This can vary between states, but do company policies allow for that variation? In many states traffic tickets are handled as civil settlements/forfeitures, so if they're not handled by the criminal courts, they wouldn't be considered "convictions." I guess I would seek clarification on whether the company policy recognizes them as such, or if they use a broader definition. In any case, it's good that you're trying to avoid the risk of misrepresenting yourself on an application, as that's usually grounds for immediate termination!
