A traffic school has several advantages for drivers: Defensive driving classes can reduce insurance rates. It's always good to know more about the driving laws in your area so that you can make sure you are not violating one of them and get a ticket. Twenty-three states have provisions that will allow traffic court judges to dismiss a traffic ticket if the driver completes traffic school. Before you get your hopes up about attending traffic school and having your ticket dismissed, take the following steps: 1. Check with the traffic court and make sure it is a possibility. 2. Find a state approved traffic school. 3. Take the course. 4. Present the certificate of completion to traffic court. Even if the traffic ticket is dismissed, the department of motor vehicles may still add points to your license. Check with your state DMV to find out if that will happen.
