Is the information obtained by running plates "always" considered public information? What information is typically displayed? Since everyone must drive and be subject to possibly having their plates ran, it seems that it could be considered an invasion of one's privacy. Have there been cases where it has been ruled this way? A few other questions of mine: 1)How difficult is it to put a "flag" on your plate so that it cannot be ran by civilians? Is there a fee? 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 much are fees and do you contact the DMV or county clerks? How lengthy are the forms and what reasons do you typically need to run a plate?
