Electric scooters are generally permitted on many college campuses; however, policies can vary widely. At the California Institute of Technology (Caltech), electric scooters might be allowed on campus grounds, but users are typically expected to adhere to specific rules and regulations designed to ensure safety and minimize disruptions. This can include wearing helmets, yielding to pedestrians, parking in designated areas, and not riding at excessive speeds.

For the most current and accurate information regarding the use of electric scooters on the Caltech campus, it's best to check the official Caltech website or contact the campus security or transportation office. They can provide the latest guidelines, any restrictions in place, and procedures for riding scooters on campus property.
