Maryland license plate reader law

Maryland sets no limit on how long a record of where your car was can be kept. Each agency decides for itself, and some decide years. A private company logging your trips here has to delete them if you ask. You have no clear right to see what has been collected about you.

This state exempts this data from public records. The records branch dead-ends here, and asking will not change that.
