"The great majority of incarcerated citizens are facing drug and traffic violations.", InsanelyElite No, the majority (not the great) of federal prisoners are accused of drug violations. The federal prisons are a small part of the prison population. Secondly, nobody goes to prison for traffic violations unless: A) They killed somone will drinking and driving B) They have repeatedly driven without insurance, ignoring a court order. This can be up to 10 times and they may serve 30 days. C) They continue to drink and drive, risking the lives of everyone around them. This again, will still be a matter of days in prison. If you are stupied enough to continue the above over and over again, then you should get your 30 days. The real reason is that A and B generally go together, because who would keep getting pulled over time and time again if not a drunk?
