In November, 1988, the electorate in California approved Proposition 103 to prevent the massive increases in premiums that were affecting all consumers looking for insurance. After major litigation to decide whether the Proposition was constitutional, it was finally implemented in May 1989 and rapidly revolutionized the rates of insurance across the state which fell by an average of 45% between 1989 and 2001. It is estimated that up to 2006, Californian drivers alone saved $62 billion on their auto insurance rates.
