From a website that provides "Info & Advice about California Red Light Camera Tickets":
FAQ # 15:
Why is the fine so high in California ? Are there exceptions?Answer: When defendants raise that question in court, the judges explain that the State legislature set the fine so high
(current fine is approx. $470, not including the approx. $100 cost of attending traffic school) in order to strongly deter drivers from running red lights. They also usually quote figures, provided by the local police, which say that accidents here are down 10 - 40% as the result of the cameras. But on the east coast, where the fines are just $50 to $75 (and the tickets do not carry a "point"), the police there have been publishing similar accident reduction figures. Evidently, at least on the east coast, a much smaller penalty has been equally effective in getting drivers to behave.

The California legislature is continuing to increase the fine. A new $20 surcharge went into effect on June 10, 2010 (enacted by Executive Session Bill ACX 8-3), and as of July 2010 there is a proposed new $40 surcharge which if enacted will go into effect on Jan. 1, 2011....http://www.highwayrobbery.net/redlightcamslinksref.htm#FAQ
