Save the campus police number as a contact in your phone. If you think you are being followed or feel unsafe, call or Facetime a friend and let him or her know, just in case. Even if you do not have someone to call, pretending someone is on the line can deter someone from thinking that you are alone. Know where the exits of buildings and parking garages are and be mindful of them. Travel in pairs after dark. Carry pepper spray, an alarm, or other self-defense tools. Take a self-defense class. Many campuses have them for free! Plus, it's a great activity to do with your friends. Most campuses have “Safety Buttons” located around campus, so learn their locations.
