Yes, in the unlikely event your alleged citation is not dismissed you can take traffic school, if eligible, or have a brand new trial with a brand new Judge (Trial De Novo). Challenging your citation by a trial by written declaration increases your probability of success by over 50%. Giving you two separate opportunities/trials to have  the violation dismissed. You will not lose you ability to attend traffic school by contesting the violation. Traffic school can be taken once every 18 months (violation date to violation date). You must be traveling 25mph or under the posted speed limit and be cited for a one point violation to meet the requireds for traffic class.
