In North Carolina, if you haven't had a traffic ticket (of any kind) in the past three years, you weren't speeding in a school zone, and the ADA agrees to reduce the charge to 9 over the posted limit, then your insurance will not increase. You must plead responsible in court for this to occur after talking with the ADA. You will get points on your license for any moving violation, but speeding is only 1 or 2 points, depending on the posted limit. You will have to pay court costs and a fine set by the judge. You may hire an attorney to take care fo this for you, meaning you would not even have to show up at the courthouse on your court date. Make sure you are completely truthful with your attorney in regard to your driving record and the driving record of anyone else on your insurance.

I am an attorney in Wake County and generally the District Attorney will allow a reduction of your speed. Unless you want your insurance to increase you must get your speed reduced and not just send in the money and pay the ticket.
