I would ask someone who knows on that one like a lawyer in maryland, I know for some people that it could be a death nail for there future career aspirations, If you were from california I would say, yes it will definately show up on your permanent criminal record, I know maryland has some of the toughest laws in the country so its probly about the same. even though they say its a "citation" it is definately not, you should fight this charge if you can dont just pay a fine (if thats what they want) any charges will show up on the criminal record check not on the dmv driving record.
