Police are immune from citations. They cite “professional courtesy”
They speed and drive like maniacs with impunity. TV crews regularly have done stories showing cops running red lights and speeding just to go home.
Same exemption for judges, and in some places EMS people.
Tell it like it is brother.
Although it's common, I'd hardly say LEOs are "immune." The "rule" is that although you can ask for 'professional courtesy,' the officer who pulled you over is under *no* compulsion to grant said courtesy.
Usually it's granted for relatively minor traffic violations - speeding (not reckless driving), illegal U-turns, that sort of thing. It's almost never given for more serious traffic violations, and in fact, most LEOs I know get pissed when a brother LEO asks for courtesy under such circumstances.
