Just because the IO didnt ask you during interview doesnt mean that you dont have an obligation to disclose it .
filing n-400 is part of the interview what you have provided in n-400 an interview together form the basis of your approval/denial
Actually, I called the USCIS a few months before my interview and asked them if traffic tickets need to be disclosed. The customer service rep searched his computer and read to me that minor traffic tickets with fines under $500 do not need to be disclosed.
