JUSTIN BIEBER PULLED OVER IN BATMAN CAR

Justin Bieber narrowly dodged the cold hammer of justice this week ... TMZ has learned -- getting off with just a warning after cops pulled the 17-year-old over in his Batman-themed Cadillac.

Law enforcement sources tell us, Bieber was cruising around L.A. in a ridiculous 3-car motorcade -- with Biebs up front in a murdered out Bat-illac CTS-V ... flanked by his friends in a Range Rover and a black Rolls Royce (Sean Kingston).
