The University of Illinois' flagship campus has broadened its ban on hoverboards to cover all of its buildings and other campus facilities.
The university last week told students the two-wheeled scooters were prohibited in campus housing but widened the restriction.
The ban was put in place over fire-safety concerns related to the batteries that power hoverboards. Some have caught fire.
Students are still allowed to ride hoverboards outdoors.
The University of Illinois-Chicago is considering a similar ban. At least 20 U.S. universities have banned or restricted hoverboards in recent weeks.
