5 years clean DL sounds fine but apparently your targets are asking for more than that. Things like DUIs, suspensions, reckless driving, high-point speeding is taken as seriously as rape and bank robbery. Did they ask for ten years time or did you volunteer it? If they asked, then you had better find a job where they don't want the ten years until the ten years are behind you. I would not feel all that bad as many us have had serious DL history to work off, but you had better stick to companies wanting 3-5 years DL history until you are a bit further down the road.
