polar bear
 n.— «“Whats a “Polar Bear”? My first guesses were a bear in a “plain white wrapper” (eg. white unmarked patrol car).”…“A solid white patrol car. As an example in CA the CHP has most of it’s units in the traditional black and white, but a few of their units are solid white except for the markings and insignia.”» —“Re: Slang question” by Roger Shoaf Usenet: misc.transport.trucking June 19, 2007.
