(2) operating an authorized emergency vehicle and is subject to exceptions under this subtitle.

(b) A provision of this subtitle requiring an official traffic-control device may not be enforced against an alleged violator if at the time and place of the alleged violation the device is not in proper position and sufficiently legible to an ordinarily observant person.
