The Barnacle is a pane of plastic that when placed will cover your windshield, immobilizing the vehicle. It is an upgrade to the standard vehicle boot, providing you the ability to pay citations over the phone or by use of a mobile application.  The Barnacle provides timeliness to those who have had their vehicles immobilized as you no longer have to wait for Parking Services to open or for an officer to respond remove a vehicle boot.  You simply pay your citations, enter in an access code, remove the Barnacle and return it to one of our four conveniently located drop boxes, giving you access to your vehicle when you need it most.
