included but not limited to commercial vehicle inspection, drug intradiction, and one of the extensive auto & cagro theft investigative units. Because may traffic stops lead to more then just a ticket, the CHP leads many California law enforcement agencies in the most felony arrests.
The California State Police (When In Existence) were responsible for protecting state buildings & grounds, employees & visiters to state property, & protection of constitutional officers like the Governor, Lt. Governor, State Senators, including visiting dignitaries upon request. They also have Threat Assestment Unit which investigated threats made against government officals, & was the agency to report any threats made against a government offical. Their Protection Of Public Officals dignitary protection course was considered a model for alot of LE agencies which train their staff in the protection of government officals. Major state sites requiring protection included the Capitol, Governor's Mansion, California Aquaduct (State Water Project), Transbay Transit Terminal, state archives, library, State Appellate & Supreme Court, National Guard Armories, State owned bridges,Department Of Motor Vehicles, Employment Developement Department, and ironcially CHP Offices! They conducted criminal investigations, and assist various State agencies like the Franchise Tax Board & Board Of Equalization perform asset foreiture seixure. The CSP had amoung it's arsenal an EOD unit, dive team, mounted equestrian unit, bike detail, four wheel drive Broncos & Ram SUV's. Now only wish they could get shots of these! Most of the CSP's duties were absorbed inot the CHP upon the merge of July 1995. Before the merge, the CSP ironically was 108 years old! Making them at the time the state's oldest law enforcement agency.

You should do some research because there are several states that have both.

As it says above, the California State Police no longer exists. It was pretty much sucked in by the CHP and all of the responsibilities that the state police had were given to the CHP. You can go to the CHP website to find out more about this merging.

What was the difference between the California State Police and the California Highway Patrol? I have never heard of a state having both a state police and highway patrol.

Sorry! Meant airplane!

Nice shot of a now defunct agency. Wish you had more! How about their specialized units like EOD, SWAT, Aiplane, Horse Carriers, K-9, station wagons, etc.
