I called the bureau of investigation and they said that only misdemeanors and felonies which you WERE ARRESTED AND FINGERPRINTED FOR will show up anywhere on any CBC.....when AMCAS/secondaries ask about misdemeanors they usually are looking for DUI, MIP, DWI, reckless driving, etc.......not necessarily some ticket you paid a fine for and were never actually arrested or anything....
at the same time, just because you werent arrested doesnt mean that its not a misdemeanor...they wont really tell you if it is or not unless you call the court and ask....so I think the traffic misdemeanors which are not DUI, DWI, reckless driving, etc. arent really something you would get in trouble for not reporting
