I saw on these forums that a company is marketing vinyl license plate stickers and they purport that California drivers can legally place them on their front bumpers, wondering if it is indeed legal? It's too late for me, as the front plate is welded to the bumper already.If you are in California, do not remove the front license plate or it's holder. A front license plate is required by law in California. Some people tuck the plate inside the windshield: this is also illegal. Covering the plate (front or rear) with a transparent cover is also illegal in California.
