The Illinois College of Optometry (ICO) is situated in Chicago, where electric scooters are generally allowed in the city. However, specific rules and regulations for their use on campus grounds would be determined by the college's policies. As with any educational institution, ICO likely has its own guidelines regarding the use of electric scooters, bicycles, and other modes of personal transportation for the safety and convenience of all students, faculty, and visitors.

For the most accurate and current information, individuals should refer to the ICO campus policies or contact the college administration directly. They typically provide details on transportation, parking, and vehicle operation on their premises, and this would include policies on electric scooters.
