Trailers are to be placarded by the dock even the rear placard is to be switched by the dock once the driver pulls away from the dock, this goes for city drivers also, if the trailer is not placarded you are to report it to the dock supervisor.
Only at dark terminals are drivers to placard a trailer if the dock did not, and that is after you notify central.
