Wrong! An agency action against your license is not a civil or criminal court case; they do NOT have to send someone out to serve you or even establish that you actually received a letter. The agency just has to mail the certified letter to the address they have on file. Whether or not you refuse to take it from the postal worker or pick it up from the post office does not stop the agency from moving forward and issuing a default judgment against your license, which often involves revocation.
