In California the CA Department of Motor Vehicles keeps a public record of all your traffic convictions and accidents. The length of time that the violation remains on your MVR depends on the severity of the offense. Most violations (illegal turn, not making a complete stop, driving over the speed limit, etc.) and/or accidents will stay on your driver record for 36 months (3 years). More serious offenses, such as hit-and-run or a DUI, will stay on your record for up to 10 years.
Ticket convictions stemming from the CA cell phone laws are reportable offenses, so they will go on your California driving record however, the CA DMV will not assign a violation point to your MVR. Since it is a minor offense it will remain on your driving record for 3 years.

There are state and county fees typically as well as court costs to process the ticket and thus a ticket can easily be double or in as in this case 4 times the base fine amount. |
