Quote:
40503. Every notice to appear or notice of violation and every
complaint or information charging a violation of any provision of
this code regulating the speed of vehicles upon a highway shall
specify the approximate speed at which the defendant is alleged to
have driven and exactly the prima facie or maximum speed limit
applicable to the highway at the time and place of the alleged
offense and shall state any other speed limit alleged to have been
exceeded if applicable to the particular type of vehicle or
combination of vehicles operated by the defendant.
So, the best advice for you is to call the court and ask them how soon you can be arraigned. Once arraigned, the ticket cannot be changed.
