A ten year old speeding ticket is not going to interfere with your ability to become a physician. I promise. Quit worrying - employers don't care one whit about traffic citations (excluding those who drive for a living.) A DUI is a whole different issue than a speeding ticket.

I imagine the Dean would have a good chuckle if you made an appointment to tell him about your speeding ticket when you were a teenager.

You truly are worrying over absolutely nothing.
