California law allows traffic violators to attend traffic school once every 18 months to have a traffic ticket dismissed. Once the ticket is dismissed it will not show up on any DMV record and will not cause insurance to be raised. What many people do not realize about traffic school is that it is only allowed for certain violations. For example, it is not allowed for DUI, reckless driving and driving on a suspended license. The classes are also not allowed for speeding tickets over 20 miles per hour over the speed limit. However, in Kern County where we practice we can get the 20 mph rule waived in many cases if the attorney convinces the judge that the interests of justice would be advanced. Traffic school is also not permitted if the driver has a commercial license, even if the offender was not in a commercial vehicle at the time of the ticket. Once again, these rules are general and can often be waived if a lawyer is retained in Kern County California.
