When any transportation company states no multiple "dwi", does this mean in a certain time frame? or life time? Appreciated.
It varies, but most want them to be 10 or more years. Some won't even talk to you, once they find out you've had one....in your lifetime.
They're going to interview you and ask, "Have you ever had a dui?" They won't ask if it was in the last ten years. My guess is they prefer people without any dui's. And there's no shortage of people applying either.
