A traffic violation can also be a misdemeanor. Your best bet is to fully disclose the issue. Unless you are going to be driving for your employer, many employers would not hold this against you. Best of luck to you.
I agree with Mr. Vyborny--best to disclose these issues and explain them to your potential employer. As Mr. Vyborny noted, traffic violations can be misdemeanors; the point of the question on the application is to ascertain what may have happened in your past. However, many employers will not automatically discard your application for a few minor issues in your past.
