Ok, a real important issue, if you were given a ticket, that is considered under law as a "arrest" you were allowed to just appear in court. You can not go before the judge or do a plea deal unless you are "arrested"
So yes you were charged ( arrested) for the crime.
Next a explunged record in the US is still on the record, but just not visible to non government and non national security searches.
The other issue is are they doing government searches, or will they be doing other searches, many private companies have other data bases they use. So it is very easy for an explunged item to show up though private companies. They are not required to explunge anything, Once in their records, it stays there, so if they ever got your record ( prior to being explunged) into their data bases it is there.
So until they run the check, there is no way to know what it will show up.
