Ok , unfortunately coming from someone who has gone to traffic court three times... you might want to trust me on this one. Go in there 15-20mins before the trial, confident but sincere. Try to catch the officer as soon as he walks in and ask if you may speak to him. Explain to him that you understand what you did wrong and would greatly appreciate it if they just drop the points because of... insurance, driving record, etc.
Being sincere is your best bet, if you go in trying to defend yourself and make an argument the chances of you winning your case are very slim, because the officer..especially a State Trooper is well favored by the judge over you.
Best of luck! Let us know how it goes.
