The Step Up campaign is a program that helps students prevent excessive drinking, as well as sexual assault and other crimes, by teaching them how to intervene and prevent in a positive way. This is done, in part, by explaining the bystander effect. The U of M also has a TXT-U emergency notification text messaging system that sends out a notification to all faculty, staff, and students in case of emergency. Other resources help students get home safely. Calling 624-WALK secures an escort for walks to adjacent campuses and neighborhoods, and Gopher Chauffeur, a van service, offers rides near and on campus. Both are free and open to all students, staff, and faculty.
