im in highschool right now and there is a problem with students clustering in the hallways. because of that the school is making us a project, the project is for students to make a sign that looks like a highway/traffic sign that tells students to keep on moving between classes and not stop to talk. i have a basic idea of what i want to do, i just need a second idea on what do to so i have a better view of the whole project, anyone got ideas?

my idea is to have a speed limit sign but instead of max 90km/h ill make it min 5km/h
