No disabled or inoperative vehicle will be parked on the campus for a period in excess of seventy-two hours without approval of parking services. Vehicles which have been parked for periods in excess of seventy-two hours and which appear to be disabled or inoperative may be impounded and stored at the expense of the registered owner. It is the responsibility of the owner or permit holder of a disabled vehicle to notify police or parking services of the vehicle's location and estimated time of removal or repair. A valid parking permit or pass must be displayed on the disabled vehicle while it is parked on campus.
