Although not many people bother to contest their speeding tickets, it may be worthwhile to do so. Statistics have shown that a person who contests his or her speeding ticket has a relative amount of success in getting the speeding ticket dismissed. For example, if the officer does not appear at your scheduled hearing, you should request that the court dismiss the charges against you for a lack of evidence. Another ground for having your speeding ticket dismissed might be a problem with how the police officer calculated your speed. For instance, there might have been some reason that the police officer's radar gun did not work properly, such as another vehicle blocking it, or a lack of proper calibration. Furthermore, if you are a first-time speeding offender, you may be able to have your speeding ticket dismissed by voluntarily enrolling in a traffic safety or defensive driving program, which may result in the dismissal of your speeding ticket, provided you commit no other traffic violations for a certain period of time.
