What does the term first offender mean, when convicted of a 2nd Dui, where the first Dui was 13 years ago?

I am not sure I understand your question, but "first offender" is a term of art. It means that in the last five years you have not received a DUI conviction, a DUI supervision, or had a statutory summary suspension. You might consider posting another question explaining why you want to know this. ---

I agree with Mr. Richey. I am not clear what you are asking about.

I agree with Mr. Richey and Mr. Sheikh.
