Good driver discount

A premium reduction for drivers with no recent at-fault accidents or significant violations, mandated at 20% or more in California.

Also called: accident-free discount, claim-free discount, clean record discount

A good driver discount rewards a clean driving record. Insurers look back over a set period, often three to five years, at your motor vehicle report and claims history, and if you have had no at-fault accidents and no significant violations, you qualify for a lower rate. Names and rules vary; some insurers call it an accident-free, claim-free or safe driver discount, and some build it into their base pricing instead of listing it.

California is the clearest example of a legal mandate. Under proposition 103, insurers must give qualifying good drivers a discount of at least 20%. To qualify, a driver must have been licensed for the previous three years, have no more than one violation point in that time, not have been principally at fault in an accident causing injury or death, and have no DUI conviction within the past 10 years.

Elsewhere the discount is voluntary and the amount differs by company. It is separate from telematics programs, which measure how you drive now rather than looking at your record. One at-fault accident or moving violation can cost you the discount for years, which is part of why a ticket or claim raises premiums by more than the surcharge alone. Ask insurers how far back they look and what counts against you.
