Add them in there with just 1/1/year it happened or the month if you know that. I had a couple like that where I didn't know the date, just the year. I had nothing in prior to getting the hogan and interview invite, was told by people in the know that I should add them in.

They print your application straight from airline apps a few days prior to your interview, and you check it over for accuracy. Nothing was even mentioned about them during the interview.

I'm not sure if driving records are found that far back, but if you put them on a PRIA application or something like that...then they can see them there, doesn't have to just be from the DMV, previous employers may have that info you gave to them.

My advice, add them in now. If you are clean for that long, it shouldn't even be brought up in the interview.
