Where exactly on my car do I put my parking permit, and does it really matter where I put it?

All parking permits should be attached to the lower LEFT hand side of your windshield. It is alright if you have other parking stickers attached there but make sure that the USC parking sticker is in that general area. You will be ticketed if the permit is not in the right area. For all hanging passes, they must be hanging from your rear view mirror while you are on campus. Failure to do so will result in a ticket.
