In California a new law took effect on January 1, 2007 regarding a CA driving record and how long a DUI offense is listed on it. This new legislation extends the reporting period for DUI offenses from 7 to 10 years for all public requestors, including insurance companies.
Also based on the new California laws, drivers with a DUI violation occurring within the past 10 years are not entitled to receive a good driver discount.
The CA Department of Motor Vehicles states that even if a DUI was previously taken off of your record (due to the previous time period of 7 years) that it will now appear back on your driving record and will remain there until 10 years from the violation date. So for instance if you received a DUI in June 1999 and it was previously taken off your record after 7 years it will now show back up on your driving record and remain there until June 2009.

All other convictions of traffic violations will be reported for 3 years from violation date. Again this is violation date and not the date of the conviction.
The exceptions are violations occurring in a commercial vehicle, which are the basis for an action under Vehicle Code (VC) 15300a, 15300b, 15302, 15304, and 15306, which will be reported for 55 years from the conviction date. |
