You are lucky that there is no law says one can not falsely claim to be an American on the internet and Rajiv S Kahhanna is not a USA official otherwise your calling yourself "Indian American"
before your oath make you removable.
the new N400 was revised 05/31/00. It removed
"excluding traffic violation" from those criminal
record questions. The INS people you asked perhaps
did not know that.
But I don't think it is that important whether
you disclose traffic violation or not. There is
a difference in definition of what is a crime
between on book and in pratice. On book,
crimes are classified as infraction, misdeameanor,
felony. In pratice, only misdemeanor
and felony are crimes. In my opinion, disclosing
infraction like traffic violations will flood the INS
with to many frivolous truths and it will beat the
INS's original purpose to track real criminals
