Again, don't volunteer information if you are not asked. I came prepared with tax transcripts and IRS agreements because I owe them some money. I also had my NJ driving record abstract from DMV and ticket dispositions from the court. When I was stopped in 1997, the NJ State Police requested for me to get a breathalyser which I agreed and passed. The only thing I got was the speeding ticket but I wasn't sure whether this will show since I didn't recall if I was fingerprinted or not. The IO during the interview didn't ask me about the IRS so I didn't tell them about the money I owed IRS which I didn't know I did till after I filed my N-400. The only thing she asked me is if I was arrested or jailed which I said no. Others questions were just standard like, am I a communist, or do I practice polygamy, etc. etc. We know the answers to those. So again, just answer the questions she asks, no more, no less. Classic example I have seen in this forum on the way you handle Q/A is this: "If the IO asks you if you know the time; the answer is YES". Hope this helps.
