Alex,
I'm in the application process as well, so no success story to cite, but.. Everything anyone has cited was, "Be honest." I have received 'a few' moving violations, mostly 20+ years ago. I'm not a lawyer, but the question isn't what you were convicted of, it asks if you received any traffic violations. As such, I have listed all of mine, regardless of the disposition.
I would rather be sitting across the table explaining my youthful indiscretions, rather than tap dancing why I didn't disclose xyz.., and the ensuing scrutiny of everything else I claim.
Just my take.
Good luck,
Mongo
