In NH, you are not entitled to a court appointed attorney if you are only charged with a Class B Misdemeanor because you cannot be sentenced to jail - only fines or loss of license. You are charged as an adult for Disobeying An Officer because it is a motor vehicle offense.
You should hire an experienced NH criminal defense attorney who practices in the court where you are facing the charge.
Sound like you can't get an attorney for the one ticket. Are you charged with another charge or obstructing an officer?
