If you live in a state with front plate law, it has to be mounted on front bumper area and visible, not on a visor, in a glove box or under seat. If they pull you over they could write a ticket, most areas don't enforce it unless your getting pulled over for a more serious violation then they'll write several tickets.
I do have a front plate on mine because it's the law in Illinois, I dont' know what the big deal is having a bracket mounted on the front bumper,our plates are mounted on the back bumper, had them on all my muscle cars in the 60' & 70's!!! Just my opinion.
