I've got a few concerns of my own about this topic.
1)Does anyone know what involved in putting a "flag" on your plate so that it cannot be ran by civilians? Is there a fee for doing so?
2)Is there anything that you can legally put over your plate to protect it from being scanned by plate readers? or simply to obscure it from view?
3)For a civilian running a plate.. how large are the fees and do you contact the DMV or county clerks? Also, how lengthy are the forms and what reasons do you typically need to run a plate?
