In Nevada, we must carry the front plate in the car but if the machine was never drilled for a front plate, the State doesn't require you to display it. You could supplement this with a plea of possible overheating if the cop is sympathetic. I carry the plate under the floormat along with a copy of the relevant State law, as many police don't know the law that well. Never been stopped for it in any State. Applies to Judy's Z-28 (bought in NV) as well.
