Unfortunately many people simply pay their traffic tickets because they assume there is no defense, or they just want to pay the ticket to get the case over with. However, when a traffic ticket could result in a criminal conviction, points on your license, or even jail time, fighting the ticket is absolutely necessary.
For example, sometimes prosecutors fail to understand that many Judges will approve people for defensive driving courses, despite the excessive speed in the case. These defensive driving courses ultimately result in the client's case being dismissed with no jail time or points on their license. Having a lawyer who understands this process is crucial to criminal traffic defense. It's just another example where knowledge is power.
