f the court sends a courtesy notice, it will say if you are eligible for traffic school.
If you have a noncommercial driver’s license and the court permits you to attend traffic school for an eligible offense, after completion of the course a confidential conviction will be recorded on your driving record at the DMV, but you will not receive a point on your driving record. The court may approve traffic school for a driver with a commercial driver’s license if the eligible offense occurred in a noncommercial vehicle. After completion of an approved program by a driver with a commercial driver’s license, a conviction will appear on the driving record at the DMV, but a point will not appear for the offense.
Notice: If you are eligible and decide not to attend traffic school, your automobile insurance may be adversely affected.
