Day Meter Permits may be used at University of Illinois meters and pay by app spaces only (excluding red short term meters). University parking spaces are marked with an orange "Block I". Any remaining campus parking meters are marked by a block I sticker and have been plugged to no longer accept coins. These permits become valid when you scratch off the month, day, and year, and place the permit on the rear-view mirror with the date displayed toward the windshield. Day Meter Permits can be purchased online or in person.
