Proposition 33 would change the law so insurance companies could set prices for automobile insurance based on whether you had insurance with any other company before. Drivers who don’t have a history of continuous insurance would pay more. Special exceptions would be made for drivers who drop their insurance in order to serve in the military or because of loss of employment. The measure also has a grace period of 90 days, so drivers who drop their insurance but purchase new insurance within 90 days would still be considered as continuously covered.
