Driving Record USUALLY Not An Issue
Be honest.
The airline you interview at is looking at the WHOLE picture and any moving violations are "usually" not an issue.
Have the information available, how it was resolved, but offer the information ONLY IF they ask. Then tell them the truth. Don't embellish, just state the facts very briefing and then STOP talking.
Most likely it will be a non-event. There is so much more ground to cover than your driving record.
I've been through three airline interviews and they have never asked me about my driving record though in my package I had copies of my driving record from every state I lived in and there was one speeding ticket in there.
Good luck!
