I've read many posts where people will give an advise to others not knowing what they are talking about. Unless you had some expirience please do not do that, we are all streassed as it is... 
After reading some advises when people would say that you would need to bring proof of paying traffic tikets, i carefully read form n-659 : Interview Document Check list. It says
"Note: Unless a traffic incident was alcohol or drug related or serious personal injury to another person occured, you DO NOT NEED TO SUBMIT DOCUMENTATION for traffic fines and incidents that did not involve an actual arrest if the only penalty was a fine less than $500 and/or points on your driver license"
It does not mean that you do need to disclose it, but anyway: do not overstress yourself...
Hope you all good luck!
