Confusion about disclosing driving record

I am in between again looking for a new OTR position. I just paid for an MVR from the state I had a license in for most of my life and it said no citations one three month citation 7.5 yr ago ( the last 2 years my CDL in another state with a clean slate). I was surprised there were a couple of citations not on the official State MVR. This was prior to having my CDL. Last week I was vetted by a company that goes into Canada, and turned down because of a DUI 38 years ago when I was 19 and another one in 2001 that was dropped because the blood teat cleared me but the official report told that there was "no disposition" and was told the interpretation could be that it could go either way. I was under the belief it was dropped completely. How is it that my MVR shows no citations with one suspension for three months. I have already been through the vetting with Swift and was hired drove a year and I want to look for a better fit and want to disclose everything. I have had tickets 3 yr and more than 5yr I did a plea in abeyance for, which shelved it until the probation period was over then it was supposed to disappear like it never happened and for the most part has proven true except the data base the Canada uses to see you back to birth.!:smt102 From what you have read what is the proper and honest info to give on a new application.

 

Thanks FYI in Utah most Gov. entities a person can enter a plea in abeyance which I would be accessed the full fine to the citation however it is shelved for a probationary period of 3mo, 6mo 1yr. At the end of the time specified and I did not break any conditions of the probation the citation is dismissed. So if I am clear on what you have stated I would disclose these types of citations and say they were dismissed. I appreciate that if you are unfamiliar with this kind of arrangement you will not be able to answer me. It seems like some companies use different data bases because some have more informatin to share than another. I will play it safe and disclose everything saying that some have been dismissed.
