First of all I do appreciate your son's service to our country, I was in the Marines for 5 years and was part of this war as well. I am now a Police officer in Nashville. I'm not an attorney however the best advice I can give would be to go talk to the DA or the traffic judge about the situation BEFORE the actual court date. They would normally dismiss it on cost or defer it for 6 months which means its dismissed but if he gets another ticket in 6 months he has to pay both. Worst case scenario would be pay the fine, YES, this does mean you are pleading guilty, but since when is manning up to something you did such a terrible thing? I can't speak for all cops, but if I stop somebody for speeding, then they were usually doing at least 15 over the speed limit. I am not fond of writing speeding tickets and the 4 years I have been on the department the only speeding tickets I have written were on felony drug cases where I wanted to show probably cause for the stop. Just my .02. Tell your son to stay safe!
