"Traffic infractions" - surely those are things like parking in the wrong place, maybe going a bit above the speed limit, maybe having the car adjusted wrong so that it's got too many emissions.
Driving when you're drunk is different. It's not a trivial technicality to be shrugged off and concealed while you're coming on as an open honest good guy crusading against all those shifty politicians with their weasel words who-wouldn't-know-the-truth-if-it-bit-them.
