In California, and in 32 other states, seniors can receive up to 15% discount on their insurance premium in exchange for providing proof of completion of a Senior Driving Course. Even better news, many of these courses will cost you nothing (although the certificate may cost you a minimal fee). In our town the local community college offers these courses at least twice a year for free. You can also find the courses, for a fee, on the internet. If you are looking at internet providers make sure that they are accepted by AAA.
If you noticed that your car insurance premium increased when you hit 55, this is one way to bring it back down. - Jane
